  • Medicines metabolized by CYP2D6: Bupropion inhibits CYP2D6 and can increase concentrations of antidepressants (e.g., venlafaxine, nortriptyline, imipramine, desipramine, paroxetine, fluoxetine, sertraline), antipsychotics (e.g., haloperidol, risperidone, thioridazine), beta-blockers (e.g., metoprolol), and Type 1C antiarrhythmics (e.g., propafenone, flecainide). A dose reduction of these medicines may be considered when used with bupropion.
  • Dopaminergic drugs (levodopa and amantadine): CNS toxicity can occur when used concomitantly with this medicine.

Buprenorphine/naloxone (Oromucosal, Sublingual) https://drugonomy.com/2026/02/10/buprenorphine-naloxone-oromucosal-sublingual/ https://drugonomy.com/2026/02/10/buprenorphine-naloxone-oromucosal-sublingual/#respond Tue, 10 Feb 2026 22:44:14 +0000 https://drugonomy.com/?p=11277 Uses for buprenorphine/naloxone

Buprenorphine and naloxone sublingual tablet is used to treat opioid (narcotic) dependence or addiction. Buprenorphine and naloxone buccal filmsublingual film, or sublingual tablet is used for induction and maintenance treatment of opioid (narcotic) dependence. It should be used in patients who have already been treated with buprenorphine sublingual tablets.

When a narcotic medicine is used for a long time, it may become habit-forming, causing mental or physical dependence. Physical dependence may lead to withdrawal side effects if the narcotic is stopped suddenly. Severe withdrawal side effects can usually be prevented when a person is switched to buprenorphine and naloxone combination. It acts on the central nervous system (CNS) to help prevent the withdrawal side effects.

This medicine is available only with your doctor’s prescription.

Before using buprenorphine/naloxone

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of buprenorphine and naloxone buccal filmsublingual film, or sublingual tablet in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of buprenorphine and naloxone combination in the elderly. However, elderly patients are more likely to have age-related kidney, liver, heart, or lung problems, which may require caution and an adjustment in the dose for patients receiving buprenorphine and naloxone combination.

Breast Feeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Precautions while using buprenorphine/naloxone

It is very important that your doctor check your progress while you are using this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it. Blood tests may be needed to check for unwanted effects.

Do not use this medicine if you have used an MAO inhibitor (MAOI) (eg, isocarboxazid [Marplan®], linezolid [Zyvox®], phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]) within the past 14 days.

It is against the law and dangerous for anyone else to use your medicine. Keep your unused films or tablets in a safe and secure place. People who are addicted to drugs might want to steal this medicine.

This medicine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.

Using too much of this medicine may cause an overdose, which can be life-threatening. Symptoms of an overdose include: blurred vision, confusion, difficult or trouble breathing, dizziness, faintness, or lightheadedness when getting up suddenly from a lying position or sitting position, irregular, fast or slow, or shallow breathing, pale or blue lips, fingernails, or skin, pinpoint pupils, sleepiness, sweating, unusual tiredness or weakness. In case of an overdose, call your doctor right away. Your doctor may also give naloxone to treat an overdose.

This medicine may cause sleep-related breathing problems (eg, sleep apnea, sleep-related hypoxemia). Your doctor may decrease your dose if you have sleep apnea (stop breathing for short periods during sleep) while using this medicine.

Buprenorphine https://drugonomy.com/2026/02/10/buprenorphine/ https://drugonomy.com/2026/02/10/buprenorphine/#respond Tue, 10 Feb 2026 22:33:00 +0000 https://drugonomy.com/?p=11273 What is buprenorphine?

Buprenorphine is an opioid medication used to treat opioid use disorder (OUD), acute pain, and chronic pain. 

Buprenorphine is used for opioid addiction to reduce cravings and withdrawal symptoms without causing euphoria or dangerous side effects and helps prevent relapse. It works by being a substitute for the drug being abused, so the patient has minimal discomfort, which allows the patient to focus on their recovery. Buprenorphine for OUD is used as part of a complete treatment program that also includes counseling and behavioral therapy.

For opioid use disorder, buprenorphine is available as long-acting injections (Sublocade, Brixadi) and sublingual tablets (Subutex discontinued, generics available). 

Buprenorphine is used to treat acute pain that is severe enough to require an opioid analgesic and moderate to severe chronic pain that is not controlled by other medicines. For chronic around-the-clock pain, it is available as buprenorphine skin patches (Butrans) and buprenorphine buccal films (Belbuca), and for acute pain is available as an injection (Buprenex).

Buprenorphine-naloxone combinations are also available to be used for opioid addication and include sublingual film (Bunavail), sublingual film and sublingual tablets (Suboxone), and sublingual tablets (Zubsolv).

Buprenorphine’s mechanism of action is that is a partial agonist at the mu-opioid receptor and an antagonist at the kappa-opioid receptor.

Is buprenorphine a controlled substance?

Yes, buprenorphine is a Schedule III controlled drug, which means it has a potential for abuse more than those in Schedules 4 and 5. If abused, it may lead to moderate or low physical dependence or high psychological dependence.

Warnings

MISUSE OF OPIOID MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep buprenorphine in a place where others cannot get to it.
Patient Access to Naloxone for the Emergency Treatment of Opioid Overdose. Patients should have access to naloxone to treat opioid overdose based on the patient’s risk factors for overdose, such as currently using a CNS depressant, a history of an opioid use disorder, or previous opioid overdose.  Having naloxone available is important if the patient has household members (including children) or other close contacts at risk for accidental exposure or overdose.

Taking this medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.

Fatal side effects can occur if you use this medication with alcohol or with other drugs that cause drowsiness or slow your breathing.

Before taking this medicine

You should not use this medicine if you are allergic to buprenorphine or:

  • If you have used another narcotic drug within the past 4 hours.

To make sure this medication is safe for you, tell your doctor if you have ever had:

  • methadone treatment;
  • breathing problems, sleep apnea;
  • abnormal curvature of the spine that affects breathing;
  • liver disease (especially hepatitis B or C);
  • kidney disease;
  • enlarged prostate, urination problems;
  • a head injury or brain tumor;
  • alcoholism, hallucinations, mental illness; or
  • problems with your stomach, gallbladder, adrenal gland, or thyroid.

Pregnancy

If you use buprenorphine while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks.

Infertility

Chronic use of opioids may cause reduced fertility in females and males of reproductive potential. It is not known whether these effects on fertility are reversible 

Breastfeeding

Buprenorphine can pass into breast milk and may cause drowsiness and breathing problems in a nursing baby. Ask your doctor about any risk to your baby.

How should I take buprenorphine?

Use buprenorphine exactly as it was prescribed for you. Follow the directions on your prescription label and read all medication guides. Your doctor may occasionally change your dose. Never use this medication in larger amounts, or for longer than prescribed.

Opioid Use Disorder

Buprenorphine Sublingual (for OUD)

Buprenorphine sublingual is usually taken only at the start of treatment for addiction (induction phase). Most people are later switched to long-acting buprenorphine (Sublocade injection or Brixadi injection) or another medicine that contains buprenorphine with naloxone (Bunavail, Suboxone, Zubsolv). You may receive your first doses of buprenorphine sublingual in a hospital or clinic setting until your condition improves. Use dry hands when handling the tablet. Place the tablet under your tongue and allow it to dissolve with your mouth closed. Do not chew the tablet or swallow it whole. If your doctor has prescribed more than 2 tablets per dose, place the correct number of tablets under your tongue at the same time and allow them to dissolve completely. Do not eat or drink anything until the tablet has completely dissolved in your mouth. Never crush or break a pill to inhale the powder or mix it into a liquid to inject the drug into your vein. Doing so could result in death.

Extended-release buprenorphine subcutaneous injection (for OUD)

Buprenorphine extended-release injection is given subcutaneously (just under the skin). Sublocade and Brixadi can be given in the abdomen, thigh, buttock, or the back of the upper arm. 

Sublocade should only be used when patients have received treatment with at least one dose (eg, 4 mg) of an oral transmucosal (used under the tongue or inside the cheek) buprenorphine-containing medicine. Sublocade is injected as a liquid. After the injection, Sublocade changes to a solid form called a depot. The depot may be seen or felt as a small bump under your skin at the injection site on your abdomen, thigh, buttock, or back of the upper arm, for several weeks. The depot will get smaller over time. Do not try to remove the depot, and do not rub or massage the injection site. Sublocade is part of a complete treatment plan that should include counseling.

Brixadi should only be used if you are currently receiving buprenorphine treatment or if your healthcare provider has given you a test dose of buprenorphine first to see if you are able to tolerate it. If you are new to Brixadi treatment, the upper arm should only be used after 4 doses of Brixadi in your buttock, thigh, or stomach. Brixadi is injected as a liquid; after the injection, the liquid changes to a gel form called a depot. The depot is not always felt under the skin. Do not try to remove the depot. Brixadi is part of a complete treatment plan that should include counseling.

Pain

Buprenex (buprenorphine injection) is used for pain, it is given by deep intramuscular or slow (over at least 2 minutes) intravenous injection at up to 6-hour intervals, as needed.

Butrans skin patch is used for chronic around-the-clock pain. It is applied once a week and worn continuously for 1 week. Do not change your dose. Apply Butrans exactly as prescribed by your healthcare provider. Your doctor will prescribe you the lowest effective dose for the shortest time needed. Do not take hot baths or sunbathe, use hot tubs, saunas, heating pads, electric blankets, heated waterbeds, or tanning lamps as these can cause an overdose that can lead to death.

Belbuca buccal films are used for around-the-clock treatment of moderate to severe chronic pain. Using a finger, place the yellow side of the Belbuca buccal film against the inside of your moistened cheek. Press and hold the Belbuca buccal film in place for 5 seconds and then take your finger away. Once in place, the film will dissolve completely in about 30 minutes. Do not eat or drink anything until the Belbuca film has completely dissolved in your mouth. Rinse your mouth with water after the medicine dissolves. Wait one hour after the film dissolves to brush your teeth to prevent damage to the teeth and gums. Do not chew the Belbuca film or swallow it whole. You should receive regular dental checkups while using Belbuca.

Warnings

Tell your doctor if you have ever had an allergic reaction to any type of numbing medicine.

Some epidural numbing medications can have long-lasting or permanent effects on certain body processes such as sexual function, bowel or bladder control, and movement or feeling in your legs or feet. Talk with your doctor about your specific risk of nerve damage from bupivacaine.

Before taking this medicine

Tell your doctor if you have ever had an allergic reaction to any type of numbing medicine, or if you’ve ever had:

  • anemia (lack of red blood cells);
  • kidney or liver disease;
  • a bleeding or blood clotting disorder;
  • syphilis, polio, a brain or spinal cord tumor;
  • numbness or tingling;
  • chronic back pain, headache caused by surgery;
  • low or high blood pressure;
  • abnormal curvature of the spine; or
  • arthritis.

It is not known whether bupivacaine will harm an unborn baby. If you are not receiving bupivacaine during childbirth, tell your doctor if you are pregnant.

It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.

How is bupivacaine given?

Bupivacaine is injected through a needle directly into or near the area to be numbed. You will receive this injection in a dental or hospital setting.

For an epidural, bupivacaine is given as an injection through a needle placed into an area of your middle or lower back near your spine.

Your breathing, blood pressure, oxygen levels, or other vital signs will be watched closely.

For a dental procedure, bupivacaine is injected directly into the mouth near the tooth or teeth your dentist will be working on.

Some epidural numbing medications can have long-lasting or permanent effects on certain body processes such as sexual function, bowel or bladder control, and movement or feeling in your legs or feet. Talk with your doctor about your specific risk of nerve damage from bupivacaine.

What happens if I miss a dose?

Since bupivacaine is given as needed before a surgery or dental procedure, you are not likely to be on a dosing schedule.

What happens if I overdose?

Since bupivacaine is given in a medical setting, you will be watched closely to make sure you do not receive too much of bupivacaine. Your caregivers will quickly treat you if you have overdose symptoms.

What should I avoid after receiving bupivacaine?

This medicine can cause numbness over a large portion of your body. After an epidural you not be able to feel or move your lower body. Take care to avoid injury while you are still numb.

After a dental procedure, avoid eating, chewing gum, or drinking a hot beverage until your mouth is no longer numb.

Bunavail https://drugonomy.com/2026/02/09/bunavail/ https://drugonomy.com/2026/02/09/bunavail/#respond Mon, 09 Feb 2026 21:49:02 +0000 https://drugonomy.com/?p=11264 What is Bunavail?

Bunavail buccal films contains a combination of buprenorphine and naloxone. Buprenorphine is an opioid medication, sometimes called a narcotic. Naloxone blocks the effects of opioid medication, including pain relief or feelings of well-being that can lead to opioid abuse.

Bunavail buccal films are used to treat opioid addiction.

Bunavail is not for use as a pain medication.

Warnings

MISUSE OF OPIOID MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it.

Using Bunavail during pregnancy may cause life-threatening withdrawal symptoms in the newborn.

Fatal side effects can occur if you use Bunavail with alcohol, or with other drugs that cause drowsiness or slow your breathing.

Before taking this medicine

You should not use Bunavail if you are allergic to buprenorphine or naloxone (Narcan).

To make sure Bunavail is safe for you, tell your doctor if you have ever had:

  • tooth problems, including a history of cavities;
  • breathing problems, sleep apnea;
  • enlarged prostate, urination problems;
  • liver or kidney disease;
  • abnormal curvature of the spine that affects breathing;
  • problems with your gallbladder, adrenal gland, or thyroid;
  • a head injury, brain tumor, or seizures; or
  • alcoholism or drug addiction.

If you use Bunavail while you are pregnant, your baby could become dependent on this medicine. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on opioids may need medical treatment for several weeks.

Ask a doctor before using Bunavail if you are breastfeeding. Tell your doctor if you notice severe drowsiness or slow breathing in the nursing baby.

How should I take Bunavail?

Use Bunavail buccal films exactly as prescribed by your doctor. Follow the directions on your prescription label and read all medication guides. Never use Bunavail in larger amounts, or for longer than prescribed. Tell your doctor if you feel an increased urge to use more of this medicine.

Never share Bunavail with another person, especially someone with a history of drug abuse or addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medicine in a place where others cannot get to it. Selling or giving away Bunavail is against the law.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Rinse your mouth with water after the Bunavail film dissolves. Wait one hour after the medicine dissolves to brush your teeth to prevent damage to the teeth and gums. You should receive regular dental checkups while using Bunavail.

If you switch between medicines containing buprenorphine, you may not use the same dose for each one. Follow all directions carefully.

Do not stop using Bunavail suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.

You will need frequent blood tests to check your liver function.

All your medical care providers should know that you are being treated for opioid addiction, and that you take Bunavail. Make sure your family members know how to provide this information in case they need to speak for you during an emergency.

Never crush or break a Bunavail pill to inhale the powder or mix it into a liquid to inject the drug into your vein. This practice has resulted in death.

Store Bunavail films in the foil pouch at room temperature, away from moisture and heat. Discard an empty pouch in a place children and pets cannot get to. Keep track of your medicine. You should be aware if anyone is using it improperly or without a prescription.

Do not keep leftover opioid medication. Just one dose can cause death in someone using Bunavail accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, remove any unused films from the foil pack and flush the films down the toilet. Throw the empty foil pack into the trash.

Dosing information

Usual Adult Dose for Opiate Dependence: Buprenorphine monotherapy is generally used for induction. Bunavail may be used for induction in patients dependent on heroin or short-acting opioid products. Note – one Bunavail 4.2 mg/0.7 mg buccal film provides the equivalent buprenorphine exposure to one Suboxone 8 mg/2 mg sublingual tablet.

INDUCTION dose: Day 1: Initial dose: 2.1 mg/0.3 mg buccally; followed in intervals of approximately 2 hours with additional doses to a total dose of 4.2 mg/0.7 mg to control acute withdrawal symptoms
Day 2: a single dose up to 8.4 mg/1.4 mg buccally.

MAINTENANCE Treatment: Doses should be adjusted to a level that holds the patient in treatment and suppresses opioid withdrawal signs and symptoms; doses should be titrated to clinical effectiveness as rapidly as possible as gradual titration may lead to higher drop-out rates.
-Progressively adjust in increments/decrements of 2.1 mg/0.3 mg to a level that holds the patient in treatment and suppresses opioid withdrawal signs and symptoms.
-Recommended target dose: 8.4 mg/1.4 mg buccally once a day; range 2.1 mg/0.3 mg to 12.6 mg/2.1 mg
Maximum dose: 12.6 mg/ 2.1 mg buccally once a day.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line . An opioid overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include severe drowsiness, pinpoint pupils, slow breathing, or no breathing.

What should I avoid while taking Bunavail?

Do not drink alcohol. Dangerous side effects or death could occur.

Avoid driving or operating machinery until you know how Bunavail will affect you. Dizziness or severe drowsiness can cause falls, accidents, or severe injuries.

Buprenorphine and naloxone side effects

Get emergency medical help if you have signs of an allergic reaction to Bunavail: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Opioid medicine can slow or stop your breathing, and death may occur. A person caring for you should seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.

Call your doctor at once or seek emergency medical attention if you have:

  • any problems with your teeth or gums;
  • weak or shallow breathing, breathing that stops during sleep;
  • a light-headed feeling, like you might pass out;
  • confusion, loss of coordination, extreme weakness;
  • blurred vision, slurred speech;
  • liver problems – upper stomach pain, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);
  • high levels of serotonin in the body – agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, diarrhea;
  • low cortisol levels – nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness; or
  • opioid withdrawal symptoms – shivering, goose bumps, increased sweating, feeling hot or cold, runny nose, watery eyes, diarrhea, muscle pain.

Serious breathing problems may be more likely in older adults and those who are debilitated or have wasting syndrome or chronic breathing disorders.

Common Bunavail side effects may include:

  • dizziness, drowsiness, blurred vision, feeling drunk, trouble concentrating;
  • withdrawal symptoms;
  • tongue pain, redness or numbness inside your mouth;
  • nausea, vomiting, constipation;
  • headache, back pain;
  • fast or pounding heartbeats, increased sweating; or
  • sleep problems (insomnia).

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects.

What other drugs will affect Bunavail?

You may have breathing problems or withdrawal symptoms if you start or stop taking certain other medicines. Tell your doctor if you also use an antibiotic, antifungal medication, heart or blood pressure medication, seizure medication, or medicine to treat HIV or hepatitis C.

Opioid medication can interact with many other drugs and cause dangerous side effects or death. Be sure your doctor knows if you also use:

  • cold or allergy medicines, bronchodilator asthma/COPD medication, or a diuretic (“water pill”);
  • medicines for motion sickness, irritable bowel syndrome, or overactive bladder;
  • other opioids – opioid pain medicine or prescription cough medicine;
  • a sedative like Valium – diazepam, alprazolam, lorazepam, Xanax, Klonopin, Ativan, and others;
  • drugs that make you sleepy or slow your breathing – a sleeping pill, muscle relaxer, medicine to treat mood disorders or mental illness; or
  • drugs that affect serotonin levels in your body – a stimulant, or medicine for depression, Parkinson’s disease, migraine headaches, serious infections, or nausea and vomiting.

Bumex https://drugonomy.com/2026/02/09/bumex/ https://drugonomy.com/2026/02/09/bumex/#respond Mon, 09 Feb 2026 21:39:40 +0000 https://drugonomy.com/?p=11261 Bumex Description

Bumex ®(bumetanide) is a loop diuretic available as 0.5 mg (light green), 1 mg (yellow) and 2 mg (peach) tablets for oral administration; each tablet also contains anhydrous lactose, magnesium stearate, microcrystalline cellulose, pregelatinized starch and talc, with the following dye systems: 0.5 mg—D&C Yellow No. 10 aluminum lake and FD&C Blue No. 1 aluminum lake; 1 mg—D&C Yellow No. 10 aluminum lake; 2 mg—red iron oxide.

Chemically, bumetanide is 3-(butylamino)-4-phenoxy-5-sulfamoylbenzoic acid. It is a practically white powder having a calculated molecular weight of 364.42, and the following structural formula:

structural formula

FDA-approved impurity specifications differ from the USP.

Bumex – Clinical Pharmacology

Bumex is a loop diuretic with a rapid onset and short duration of action. Pharmacological and clinical studies have shown that 1 mg Bumex has a diuretic potency equivalent to approximately 40 mg furosemide. The major site of Bumex action is the ascending limb of the loop of Henle.

The mode of action has been determined through various clearance studies in both humans and experimental animals. Bumex inhibits sodium reabsorption in the ascending limb of the loop of Henle, as shown by marked reduction of free-water clearance (CH 2O) during hydration and tubular free-water reabsorption (T CH 2O) during hydropenia. Reabsorption of chloride in the ascending limb is also blocked by Bumex, and Bumex is somewhat more chloruretic than natriuretic.

Potassium excretion is also increased by Bumex, in a dose-related fashion.

Bumex may have an additional action in the proximal tubule. Since phosphate reabsorption takes place largely in the proximal tubule, phosphaturia during Bumex induced diuresis is indicative of this additional action. This is further supported by the reduction in the renal clearance of Bumex by probenecid, associated with diminution in the natriuretic response. This proximal tubular activity does not seem to be related to an inhibition of carbonic anhydrase. Bumex does not appear to have a noticeable action on the distal tubule.

Bumex decreases uric acid excretion and increases serum uric acid. Following oral administration of Bumex the onset of diuresis occurs in 30 to 60 minutes. Peak activity is reached between 1 and 2 hours. At usual doses (1 mg to 2 mg) diuresis is largely complete within 4 hours; with higher doses, the diuretic action lasts for 4 to 6 hours. Diuresis starts within minutes following an intravenous injection and reaches maximum levels within 15 to 30 minutes.

Several pharmacokinetic studies have shown that bumetanide, administered orally or parenterally, is eliminated rapidly in humans, with a half-life of between 1 and 1½ hours. Plasma protein-binding is in the range of 94% to 96%.

Oral administration of carbon-14 labeled Bumex to human volunteers revealed that 81% of the administered radioactivity was excreted in the urine, 45% of it as unchanged drug. Urinary and biliary metabolites identified in this study were formed by oxidation of the N-butyl side chain. Biliary excretion of Bumex amounted to only 2% of the administered dose.

Pediatric Pharmacology

Elimination of bumetanide appears to be considerably slower in neonatal patients compared with adults, possibly because of immature renal and hepatobiliary function in this population. Small pharmacokinetic studies of intravenous bumetanide in preterm and full-term neonates with respiratory disorders have reported an apparent half-life of approximately 6 hours, with a range up to 15 hours and a serum clearance ranging from 0.2 mL/min/kg to 1.1 mL/min/kg. In a population of neonates receiving bumetanide for volume overload, mean serum clearance rates were 2.2 mL/min/kg in patients less than 2 months of age and 3.8 mL/min/kg in patients aged 2 to 6 months. Mean serum half-life of bumetanide was 2.5 hours and 1.5 hours in patients aged less than 2 months and those aged 2 to 6 months, respectively. Elimination half-life decreased considerably during the first month of life, from a mean of approximately 6 hours at birth to approximately 2.4 hours at 1 month of age.

In preterm neonates, mean serum concentrations following a single 0.05 mg/kg dose ranged from 126 μg/L at 1 hour to 57 μg/L at 8 hours. In another study, mean serum concentrations following a single 0.05 mg/kg dose were 338 ng/mL at 30 minutes and 176 ng/mL after 4 hours. A single dose of 0.1 mg/kg produced mean serum levels of 314 ng/mL at 1 hour, and 195 ng/mL at 6 hours. Mean volume of distribution in neonates and infants has been reported to range from 0.26 L/kg to 0.39 L/kg.

The degree of protein binding of bumetanide in cord sera from healthy neonates was approximately 97%, suggesting the potential for bilirubin displacement. A study using pooled sera from critically ill neonates found that bumetanide at concentrations of 0.5 μg/mL to 50 μg/mL, but not 0.25 μg/mL, caused a linear increase in unbound bilirubin concentrations.

In 56 infants aged 4 days to 6 months, bumetanide doses ranging from 0.005 mg/kg to 0.1 mg/kg were studied for pharmacodynamic effect. Peak bumetanide excretion rates increased linearly with increasing doses of drug. Maximal diuretic effect was observed at a bumetanide excretion rate of about 7 μg/kg/h, corresponding to doses of 0.035 mg/kg to 0.040 mg/kg. Higher doses produced a higher bumetanide excretion rate but no increase in diuretic effect. Urine flow rate peaked during the first hour after drug administration in 80% of patients and by 3 hours in all patients.

Geriatric Pharmacology

In a group of ten geriatric subjects between the ages of 65 and 73 years, total bumetanide clearance was significantly lower (1.8 ± 0.3 mL/min·kg) compared with younger subjects (2.9 ± 0.2 mL/min·kg) after a single oral bumetanide 0.5 mg dose. Maximum plasma concentrations were higher in geriatric subjects (16.9 ± 1.8 ng/mL) compared with younger subjects (10.3 ± 1.5 ng/mL). Urine flow rate and total excretion of sodium and potassium were increased less in the geriatric subjects compared with younger subjects, although potassium excretion and fractional sodium excretion were similar between the two age groups. Nonrenal clearance, bioavailability, and volume of distribution were not significantly different between the two groups.

Indications and Usage for Bumex

Bumex tablets are indicated for the treatment of edema associated with congestive heart failure, hepatic and renal disease, including the nephrotic syndrome.

Almost equal diuretic response occurs after oral and parenteral administration of bumetanide. Therefore, if impaired gastrointestinal absorption is suspected or oral administration is not practical, bumetanide should be given by the intramuscular or intravenous route.

Successful treatment with Bumex tablets following instances of allergic reactions to furosemide suggests a lack of cross-sensitivity.

Contraindications

Bumex is contraindicated in anuria. Although Bumex can be used to induce diuresis in renal insufficiency, any marked increase in blood urea nitrogen or creatinine, or the development of oliguria during therapy of patients with progressive renal disease, is an indication for discontinuation of treatment with Bumex. Bumex is also contraindicated in patients in hepatic coma or in states of severe electrolyte depletion until the condition is improved or corrected. Bumex is contraindicated in patients hypersensitive to this drug.

Warnings

Volume and Electrolyte Depletion

The dose of Bumex should be adjusted to the patient’s need. Excessive doses or too frequent administration can lead to profound water loss, electrolyte depletion, dehydration, reduction in blood volume and circulatory collapse with the possibility of vascular thrombosis and embolism, particularly in elderly patients.

Hypokalemia

Hypokalemia can occur as a consequence of Bumex administration. Prevention of hypokalemia requires particular attention in the following conditions: patients receiving digitalis and diuretics for congestive heart failure, hepatic cirrhosis and ascites, states of aldosterone excess with normal renal function, potassium-losing nephropathy, certain diarrheal states, or other states where hypokalemia is thought to represent particular added risks to the patient, i.e., history of ventricular arrhythmias.

In patients with hepatic cirrhosis and ascites, sudden alterations of electrolyte balance may precipitate hepatic encephalopathy and coma. Treatment in such patients is best initiated in the hospital with small doses and careful monitoring of the patient’s clinical status and electrolyte balance. Supplemental potassium and/or spironolactone may prevent hypokalemia and metabolic alkalosis in these patients.

Ototoxicity

In cats, dogs and guinea pigs, bumetanide has been shown to produce ototoxicity. In these test animals bumetanide was 5 to 6 times more potent than furosemide and, since the diuretic potency of bumetanide is about 40 to 60 times furosemide, it is anticipated that blood levels necessary to produce ototoxicity will rarely be achieved. The potential exists, however, and must be considered a risk of intravenous therapy, especially at high doses, repeated frequently in the face of renal excretory function impairment. Potentiation of aminoglycoside ototoxicity has not been tested for bumetanide. Like other members of this class of diuretics, bumetanide probably shares this risk.

Allergy to Sulfonamides

Patients allergic to sulfonamides may show hypersensitivity to Bumex.

Thrombocytopenia

Since there have been rare spontaneous reports of thrombocytopenia from postmarketing experience, patients should be observed regularly for possible occurrence of thrombocytopenia.

Precautions

General

Serum potassium should be measured periodically and potassium supplements or potassium sparing diuretics added if necessary. Periodic determinations of other electrolytes are advised in patients treated with high doses or for prolonged periods, particularly in those on low-salt diets.

Hyperuricemia may occur; it has been asymptomatic in cases reported to date. Reversible elevations of the BUN and creatinine may also occur, especially in association with dehydration and particularly in patients with renal insufficiency. Bumex may increase urinary calcium excretion with resultant hypocalcemia.

Diuretics have been shown to increase the urinary excretion of magnesium; this may result in hypomagnesemia.

Laboratory Tests

Studies in normal subjects receiving Bumex revealed no adverse effects on glucose tolerance, plasma insulin, glucagon and growth hormone levels, but the possibility of an effect on glucose metabolism exists. Periodic determinations of blood sugar should be done, particularly in patients with diabetes or suspected latent diabetes.

Patients under treatment should be observed regularly for possible occurrence of blood dyscrasias, liver damage or idiosyncratic reactions, which have been reported occasionally in foreign marketing experience. The relationship of these occurrences to Bumex use is not certain.

Drug Interactions

Drugs with Ototoxic Potential 

Especially in the presence of impaired renal function, the use of parenterally administered bumetanide in patients to whom aminoglycoside antibiotics are also being given should be avoided, except in life-threatening conditions.

Drugs with Nephrotoxic Potential

There has been no experience with the concurrent use of Bumex with drugs known to have a nephrotoxic potential. Therefore, the simultaneous administration of these drugs should be avoided.

Lithium

Lithium should generally not be given with diuretics (such as Bumex) because they reduce its renal clearance and add a high risk of lithium toxicity.

Probenecid

Pretreatment with probenecid reduces both the natriuresis and hyperreninemia produced by Bumex. This antagonistic effect of probenecid on Bumex natriuresis is not due to a direct action on sodium excretion but is probably secondary to its inhibitory effect on renal tubular secretion of bumetanide. Thus, probenecid should not be administered concurrently with Bumex.

Indomethacin

Indomethacin blunts the increases in urine volume and sodium excretion seen during Bumex treatment and inhibits the bumetanide-induced increase in plasma renin activity. Concurrent therapy with Bumex is thus not recommended.

Antihypertensives

Bumex may potentiate the effect of various antihypertensive drugs, necessitating a reduction in the dosage of these drugs.

Digoxin

Interaction studies in humans have shown no effect on digoxin blood levels.

Anticoagulants

Interaction studies in humans have shown Bumex to have no effect on warfarin metabolism or on plasma prothrombin activity.

Carcinogenesis, Mutagenesis and Impairment of Fertility

Bumex was devoid of mutagenic activity in various strains of Salmonella typhimurium when tested in the presence or absence of an in vitrometabolic activation system. An 18-month study showed an increase in mammary adenomas of questionable significance in female rats receiving oral doses of 60 mg/kg/day (2000 times a 2-mg human dose). A repeat study at the same doses failed to duplicate this finding.

Reproduction studies were performed to evaluate general reproductive performance and fertility in rats at oral dose levels of 10, 30, 60 or 100 mg/kg/day. The pregnancy rate was slightly decreased in the treated animals; however, the differences were small and not statistically significant.

Pregnancy

Teratogenic Effects

Bumex is neither teratogenic nor embryocidal in mice when given in doses up to 3400 times the maximum human therapeutic dose.

Bumex has been shown to be nonteratogenic, but it has a slight embryocidal effect in rats when given in doses of 3400 times the maximum human therapeutic dose and in rabbits at doses of 3.4 times the maximum human therapeutic dose. In one study, moderate growth retardation and increased incidence of delayed ossification of sternebrae were observed in rats at oral doses of 100 mg/kg/day, 3400 times the maximum human therapeutic dose. These effects were associated with maternal weight reductions noted during dosing. No such adverse effects were observed at 30 mg/kg/day (1000 times the maximum human therapeutic dose). No fetotoxicity was observed at 1000 to 2000 times the human therapeutic dose.

In rabbits, a dose-related decrease in litter size and an increase in resorption rate were noted at oral doses of 0.1 mg/kg/day and 0.3 mg/kg/day (3.4 and 10 times the maximum human therapeutic dose). A slightly increased incidence of delayed ossification of sternebrae occurred at 0.3 mg/kg/day; however, no such adverse effects were observed at the dose of 0.03 mg/kg/day. The sensitivity of the rabbit to Bumex parallels the marked pharmacologic and toxicologic effects of the drug in this species.

Bumex was not teratogenic in the hamster at an oral dose of 0.5 mg/kg/day (17 times the maximum human therapeutic dose). Bumetanide was not teratogenic when given intravenously to mice and rats at doses up to 140 times the maximum human therapeutic dose.

There are no adequate and well-controlled studies in pregnant women. A small investigational experience in the and marketing experience in other countries to date have not indicated any evidence of adverse effects on the fetus, but these data do not rule out the possibility of harmful effects. Bumex should be given to a pregnant woman only if the potential benefit justifies the potential risk to the fetus.

Nursing Mothers

It is not known whether this drug is excreted in human milk. As a general rule, nursing should not be undertaken while the patient is on Bumex since it may be excreted in human milk.

Pediatric Use

Safety and effectiveness in pediatric patients below the age of 18 have not been established.

In vitrostudies using pooled sera from critically ill neonates have shown bumetanide to be a potent displacer of bilirubin . The administration of bumetanide could present a particular concern if given to critically ill or jaundiced neonates at risk for kernicterus.

Geriatric Use

Clinical studies of Bumex did not include sufficient numbers of subjects aged 65 and over to determine whether they responded differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.

This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

Adverse Reactions/Side Effects

The most frequent clinical adverse reactions considered probably or possibly related to Bumex are muscle cramps (seen in 1.1% of treated patients), dizziness (1.1%), hypotension (0.8%), headache (0.6%), nausea (0.6%) and encephalopathy (in patients with pre-existing liver disease) (0.6%). One or more of these adverse reactions have been reported in approximately 4.1% of patients treated with Bumex.

Serious skin reactions (i.e., Stevens-Johnson syndrome, toxic epidermal necrolysis) have been reported in association with bumetanide use.

Less frequent clinical adverse reactions to Bumex are impaired hearing (0.5%), pruritus (0.4%), electrocardiogram changes (0.4%), weakness (0.2%), hives (0.2%), abdominal pain (0.2%), arthritic pain (0.2%), musculoskeletal pain (0.2%), rash (0.2%) and vomiting (0.2%). One or more of these adverse reactions have been reported in approximately 2.9% of patients treated with Bumex.

Other clinical adverse reactions, which have each occurred in approximately 0.1% of patients, are vertigo, chest pain, ear discomfort, fatigue, dehydration, sweating, hyperventilation, dry mouth, upset stomach, renal failure, asterixis, itching, nipple tenderness, diarrhea, premature ejaculation and difficulty maintaining an erection.

Laboratory abnormalities reported have included hyperuricemia (in 18.4% of patients tested), hypochloremia (14.9%), hypokalemia (14.7%), azotemia (10.6%), hyponatremia (9.2%), increased serum creatinine (7.4%), hyperglycemia (6.6%), and variations in phosphorus (4.5%), CO content (4.3%), bicarbonate (3.1%) and calcium (2.4%). Although manifestations of the pharmacologic action of Bumex, these conditions may become more pronounced by intensive therapy.

Also reported have been thrombocytopenia (0.2%) and deviations in hemoglobin (0.8%), prothrombin time (0.8%), hematocrit (0.6%), WBC (0.3%) and differential counts (0.1%). There have been rare spontaneous reports of thrombocytopenia from postmarketing experience.

Diuresis induced by Bumex may also rarely be accompanied by changes in LDH (1.0%), total serum bilirubin (0.8%), serum proteins (0.7%), SGOT (0.6%), SGPT (0.5%), alkaline phosphatase (0.4%), cholesterol (0.4%) and creatinine clearance (0.3%). Increases in urinary glucose (0.7%) and urinary protein (0.3%) have also been seen.

Overdosage

Overdosage can lead to acute profound water loss, volume and electrolyte depletion, dehydration, reduction of blood volume and circulatory collapse with a possibility of vascular thrombosis and embolism. Electrolyte depletion may be manifested by weakness, dizziness, mental confusion, anorexia, lethargy, vomiting and cramps. Treatment consists of replacement of fluid and electrolyte losses by careful monitoring of the urine and electrolyte output and serum electrolyte levels.

Bumex Dosage and Administration

Individualize dosage with careful monitoring of patient response.

Oral Administration

The usual total daily dosage of Bumex tablets is 0.5 mg to 2 mg and in most patients is given as a single dose.

If the diuretic response to an initial dose of Bumex tablets is not adequate, in view of its rapid onset and short duration of action, a second or third dose may be given at 4- to 5-hour intervals up to a maximum daily dose of 10 mg. An intermittent dose schedule, whereby Bumex tablets are given on alternate days or for 3 to 4 days with rest periods of 1 to 2 days in between, is recommended as the safest and most effective method for the continued control of edema. In patients with hepatic failure, keep the dosage to a minimum.

Because cross-sensitivity with furosemide has rarely been observed, bumetanide can be substituted at approximately a 1:40 ratio of bumetanide in proportion to furosemide in patients allergic to furosemide.

Parenteral Administration

Bumetanide injection may be administered parenterally (intravenously and intramuscularly) to patients in whom gastrointestinal absorption may be impaired or in whom oral administration is not practical.

Terminate parenteral treatment and institute oral treatment as soon as possible.

Bumetanide https://drugonomy.com/2026/02/09/bumetanide/ https://drugonomy.com/2026/02/09/bumetanide/#respond Mon, 09 Feb 2026 21:33:13 +0000 https://drugonomy.com/?p=11257 Bumetanide Description

Bumetanide is a loop diuretic, available as 4 mL vials and 10 mL vials (0.25 mg/mL) for intravenous or intramuscular injection as a sterile solution.

Each mL contains 0.25 mg bumetanide compounded with 0.85% sodium chloride and 0.4% ammonium acetate as buffers; 0.01% edetate disodium; 1% benzyl alcohol as preservative in water for injection and pH adjusted to 6.8 to 7.8 with sodium hydroxide.

Chemically, bumetanide is 3-(butylamino)-4-phenoxy-5-sulfamoylbenzoic acid. It is a practically white or almost white, crystalline powder having a calculated molecular weight of 364.42, and the following structural formula:

Bumetanide – Clinical Pharmacology

Bumetanide is a loop diuretic with a rapid onset and short duration of action. Pharmacological and clinical studies have shown that 1 mg bumetanide has a diuretic potency equivalent to approximately 40 mg furosemide. The major site of bumetanide action is the ascending limb of the loop of Henle.

The mode of action has been determined through various clearance studies in both humans and experimental animals. Bumetanide inhibits sodium reabsorption in the ascending limb of the loop of Henle, as shown by marked reduction of free-water clearance (CH2O) during hydration and tubular free-water reabsorption (TcH2O) during hydropenia. Reabsorption of chloride in the ascending limb is also blocked by bumetanide, and bumetanide is somewhat more chloruretic than natriuretic.

Potassium excretion is also increased by bumetanide, in a dose-related fashion.

Bumetanide may have an additional action in the proximal tubule. Since phosphate reabsorption takes place largely in the proximal tubule, phosphaturia during bumetanide induced diuresis is indicative of this additional action. This is further supported by the reduction in the renal clearance of bumetanide by probenecid, associated with diminution in the natriuretic response. This proximal tubular activity does not seem to be related to an inhibition of carbonic anhydrase. Bumetanide does not appear to have a noticeable action on the distal tubule.

Bumetanide decreases uric acid excretion and increases serum uric acid. Diuresis starts within minutes following an intravenous injection and reaches maximum levels within 15 to 30 minutes.

Several pharmacokinetic studies have shown that bumetanide, administered orally or parenterally, is eliminated rapidly in humans, with a half-life of between 1 and 1½ hours. Plasma protein-binding is in the range of 94% to 96%.

Oral administration of carbon-14 labeled bumetanide to human volunteers revealed that 81% of the administered radioactivity was excreted in the urine, 45% of it as unchanged drug. Urinary and biliary metabolites identified in this study were formed by oxidation of the N-butyl side chain. Biliary excretion of bumetanide amounted to only 2% of the administered dose.

Pediatric Pharmacology

Elimination of bumetanide appears to be considerably slower in neonatal patients compared with adults, possibly because of immature renal and hepatobiliary function in this population. Small pharmacokinetic studies of intravenous bumetanide in preterm and full-term neonates with respiratory disorders have reported an apparent half-life of approximately 6 hours, with a range up to 15 hours and a serum clearance ranging from 0.2 to 1.1 mL/min/kg. In a population of neonates receiving bumetanide for volume overload, mean serum clearance rates were 2.17 mL/min/kg in patients less than 2 months of age and 3.8 mL/min/kg in patients aged 2 to 6 months. Mean serum half-life of bumetanide was 2.5 hours and 1.5 hours in patients aged less than 2 months and those aged 2 to 6 months, respectively. Elimination half-life decreased considerably during the first month of life, from a mean of approximately 6 hours at birth to approximately 2.4 hours at 1 month of age.

In preterm neonates, mean serum concentrations following a single 0.05 mg/kg dose ranged from 126 mcg/L at 1 hour to 57 mcg/L at 8 hours. In another study, mean serum concentrations following a single 0.05 mg/kg dose were 338 ng/mL at 30 minutes and 176 ng/mL after 4 hours. A single dose of 0.1 mg/kg produced mean serum levels of 314 ng/mL at 1 hour, and 195 ng/mL at 6 hours. Mean volume of distribution in neonates and infants has been reported to range from 0.26 L/kg to 0.39 L/kg.

The degree of protein binding of bumetanide in cord sera from healthy neonates was approximately 97%, suggesting the potential for bilirubin displacement. A study using pooled sera from critically ill neonates found that bumetanide at concentrations of 0.5 to 50 mcg/mL, but not 0.25 mcg/mL, caused a linear increase in unbound bilirubin concentrations.

In 56 infants aged 4 days to 6 months, bumetanide doses ranging from 0.005 mg/kg to 0.1 mg/kg were studied for pharmacodynamic effect. Peak bumetanide excretion rates increased linearly with increasing doses of drug. Maximal diuretic effect was observed at a bumetanide excretion rate of about 7 mcg/kg/hr, corresponding to doses of 0.035 to 0.040 mg/kg. Higher doses produced a higher bumetanide excretion rate but no increase in diuretic effect. Urine flow rate peaked during the first hour after drug administration in 80% of patients and by 3 hours in all patients.

Geriatric Pharmacology

In a group of ten geriatric subjects between the ages of 65 and 73 years, total bumetanide clearance was significantly lower (1.8 ± 0.3 mL/min/kg) compared with younger subjects

(2.9 ± 0.2 mL/min/kg) after a single oral bumetanide 0.5 mg dose. Maximum plasma concentrations were higher in geriatric subjects (16.9 ± 1.8 ng/mL) compared with younger subjects (10.3 ± 1.5 ng/mL). Urine flow rate and total excretion of sodium and potassium were increased less in the geriatric subjects compared with younger subjects, although potassium excretion and fractional sodium excretion were similar between the two age groups. Nonrenal clearance, bioavailability, and volume of distribution were not significantly different between the two groups.

Indications and Usage for Bumetanide

Bumetanide injection, USP is indicated for the treatment of edema associated with congestive heart failure, hepatic and renal disease, including the nephrotic syndrome.

Almost equal diuretic response occurs after oral and parenteral administration of bumetanide. Therefore, if impaired gastrointestinal absorption is suspected or oral administration is not practical, bumetanide should be given by the intramuscular or intravenous route.

Successful treatment with bumetanide injection, USP following instances of allergic reactions to furosemide suggests a lack of cross-sensitivity.

Contraindications

Bumetanide is contraindicated in anuria. Although bumetanide can be used to induce diuresis in renal insufficiency, any marked increase in blood urea nitrogen or creatinine, or the development of oliguria during therapy of patients with progressive renal disease, is an indication for discontinuation of treatment with bumetanide. Bumetanide is also contraindicated in patients in hepatic coma or in states of severe electrolyte depletion until the condition is improved or corrected. Bumetanide is contraindicated in patients hypersensitive to this drug.

Warnings

Volume and Electrolyte Depletion

The dose of bumetanide should be adjusted to the patient’s need. Excessive doses or too frequent administration can lead to profound water loss, electrolyte depletion, dehydration, reduction in blood volume and circulatory collapse with the possibility of vascular thrombosis and embolism, particularly in elderly patients.

Hypokalemia

Hypokalemia can occur as a consequence of bumetanide administration. Prevention of hypokalemia requires particular attention in the following conditions: patients receiving digitalis and diuretics for congestive heart failure, hepatic cirrhosis and ascites, states of aldosterone excess with normal renal function, potassium-losing nephropathy, certain diarrheal states, or other states where hypokalemia is thought to represent particular added risks to the patient, i.e., history of ventricular arrhythmias.

In patients with hepatic cirrhosis and ascites, sudden alterations of electrolyte balance may precipitate hepatic encephalopathy and coma. Treatment in such patients is best initiated in the hospital with small doses and careful monitoring of the patient’s clinical status and electrolyte balance. Supplemental potassium and/or spironolactone may prevent hypokalemia and metabolic alkalosis in these patients.

Ototoxicity

In cats, dogs and guinea pigs, bumetanide has been shown to produce ototoxicity. In these test animals, bumetanide was 5 to 6 times more potent than furosemide and, since the diuretic potency of bumetanide is about 40 to 60 times furosemide, it is anticipated that blood levels necessary to produce ototoxicity will rarely be achieved. The potential exists, however, and must be considered a risk of intravenous therapy, especially at high doses, repeated frequently in the face of renal excretory function impairment. Potentiation of aminoglycoside ototoxicity has not been tested for bumetanide. Like other members of this class of diuretics, bumetanide probably shares this risk.

Allergy to Sulfonamides

Patients allergic to sulfonamides may show hypersensitivity to bumetanide.

Thrombocytopenia

Since there have been rare spontaneous reports of thrombocytopenia from postmarketing experience, patients should be observed regularly for possible occurrence of thrombocytopenia.

Precautions

General

Serum potassium should be measured periodically and potassium supplements or potassium-sparing diuretics added if necessary. Periodic determinations of other electrolytes are advised in patients treated with high doses or for prolonged periods, particularly in those on low-salt diets.

Hyperuricemia may occur; it has been asymptomatic in cases reported to date. Reversible elevations of the BUN and creatinine may also occur, especially in association with dehydration and particularly in patients with renal insufficiency. Bumetanide may increase urinary calcium excretion with resultant hypocalcemia.

Diuretics have been shown to increase the urinary excretion of magnesium; this may result in hypomagnesemia.

Laboratory Tests

Studies in normal subjects receiving bumetanide revealed no adverse effects on glucose tolerance, plasma insulin, glucagon and growth hormone levels, but the possibility of an effect on glucose metabolism exists. Periodic determinations of blood sugar should be done, particularly in patients with diabetes or suspected latent diabetes.

Patients under treatment should be observed regularly for possible occurrence of blood dyscrasias, liver damage or idiosyncratic reactions, which have been reported occasionally in foreign marketing experience. The relationship of these occurrences to bumetanide use is not certain.

Drug Interactions

Drugs with Ototoxic Potential

Especially in the presence of impaired renal function, the use of parenterally administered bumetanide in patients to whom aminoglycoside antibiotics are also being given should be avoided, except in life-threatening conditions.

Drugs with Nephrotoxic Potential

There has been no experience with the concurrent use of bumetanide with drugs known to have a nephrotoxic potential. Therefore, the simultaneous administration of these drugs should be avoided.

Lithium

Lithium should generally not be given with diuretics (such as bumetanide) because they reduce its renal clearance and add a high risk of lithium toxicity.

Probenecid

Pretreatment with probenecid reduces both the natriuresis and hyperreninemia produced by bumetanide. This antagonistic effect of probenecid on bumetanide natriuresis is not due to a direct action on sodium excretion but is probably secondary to its inhibitory effect on renal tubular secretion of bumetanide. Thus, probenecid should not be administered concurrently with bumetanide.

Indomethacin

Indomethacin blunts the increases in urine volume and sodium excretion seen during bumetanide treatment and inhibits the bumetanide-induced increase in plasma renin activity. Concurrent therapy with bumetanide is thus not recommended.

Antihypertensives

Bumetanide may potentiate the effect of various antihypertensive drugs, necessitating a reduction in the dosage of these drugs.

Digoxin

Interaction studies in humans have shown no effect on digoxin blood levels.

Anticoagulants

Interaction studies in humans have shown bumetanide to have no effect on warfarin metabolism or on plasma prothrombin activity.

Carcinogenesis, Mutagenesis and Impairment of Fertility

Bumetanide was devoid of mutagenic activity in various strains of Salmonella typhimurium when tested in the presence or absence of an in vitro metabolic activation system. An 18-month study showed an increase in mammary adenomas of questionable significance in female rats receiving oral doses of 60 mg/kg/day (2000 times a 2-mg human dose). A repeat study at the same doses failed to duplicate this finding.

Reproduction studies were performed to evaluate general reproductive performance and fertility in rats at oral dose levels of 10, 30, 60 or 100 mg/kg/day. The pregnancy rate was slightly decreased in the treated animals; however, the differences were small and not statistically significant.

Pregnancy

Teratogenic Effects

Bumetanide is neither teratogenic nor embryocidal in mice when given in doses up to 3400 times the maximum human therapeutic dose.

Bumetanide has been shown to be nonteratogenic, but it has a slight embryocidal effect in rats when given in doses of 3400 times the maximum human therapeutic dose and in rabbits at doses of 3.4 times the maximum human therapeutic dose. In one study, moderate growth retardation and increased incidence of delayed ossification of sternebrae were observed in rats at oral doses of 100 mg/kg/day, 3400 times the maximum human therapeutic dose. These effects were associated with maternal weight reductions noted during dosing. No such adverse effects were observed at 30 mg/kg/day (1000 times the maximum human therapeutic dose). No fetotoxicity was observed at 1000 to 2000 times the human therapeutic dose.

In rabbits, a dose-related decrease in litter size and an increase in resorption rate were noted at oral doses of 0.1 and 0.3 mg/kg/day (3.4 and 10 times the maximum human therapeutic dose). A slightly increased incidence of delayed ossification of sternebrae occurred at 0.3 mg/kg/day; however, no such adverse effects were observed at the dose of 0.03 mg/kg/day. The sensitivity of the rabbit to bumetanide parallels the marked pharmacologic and toxicologic effects of the drug in this species.

Bumetanide was not teratogenic in the hamster at an oral dose of 0.5 mg/kg/day (17 times the maximum human therapeutic dose). Bumetanide was not teratogenic when given intravenously to mice and rats at doses up to 140 times the maximum human therapeutic dose.

There are no adequate and well-controlled studies in pregnant women. A small investigational experience in the United States and marketing experience in other countries to date have not indicated any evidence of adverse effects on the fetus, but these data do not rule out the possibility of harmful effects. Bumetanide should be given to a pregnant woman only if the potential benefit justifies the potential risk to the fetus.

Nursing Mothers

It is not known whether this drug is excreted in human milk. As a general rule, nursing should not be undertaken while the patient is on bumetanide since it may be excreted in human milk.

Pediatric Use

Safety and effectiveness in pediatric patients below the age of 18 have not been established.

In vitro studies using pooled sera from critically ill neonates have shown bumetanide to be a potent displacer of bilirubin [see Clinical Pharmacology: Pediatric Pharmacology]. The administration of bumetanide could present a particular concern if given to critically ill or jaundiced neonates at risk for kernicterus.

Geriatric Use

Clinical studies of bumetanide did not include sufficient numbers of subjects aged 65 and over to determine whether they responded differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.

This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

Adverse Reactions/Side Effects

The most frequent clinical adverse reactions considered probably or possibly related to bumetanide are muscle cramps (seen in 1.1% of treated patients), dizziness (1.1%), hypotension (0.8%), headache (0.6%), nausea (0.6%) and encephalopathy (in patients with preexisting liver disease) (0.6%). One or more of these adverse reactions have been reported in approximately 4.1% of patients treated with bumetanide.

Less frequent clinical adverse reactions to bumetanide are impaired hearing (0.5%), pruritus (0.4%), electrocardiogram changes (0.4%), weakness (0.2%), hives (0.2%), abdominal pain (0.2%), arthritic pain (0.2%), musculoskeletal pain (0.2%), rash (0.2%) and vomiting (0.2%). One or more of these adverse reactions have been reported in approximately 2.9% of patients treated with bumetanide.

Other clinical adverse reactions, which have each occurred in approximately 0.1% of patients, are vertigo, chest pain, ear discomfort, fatigue, dehydration, sweating, hyperventilation, dry mouth, upset stomach, renal failure, asterixis, itching, nipple tenderness, diarrhea, premature ejaculation and difficulty maintaining an erection.

Laboratory abnormalities reported have included hyperuricemia (in 18.4% of patients tested), hypochloremia (14.9%), hypokalemia (14.7%), azotemia (10.6%), hyponatremia (9.2%), increased serum creatinine (7.4%), hyperglycemia (6.6%), and variations in phosphorus (4.5%), CO2 content (4.3%), bicarbonate (3.1%) and calcium (2.4%). Although manifestations of the pharmacologic action of bumetanide, these conditions may become more pronounced by intensive therapy.

Also reported have been thrombocytopenia (0.2%) and deviations in hemoglobin (0.8%), prothrombin time (0.8%), hematocrit (0.6%), WBC (0.3%) and differential counts (0.1%). There have been rare spontaneous reports of thrombocytopenia from postmarketing experience.

Diuresis induced by bumetanide may also rarely be accompanied by changes in LDH (1.0%), total serum bilirubin (0.8%), serum proteins (0.7%), SGOT (0.6%), SGPT (0.5%), alkaline phosphatase (0.4%), cholesterol (0.4%) and creatinine clearance (0.3%). Increases in urinary glucose (0.7%) and urinary protein (0.3%) have also been seen.

Overdosage

Overdosage can lead to acute profound water loss, volume and electrolyte depletion, dehydration, reduction of blood volume and circulatory collapse with a possibility of vascular thrombosis and embolism. Electrolyte depletion may be manifested by weakness, dizziness, mental confusion, anorexia, lethargy, vomiting and cramps. Treatment consists of replacement of fluid and electrolyte losses by careful monitoring of the urine and electrolyte output and serum electrolyte levels.

Bumetanide Dosage and Administration

Dosage should be individualized with careful monitoring of patient response.

Parenteral Administration

Bumetanide Injection may be administered parenterally (IV or IM) to patients in whom gastrointestinal absorption may be impaired or in whom oral administration is not practical.

Parenteral treatment should be terminated and oral treatment instituted as soon as possible.

The usual initial dose is 0.5 mg to 1 mg intravenously or intramuscularly. Intravenous administration should be given over a period of 1 to 2 minutes. If the response to an initial dose is deemed insufficient, a second or third dose may be given at intervals of 2 to 3 hours, but should not exceed a daily dosage of 10 mg.

Miscibility and Parenteral Solutions

The compatibility tests of bumetanide injection with 5% dextrose in water, 0.9% sodium chloride and lactated Ringer’s solution in both glass and plasticized PVC (Viaflex) containers have shown no significant absorption effect with either containers, nor a measurable loss of potency due to degradation of the drug. However, solutions should be freshly prepared and used within 24 hours.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.

Budesonide, glycopyrrolate, and formoterol inhaler https://drugonomy.com/2026/02/09/budesonide-glycopyrrolate-and-formoterol-inhaler/ https://drugonomy.com/2026/02/09/budesonide-glycopyrrolate-and-formoterol-inhaler/#respond Mon, 09 Feb 2026 21:23:25 +0000 https://drugonomy.com/?p=11254 What is a budesonide, glycopyrrolate, and formoterol inhaler?

A budesonide, glycopyrrolate, and formoterol inhaler (Breztri Aerosphere) combines 3 medicines into 1 inhaler and is used as a long-term treatment for COPD (chronic obstructive pulmonary disease) in adults. The 3 medicines are:

  • an inhaled corticosteroid (ICS) medicine (budesonide)
  • an anticholinergic medicine (glycopyrrolate)
  • a long-acting beta2-adrenergic agonist (LABA) medicine (formoterol).

Budesonide, glycopyrrolate, and formoterol gained FDA approval under the brand name Breztri Aerosphere on July 23, 2020. There is no generic.

How do budesonide, glycopyrrolate, and formoterol work together?

The 3 ingredients in a budesonide, glycopyrrolate, and formoterol inhaler have different mechanisms of action and work together to help control COPD symptoms.

  • Budesonide decreases lung inflammation, which can lead to breathing problems.
  • Glycopyrrolate blocks the neurotransmitter acetylcholine in the lungs, allowing the airways to relax and widen, making breathing easier.
  • Formoterol activates beta2-adrenergic receptors on the smooth muscle cells in the airways, allowing the airways to widen, making breathing easier. Formoterol has a long-lasting effect, typically lasting 12 hours or more, which provides sustained symptom relief throughout the day for COPD patients.

Clinical trials have not been done using a budesonide, glycopyrrolate, and formoterol for asthma, and this inhaler is not approved for asthma, only for COPD. 

This inhaler should not be used to relieve sudden breathing problems and will not replace a rescue inhaler, such as albuterol. If you do not have a rescue inhaler, talk to your healthcare provider.

Budesonide, glycopyrrolate, and formoterol side effects

The most common side effects of a budesonide, glycopyrrolate, and formoterol inhaler are:

  • upper respiratory tract infections (such as sinusitis) or the flu
  • lung infections (such as pneumonia)
  • back pain
  • oral thrush. Wash your mouth out with water and spit out after using the inhaler to help prevent this
  • joint pain or muscle spasms
  • headache
  • high blood sugar levels
  • a cough or hoarseness
  • gastrointestinal effects such as diarrhea or nausea
  • signs of a urinary tract infection including painful and frequent urination
  • difficulty sleeping
  • feeling anxious
  • heart palpitations.

Tell your healthcare provider about any side effect that bothers you or does not go away.

Serious side effects and warnings

A budesonide, glycopyrrolate, and formoterol inhaler can cause the following serious side effects.

Fungal infections in your mouth or throat (thrush). Rinse your mouth with water without swallowing after using your budesonide, glycopyrrolate, and formoterol inhaler to help reduce your chance of getting thrush.

Pneumonia. People with COPD have a higher chance of getting pneumonia. Budesonide, glycopyrrolate, and formoterol Aerosphere may increase your chance of getting pneumonia. Call your healthcare provider if you notice any of the following symptoms:

  • an increase in sputum production
  • change in the color of your mucus
  • fever
  • chills
  • increased cough
  • increased breathing problems.

A weakened immune system and an increased chance of getting infections (immunosuppression). Budesonide, glycopyrrolate, and formoterol may make it harder for your immune system to fight infections.

Reduced adrenal function (adrenal insufficiency). Adrenal insufficiency is a condition where the adrenal glands do not make enough steroid hormones. This can happen when you stop taking oral corticosteroid medicines (such as prednisone) and start taking a medicine containing an ICS (such as budesonide, glycopyrrolate, and formoterol inhaler). During this transition period, when your body is under stress from fever, trauma (such as a car accident), infection, surgery, or worse COPD symptoms, adrenal insufficiency can get worse and may cause death.
Symptoms of adrenal insufficiency include:

  • feeling tired
  • lack of energy
  • weakness
  • nausea and vomiting
  • low blood pressure (hypotension).

Sudden breathing problems immediately after inhaling your medicine. If you have sudden breathing problems immediately after using your budesonide, glycopyrrolate, and formoterol inhaler, stop using it and call your healthcare provider right away.

Serious allergic reactions. Call your healthcare provider or get emergency medical care if you get any of the following symptoms of a serious allergic reaction after using your budesonide, glycopyrrolate, and formoterol inhaler:

  • rash
  • hives
  • swelling of your face, mouth, and tongue
  • breathing problems.

Budesonide, glycopyrrolate, and formoterol may affect your heart. Tell your healthcare provider immediately if your blood pressure increases or you develop a fast or irregular heartbeat or chest pain after using this inhaler.

Budesonide, glycopyrrolate, and formoterol may affect your nervous system. Tell your healthcare provider immediately if you develop a tremor or if you find yourself more anxious or nervous after using this inhaler.

Bone thinning or weakness (osteoporosis). Budesonide, glycopyrrolate, and formoterol may reduce your bone density and cause thinning or weakness.

Budesonide, glycopyrrolate, and formoterol may cause new or worsened eye problems including acute narrow-angle glaucoma and cataracts. Acute narrow-angle glaucoma can cause permanent loss of vision if not treated. Symptoms of acute narrow-angle glaucoma may include:

  • eye pain or discomfort
  • nausea or vomiting
  • blurred vision
  • seeing halos or bright colors around lights
  • red eyes.

If you have these symptoms, call your healthcare provider right away before taking another dose.

Urinary retention. People who take budesonide, glycopyrrolate, and formoterol inhaler may develop new or worsening urinary retention. Symptoms of urinary retention may include:

    • difficulty urinating
    • urinating frequently
    • painful urination
    • urination in a weak stream or drips

If you have these symptoms of urinary retention, stop taking budesonide, glycopyrrolate, and formoterol Aerosphere and call your healthcare provider right away before taking another dose.

Changes in laboratory blood values, including high levels of blood sugar (hyperglycemia) and low levels of potassium (hypokalemia) have been reported after using a Budesonide, glycopyrrolate, and formoterol inhaler. Low levels of potassium may cause symptoms of muscle spasm, muscle weakness, or abnormal heart rhythm.

These are not all the possible side effects of budesonide, glycopyrrolate, and formoterol. Ask your healthcare provider or pharmacist for more information. Call your doctor for medical advice about side effects.

How should I use budesonide, glycopyrrolate, and formoterol inhaler?

A budesonide, glycopyrrolate, and formoterol inhaler is used as 2 puffs in the morning and 2 puffs in the evening.

  • to improve symptoms of COPD for better breathing and to reduce the number of flare-ups (the worsening of your COPD symptoms for several days).

  • Before using budesonide, glycopyrrolate, and formoterol inhaler, make sure your healthcare provider has taught you how to use the inhaler and that you understand how to use it correctly.
  • Use this medicine exactly as your healthcare provider tells you to use it. Do not use it more often than prescribed.
  • Use 2 inhalations of budesonide, glycopyrrolate, and formoterol inhaler, 2 times each day (2 puffs in the morning and 2 puffs in the evening).
  • Do not take more than 2 inhalations of this inhaler 2 times each day.
  • If a dose (2 puffs) is missed, it should be taken as soon as possible and the next dose should be taken at the usual time. Do not take more than one dose to make up for a forgotten dose.
  • Rinse your mouth with water and spit the water out after each dose (2 puffs). Do not swallow the water. This will help to reduce the chance of getting a fungus infection (thrush) in the mouth and throat.
  • If you take too much budesonide, glycopyrrolate, and formoterol inhaler, call your healthcare provider or go to the nearest hospital emergency room right away if you have any unusual symptoms, such as worsening shortness of breath, chest pain, increased heart rate, or shakiness.
  • Do not spray the budesonide, glycopyrrolate, and formoterol inhaler into your eyes. If it gets in your eyes, rinse them well with water. If redness continues, call your healthcare provider.
  • Do not use other medicines that contain a LABA or an anticholinergic for any reason. Ask your healthcare provider or pharmacist if any of your other medicines are LABA or anticholinergic-containing medicines.
  • Do not change or stop any medicines used to control or treat your breathing problems. Your healthcare provider will change your medicines as needed.
  • A budesonide, glycopyrrolate, and formoterol inhaler will not relieve sudden breathing problems and you should not take extra doses to relieve sudden symptoms. Always have a rescue inhaler with you to treat sudden symptoms. If you do not have a rescue inhaler, call your healthcare provider to have one prescribed for you.
  • Call your healthcare provider or get emergency medical care right away if:
    • your breathing problems get worse.
    • you need to use your rescue inhaler more often than usual.
    • your rescue inhaler does not work as well to relieve your symptoms.

What other drugs will affect budesonide, glycopyrrolate, and formoterol?

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Budesonide, glycopyrrolate, and formoterol inhaler and certain other medicines may interact with each other. This may cause serious side effects.

Especially tell your healthcare provider if you take:

  • anticholinergics (including tiotropium, ipratropium, aclidinium, and umeclidinium)
  • other LABAs (including salmeterol, formoterol, arformoterol tartrate, vilanterol, olodaterol, and indacaterol)
  • atropine
  • antifungal or anti-HIV medicines.

Budesonide, glycopyrrolate, and formoterol should not be used with other combination inhalers, such as Trelegy . Budesonide, glycopyrrolate, and formoterol may be used with rescue inhalers, such as albuterol.

Budesonide and formoterol (Inhalation) https://drugonomy.com/2026/02/09/budesonide-and-formoterol-inhalation/ https://drugonomy.com/2026/02/09/budesonide-and-formoterol-inhalation/#respond Mon, 09 Feb 2026 21:16:01 +0000 https://drugonomy.com/?p=11251 Uses for budesonide and formoterol

Budesonide and formoterol combination is used to help control the symptoms of asthma and improve lung function. It is used when a patient’s asthma has not been controlled sufficiently on other asthma medicines, or when a patient’s condition is so severe that more than one medicine is needed every day.

Budesonide and formoterol combination is also used as long-term maintenance treatment of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. This medicine helps improve and reduce the number of flare-ups of the symptoms of COPD.

Inhaled budesonide belongs to the family of medicines known as corticosteroids (cortisone-like medicines). It works by preventing inflammation (swelling) in the lungs that causes an asthma attack.

Formoterol belongs to the family of medicines known as long-acting bronchodilators. Bronchodilators are medicines that are breathed in through the mouth to open up the bronchial tubes (air passages) in the lungs. They relieve cough, wheezing, and trouble breathing by increasing the flow of air through the bronchial tubes.

This medicine is available only with your doctor’s prescription.

Proper use of budesonide and formoterol

Use this medicine only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered. Do not stop using this medicine without telling your doctor. To do so may make your condition worse.

Inhaled fluticasone and salmeterol is used to prevent asthma attacks and treat chronic obstructive pulmonary disease (COPD). It is not used to relieve an asthma attack that has already started. For relief of an asthma attack that has already started, you should use another medicine. If you do not have another medicine to use for an attack or if you have any questions about this, check with your doctor.

This medicine comes with a patient information leaflet or patient instructions. Read the directions carefully before using this medicine. If you do not understand the directions or you are not sure how to use the inhaler, ask your doctor or pharmacist to show you what to do. Also, ask your doctor to check regularly how you use the inhaler to make sure you are using it properly.

In order for this medicine to help prevent asthma attacks, it must be used every day in regularly spaced doses, as ordered by your doctor.

When you use the Symbicort® inhaler for the first time, or if you have not used it for 7 days or longer, or if the inhaler has been dropped, it may not deliver the right amount of medicine with the first inhalation. Therefore, before using the inhaler, prime it by spraying the medicine 2 times into the air away from the face, and shaking it well for 5 seconds before each spray.

To use the Symbicort® inhaler:

  • Take the inhaler out of the moisture-protective foil pouch before you use it for the first time.
  • Do not use the inhaler for this medicine with any other medicine.
  • Prime the inhaler before use by shaking the inhaler well for 5 seconds and then releasing a test spray. Once again, shake the inhaler and release a second test spray.
  • Breathe out to the end of a normal breath (exhale). Do not breathe into the inhaler.
  • Put the mouthpiece fully into your mouth and close your lips around it. Do not block the mouthpiece with your teeth or tongue.
  • While pressing down firmly and fully on the grey top of the inhaler, breathe in through your mouth as deeply as you can until you have taken a full deep breath.
  • Hold your breath and remove the mouthpiece from your mouth. Continue holding your breath for as long as you can up to 10 seconds before breathing out slowly. This gives the medicine time to settle in your airways and lungs.
  • Release your finger from the grey top and then turn your head away from the inhaler. Breathe out slowly to the end of a normal breath. Do not breathe into the inhaler.
  • Shake the inhaler again for 5 seconds and take the second inhalation following exactly the same steps you used for the first inhalation.
  • Replace the mouthpiece cover after using the medicine.
  • Gargle and rinse your mouth with water after each dose. This will help prevent hoarseness, throat irritation, and infection in the mouth. Do not swallow the water after rinsing.
  • Clean the inhaler every 7 days by wiping the mouthpiece with a dry cloth. Do not put the inhaler into water or try to take it apart. However, you must use a new inhaler with each refill of your medicine.

The dose counter at the top of the Symbicort® inhaler will turn yellow when the inhaler has 20 or fewer doses left. Throw the inhaler when it reaches 0, or if it has been 3 months since you last opened the foil pouch.

When you use the Symbicort Aerosphere® inhaler for the first time, it may not deliver the right amount of medicine with the first puff. Therefore, before using the inhaler, prime it by spraying the medicine 4 times into the air away from the face, and shaking it well before each spray. If you have not used it for 7 days or longer or if you’ve dropped it, re-prime by spraying the medicine 2 times into the air away from the face, and shaking it well before each spray.

To use the Symbicort Aerosphere® inhaler:

  • This medicine comes in a sealed foil pouch. Do not open the foil pouch until you are ready to use a dose of this medicine.
  • Once opened, remove the inhaler from the pouch.
  • Take the cap off the mouthpiece. Check the mouthpiece to make sure it is clear.
  • Press the center of the dose indicator all the way down and release it. You may hear a soft click from the dose indicator as it counts down during use.
  • To inhale this medicine, breathe out fully and try to get as much air out of your lungs as possible. Put your lips tightly around the mouthpiece and breathe in quickly and deeply until the canister stops moving in the actuator and a puff of medicine has been released.
  • Remove the inhaler from your mouth and hold your breath for as long as is comfortable, and then breathe out slowly through your nose.
  • Rinse your mouth with water after each dose. This will help prevent infection in the mouth. Do not swallow the water after rinsing.
  • Clean the actuator at least once a week with warm water for 30 seconds. Shake off the excess water. Let the actuator air-dry overnight. Do not let the canister get wet.

Budesonide (oral) https://drugonomy.com/2026/02/09/budesonide-oral/ https://drugonomy.com/2026/02/09/budesonide-oral/#respond Mon, 09 Feb 2026 21:09:16 +0000 https://drugonomy.com/?p=11248 What is budesonide?

Oral budesonide is used to treat the following conditions with inflammation as a symptom:

  • Eosinophilic esophagitis (EoE) in adults and children 11 years and older for up to 12 weeks (Eohilia [budesonide oral suspension 2 mg/10 mL])
  • Active, mild to moderate Crohn’s disease (CD) that involves the ileum and/or ascending colon in adults and children 8 years and older who weigh at least 55 pounds (25 kg). Also used in adults for up to 3 months to maintain clinical remission in CD (Entocort EC, generic, and Ortikos [budesonide extended-release capsules 3 mg, 6 mg, 9 mg])
  • Active, mild to moderate ulcerative colitis in adults, to help induce remission (Uceris and generic [budesonide extended-release tablets 9 mg])
  • Primary immunoglobulin A nephropathy (IgAN) to reduce the loss of kidney function in those who are at risk for disease progression (Tarpeyo [budesonide delayed release capsules 4 mg])

Budesonide works by preventing the activation of inflammatory cells (such as mast cells, eosinophils, and neutrophils) and blocking inflammatory mediators such as histamine and cytokines, which are involved in allergic responses. Exactly how it works for EoE is not fully understood, but inflammation plays a key role in EoE development. It belongs to the drug class called corticosteroids.

Budesonide is a potent anti-inflammatory corticosteroid, 200 times stronger than cortisol and 15 times stronger than prednisolone. It has high glucocorticoid effects (strong effects on inflammation, immune system, wound healing, and intermediary metabolism) and weak mineralocorticoid effects (less effects on water, salt, and mineral metabolism).

Budesonide oral FDA approvals are as follows:

  • Eohilia (budesonide oral suspension 2 mg/10 mL; February 9, 2024). No generic.
  • Entocort EC (budesonide extended-release capsule 3 mg; October 2, 2001). Generic available.
  • Ortikos (budesonide extended-release capsule 6 mg, 9 mg; June 13, 2019 [discontinued]).  
  • Uceris (budesonide extended-release tablet 9 mg; January 14, 2013). Generic available.
  • Tarpeyo (budesonide delayed-release capsule 4 mg; December 15, 2021). No generic.

Serious side effects and warnings

Budesonide (oral) may cause the following serious side effects:

  • Effects of having too much corticosteroid medicine in your blood (hypercorticism). Long-term use of budesonide may cause you to have elevated levels of corticosteroid medicine in your blood. Tell your healthcare provider if you have any of the following signs and symptoms:
    • acne
    • thicker body hair and facial hair
    • bruise easily
    • a fatty pad or hump between your shoulders (buffalo hump)
    • rounding of your face
    • pink or purple stretch marks on the skin of your abdomen, thighs, breasts, and arms
    • ankle swelling.
  • Adrenal suppression. Long-term use of budesonide can cause a condition in which the adrenal glands do not make enough steroid hormones (adrenal suppression). Tell your healthcare provider if you are under stress or if you have any of the following signs or symptoms:
    • tiredness
    • nausea and vomiting
    • weakness
    • low blood pressure.
  • Decreased ability of your body to fight infections (immunosuppression) and increased risk of infection. Corticosteroid medicines, including budesonide, lower the ability of your immune system to fight infections and increase the risk of infections caused by viruses, bacteria, fungi, protozoans, or certain parasites. Corticosteroid medicines, including budesonide, can also:
    • make current infections worse
    • increase the risk of infections spreading (disseminated)
    • increase the risk of making infections active again or making infections worse that have not been active (latent)
    • hide (mask) some signs of infection

These infections can be mild, but can also be severe and lead to death. Your healthcare provider should check you closely for signs and symptoms of an infection while taking budesonide. Tell your healthcare provider right away about any signs or symptoms of a new or worsening infection while taking budesonide, including flu-like symptoms such as:

    • fever
    • cough
    • chills
    • pain
    • stomach area (abdominal) pain
    • feeling tired
    • aches 
    • nausea and vomiting
    • diarrhea.
  • Tuberculosis: If you have inactive (latent) tuberculosis, your tuberculosis may become active again while taking budesonide. Your healthcare provider should check you closely for signs and symptoms of tuberculosis while taking budesonide.
  • Chicken pox and measles: People taking corticosteroid medicines, including budesonide, who have not had chicken pox or measles, should avoid contact with people who have these diseases. Tell your healthcare provider right away if you come in contact with anyone who has chicken pox or measles.
  • Hepatitis B virus (HBV) reactivation: If you are a carrier of HBV, the virus can become an active infection again while taking budesonide. Your healthcare provider will test you for HBV before you start taking budesonide.
  • Amebiasis: Inactive (latent) amebiasis may become an active infection while taking budesonide. Your healthcare provider should check you for amebiasis before you start taking budesonide if you have spent time in the tropics or have unexplained symptoms.
  • Fungal infections of the mouth (thrush), throat, and esophagus in patients using budesonide may occur. Symptoms of infection include
    • white spots in the mouth, a burning or painful sensation in your mouth, redness inside of your mouth, difficulty with eating or
    • swallowing, loss of taste, and a feeling like cotton is in your mouth. Tell your healthcare provider if any of the above symptoms occur.
  • Erosive esophagitis. Budesonide can cause acid-related damage to the lining of the esophagus. Tell your healthcare provider if you notice any new or worsening signs or symptoms such as:
    • heartburn
    • chest pain
    • trouble swallowing.
  • Effect on growth. Taking corticosteroids can affect your child’s growth. Tell your healthcare provider if you are worried about your child’s growth. Your healthcare provider may monitor the growth of your child while taking budesonide.
  • Worsening of allergies. If you take certain other corticosteroid medicines to treat allergies, switching to budesonide may cause your allergies to come back. These allergies may include a skin condition called eczema or inflammation inside your nose (rhinitis). Tell your healthcare provider if any of your allergies become worse while taking budesonide.
  • Kaposi’s sarcoma: Kaposi’s sarcoma has happened in people who receive corticosteroid therapy, most often for treatment of long-lasting (chronic) conditions.

Get emergency medical help if you have signs of an allergic reaction: hives, difficulty breathing, swelling of your face, lips, tongue, or throat.

This is not a complete list of side effects, and others may occur. Call your doctor for medical advice about side effects.

Bryhali https://drugonomy.com/2026/02/09/bryhali/ https://drugonomy.com/2026/02/09/bryhali/#respond Mon, 09 Feb 2026 21:01:49 +0000 https://drugonomy.com/?p=11245 What is Bryhali?

Bryhali is a high-potency, Class I corticosteroid lotion that may be used by adults to reduce inflammation and itching caused by plaque psoriasis. It contains 0.01% halobetasol propionate.

Bryhali was approved on November 6, 2018. It contains a lower concentration than other halobetasol propionate lotions which limits its risk of side effects.

Warnings

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Bryhali (halobetasol propionate 0.01% lotion) is a highly potent, Class I corticosteroid that can be absorbed through the skin into the bloodstream and cause reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for glucocorticosteroid insufficiency, including Cushing’s syndrome, hyperglycemia, and glucosuria. Do not use for longer than 2 weeks and do not exceed the recommended dose. Periodic monitoring for HPA suppression may be required.

Before taking this medicine

You should not use halobetasol topical if you are allergic to it.

Bryhali should not be applied to lesions that are exuding serum or to skin folds (where two areas of skin touch each other).

Tell your doctor if you have ever had:

  • any type of skin infection;
  • a skin reaction to any steroid medicine;
  • liver disease; or
  • an adrenal gland disorder.

Topical corticosteroids can increase the glucose (sugar) levels in your blood or urine. Tell your doctor if you have diabetes.

Children are more susceptible to systemic absorption of topical corticosteroids. Bryhali is not approved for use by anyone younger than 18 years old.

It is not known whether halobetasol topical will harm an unborn baby. Tell your doctor if you are pregnant. If you are instructed to use Bryhali, use only a small amount for the shortest time possible.

It may not be safe to breastfeed while using this medicine. If you are instructed to use Bryhali, use only a small amount for the shortest time possible. Do not apply to the breasts.

How do I use Bryhali?

Apply Bryhali exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

Do not take it by mouth or use it intravaginally. Topical medicine is for use only on the skin. Do not use on open wounds or sunburned, windburned, dry, or irritated skin. Rinse with water if Bryhali gets in your eyes or mouth.

  • Wash your hands before and after using Bryhali, unless you are using this medicine to treat the skin on your hands.
  • Apply a thin layer of Bryhali lotion to the affected areas once daily. Rub in gently and completely. Do not apply this medicine over a large area of skin unless your doctor has told you to.

Do not cover the treated skin area with a bandage or other covering unless your doctor tells you to. Covering treated areas can increase the amount of medicine absorbed through your skin and may cause harmful effects.

Bryhali lotion is for short-term use only (up to 8 weeks). Follow your doctor’s dosing instructions very carefully.  Clinical trials have shown Bryhali continues to provide relief from psoriasis for up to 4 weeks after stopping using it.

Call your doctor if your symptoms do not improve after 8 weeks, or if they get worse. Stop using the product if your symptoms improve sooner.

What happens if I miss a dose?

Apply the product as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not apply two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line if anyone has accidentally swallowed the medication.

High doses or long-term use of Bryhali lotion can lead to thinning skin, easy bruising, changes in body fat (especially in your face, neck, back, and waist), increased acne or facial hair, menstrual problems, impotence, or loss of interest in sex.

What should I avoid while using Bryhali?

  • Avoid applying Bryhali to your face, scalp, underarms, or groin area. Do not use it to treat any skin condition that has not been checked by your doctor.
  • Avoid using other topical steroid medications on the areas you treat with Bryhali unless your doctor tells you to.
  • Do not use more than 50 grams per week.

What are the side effects of Bryhali?

Get emergency medical help if you have signs of an allergic reaction to Bryhali such as hives; difficulty breathing; or swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have:

  • worsening of your skin condition;
  • redness, warmth, swelling, oozing, or severe irritation of any treated skin;
  • blurred vision, tunnel vision, eye pain, or seeing halos around lights;
  • high blood sugar – increased thirst, increased urination, dry mouth, fruity breath odor; or
  • possible signs of absorbing this medicine through your skin – weight gain (especially in your face or your upper back and torso), slow wound healing, thinning or discolored skin, increased body hair, muscle weakness, nausea, diarrhea, tiredness, mood changes, menstrual changes, sexual changes.

Common Bryhali side effects may include:

  • upper respiratory tract infection
  • burning, stinging, itching, or dryness of treated skin
  • high blood sugar levels.

Other side effects that may occur with topical corticosteroids include:

  • acne
  • discoloration of the skin where the tape has been applied
  • dryness
  • excessive hair growth
  • miliaria
  • ophthalmic side effects such as cataracts or glaucoma
  • perioral dermatitis and allergic contact dermatitis
  • redness or crusting around your hair follicles (folliculitis)
  • skin thinning
  • spider veins
  • stretch marks.

Topical corticosteroids can cause reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for glucocorticosteroid insufficiency.

If you develop a skin infection while using Bryhali your doctor may give you an antimicrobial cream to use as well. If this does not resolve the infection, your doctor may discontinue the tape until the infection has cleared.

Brukinsa https://drugonomy.com/2026/02/09/brukinsa/ https://drugonomy.com/2026/02/09/brukinsa/#respond Mon, 09 Feb 2026 20:56:52 +0000 https://drugonomy.com/?p=11242 What is Brukinsa?

Brukinsa is used to treat adults with mantle cell lymphoma, Waldenström’s macroglobulinemia, marginal zone lymphoma, chronic lymphocytic leukemia, small lymphocytic lymphoma, and follicular lymphoma. It is an oral capsule or tablet that is taken once or twice a day.

Brukinsa (zanubrutinib) was first approved in 2019. There is no generic.

FDA approvals and indications

Brukinsa is a prescription oral capsule or tablet used to treat adults with:

  • Chronic lymphocytic leukemia (CLL)
  • Small lymphocytic lymphoma (SLL)
  • Follicular lymphoma (FL), in combination with obinutuzumab, whose disease has come back or did not respond to treatment (relapsed or refractory) and who have received at least 2 prior treatments
  • Mantle cell lymphoma (MCL), who have received at least 1 prior treatment for their cancer.
  • Waldenström’s macroglobulinemia (WM)
  • Marginal zone lymphoma (MZL), when the disease has come back or did not respond to treatment (relapsed or refractory), and who have received at least one anti-CD20-based regimen.

It is not known if this medicine is safe and effective in children.

How does Brukinsa work?

Brukinsa is a targeted treatment, not a chemotherapy drug, and works by directly blocking an enzyme, called Bruton’s tyrosine kinase (BTK), preventing its activity.

  • BTK is a signaling molecule for pathways that cause an increase in B cells, a type of white blood cell that makes infection-fighting antibodies.
  • Inhibition of BTK reduces the growth and spread of malignant B cells.

Brukinsa belongs to the drug class called BTK inhibitors.

Side effects

The most common side effects of Brukinsa are:

  • diarrhea or constipation
  • low platelet or other blood cell counts
  • easy bruising or bleeding
  • musculoskeletal pain
  • high blood pressure
  • a rash
  • cold or flu symptoms, such as stuffy nose, sneezing, sore throat, or cough.

Serious side effects and warnings

Get emergency medical help if you have signs of an allergic reaction to Brukinsa. Symptoms may include hives, difficulty breathing, or swelling of your face, lips, tongue, or throat.

Brukinsa can cause the following serious or life-threatening side effects:

  • Severe bleeding. Bleeding problems are common with Brukinsa, and can be serious and may
    lead to death. Your risk of bleeding may increase if you are also taking a blood thinner medicine. Tell your healthcare provider if you have any signs or symptoms of bleeding, including:
    • blood in your stools or black stools (looks like tar)
    • pink or brown urine
    • unexpected bleeding, or bleeding that is severe or you cannot control

Antihistamine/ Nasal Decongestant/ Antitussive syrup for oral administration.

Bromfed DM – Clinical Pharmacology

Brompheniramine maleate is a histamine antagonist, specifically an H1-receptor-blocking agent belonging to the alkylamine class of antihistamines. Antihistamines appear to compete with histamine for receptor sites on effector cells. Brompheniramine also has anticholinergic (drying) and sedative effects. Among the antihistaminic effects, it antagonizes the allergic response (vasodilation, increased vascular permeability, increased mucus secretion) of nasal tissue. Brompheniramine is well absorbed from the gastrointestinal tract, with peak plasma concentration after single, oral dose of 4 mg reached in 5 hours; urinary excretion is the major route of elimination, mostly as products of biodegradation; the liver is assumed to be the main site of metabolic transformation.

Pseudoephedrine acts on sympathetic nerve endings and also on smooth muscle, making it useful as a nasal decongestant. The nasal decongestant effect is mediated by the action of pseudoephedrine on α-sympathetic receptors, producing vasoconstriction of the dilated nasal arterioles. Following oral administration, effects are noted within 30 minutes with peak activity occurring at approximately one hour.

Dextromethorphan acts centrally to elevate the threshold for coughing. It has no analgesic or addictive properties. The onset of antitussive action occurs in 15 to 30 minutes after administration and is of long duration.

Indications and Usage for Bromfed DM

Bromfed™ DM (Brompheniramine Maleate, Pseudoephedrine Hydrochloride, and Dextromethorphan Hydrobromide Oral Syrup) is indicated for relief of coughs and upper respiratory symptoms, including nasal congestion, associated with allergy or the common cold.

Contraindications

Hypersensitivity to any of the ingredients. Do not use in the newborn, in premature infants, in nursing mothers, or in patients with severe hypertension or severe coronary artery disease. Do not use dextromethorphan in patients receiving monoamine oxidase inhibitors (MAOIs) .

Antihistamines should not be used to treat lower respiratory tract conditions including asthma.

Warnings

Especially in infants and small children, antihistamines in overdosage may cause hallucinations, convulsions, and death.

Antihistamines may diminish mental alertness. In the young child, they may produce excitation.

Precautions

General

Because of its antihistamine component, Bromfed™ DM Syrup (Brompheniramine Maleate, Pseudoephedrine Hydrochloride, and Dextromethorphan Hydrobromide Oral Syrup) should be used with caution in patients with a history of bronchial asthma, narrow angle glaucoma, gastrointestinal obstruction, or urinary bladder neck obstruction. Because of its sympathomimetic component, Bromfed™ DM Syrup should be used with caution in patients with diabetes, hypertension, heart disease, or thyroid disease.

Information for Patients

Patients should be warned about engaging in activities requiring mental alertness, such as driving a car or operating dangerous machinery.

Drug Interactions

Monoamine oxidase inhibitors (MAOIs)

Hyperpyrexia, hypotension, and death have been reported coincident with the coadministration of MAOIs and products containing dextromethorphan. In addition, MAOIs prolong and intensify the anticholinergic (drying) effects of antihistamines and may enhance the effect of pseudoephedrine. Concomitant administration of Bromfed™ DM Syrup and MAOIs should be avoided.

Central nervous system (CNS) depressants

Antihistamines have additive effects with alcohol and other CNS depressants (hypnotics, sedatives, tranquilizers, antianxiety agents, etc.).

Antihypertensive drugs

Sympathomimetic may reduce the effects of antihypertensive drugs.

Carcinogenesis, Mutagenesis, Impairment of Fertility

Animal studies of Bromfed™ DM Syrup to assess the carcinogenic and mutagenic potential or the effect on fertility have not been performed.

Pregnancy

Teratogenic Effects

Animal reproduction studies have not been conducted with Bromfed™ DM Syrup. It is also not known whether Bromfed™ DM Syrup can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. It should be given to a pregnant woman only if clearly needed.

Reproduction studies of brompheniramine maleate (a component of Bromfed™ DM Syrup) in rats and mice at doses up to 16 times the maximum human doses have revealed no evidence of impaired fertility or harm to the fetus.

Nursing Mothers

Because of the higher risk of intolerance of antihistamines in small infants generally, and in newborns and prematures in particular, Bromfed™ DM Syrup is contraindicated in nursing mothers.

Pediatric Use

Safety and effectiveness in pediatric patients below the age of 6 months have not been established

Geriatric Use

Clinical studies of Bromfed™ DM Syrup (Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide Oral Syrup) did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. However, antihistamines are more likely to cause dizziness, sedation, and hypotension in elderly patients. The elderly are also more likely to experience adverse reactions to sympathomimetics. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Adverse Reactions/Side Effects

The most frequent adverse reactions to Bromfed™ DM Syrup (Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide Oral Syrup) are: sedation; dryness of mouth, nose and throat; thickening of bronchial secretions; dizziness. Other adverse reactions may include:

Dermatologic:Urticaria, drug rash, photosensitivity, pruritus.

Cardiovascular System:Hypotension, hypertension, cardiac arrhythmias, palpitation.

CNS:Disturbed coordination, tremor, irritability, insomnia, visual disturbances, weakness, nervousness, convulsions, headache, euphoria, and dysphoria.

G.U. System:Urinary frequency, difficult urination.

G.I. System:Epigastric discomfort, anorexia, nausea, vomiting, diarrhea, constipation.

Respiratory System:Tightness of chest and wheezing, shortness of breath.

Hematologic System:Hemolytic anemia, thrombocytopenia, agranulocytosis.

Overdosage

Signs and Symptoms:

Central nervous system effects from overdosage of brompheniramine may vary from depression to stimulation, especially in children. Anticholinergic effects may be noted. Toxic doses of pseudoephedrine may result in CNS stimulation, tachycardia, hypertension, and cardiac arrhythmias; signs of CNS depression may occasionally be seen. Dextromethorphan in toxic doses will cause drowsiness, ataxia, nystagmus, opisthotonos, and convulsive seizures.

Toxic Doses:

Data suggest that individuals may respond in an unexpected manner to apparently small amounts of a particular drug. A 2½-year-old child survived the ingestion of 21 mg/kg of dextromethorphan exhibiting only ataxia, drowsiness, and fever, but seizures have been reported in 2 children following the ingestion of 13–17 mg/kg. Another 2½-year-old child survived a dose of 300–900 mg of brompheniramine. The toxic dose of pseudoephedrine should be less than that of ephedrine, which is estimated to be 50 mg/kg.

Treatment:

Induce emesis if patient is alert and is seen prior to 6 hours following ingestion. Precautions against aspiration must be taken, especially in infants and small children. Gastric lavage may be carried out, although in some instances tracheostomy may be necessary prior to lavage. Naloxone hydrochloride 0.005 mg/kg intravenously may be of value in reversing the CNS depression that may occur from an overdose of dextromethorphan. CNS stimulants may counter CNS depression. Should CNS hyperactivity or convulsive seizures occur, intravenous short-acting barbiturates may be indicated. Hypertensive responses and/or tachycardia should be treated appropriately. Oxygen, intravenous fluids, and other supportive measures should be employed as indicated.

Bromfed DM Dosage and Administration

Adults and pediatric patients 12 years of age and over:10 mL (2 teaspoonfuls) every 4 hours.

Children 6 to under 12 years of age:5 mL (1 teaspoonful) every 4 hours.

Children 2 to under 6 years of age:2.5 mL (½ teaspoonful) every 4 hours.

Infants 6 months to under 2 years of age:Dosage to be established by a physician.

Do not exceed 6 doses during a 24-hour period.

Briviact https://drugonomy.com/2026/02/04/briviact/ https://drugonomy.com/2026/02/04/briviact/#respond Wed, 04 Feb 2026 08:40:41 +0000 https://drugonomy.com/?p=11234 What is Briviact?

Briviact (brivaracetam) is an anti-epileptic drug (also called an anticonvulsant) that may be used to treat partial onset seizures in adults and children 1 month and older with epilepsy.

  • Briviact is often used along with other seizure medicines to give better control over seizures.

Briviact works in the brain to help control seizures and is thought to target a specific protein called SV2A that helps nerve cells communicate with each other. By attaching to this protein, Briviact helps balance the brain’s electrical activity and this mechanism can stop the sudden bursts of electricity that cause seizures.

Briviact gained FDA approval on February 18, 2016. There is currently no Briviact generic available.

Is Briviact a controlled substance?

Briviact is a federally controlled substance (Schedule V) because it can be abused or lead to dependence.

Keep Briviact in a safe place to prevent misuse and abuse. Selling or giving away Briviact may harm others and is against the law. 

Briviact side effects

The most common side effects of Briviact are:

  • sleepiness
  • dizziness
  • feeling tired
  • nausea and vomiting.

Side effects of Briviact in children 1 month to less than 16 years of age are similar to those seen in adults.

Serious side effects and warnings

Briviact may cause the following serious side effects.

Suicidal thoughts and behaviors. Like other antiepileptic drugs, Briviact may cause suicidal thoughts or actions in a very small number of people; about 1 in 500 people taking it. Call a healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you:

  • thoughts about suicide or dying
  • new or worse depression
  • feeling agitated or restless
  • trouble sleeping (insomnia)
  • acting aggressive, feeling angry, or being violent
  • an extreme increase in activity and talking (mania)
  • attempts to commit suicide
  • new or worse anxiety
  • panic attacks
  • new or worse irritability
  • acting on dangerous impulses
  • other unusual changes in behavior or mood.

Suicidal thoughts or actions can be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes. Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. Keep all follow-up visits with your healthcare provider as scheduled. Call your healthcare provider between visits as needed, especially if you are worried about symptoms.

Briumvi https://drugonomy.com/2026/02/04/briumvi/ https://drugonomy.com/2026/02/04/briumvi/#respond Wed, 04 Feb 2026 08:34:37 +0000 https://drugonomy.com/?p=11231 What is Briumvi?

Briumvi is used to treat relapsing forms of multiple sclerosis (MS) in adults, including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease. It is given as an intravenous infusion every 6 months by a healthcare provider.

Clinical trials report that Briumvi is superior to teriflunomide at reducing relapses and significantly reducing brain lesions on magnetic resonance imaging (MRI).

  • 49 % to 59 % fewer relapses were reported with Briumvi vs teriflunomide in 2 clinical trials.
  • Both studies also reported near complete (97%) suppression of brain lesions (T1 Gd+ lesions) per MRI over 2 years.
  • Zero relapses were reported in 86% to 87% of people taking Briumvi.

Briumvi (ublituximab-xiiy) gained FDA approval on December 28, 2022. There is no generic or biosimilar.

How does Briumvi work?

Briumvi’s mechanism of action involves targeting and destroying B cells (a type of immune cell) in the body. It does this by binding to a protein called CD20 on the B cells’ surface. By reducing B cells, Briumvi helps mitigate the immune system’s effect on the nervous system, which drives MS symptoms. 

Briumvi belongs to the drug class called CD20 monoclonal antibodies.

Briumvi side effects

The most common Briumvi side effects are:

  • infusion reactions, which may include symptoms such as dizziness, nausea, light-headed, itchy, sweaty, headache, chest tightness, back pain, trouble breathing, or swelling in your face;
  • cold sores around your mouth (herpes infections), skin sores or blisters, itching, tingling, burning pain in your thigh or lower back;
  • cold symptoms such as stuffy nose, sneezing, sore throat;
  • pain in your hands and feet;
  • sleep problems (insomnia); or
  • tiredness.

Serious side effects and warnings

Briumvi can cause the following serious side effects.

Infusion reactions. Infusion reactions are one of the most common side effects of Briumvi. Infusion reactions can be serious and may require you to be hospitalized. You will be monitored during your infusion and may be monitored after each infusion of Briumvi for signs and symptoms of an infusion reaction. Tell your healthcare provider if you get any of these symptoms:

  • fever
  • itchy skin
  • wheezing
  • chills
  • dizziness
  • nausea
  • headache
  • feeling faint
  • abdominal pain
  • flu-like symptoms
  • swelling of the tongue or throat
  • throat irritation
  • fast heartbeat
  • trouble breathing
  • red face or skin
  • hives.

These infusion reactions can happen over 24 hours after your infusion. You must call your healthcare provider right away if you get any of the signs or symptoms listed above after each infusion. If you get an infusion reaction, your healthcare provider may need to stop or slow down the rate of your infusion.

Infections. Infections are a common side effect, and upper respiratory tract infections are one of the most common side effects of Briumvi. Briumvi increases your risk of getting infections caused by bacteria or viruses that may be life-threatening or cause death. Tell your healthcare provider if you have an infection or have any of the following signs of infection, including fever, chills, a cough that does not go away, or painful urination. Your healthcare provider should delay your treatment with Briumvi until your infection is gone.

Hepatitis B virus (HBV) reactivation: Before starting treatment with Briumvi, your healthcare provider will do blood tests to check for hepatitis B viral infection. If you have ever had a hepatitis B virus infection, the hepatitis B virus may become active again during or after treatment with Briumvi. Hepatitis B virus becoming active again (called reactivation) may cause serious liver problems, including liver failure or death. Your healthcare provider will monitor you if you are at risk for hepatitis B virus reactivation during treatment and after you stop receiving Briumvi.

Weakened immune system: Briumvi taken before or after other medicines that weaken the immune system could increase your risk of getting infections.

Progressive Multifocal Leukoencephalopathy (PML): PML may happen with Briumvi. PML is a rare, serious brain infection caused by a virus that may get worse over days or weeks. PML can result in death or severe disability. Tell your healthcare provider right away if you have any new or worsening neurologic signs or symptoms. These symptoms may include weakness on one side of your body, loss of coordination in arms and legs, vision problems, and changes in thinking and memory, which may lead to confusion, and personality changes.

Low immunoglobulins: Briumvi may cause a decrease in some types of antibodies. Your healthcare provider will do blood tests to check your blood immunoglobulin levels.

Briumvi may also cause an allergic reaction. Get emergency medical help if you have signs of an allergic reaction to Briumvi, such as hives, difficulty breathing, or swelling of your face, lips, tongue, or throat.

It is not known if Briumvi is safe or effective in children.

This is not a complete list of side effects, and others may occur. Call your doctor for medical advice about side effects.

Brilinta https://drugonomy.com/2026/02/04/brilinta/ https://drugonomy.com/2026/02/04/brilinta/#respond Wed, 04 Feb 2026 08:27:54 +0000 https://drugonomy.com/?p=11228 What is Brilinta?

Brilinta prevents platelets in your blood from sticking together to form an unwanted blood clot that could block an artery.

Brilinta is used to lower your risk of heart attack, stroke, or death due to a blocked artery or a prior heart attack.

Brilinta is also used to lower your risk of blood clots if you have coronary artery disease (decreased blood flow to the heart) and have been treated with stents to open clogged arteries.

Brilinta is also used to lower your risk of a first heart attack or stroke if you have decreased blood flow to the heart.

Brilinta is also used to lower the risk of stroke and death in adults with a blockage or decreased blood flow in an artery that supplies blood to the brain.

This medicine is usually given together with low-dose aspirin. Carefully follow your doctor’s dosing instructions. Using too much aspirin can make ticagrelor less effective.

Warnings

You should not use Brilinta if you have any active bleeding (including a bleeding stomach ulcer), or a history of bleeding in the brain. Do not use this medicine just before heart bypass surgery (coronary artery bypass graft, or CABG).

You may need to stop using this medicine for a short time before having surgery or dental work, to prevent excessive bleeding. Do not stop taking Brilinta without first talking to your doctor, even if you have signs of bleeding. Stopping this medicine may increase your risk of a heart attack or stroke.

Brilinta may cause you to bleed more easily, which can be severe or life-threatening. Avoid activities that may increase your risk of bleeding or injury.

Call your doctor or seek emergency medical attention if you have bleeding that will not stop. You may also have bleeding on the inside of your body, such as in your stomach or intestines. Call your doctor at once if you have black or bloody stools, red or pink urine, or if you cough up blood or vomit that looks like coffee grounds. These could be signs of internal bleeding.

Many drugs (including some over-the-counter medicines and herbal products) can cause serious medical problems if you take them with Brilinta. It is very important to tell your doctor about all medicines you have recently used.

Before taking this medicine

You should not use Brilinta if you are allergic to ticagrelor, or if you have:

  • any active bleeding; or
  • a history of bleeding in the brain (such as from a head injury).

Tell your doctor if you have ever had:

  • a stroke;
  • heart problems;
  • high cholesterol;
  • bleeding problems;
  • a stomach ulcer or colon polyps;
  • liver disease; or
  • kidney disease;
  • asthma, COPD (chronic obstructive pulmonary disorder) or other breathing problems;
  • recent surgery or serious injuries; or
  • if you are planning to have surgery or a dental procedure; or

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

It is not known whether Brilinta passes into breastmilk. Talk to your doctor before using Brilinta if you are breastfeeding.

How should I take Brilinta?

Take Brilinta exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Brilinta is taken together with aspirin. Use these medicines exactly as directed.

Do not take more aspirin than your doctor has prescribed. Taking too much aspirin can make Brilinta less effective.

Take this medicine at the same time each day, with or without food.

If you cannot swallow a tablet whole, crush the pill and mix it with water. Stir and drink this mixture right away. Add more water to the glass, stir, and drink right away.

Brilinta keeps your blood from coagulating (clotting) and can make it easier for you to bleed, even from a minor injury. Contact your doctor or seek emergency medical attention if you have any bleeding that will not stop.

To prevent excessive bleeding, you may need to stop using Brilinta for a short time before a surgery, medical procedure, or dental work. Any healthcare provider who treats you should know that you are taking ticagrelor.

Do not stop taking Brilinta without first talking to your doctor, even if you have signs of bleeding. Stopping the medicine could increase your risk of a heart attack or stroke.

Ticagrelor may affect medical testing for platelets in your blood and you may have false results. Tell the laboratory staff that you use Brilinta.

Store at room temperature away from moisture and heat.

Breyanzi https://drugonomy.com/2026/02/04/breyanzi/ https://drugonomy.com/2026/02/04/breyanzi/#respond Wed, 04 Feb 2026 07:36:06 +0000 https://drugonomy.com/?p=11220 What is Breyanzi?

Breyanzi is used to treat 5 types of non-Hodgkin lymphoma, including large B-cell lymphoma (LBCL), chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL), follicular lymphoma (FL), and relapsed or refractory mantle cell lymphoma (MCL), with relapsed or refractory (R/R) marginal zone lymphoma (MZL) in specific patients.

Breyanzi is a one-time infusion of CAR T cell therapy that may help you have complete and lasting remission. 

Breyanzi is a cancer treatment created using immune cells, called T cells, collected from the patient’s own blood. The T cells are modified to become CAR T cells and are then infused back into the patient’s body. The CART T cells can attach to the cancer cells and kill them, helping clear the cancer from the body.  Before your infusion, you will have chemotherapy to prepare your body for your treatment. 

Breyanzi FDA approval was first received on February 5, 2021, for the company Bristol Myers Squibb (BMS).  It contains lisocabtagene maraleuce. The most recent approval was for relapsed or refractory marginal zone lymphoma (MZL) on December 4, 2025.

What is Breyanzi used for?

Breyanzi is FDA-approved to treat five types of non-Hodgkin lymphoma: large B-cell lymphoma, relapsed or refractory chronic CLL/SLL, relapsed or refractory follicular lymphoma (FL), and relapsed or refractory mantle cell lymphoma (MCL), and relapsed or refractory (R/R) marginal zone lymphoma (MZL)  in specific patients.

Large B-cell lymphoma

Breyanzi is used to treat large B-cell lymphoma (LBCL), including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (including DLBCL arising from indolent lymphoma), high-grade B-cell lymphoma, primary mediastinal large B-cell lymphoma, and follicular lymphoma grade 3B, in adults. You can only be treated with Breyanzi if:

  • your first treatment has not worked, or your cancer returned within a year of your first treatment, OR
  • your first treatment has not worked, or your cancer returned after the first treatment, and you are not eligible for hematopoietic stem cell transplantation because of medical conditions or age, OR
  • two or more kinds of treatment have not worked or stopped working.

It is not indicated for the treatment of primary central nervous system lymphoma.

Relapsed or refractory chronic CLL/SLL

Breyanzi is used to treat relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) in adults who have:

  • received at least 2 prior lines of therapy, including a Bruton tyrosine kinase (BTK) inhibitor and a B-cell lymphoma 2 (BCL-2) inhibitor. 
  • This is an accelerated FDA approval.

Relapsed or refractory follicular lymphoma (FL) 

Breyanzi is used to treat relapsed or refractory follicular lymphoma (FL) in adults who have:

  • received 2 or more prior lines of systemic therapy. 
  • This is an accelerated FDA approval.

Relapsed or Refractory Mantle Cell Lymphoma (MCL)

It is approved for treating adult patients with relapsed or refractory mantle cell lymphoma (MCL) who have received at least 2 prior lines of systemic therapy, including a Bruton tyrosine kinase (BTK) inhibitor.

Relapsed or refractory (R/R) marginal zone lymphoma (MZL)

Tell your caregivers right away if you have signs of this condition: fever, chills, dizziness, confusion, vomiting, diarrhea, fast heartbeats, trouble breathing, or feeling very weak or tired. Your caregivers will have medication available to treat CRS if it occurs.

Breyanzi may cause other serious side effects. Call your doctor at once if you have:

  • problems with speech;
  • confusion, trouble concentrating, memory problems;
  • decreased consciousness;
  • tremors, or a seizure; or
  • signs of infection – fever, chills, tiredness, mouth sores, skin sores, easy bruising, unusual bleeding, pale skin, cold hands and feet, feeling light-headed or short of breath.

Breyanzi may increase your risk of developing certain cancers. Talk to your doctor about the risks of receiving this medication. This medication may cause other side effects. Call your doctor if you have any unusual problems while receiving this medication. If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration’s (FDA) MedWatch Adverse Event Reporting program online .

How will I receive Breyanzi?

Breyanzi is a one-time cancer treatment made from your own white blood cells. The process takes several weeks and involves collecting, modifying, and then infusing those cells back into your body, with close monitoring for side effects.

Breyanzi is a liquid medicine given intravenously (into a vein) by a doctor or nurse. It is usually given as two infusions over about 30 minutes total as a one-time dose.

Breyanzi treatment process

Step 1: T Cell collection

  • T cells, which are a type of white blood cell, are collected using a procedure called leukapheresis (a process that removes white blood cells from the body).

Step 2: T Cell activation

  • The collected T cells are sent away and modified so they can better recognize and attack cancer cells.
  • This modification process takes about 3–4 weeks.

Step 3: Preparation for infusion

  • You will receive chemotherapy medicines a few days before Breyanzi to prepare your body; this is called lymphodepleting chemotherapy.

Step 4: Breyanzi infusion

  • The modified cells are then infused back into your body as Breyanzi. Because the treatment is made from your own cells, it must only be given to you.

Step 5: Follow-up

  • Your healthcare provider will check if the treatment is working and monitor for side effects.
    You should plan to stay near the treatment center for at least 4 weeks after receiving Breyanzi.

It is very important not to miss your cell collection or treatment appointment

Before taking this medicine

Tell your doctor if you have ever had:

  • hepatitis B or C; or
  • if you have received a vaccine within the past 6 weeks.

Using Breyanzi may increase your risk of developing other cancers. Ask your doctor about this risk.

Tell your doctor if you are pregnant or breastfeeding.

You may need to have a negative pregnancy test before starting this treatment.

Warnings

Breyanzi has a boxed warning for cytokine release syndrome(CRS), neurologic toxicity, and secondary hematological malignancies.

Cytokine release syndrome (CRS): This is a common but serious side effect of this medicine is called cytokine release syndrome, which causes fever, chills, trouble breathing, vomiting, and other symptoms. Your caregivers will have medication available to treat this condition if it occurs.

Breyanzi may cause severe or life-threatening central nervous system reactions. These reactions can occur after treatment with this medicine. Tell your doctor if you have or have ever had seizures, a stroke, or memory loss. If you experience any of the following symptoms, tell your doctor immediately: headache, dizziness, difficulty falling asleep or staying asleep, restlessness, confusion, anxiety, uncontrollable shaking of a part of the body, loss of consciousness, agitation, seizures, loss of balance, or difficulty speaking.

T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies, including this therapy.

What should I avoid after receiving Breyanzi?

 Avoid driving or operating machinery for at least 2 weeks after receiving this treatment. This medicine can cause weakness, drowsiness, confusion, problems with memory or coordination, and seizures.

Do not donate blood, organs, tissues, or cells for transplantation.

Do not have any vaccinations without talking to your doctor for at least 6 weeks before starting chemotherapy, during your Breyanzi treatment, and until your doctor tells you your immune system has recovered

What other drugs will affect Breyanzi?

Other drugs may affect this medicine, including prescription and over-the-counter medicines, vitamins, and herbal products. You should keep a written list of all the prescription and nonprescription (over-the-counter) medicines you take, along with any products such as vitamins, minerals, or other dietary supplements. Remember to bring this list with you each time you see a doctor or are hospitalized. This information is important to have on hand for emergencies.

Brexpiprazole https://drugonomy.com/2026/02/04/brexpiprazole/ https://drugonomy.com/2026/02/04/brexpiprazole/#respond Wed, 04 Feb 2026 07:26:52 +0000 https://drugonomy.com/?p=11217 What is brexpiprazole?

Brexpiprazole is used to treat major depressive disorder in adults (in addition to other medications), schizophrenia in adults and children aged 13 years and older, and agitation that may happen with dementia due to Alzheimer’s disease. It is an oral tablet taken once a day.

Brexpiprazole belongs to the drug class called atypical antipsychotics.

Brexpiprazole first gained FDA approval on July 10, 2015 under the brand name Rexulti. There is a generic brexpiprazole but it is only approved for adults with depression or schizophrenia. The brand Rexulti has additional approvals for adolescents 13 years and older with schizophrenia and for Alzheimer’s disease-related agitation.

Mechanism

Brexpiprazole works by correcting the imbalance of natural chemical messengers  (neurotransmitters), such as dopamine and serotonin in the brain. This imbalance is thought to be associated with several psychiatric disorders such as schizophrenia, depression, and agitation associated with Alzheimer’s disease.

Brexpiprazole uses

Brexpiprazole is an atypical antipsychotic used:

  • along with antidepressant medicines to treat major depressive disorder (MDD) in adults
  • to treat schizophrenia in adults and children ages 13 years and older
  • to treat agitation that may happen with dementia due to Alzheimer’s disease.

Brexpiprazole should not be used as an “as needed” treatment for agitation that may happen with dementia due to Alzheimer’s disease.

Clinical trials have not been conducted in children so it is not known if brexpiprazole is safe and effective for the treatment of MDD in children under the age of 18 or for the treatment of schizophrenia in children under 13 years.

Brexpiprazole side effects

The most common side effects of brexpiprazole are:

  • weight gain
  • sleepiness
  • dizziness
  • common cold symptoms
  • restlessness or feeling like you need to move (akathisia).

Serious side effects and warnings

Brexpiprazole carries a Boxed Warning for an increased risk of death in elderly patients with dementia-related psychosis.

Increased risk of death in elderly people with dementia-related psychosis. Trials have reported medicines like brexpiprazole can raise the risk of death in elderly people who have lost touch with reality (psychosis) due to confusion and memory loss (dementia). Brexpiprazole is not approved for dementia-related psychosis without agitation that may happen with Alzheimer’s disease.

Increased risk of suicidal thoughts and actions. Brexpiprazole and antidepressant medicines increase the risk of suicidal thoughts and actions in people 24 years of age and younger, especially within the first few months of treatment or when the dose is changed. Depression and other mental illnesses are the most important causes of suicidal thoughts and actions.

  • Pay close attention to any changes, especially sudden changes in mood, behaviors, thoughts, or feelings, or if you develop suicidal thoughts or actions. This is very important when brexpiprazole or the antidepressant medicine is started or when the dose is changed.
  • Call your healthcare provider right away to report new or sudden changes in mood, behavior, thoughts, or feelings, or if you develop suicidal thoughts or actions.
  • Keep all follow-up visits with your healthcare provider as scheduled. Call your healthcare provider between visits as needed, especially if you have concerns about symptoms.

Call a healthcare provider right away if you or your family member have any of the following symptoms, especially if they are new, worse, or worry you:

  • thoughts about suicide or dying
  • attempts to commit suicide
  • new or worsening depression
  • new or worsening anxiety
  • feeling very agitated or restless
  • panic attacks
  • trouble sleeping (insomnia)
  • new or worsening irritability
  • acting aggressive, being angry, or violent
  • acting on dangerous impulses
  • an extreme increase in activity or talking (mania)
  • other unusual changes in behavior or mood.

Other serious side effects of brexpiprazole include the following.

Cerebrovascular problems (these involve the blood vessels of the brain), including stroke, in elderly people with dementia-related psychosis that can lead to death.

Neuroleptic malignant syndrome (NMS), which is a rare and life-threatening reaction to antipsychotic drugs. Call your healthcare provider or go to the nearest hospital emergency room right away if you have some or all of the following signs and symptoms of NMS:

  • high fever
  • stiff muscles
  • confusion
  • changes in your pulse, blood pressure, heart rate, and breathing
  • increased sweating.

Uncontrolled body movements (tardive dyskinesia). Brexpiprazole may cause movements that you cannot control in your face, tongue, or other body parts. Tardive dyskinesia may not go away, even if you stop taking brexpiprazole. Tardive dyskinesia may also start after you stop taking brexpiprazole.

Brexpiprazole may also cause problems with your metabolism such as:

  • High blood sugar (hyperglycemia) and diabetes. Increases in blood sugar can happen in some people who take brexpiprazole. Extremely high blood sugar can lead to coma or death. Your healthcare provider should check your blood sugar before you start, or soon after you start brexpiprazole and then regularly during long term treatment with brexpiprazole. Call your healthcare provider if you have any of these symptoms of high blood sugar during treatment with brexpiprazole:
    • feel very thirsty
    • feel very hungry
    • feel sick to your stomach
    • need to urinate more than usual
    • feel weak or tired
    • feel confused, or your breath smells fruity
  • Increased fat levels (cholesterol and triglycerides) in your blood. Your healthcare provider should check the fat levels in your blood before you start, or soon after you start brexpiprazole, and then periodically during treatment with brexpiprazole.
  • Weight gain. You and your healthcare provider should check your weight before you start and often during treatment with brexpiprazole.

Unusual and uncontrollable (compulsive) urges. Some people taking brexpiprazole have had strong unusual urges, to gamble and gambling that cannot be controlled (compulsive gambling). Other compulsive urges include sexual urges, shopping, and eating or binge eating. If you or your family members notice that you are having new or unusual strong urges or behaviors, talk to your healthcare provider.

Low white blood cell count. Your healthcare provider may do blood tests during the first few months of treatment with brexpiprazole.

Decreased blood pressure (orthostatic hypotension) and fainting. You may feel dizzy, lightheaded, or pass out (faint) when you rise too quickly from a sitting or lying position.

Falls. Brexpiprazole may make you sleepy or dizzy, may cause a decrease in your blood pressure when changing position (orthostatic hypotension), and can slow your thinking and motor skills which may lead to falls that can cause fractures or other injuries.

Seizures (convulsions). Brexpiprazole may increase your risk of seizures.

Problems controlling your body temperature so that you feel too warm. See “What should I avoid while taking brexpiprazole?”

Difficulty swallowing that can cause food or liquid to get into your lungs.

Sleepiness, drowsiness, feeling tired, difficulty thinking and doing normal activities. See “What should I avoid while taking brexpiprazole?”

Brexpiprazole may harm an unborn baby.

These are not all the possible side effects of brexpiprazole. Call your doctor for medical advice about side effects.

Breo Ellipta https://drugonomy.com/2026/02/02/breo-ellipta/ https://drugonomy.com/2026/02/02/breo-ellipta/#respond Mon, 02 Feb 2026 09:58:19 +0000 https://drugonomy.com/?p=11213 What is Breo Ellipta?

Breo Ellipta inhalation powder contains a combination of fluticasone and vilanterol. Fluticasone is a steroid that prevents the release of substances in the body that cause inflammation. Vilanterol is a bronchodilator that works by relaxing muscles in the airways to improve breathing.

Breo Ellipta is a once-daily combination medicine used to treat asthma or COPD (chronic obstructive pulmonary disease), it helps improve breathing, reduce COPD flare-ups, and help prevent and control asthma symptoms. For asthma, it can be used by patients 5 years and older.

Breo Ellipta is not used to treat sudden, severe symptoms of COPD or asthma and does not replace a rescue inhaler

Vilanterol, when used alone, may increase the risk of death in people with asthma. However, this risk is not increased when fluticasone and vilanterol are used together as a combination product.

Warnings

Breo Ellipta is not a rescue medicine. It will not work fast enough to treat an asthma or bronchospasm attack.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Breo Ellipta may interact with other medicines and this may cause serious side effects. Tell your healthcare provider if you take antifungal or anti-HIV medicines.

Before taking this medicine

You should not use Breo Ellipta if you are allergic to fluticasone, vilanterol, or milk proteins.

Fluticasone can weaken your immune system, making it easier for you to get an infection or worsening an infection you already have or have recently had. Tell your doctor about any illness or infection you have had within the past several weeks.

To make sure Breo Ellipta is safe for you, tell your doctor if you have:

  • glaucoma or cataracts;
  • a weak immune system;
  • heart disease, high blood pressure;
  • liver disease;
  • a thyroid disorder;
  • a seizure;
  • diabetes;
  • any type of infection (bacterial, fungal, viral, or parasitic); or
  • osteoporosis.

Long-term use of steroids may lead to bone loss (osteoporosis), especially if you smoke, if you do not exercise, if you do not get enough vitamin D or calcium in your diet, or if you have a family history of osteoporosis. Talk with your doctor about your risk.

Tell your doctor if you are pregnant. It is not known whether Breo Ellipta will harm an unborn baby. However, having untreated or uncontrolled asthma during pregnancy may cause complications such as low birth weight, premature birth, or eclampsia (dangerously high blood pressure that can lead to medical problems in both mother and baby). The benefit of treating asthma may outweigh any risks to the baby.

It may not be safe to breast-feed while using this medicine. Ask your doctor about any risk.

Breo Ellipta is not approved for use by anyone younger than 4 years old.

How should I use Breo Ellipta?

Use Breo Ellipta inhalation powder exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Breo Ellipta is not a rescue medicine for asthma or bronchospasm attacks. Use only fast-acting inhalation medicine for an attack. Seek medical attention if your breathing problems get worse quickly, or if you think your asthma medications are not working as well.

Breo Ellipta is a powder that comes with a special inhaler device preloaded with blister packs containing measured doses of the medicine. The device opens and loads a blister of Breo Ellipta each time you use the inhaler. Follow the patient instructions provided with the inhaler device.

Use the medicine at the same time each day, and not more than once in a 24-hour period.

Your dose needs may change due to surgery, illness, stress, or a recent asthma attack. Do not change your Breo Ellipta dose or dosage schedule without your doctor’s advice.

Always rinse out your mouth with water after using the inhaler device, to help prevent thrush (a fungal infection in the mouth or throat).

While using Breo Ellipta, your doctor will need to check your lung function on a regular basis. Your vision and your bone mineral density may also need to be checked.

Once your asthma is under control, your doctor may want you to stop using Breo Ellipta. Keep all follow-up appointments and do not stop using the medicine unless your doctor tells you to.

Store Breo Ellipta at room temperature away from moisture, heat, and light. Keep the inhaler device in the sealed foil tray until ready to start using it.

Throw the inhaler device away 6 weeks after you have taken it out of the foil pouch, or if the dose indicator shows a zero, whichever comes first.

Boniva https://drugonomy.com/2026/02/02/boniva/ https://drugonomy.com/2026/02/02/boniva/#respond Mon, 02 Feb 2026 09:42:36 +0000 https://drugonomy.com/?p=11207 What is Boniva?

Boniva is a bisphosphonate medicine that alters bone formation and breakdown in the body. This can slow bone loss and may help prevent bone fractures.

Boniva is prescription medicine used to treat or prevent osteoporosis in women after menopause. Ibandronate helps increase bone mass and helps reduce the chance of having a spinal fracture.

It is not known how long Boniva works for the treatment and prevention of osteoporosis. You should see your doctor regularly to determine if this medicine is still right for you.

Warnings

You should not use Boniva if you have severe kidney disease or low levels of calcium in your blood.

Do not take a tablet if you have problems with your esophagus, or if you cannot sit upright or stand for at least 60 minutes after taking the tablet.

Boniva tablets can cause serious problems in the stomach or esophagus. Stop taking Boniva and call your doctor at once if you have chest pain, new or worsening heartburn, or pain when swallowing.

Also call your doctor if you have muscle spasms, numbness or tingling (in hands and feet or around the mouth), new or unusual hip pain, or severe pain in your joints, bones, or muscles.

Boniva side effects

Get emergency medical help if you have signs of an allergic reaction to Boniva: hives; wheezing, difficult breathing; swelling of your face, lips, tongue, or throat.

Stop using this medicine and call your doctor at once if you have:

  • chest pain, new or worsening heartburn;
  • difficulty or pain when swallowing;
  • pain or burning under the ribs or in the back;
  • severe heartburn, burning pain in your upper stomach, or coughing up blood;
  • new or unusual pain in your thigh or hip;
  • jaw pain, numbness, or swelling;
  • severe joint, bone, or muscle pain; or
  • low calcium levels – muscle spasms or contractions, numbness or tingly feeling (around your mouth, or in your fingers and toes).

Common Boniva side effects may include:

  • heartburn, stomach pain, diarrhea;
  • back pain, bone pain, muscle or joint pain;
  • pain in your arms or legs;
  • headache; or
  • fever, chills, tiredness, flu-like symptoms.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects.

Before taking this medicine

You should not use Boniva if you are allergic to ibandronate, or if you have:

  • severe kidney disease; or
  • low blood levels of calcium (hypocalcemia).

Do not take an Boniva tablet if you have problems with your esophagus, or if you cannot sit upright or stand for at least 60 minutes. Ibandronate can cause serious problems in the stomach or esophagus. You must stay upright for at least 1 full hour after taking this medicine.

To make sure this medicine is safe for you, tell your doctor if you have ever had:

  • trouble swallowing;
  • problems with your stomach or digestion;
  • hypocalcemia;
  • a dental problem (you may need a dental exam before you begin using Boniva);
  • kidney disease; or
  • any condition that makes it hard for your body to absorb nutrients from food (malabsorption).

In rare cases, this medicine may cause bone loss (osteonecrosis) in the jaw. Symptoms include jaw pain or numbness, red or swollen gums, loose teeth, or slow healing after dental work. The longer you use Boniva, the more likely you are to develop this condition.

Osteonecrosis of the jaw may be more likely if you have cancer or received chemotherapy, radiation, or steroids. Other risk factors include blood clotting disorders, anemia (low red blood cells), and a pre existing dental problem.

Talk with your doctor about the risks and benefits of using this medication.

It is not known whether ibandronate will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

It is not known whether ibandronate passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

How should I use Boniva?

Use Boniva exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Boniva tablets are taken once per month. The injection is given into a vein through an IV once every 3 months. The tablets can be taken at home, but a healthcare provider must give the injection.

Take the tablet first thing in the morning, at least 60 minutes before you eat or drink anything or take any other medicine. Take the medicine on the same day each month and always first thing in the morning.

Take the tablet with a full glass (6 to 8 ounces) of plain water. Do not use coffee, tea, soda, juice, or mineral water. Do not eat or drink anything other than plain water.

Do not crush, chew, or suck on a tablet. Swallow it whole.

For at least 60 minutes (1 full hour) after taking a tablet:

  • Do not lie down or recline.
  • Do not take any other medicine including vitamins, calcium, or antacids.

Pay special attention to your dental hygiene while using Boniva. Brush and floss your teeth regularly. Consult your dentist before starting Boniva to ensure that you don’t need dental work soon. If you need to have any dental work (especially surgery), tell the dentist ahead of time that you are using this medicine.

Boniva is only part of a complete program of treatment that may also include diet changes, exercise, bone mineral density testing, and taking calcium and vitamin supplements. Follow your doctor’s instructions very closely.

Store at room temperature away from moisture and heat.

Your doctor will determine how long to treat you with this medicine. Ibandronate is often given for only 3 to 5 years.

Blincyto https://drugonomy.com/2026/02/02/blincyto/ https://drugonomy.com/2026/02/02/blincyto/#respond Mon, 02 Feb 2026 09:35:31 +0000 https://drugonomy.com/?p=11204 What is Blincyto?

Blincyto (blinatumomab) is an injectable immunotherapy treatment that may be used to treat B-cell precursor acute lymphoblastic leukemia (ALL) in adults and children aged 1 month and older. It is a biologic treatment that is usually given after other cancer treatments have been tried without success.

Blincyto’s mechanism of action is to connect the protein CD3 found on the surface of T cells (a type of white blood cell that is an essential part of our immune system) to another protein, CD19 found on cancerous and non-cancerous B-cells. This activates the T-cell and Blincyto works by causing the destruction (lysis) of CD19 cells. Blincyto is a bispecific CD19-directed CD3 T-cell engager. In one study, 81% of patients with B-cell precursor ALL with minimal residual disease receiving Blincyto had no detectable cancer after 4 weeks.

Blincyto was FDA-approved on December 3, 2014. There is no generic Blincyto available.

What is Blincyto used for?

Blincyto is used to treat adults and children 1 month and older with:

  • B-cell precursor ALL in remission when only a small number of cancer cells remain in the body (minimal residual disease [MRD])
  • B-cell precursor ALL that has come back or did not respond to previous treatments
  • Philadelphia-chromosome negative B-cell precursor ALL in the consolidation phase of chemotherapy treatment with multiple phases.

It is not known if Blincyto is safe and effective in children under 1 month of age.

Blincyto side effects

The most common side effects of Blincyto include:

  • fever
  • infusion-related reactions (see below)
  • headache
  • infections
  • muscle, joint, and bone pain
  • low white or red blood cell counts (neutropenia or anemia)
  • low platelet count (thrombocytopenia)
  • diarrhea.

Some side effects may occur during the Blincyto injection. Tell your healthcare provider right away if you feel dizzy, nauseated, light-headed, chilled or feverish, or if you have a headache, skin rash, trouble breathing, or swelling in your face.

Serious side effects and warnings

Get emergency medical help if you have signs of an allergic reaction to Blincyto such as hives; difficulty breathing; or swelling of your face, lips, tongue, or throat.

Blincyto may cause serious side effects, including:

Cytokine release syndrome (CRS) and infusion reactions. CRS can occur when your immune system responds to immunotherapy medications such as Blincyto more aggressively than it should and symptoms may be similar to infusion reactions. Tell your healthcare provider right away if you develop a fever, chills, wheezing or difficulty breathing, dizziness, headache, low blood pressure, nausea or vomiting, body aches, diarrhea, facial swelling, a skin rash, or feel tired or light-headed.

Neurologic problems. Blincyto may affect your nerves and can cause some serious neurological disorders including a potentially life-threatening neurotoxicity called immune effector cell-associated neurotoxicity syndrome (ICANS). Tell your healthcare provider right away if you experience:

  • seizures
  • difficulty in speaking or slurred speech
  • loss of consciousness
  • trouble sleeping
  • confusion and disorientation
  • loss of balance
  • headache
  • difficulty with facial movements, hearing, vision, or swallowing
  • tremors.

People with Down Syndrome over the age of 10 years may have a higher risk of seizures with Blincyto.

Life-threatening infections that may lead to death. Tell your healthcare provider right away if you develop any signs or symptoms of an infection.

Tumor Lysis Syndrome (TLS) is caused by the fast breakdown of cancer cells. It can be life-threatening
and may lead to death. Tell your healthcare provider right away if you have any symptoms of TLS during treatment with Blincyto, including:

  • nausea and vomiting
  • confusion
  • shortness of breath
  • irregular heartbeat
  • dark or cloudy urine
  • reduced amount of urine
  • unusual tiredness
  • muscle cramps.

Low white blood cell counts (neutropenia) are common with Blincyto treatment and may sometimes be life-threatening. They can increase your risk of infection. Your healthcare provider will do blood tests to check your white blood cell counts during treatment. Tell your healthcare provider right away if you get a fever, chills, tiredness, mouth sores, skin sores, easy bruising, unusual bleeding, pale skin, cold hands or feet, or feel light-headed or short of breath.

Abnormal liver blood tests. Your healthcare provider will do blood tests to check your liver before you start Blincyto and during treatment.

Inflammation of the pancreas (pancreatitis). Pancreatitis may happen in people treated with Blincyto and
corticosteroids. It may be severe and lead to death. Tell your healthcare provider right away if you have severe stomach-area pain that does not go away. The pain may happen with or without nausea and vomiting.

People receiving Blincyto are at risk of seizures or losing consciousness and should not drive or engage in hazardous activities.

Blincyto may harm an unborn baby and should not be taken by females who are pregnant.

Before taking this medicine

You should not use Blincyto if you are allergic to blinatumomab, Blincyto, or any inactive ingredients in the injection.

To make sure Blincyto is safe for you, tell your doctor if you have:

  • nerve problems or a neurologic disorder, such as seizures, confusion, trouble speaking, or problems with balance
  • Down syndrome
  • a history of chemotherapy or radiation treatment to your brain
  • an infection
  • have recently received a vaccine or if you are scheduled for a booster dose
  • are pregnant or plan to become pregnant
  • are breastfeeding.

Pregnancy

Blincyto may harm an unborn baby. If you are able to become pregnant, your healthcare provider should do a pregnancy test before you start treatment with Blincyto. Females who are able to become pregnant should use an effective form of birth control (contraception) during treatment with Blincyto, and for 48 hours after their last dose. Do not use Blincyto if you are pregnant. If you inadvertently become pregnant while receiving Blincyto, tell your healthcare provider right away.

Breastfeeding

It is not known if Blincyto passes into your breast milk. You should not breastfeed while using this medicine and for at least 48 hours after your last dose.

How is Blincyto administered?

Blincyto will be given to you by a continuous intravenous (IV) infusion into your vein using a small portable infusion pump. This means you can still carry out daily activities as normal, although you should be careful not to drive or engage in hazardous tasks while receiving the infusion.

  • One induction treatment cycle is usually 4 weeks (28 days) of continuous infusion followed by 2 weeks (14 days) break without infusion.
  • For the first 3 to 9 days of the first cycle and the first 2 days of the second cycle, you will usually receive this in a hospital under the care of your healthcare provider.
  • For the rest of the cycle, your healthcare provider will decide if you receive your treatment at home or through an outpatient clinic or infusion center.
  • Your healthcare provider will decide the number of treatment cycles of Blincyto but a treatment course for MRD is usually 1 cycle of Blincyto for induction followed by up to 3 additional cycles for consolidation (continued therapy). This usually consists of one IV infusion for 4 weeks (28 days), followed by an 8-week (56 days) break during which you will not receive Blincyto. This is 1 consolidation treatment cycle (84 days).
  • Your healthcare provider may change your dose of Blincyto, delay, or completely stop treatment if you have certain side effects, and do blood tests during treatment to check you for side effects.

Before receiving Blincyto, you will be given a corticosteroid medicine to help reduce infusion reactions.

Before and during treatment, you may be given chemotherapy as an injection into the space that
surrounds the spinal cord and the brain (intrathecal injection) to help prevent central nervous system relapse of ALL.

  • It is very important to keep the area around the IV catheter clean to reduce the risk of getting an infection. Your healthcare provider will show you how to care for your catheter site.

Receiving Blincyto at home

If your healthcare provider has decided you can receive Blincyto at home, your infusion bag will be changed at an outpatient center or by your home healthcare provider.

  • Blincyto is available in 24-hour, 48-hour, and 7-day infusion bags. Your bag will need to be changed every day, every 2 days, or once a week based on what your doctor decides is best for you.
  • Call your doctor if you experience any problems or side effects.
  • Do not change the settings on your infusion pump, even if there is a problem with your pump or your pump alarm sounds. Any changes to your infusion pump settings may cause a dose that is too high or too low to be given.
  • Call your healthcare provider or nurse right away if you have any problems with your pump or your pump alarm sounds.
  • Keep Blincyto out of reach of children or pets in the household.

What happens if I miss a dose?

Call your healthcare provider if you do not receive your IV bags on time or if your home healthcare provider does not change the infusion bag in time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line .

Overdose symptoms may include fever, tremors, and headache.

What should I avoid while using Blincyto?

Do not receive a “live” vaccine while using Blincyto, or you could develop a serious infection. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), and zoster (shingles). Ask your doctor how soon it is safe for you to receive a vaccine after you stop using this medicine.

Avoid driving or hazardous activity until you know how Blincyto will affect you. Blincyto increases your risk of seizures, losing consciousness, and a serious nerve toxicity syndrome called ICANS (see above).

What other drugs will affect Blincyto?

Other drugs may interact with blinatumomab, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.

No formal drug interaction studies have been conducted with Blincyto. The highest drug interaction risk is during the first 9 days of the first cycle and the first 2 days of the second cycle. People receiving medications with a narrow therapeutic index metabolized by the cytochrome p450 system, such as warfarin or cyclosporin should be monitored for increases in side effects and the dosage of the interacting drug adjusted if needed.

No formal drug interaction studies have been conducted with Blincyto, but starting Blincyto treatment causes the short-lived release of cytokines that may suppress CYP450 enzymes and affect medications with a narrow therapeutic index, such as warfarin.

Storage

Intravenous (IV) bags containing Blincyto for infusion will arrive in a special package.

  • Do not open the package.
  • Do not freeze the package.

The package containing Blincyto will be opened by your healthcare provider and stored in the refrigerator at 36°F to 46°F (2°C to 8°C).

Bisoprolol https://drugonomy.com/2026/02/01/bisoprolol/ https://drugonomy.com/2026/02/01/bisoprolol/#respond Sun, 01 Feb 2026 11:10:05 +0000 https://drugonomy.com/?p=11200 What is bisoprolol?

Bisoprolol is a beta-blocker that affects the heart and circulation (blood flow through arteries and veins).

Bisoprolol is used to treat hypertension (high blood pressure).

Bisoprolol may also be used for purposes not listed in this medication guide.

Warnings

Do not skip doses or stop taking bisoprolol without first talking to your doctor. Stopping suddenly may make your condition worse or cause other serious heart problems.

If you need to have any type of surgery, tell the surgeon ahead of time that you are using this medicine.

You should not use bisoprolol if you have a serious heart condition such as “AV block,” severe heart failure, or slow heartbeats that have caused you to faint.

Keep using bisoprolol as directed, even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.

Before taking this medicine

You should not use bisoprolol if you you are allergic to it, or if you have a serious heart condition such as:

  • “AV block”;
  • severe heart failure; or
  • slow heartbeats that have caused you to faint.

To make sure bisoprolol is safe for you, tell your doctor if you have:

  • congestive heart failure or other heart problems;
  • coronary artery disease;
  • circulation problems (such as Peripheral Vascular Disease or Raynaud’s syndrome);
  • asthma, chronic obstructive pulmonary disease (COPD), or other breathing disorder;
  • diabetes (taking bisoprolol can make it harder for you to tell when you have low blood sugar);
  • liver or kidney disease;
  • a thyroid disorder; or
  • a history of allergies.

It is not known whether bisoprolol is harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

It is not known whether bisoprolol passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

Bisoprolol is not approved for use by anyone younger than 18 years old.

How should I take bisoprolol?

Take bisoprolol exactly as it was prescribed for you. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Do not skip doses or stop taking bisoprolol without first talking to your doctor. Stopping suddenly may make your condition worse or cause other serious heart problems.

If you need surgery, tell the surgeon ahead of time that you are using bisoprolol.

Your blood pressure will need to be checked often.

Keep using this medicine as directed, even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medicine for the rest of your life.

Store bisoprolol at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What to avoid

This medicine may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.

Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.

Minimize drinking alcohol. It can increase some of the side effects of bisoprolol.

Bisoprolol side effects

Get emergency medical help if you have signs of an allergic reaction to bisoprolol: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have:

  • shortness of breath (even with mild exertion), swelling, rapid weight gain;
  • slow heart rate;
  • pounding heartbeats or fluttering in your chest;
  • numbness, tingling, or cold feeling in your hands or feet;
  • a light-headed feeling, like you might pass out;
  • eye pain, vision problems; or
  • bronchospasm (wheezing, chest tightness, trouble breathing).

Common bisoprolol side effects may include:

  • headache;
  • feeling tired;
  • sleep problems (insomnia);
  • joint pain;
  • swelling; or
  • cold symptoms such as stuffy nose, runny nose, cough, sore throat.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects.

What other drugs will affect bisoprolol?

Tell your doctor about all your current medicines and any you start or stop using, especially:

  • insulin or oral diabetes medicine;
  • rifampin; or
  • heart or blood pressure medicine–clonidine, digitalis, digoxin, diltiazem, reserpine, or verapamil.

CONTRAINDICATIONS The HalfLytely and Bisacodyl Tablets Bowel Prep Kit is contraindicated in the following conditions: •Known allergies to polyethylene glycol or other components of the kit •Gastrointestinal (GI) obstruction •Bowel perforation •Toxic colitis •Toxic megacolon Toxic megacolon (4)

Warnings and Precautions

There have been reports of generalized tonic-clonic seizures in patients with use of large volume (4 liter) PEG-based colon preparation products in patients with no prior history of seizures. The seizure cases were associated with severe vomiting, excessive beverage consumption and electrolyte abnormalities (for example, hyponatremia, hypokalemia). The neurologic abnormalities resolved with correction of fluid and electrolyte abnormalities. Therefore, HalfLytely and Bisacodyl Tablets Bowel Prep Kit should be used with caution in patients using concomitant medications (such as diuretics) that increase the risk of electrolyte abnormalities or patients with known or suspected hyponatremia. Monitor baseline and post-colonoscopy laboratory tests (sodium, potassium, calcium, creatinine, and BUN) in these patients.

Clinical Studies

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in clinical studies of another drug and may not reflect the rates observed in practice. In a clinical study of HalfLytely and (10 mg vs. 20 mg) Bisacodyl Tablets Bowel Prep Kit multicentered, controlled clinical trials, abdominal pain/cramping, nausea, vomiting and headache were the most common adverse reactions ( 3%) after the administration of HalfLytely and (10 mg or 20 mg) Bisacodyl Tablets Bowel Prep Kit. Less than 1% of patients exposed to HalfLytely and 10 mg Bisacodyl Tablets Bowel Prep Kit reported vomiting and abdominal pain/cramping. The data in reflects exposure in 222 patients to HalfLytely and 10 mg bisacodyl tablets vs. 223 patients exposed to HalfLytely and 20 mg bisacodyl tablets. The HalfLytely and 10 mg Bisacodyl Tablets Bowel Prep Kit population was 20-85 years of age, 46% male, 54% female, 10% African American, 85% Caucasian, 8% Hispanic requiring a colonoscopy. The demographics of the comparator group were similar.

Biotin https://drugonomy.com/2026/02/01/biotin/ https://drugonomy.com/2026/02/01/biotin/#respond Sun, 01 Feb 2026 10:54:58 +0000 https://drugonomy.com/?p=11194 What is biotin?

Biotin, also known as Vitamin B7, is a form of vitamin B found in foods. Biotin helps the body break down fats, carbohydrates, and proteins into energy.

Biotin is likely effective in alternative medicine as an aid in treating or preventing low levels of biotin. Low levels of biotin can be caused by malnutrition, rapid weight loss, long-term tube feeding, and other medical conditions.

Biotin has also been used to treat the symptoms of multiple sclerosis (MS) and seborrhea (in babies). However, research has shown that biotin may not be effective in treating these conditions.

Other uses not proven with research have included treating brittle nails, hair loss, diabetes, nerve pain, depression, and other conditions.

Biotin may also be used in combination with other vitamins in adults and children as a dietary supplement.

It is not certain whether biotin is effective in treating any medical condition. Medicinal use of this product has not been approved by the FDA. Biotin should not be used in place of medication prescribed for you by your doctor.

Biotin is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination.

Biotin may also be used for purposes not listed in this product guide.

Biotin side effects

Get emergency medical help if you have signs of an allergic reaction: hives, difficult breathing, swelling of your face, lips, tongue, or throat.

Common side effects may include diarrhea or respiratory problems.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects.

Warnings

Follow all directions on the product label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Before taking this medicine

You should not use this product if you are allergic to biotin.

Before using biotin, talk to your healthcare provider. Your dose needs may be different if you:

  • have a deficiency of the enzyme called biotinidase;
  • smoke; or
  • kidney disease (or if you are on dialysis).

Ask a doctor before using this product if you are pregnant or breastfeeding.

Do not give any herbal/health supplement to a child without medical advice.

How should I take biotin?

When considering the use of herbal supplements, seek the advice of your doctor. You may also consider consulting a practitioner who is trained in the use of herbal/health supplements.

Biktarvy https://drugonomy.com/2026/02/01/biktarvy/ https://drugonomy.com/2026/02/01/biktarvy/#respond Sun, 01 Feb 2026 10:48:46 +0000 https://drugonomy.com/?p=11190 What is Biktarvy?

Biktarvy is a complete HIV-1 treatment in a once-a-day single tablet that contains the three antiviral medicines bictegravir, emtricitabine, and tenofovir alafenamide.  Biktarvy works by preventing HIV from multiplying in your body, lowering HIV blood levels, and decreasing your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses, such as cancer or severe infections. 

Biktarvy is a complete treatment and should not be used with any other HIV medicines. Human immunodeficiency virus type 1 (HIV-1) is the virus that can cause acquired immune deficiency syndrome (AIDS).

There is no Biktarvy generic available.

Who can take Biktarvy?

Biktarvy is used to treat HIV-1 infection in adults and pediatric patients who weigh at least 14 kg who:

  • have not taken HIV-1 medicine in the past OR
  • to replace their current HIV-1 medicine if they are virologically suppressed (HIV-1 RNA less than 50 copies per mL), on a stable antiretroviral regimen with no history of treatment failure and with no known substitutions associated with resistance to bictegravir or tenofovir.
  • have taken antiretroviral treatment in the past and are not virologically suppressed, with no known or suspected substitutions associated with resistance to the integrase strand inhibitor class, emtricitabine, or tenofovir.

Biktarvy’s FDA approval was first received on February 7, 2018, by Gilead Sciences, Inc. The latest expansion of FDA approval on July 30, 2025, makes Biktarvy a treatment option for patients with HIV who need to restart treatment and are not virologically suppressed.

Biktarvy is also recommended by the CDC as one of the preferred agents for PEP (post-exposure prophylaxis of HIV-1), despite it not being FDA-approved for this purpose. 

How does Biktarvy work?

Biktarvy contains three antiviral active ingredients that prevent HIV replication, which decreases viral load. 

Biktarvy’s mechanism of action is as an integrase strand transfer inhibitor (INSTI) for the active ingredient bictegravir, and as nucleoside reverse transcriptase inhibitors (NRTIs) for the active ingredients emtricitabine and tenofovir alafenamide.
