Ranitidine https://drugonomy.com/2025/08/28/ranitidine/ https://drugonomy.com/2025/08/28/ranitidine/#respond Thu, 28 Aug 2025 21:11:43 +0000 https://medicine-21.com/Drugs/?p=2921 Generic name: ranitidine [ ra-NI-ti-deen ]
Brand name: Zantac
Drug class: H2 antagonists 

What is ranitidine?

Ranitidine was withdrawn from the market in the United States in April 2020.

Ranitidine belongs to a group of drugs called histamine-2 blockers. It works by reducing the amount of acid your stomach produces.

Ranitidine has been used to treat and prevent ulcers in the stomach and intestines. It also was used to treat conditions in which the stomach produces too much acid, such as Zollinger-Ellison syndrome..

Ranitidine was also used to treat gastroesophageal reflux disease (GERD) and other conditions in which acid backs up from the stomach into the esophagus, causing heartburn.

A cancer-causing impurity found in many ranitidine medications may increase to unacceptable levels over time and when ranitidine is stored at high temperatures. As a result, the FDA has asked all makers of ranitidine to withdraw this medicine from the market in the United States.

Warnings

Ranitidine has been withdrawn from the market in the United States. Some of the contents of this leaflet are preserved for historical purposes only.

Using ranitidine may increase your risk of developing pneumonia. Symptoms of pneumonia include chest pain, fever, feeling short of breath, and coughing up green or yellow mucus. Talk with your doctor about your specific risk of developing pneumonia.

Do not use this medication if you are allergic to ranitidine.

Ask a doctor or pharmacist if it is safe for you to take this medicine if you have kidney disease, liver disease, or porphyria.

Rapamune https://drugonomy.com/2025/08/28/rapamune/ https://drugonomy.com/2025/08/28/rapamune/#respond Thu, 28 Aug 2025 21:08:10 +0000 https://medicine-21.com/Drugs/?p=2911 Generic name: sirolimus [ sih-RO-lim-us ]
Drug classes: MTOR inhibitors Selective immunosuppressants 

What is Rapamune?

Rapamune weakens your body’s immune system, to help keep it from “rejecting” a transplanted organ such as a kidney. Organ rejection happens when the immune system treats the new organ as an invader and attacks it.

Rapamune is a prescription medicine used to prevent rejection (anti-rejection medicine) in people 13 years of age and older who have received a kidney transplant. Rejection is when your body’s immune system recognizes the new organ as a “foreign” threat and attacks it. Rapamune is used with other medicines called cyclosporine (Gengraf, Neoral, Sandimmune), and corticosteroids.

Rapamune is also given without other medicines to treat a rare lung disorder called lymphangioleiomyomatosis (LAM). LAM affects predominantly women of childbearing age. This disorder happens mostly in women and causes lung tumors that are not cancerous but can affect breathing.

Warnings

You should not use Rapamune if you have ever had a lung transplant or liver transplant.

Rapamune may cause your body to overproduce white blood cells. This can lead to cancer, severe brain infection causing disability or death, or a viral infection causing kidney transplant failure.

Call your doctor right away if you have: fever, flu symptoms, burning when you urinate, a new skin lesion, any change in your mental state, decreased vision, weakness on one side of your body, problems with speech or walking, or pain around your transplant.

Before taking this medicine

You should not use Rapamune if you are allergic to sirolimus, or if you have ever had a lung transplant or liver transplant.

Talk with your doctor about the risks and benefits of using this medicine. Rapamune can affect your immune system, and may cause overproduction of certain white blood cells. This can lead to cancer, severe brain infection causing disability or death, or a viral infection causing kidney transplant failure.

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

  • high cholesterol or triglycerides;
  • cytomegalovirus (CMV);
  • liver disease; or
  • a family history of skin cancer (melanoma).

Do not use Rapamune if you are pregnant. Use effective birth control to prevent pregnancy while you are taking this medicine, and for at least 12 weeks after your last dose.

You should not breast-feed while using this medicine.

Rapamune should not be given to a child younger than 13 years old.

How should I take Rapamune?

Take Rapamune 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.

Rapamune is usually taken once a day. If you also take cyclosporine, take it at least 4 hours before you take this medicine.

You may take Rapamune with or without food, but take it the same way every time.

Do not crush, chew, or break a Rapamune tablet. Tell your doctor if you have trouble swallowing the tablet whole.

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

Rapamune oral liquid must be mixed only with water or orange juice, no other juices or liquids. Measure the liquid carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Sirolimus can increase your risk of infection by changing the way your immune system works. You will need frequent medical tests. Your dosing schedule may be delayed based on the results of these tests.

You should not stop using Rapamune without your doctor’s advice. Stopping suddenly could make your condition worse.

Store the tablets at room temperature, away from heat, moisture, and light.

Store the oral liquid in the refrigerator. Do not freeze. You may notice a slight haze to the liquid. This haze should disappear when the liquid reaches room temperature.

If you are using Rapamune oral liquid with a disposable syringe, you may store a loaded syringe in the carrying case provided. Keep the case at room temperature and use the medicine within 24 hours. Use a disposable syringe only once and then throw it away.

Dosing information

Usual Adult Dose of Rapamune for Organ Transplant — Rejection Prophylaxis:

Ravulizumab https://drugonomy.com/2025/08/28/ravulizumab/ https://drugonomy.com/2025/08/28/ravulizumab/#respond Thu, 28 Aug 2025 21:06:05 +0000 https://medicine-21.com/Drugs/?p=2905 Pronunciation: RAV-ue-LIZ-ue-mab
Generic name: ravulizumab-cwvz
Brand name: Ultomiris
Dosage form: intravenous injection (10 mg/mL, 100mg/mL)
Drug class: Selective immunosuppressants 

What is ravulizumab-cwvz?

Ravulizumab-cwvz is a prescription medication used to treat myasthenia gravis (gMG), hemolytic uremic syndrome (aHUS), paroxysmal nocturnal hemoglobinuria (PNH), and neuromyelitis optica spectrum disorder (NMOSD) in certain patients. Ravulizumab helps regulate the immune system to prevent it from harming cells, which improves symptoms of these conditions.

Ravulizumab is given as an intravenous (IV) infusion by a healthcare provider. After the initial loading doses, ravulizumab is administered as a maintenance dose every 4 to 8 weeks

Ravulizumab brand name is Ultomiris by Alexion Pharmaceuticals, Inc.

Ravulizumab FDA approval was granted on December 21, 2018, for paroxysmal nocturnal hemoglobinuria. Since the Ravulizumab FDA approval for myasthenia gravis (general) was granted and several other conditions.

What is ravulizumab used for?

Ravulizumab FDA-approved indications are:

  • generalized myasthenia gravis (gMG) in adults who are anti-acetylcholine receptor (AChR) antibody-positive
  • paroxysmal nocturnal hemoglobinuria (PNH) in adults and children aged one month and older
  • atypical hemolytic uremic syndrome (aHUS) to inhibit complement-mediated thrombotic microangiopathy (TMA) in adults and children aged one month and older, with (does not include Shiga toxin E. coli-related hemolytic uremic syndrome [STEC-HUS])
  • neuromyelitis optica spectrum disorder (NMOSD) in adults who are anti-aquaporin-4 (AQP4) antibody positive.

​​How does ravulizumab work?

Ravulizumab mechanism of action is as a monoclonal antibody complement inhibitor (C5).

Ravulizumab is a monoclonal antibody that blocks a part of the immune system called the complement system. It specifically targets and inhibits the C5 protein, which plays a key role in immune responses. Ravulizumab binds to the C5 protein and prevents it from being activated. This stops the immune system from mistakenly attacking healthy cells, which helps reduce symptoms and prevent disease progression.

Monoclonal antibodies are lab-made proteins designed to attach to specific targets, ravulizumab targets C5. The precise way Ultomiris infusion works is unknown, but it is thought to be due to a reduction or inhibition of C5b-9 deposition. 

Ravulizumab Clinical Trial Results

Improvement in Myasthenia Gravis (gMG) Symptoms

Ravulizumab has shown to reduce symptoms of generalized myasthenia gravis, as measured by the Myasthenia Gravis Activities of Daily Living (MG-ADL) score. This scale ranges from 0 to 24, with higher scores indicating more severe impairment.

Key Findings from Clinical Trial ALXN1210-MG-306 (NCT03920293)

At 26 weeks, patients treated with ravulizumab showed significant improvement:

  • 30% of patients experienced at least a 5-point improvement in MG-ADL (vs. 11.3% in placebo)
  • 56.7% of patients had at least a 3-point improvement in MG-ADL (vs. 34.1% in placebo)
  • The least squares (LS) mean MG-ADL score improved by -3.1 (vs. -1.4 in placebo).

Additional Clinical Trial Data

Clinical trial results of ravulizumab cwvz in hemolytic uremic syndrome (aHUS), paroxysmal nocturnal hemoglobinuria (PNH), and neuromyelitis optica spectrum disorder (NMOSD) are available in the Ravulizumab Package Insert – Clinical Studies.

Ravulizumab side effects

Common ravulizumab side effects

Common side effects of ravulizumab in gMG may include:

  • Diarrhea (15%)
  • high blood pressure (14%)
  • Stomach pain (6%)
  • Upper respiratory tract infection (14%)
  • Urinary tract infection (6%)
  • Back Pain (8%)
  • Dizziness (9%).

These side effects occurred in 5% or more of generalized myasthenia gravis patients treated with ravulizumab in the Clinical Trial ALXN1210-MG-306.

Side effects vary depending on the condition being treated and the dose given.

Serious ravulizumab side effects

Get emergency medical help if you have signs of an allergic reaction with symptoms of hives, difficulty breathing, or 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.

Ravulizumab for Myasthenia Gravis

Understanding Myasthenia Gravis

Myasthenia gravis (MG) is a neuromuscular disorder caused by disrupted nerve-to-muscle communication at the neuromuscular junction. This occurs when the immune system attacks healthy cells or proteins needed for normal function, which prevents proper muscle activation.

If myasthenia gravis is AChR antibody-positive, the condition is specifically caused by antibodies targeting acetylcholine receptors.

How Ravulizumab Works for Myasthenia Gravis

Ravulizumab is a complement inhibitor that blocks complement, part of the immune system, responsible for damaging the neuromuscular junction. By reducing this immune attack, Ravulizumab helps improve muscle function and symptoms in people with myasthenia gravis.

Ravulizumab REMS Program (Ultomiris REMS)

Due to the risk of serious meningococcal infections, Ravulizumab is only available through a restricted Risk Evaluation and Mitigation Strategy (REMS) program known as Ultomiris REMS. This program ensures patient safety by reducing the risk of life-threatening infections.

Steps Required Before Starting Ravulizumab (Ultomiris REMS Program)

Before receiving Ravulizumab, your doctor must:

  • Enroll you in the REMS program.
  • Explain the risks of meningococcal infections.
  • Provide information on early symptoms of infection and the need for immediate medical attention.
  • Confirm meningococcal vaccination and, if needed, provide preventive antibiotics if treatment must start before full vaccination.
  • Give you a Patient Safety Card outlining the risk of infection.

 Important: Meningococcal vaccines do not prevent all infections. Seek emergency medical care if you experience any of the following symptoms:

Signs of a Serious Meningococcal Infection

  • High fever or fever with rapid heart rate
  • Severe headache with fever
  • Confusion or disorientation
  • Muscle aches with flu-like symptoms
  • Fever with a rash
  • Headache with nausea or vomiting
  • Stiff neck or back
  • Light sensitivity (photosensitivity)

Warnings

Ravulizumab infusion affects your immune system. You may get infections more easily, even serious or fatal infections such as meningitis. Call your doctor if you have a fever, flu-like symptoms, muscle pain, headache, confusion, neck or back stiffness, vomiting, rash, or if your eyes are more sensitive to light.

You will need to receive certain vaccinations, including vaccinations to protect against meningococcal disease, at least 2 weeks before you start using ravulizumab unless the risks of delaying ravulizumab outweigh the risks of a serious infection.

Ravulizumab comes with a Patient Safety Card listing symptoms of meningococcal infection. Keep this card with you at all times while using ravulizumab and for at least 8 months after your last dose. Your infection risk could last for several months after you stop using this medicine.

Some people may have an increased risk of gonorrhea (a sexually transmitted disease) while using this medicine. Talk with your doctor about safe ways to keep from getting an infection during sex.

This medicine should not be started in patients with unresolved serious Neisseria meningitidis infection.

Rebif https://drugonomy.com/2025/08/28/rebif/ https://drugonomy.com/2025/08/28/rebif/#respond Thu, 28 Aug 2025 21:03:56 +0000 https://medicine-21.com/Drugs/?p=2901 Pronunciation: re-bif
Generic name: interferon beta-1a
Other brand names of interferon beta-1a include: Rebif, Rebif Rebidose
Dosage form: single-dose prefilled syringe for subcutaneous use, single-dose prefilled autoinjector for subcutaneous use
Drug class: Interferons 

What is Rebif?

Rebif is used to treat relapsing forms of multiple sclerosis (MS) in adults, including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease.

  • The generic name for Rebif is interferon beta-1a.
  • Rebif is injected under the skin (subcutaneously), usually 3 times a week, such as on a Monday, Wednesday, and Friday.

Rebif’s mechanism of action resembles that of interferons which are proteins naturally produced by our immune system that help regulate the body’s immune response and fight viral infections. Rebif is a man-made form of interferon that works in the same way, binding to specific receptors on cell surfaces and decreasing the activity of immune cells that attack the myelin sheath, reducing inflammation in the central nervous system, and helping to suppress the autoimmune response that characterizes MS.

Rebif belongs to the drug class called interferons. It may also be called an immunomodulator. Rebif will not cure MS, it will only decrease the frequency of relapse symptoms.

Rebif gained FDA approval on March 7, 2002. Another brand of interferon beta-1a given intramuscularly (into a muscle) called Avonex, was the first interferon beta-1a to be approved (May 17, 1996). There is no Rebif generic.

Rebif side effects

The most common side effects of Rebif are:

  • flu-like symptoms such as:
    • muscle aches
    • fever
    • tiredness
    • chills.
  • stomach pain
  • changes in your liver tests.

Serious side effects and warnings

Rebif can cause the following serious side effects.

Behavioral health problems including depression and suicidal thoughts. You may have mood problems while taking Rebif, for example, depression (feeling hopeless or feeling bad about yourself), or thoughts of hurting yourself or suicide. Contact your healthcare provider immediately.

Liver problems or liver failure has been reported in people taking Rebif. Contact your healthcare provider immediately if you develop any of the following symptoms:

  • nausea
  • loss of appetite
  • tiredness
  • dark-colored urine and pale stools
  • yellowing of your skin or the white part of your eye
  • bleeding more easily than normal
  • confusion
  • sleepiness.

Rebif may cause serious allergic and skin reactions. Contact your healthcare provider or seek emergency medical attention if you develop any of the following symptoms:

  • itching
  • swelling of your face, eyes, lips, tongue or throat
  • trouble breathing
  • anxiousness
  • feeling faint
  • skin rash, hives, sores in your mouth, or skin blisters and peels.

Injection site problems. Rebif may cause redness, pain, itching, or swelling at the place where your injection was given. Call your healthcare provider immediately if an injection site becomes swollen and painful or the area looks infected. You may have a skin infection or an area of severe skin damage (necrosis) requiring treatment by a healthcare provider.

Blood problems. Rebif can affect your bone marrow and cause low red and white blood cell, and platelet counts. In some people, these blood cell counts may fall to dangerously low levels. If your blood cell counts become very low, you can get infections and problems with bleeding and bruising. Your healthcare provider may ask you to have regular blood tests to check for blood problems.

Pulmonary arterial hypertension. Pulmonary arterial hypertension (high blood pressure in the arteries of the lungs) can occur with interferon beta products, including Rebif. Symptoms may include new fatigue or shortness of breath. Contact your healthcare provider right away if you develop these symptoms.

Thrombotic microangiopathy (TMA). TMA is a condition that involves injury to the smallest blood vessels in your body and this has been reported with Rebif. TMA can also cause injury to your red blood cells (the cells that carry oxygen to your organs and tissues) and your platelets (cells that help your blood clot) and can sometimes lead to death. Your healthcare provider may tell you to stop taking Rebif if you develop TMA.

Seizures. Some people have had seizures while taking Rebif.

Autoimmune diseases. Problems with easy bleeding or bruising (idiopathic thrombocytopenia), thyroid gland problems (hyperthyroidism and hypothyroidism), and autoimmune hepatitis have happened in some people who use Rebif.

Eye Disorders: Retinal disorders (such as retinopathy, cotton wool spots, or obstruction of
the retinal artery or vein) have been reported with Rebif. See your healthcare provider immediately if you have any changes in your vision or eye pain.

During your treatment with Rebif see your healthcare provider regularly and have regular blood tests to check for side effects.

Tell your healthcare provider if you have any side effect that bothers you or does not go away. These are not all the possible side effects of Rebif. For more information, ask your healthcare provider or pharmacist. Call your doctor for medical advice about side effects.

Before taking

Do not take Rebif if you are allergic to interferon beta-1a, human albumin, Rebif, Avonex, or any inactive ingredients in the injection (see below for a list of inactive ingredients).

Before you take Rebif, tell your healthcare provider if you have or have had any of the following conditions:

  • mental illness, including depression and suicidal behavior
  • liver problems
  • bleeding problems or blood clots
  • low blood cell counts
  • seizures (epilepsy)
  • thyroid problems
  • drink alcohol
  • you are pregnant or plan to become pregnant
  • you are breastfeeding or plan to breastfeed.

Pregnancy

It is not known if Rebif can harm your unborn baby.

Breastfeeding

Rebif may pass into your breast milk. Talk with your healthcare provider about the best way to feed your baby while taking this medicine.

How should I use Rebif?

See the Instructions for Use that come with the Rebif Package Insert.

  • Your healthcare provider should show you how to prepare, measure, and inject your dose of Rebif before you use it for the first time.

How to inject Rebif for subcutaneous use

Rebif is given by injection under the skin (subcutaneous injection) on the same 3 days a week, for example, Monday, Wednesday, and Friday.

  • Your injections should be at least 48 hours apart.
  • Try to inject Rebif at the same time the three days that you have chosen to inject it (for example, always around 10am on Monday, Wednesday, and Friday).
  • The best sites for giving yourself an injection are those areas with a layer of fat between the skin and muscle, like your thigh, the outer surface of your upper arm, your stomach or buttocks.
    • Do not use the area near your waistline or within 2 inches of your navel. If you are very thin, use only the thigh or outer surface of the arm for the injection.
  • Inject Rebif exactly as your healthcare provider tells you.

Your healthcare provider will tell you how much Rebif to inject and may change the dose based on how your body responds. 

  • Do not change your dose unless your healthcare provider tells you to.
  • Change (rotate) the injection site you choose with each injection. This will help decrease the chance that you will have an injection site reaction.
  • Do not inject Rebif into an area of the body where the skin is irritated, reddened, bruised, infected, or scarred in any way.

Rebif comes as a:

  • prefilled syringe
  • single-use prefilled autoinjector (Rebif Rebidose).

Your healthcare provider will decide which is best for you. Always use a new, unopened, prefilled syringe or autoinjector for each injection. Do not reuse prefilled syringes or autoinjectors.

Rebif dosing information

The recommended dose of Rebif for MS is either 22 micrograms or 44 micrograms injected subcutaneously, 3 times a week.

Titration: Generally, the starting dose should be 20% of the prescribed dose three times per week, and increased over 4 weeks to the targeted recommended dose of either 22 micrograms or 44 micrograms injected subcutaneously three times per week. Your healthcare provider will calculate this dose for you.

Pain and/or fever-relieving medicines on treatment days may help reduce side effects such as flu-like symptoms.

What other drugs will affect Rebif?

Tell your healthcare provider about all medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

Rebif and other medicines may affect each other causing side effects. Ask your healthcare provider or pharmacist for a list of these medicines, if you are not sure.

Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.

Storage

Store Rebif in the refrigerator between 36°F to 46°F (2°C to 8°C).

Do not freeze Rebif.

If you cannot refrigerate your Rebif pen or autoinjector, you can store it at temperatures above 36°F and below 77°F (2°C to 25°C) for up to 30 days.

Keep Rebif away from heat and light.

Reclast https://drugonomy.com/2025/08/28/reclast/ https://drugonomy.com/2025/08/28/reclast/#respond Thu, 28 Aug 2025 21:01:00 +0000 https://medicine-21.com/Drugs/?p=2894 Generic name: zoledronic acid [ ZOE-le-DRON-ik-AS-id ]
Drug class: Bisphosphonates 

What is Reclast?

Reclast (sometimes called zoledronate) is a bisphosphonate medicine that alters bone formation and breakdown in the body. This can slow bone loss and may help prevent bone fractures.

Reclast is used to treat or prevent osteoporosis caused by menopause, or steroid use. This medicine also increases bone mass in men with osteoporosis. Reclast is for use when you have a high risk of bone fracture.

Reclast is also used to treat Paget’s disease of bone.

Zometa is another brand of zoledronic acid used to treat high blood levels of calcium caused by cancer (also called hypercalcemia of malignancy). This medicine also treats multiple myeloma (a type of bone marrow cancer) or bone cancer that has spread from elsewhere in the body. You should not use Reclast and Zometa at the same time.

Warnings

Zoledronic acid may harm an unborn baby. Do not use Reclast if you are pregnant. Use effective birth control, and ask your doctor how long to prevent pregnancy after you stop this medicine.

Reclast can cause serious kidney problems, especially if you are dehydrated, if you take diuretic medicine, or if you already have kidney disease. Call your doctor if you urinate less than usual, if you have swelling in your feet or ankles, or if you feel tired or short of breath.

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.

Your doctor may recommend you have a dental exam for preventive tooth and gum care before you start your treatment with zoledronic acid. This is especially important if you have cancer, if you are undergoing chemotherapy or using steroids, or if you have poor dental health.

Some people using medicines similar to Reclast have developed bone loss in the jaw, also called osteonecrosis of the jaw. Symptoms of this condition may include jaw pain, swelling, numbness, loose teeth, gum infection, or slow healing after injury or surgery involving the gums. You may be more likely to develop osteonecrosis of the jaw if you have cancer or have been treated with chemotherapy, radiation, or steroids. Other conditions associated with osteonecrosis of the jaw include blood clotting disorders, anemia (low red blood cells), and pre-existing dental problems.

Before taking this medicine

You should not be treated with Reclast if you are allergic to zoledronic acid.

You also should not receive Reclast if you have:

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

You should not be treated with Reclast if are currently using any other bisphosphonate (such as alendronate, etidronate, ibandronate, pamidronate, risedronate, or tiludronate).

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

  • kidney disease;
  • hypocalcemia;
  • thyroid or parathyroid surgery;
  • surgery to remove part of your intestine;
  • asthma caused by taking aspirin;
  • any condition that makes it hard for your body to absorb nutrients from food (malabsorption);
  • a dental problem (you may need a dental exam before you receive Reclast);
  • if you are dehydrated; or
  • if you take a diuretic or “water pill”.

Zoledronic acid can cause serious kidney problems, especially if you are dehydrated, if you take diuretic medicine, or if you already have kidney disease.

This medicine may cause jaw bone problems (osteonecrosis). The risk is highest in people with cancer, blood cell disorders, pre-existing dental problems, or people treated with steroids, chemotherapy, or radiation. Ask your doctor about your own risk.

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

Do not use Reclast if you are pregnant. Zoledronic acid may harm an unborn baby or cause birth defects. Zoledronic acid can remain in your body for weeks or years after your last dose. Use effective birth control to prevent pregnancy while using this medicine. Talk with your doctor about the need to prevent pregnancy after you stop using Reclast.

This medicine may affect fertility (ability to have children) in women. However, it is important to use birth control to prevent pregnancy because zoledronic acid can harm an unborn baby.

You should not breastfeed while using Reclast.

How is Reclast given?

Reclast is given as an infusion into a vein. A healthcare provider will give you this injection.

Reclast is sometimes given as a single dose only one time. It may also be given once every 1 or 2 years. How often you receive Reclast will depend on why you are using this medicine. Follow your doctor’s instructions.

Drink at least 2 glasses of water within a few hours before your injection to keep from getting dehydrated.

You may need frequent medical tests to help your doctor determine how long to treat you with Reclast. Your kidney function may also need to be checked.

Pay special attention to your dental hygiene while using Reclast. Brush and floss your teeth regularly. If you need to have any dental work (especially surgery), tell the dentist ahead of time that you are using Reclast.

Reclast is only part of a complete program of treatment that may also include diet changes and taking calcium and vitamin supplements. Follow your doctor’s instructions very closely.

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

Reglan https://drugonomy.com/2025/08/28/reglan/ https://drugonomy.com/2025/08/28/reglan/#respond Thu, 28 Aug 2025 16:09:27 +0000 https://medicine-21.com/Drugs/?p=2812 Generic name: metoclopramide [ MET-oh-KLOE-pra-mide ]
Drug classes: GI stimulants Miscellaneous antiemetics 

What is Reglan?

Reglan increases muscle contractions in the upper digestive tract. This speeds up the rate at which the stomach empties into the intestines and may help with nausea.

Reglan is used for 4 to 12 weeks to treat heartburn caused by gastroesophageal reflux in people who have used other medications without relief.

Reglan is also used to treat gastroparesis (slow stomach emptying) in people with diabetes, which can cause heartburn and stomach discomfort after meals.

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

Warnings

Do not use Reglan if you’ve ever had muscle movement problems after using metoclopramide or similar medicines, or if you’ve had a movement disorder called tardive dyskinesia. You also should not use this medicine if you’ve had stomach or intestinal problems (a blockage, bleeding, or a hole or tear), epilepsy or other seizure disorder, or an adrenal gland tumor (pheochromocytoma).

NEVER USE METOCLOPRAMIDE IN LARGER AMOUNTS THAN RECOMMENDED, OR FOR LONGER THAN 12 WEEKS. High doses or long-term use can cause a serious movement disorder that may not be reversible. The longer you use metoclopramide, the more likely you are to develop this movement disorder. The risk of this side effect is higher in diabetics and older adults (especially women).

Before you take Reglan, tell your doctor if you have kidney or liver disease, congestive heart failure, high blood pressure, diabetes, Parkinson’s disease, or a history of depression.

Do not drink alcohol. It can increase some of the side effects of metoclopramide.

Stop using Reglan and call your doctor at once if you have tremors or uncontrolled muscle movements, fever, stiff muscles, confusion, sweating, fast or uneven heartbeats, rapid breathing, depressed mood, thoughts of suicide or hurting yourself, hallucinations, anxiety, agitation, seizure, or jaundice (yellowing of your skin or eyes).

Before taking this medicine

You should not use Reglan if you are allergic to metoclopramide, or if you have:

  • tardive dyskinesia (a disorder of involuntary movements);
  • stomach or intestinal problems such as a blockage, bleeding, or perforation (a hole or tear in your stomach or intestines);
  • epilepsy or other seizure disorder;
  • an adrenal gland tumor (pheochromocytoma); or
  • if you’ve ever had muscle movement problems after using metoclopramide or similar medicines.

Tell your doctor if you have ever had:

  • liver or kidney disease;
  • problems with muscle movements;
  • congestive heart failure or a heart rhythm disorder;
  • high blood pressure;
  • seizures;
  • breast cancer;
  • Parkinson’s disease;
  • diabetes; or
  • depression or mental illness.

Tell your doctor if you are pregnant before taking metoclopramide.

It may not be safe to breast-feed a baby while you are using this medicine. Ask your doctor about any risks.

Reglan is not FDA-approved for use by anyone younger than 18 years old.

How should I use Reglan?

Take Reglan exactly as prescribed by your doctor. Follow the directions on your prescription label and read all medication guides. Use the medicine exactly as directed.

Reglan should be taken for only 4 to 12 weeks.

NEVER USE REGLAN IN LARGER AMOUNTS THAN RECOMMENDED, OR FOR LONGER THAN 12 WEEKS. High doses or long-term use of metoclopramide can cause a serious movement disorder that may not be reversible. The longer you use metoclopramide, the more likely you are to develop this movement disorder. The risk of this side effect is higher in diabetics and older adults (especially women).

Reglan is usually taken 30 minutes before meals and at bedtime, or only with meals that usually cause heartburn. Follow your doctor’s dosing instructions very carefully.

Do not use two different forms of metoclopramide (such as tablets and oral syrup) at the same time.

Store at room temperature in a tightly-closed container, away from moisture and heat. Keep the bottle tightly closed.

After you stop taking Reglan, you may have unpleasant withdrawal symptoms such as headache, dizziness, or nervousness.

Dosing information

Usual Adult Dose of Reglan for Gastroesophageal Reflux Disease:

Oral: 10 to 15 mg up to 4 times a day 30 minutes before meals and at bedtime, depending upon symptoms being treated and clinical response. Therapy should not exceed 12 weeks.

Usual Adult Dose of Reglan for Gastroparesis:

During the earliest manifestations of diabetic gastric stasis, oral administration may be initiated. If severe symptoms are present, therapy should begin with IM or IV administration for up to 10 days until symptoms subside at which time the patient can be switched to oral therapy. Since diabetic gastric stasis is often recurrent, therapy should be reinstituted at the earliest manifestation.

Oral: 10 mg 4 times daily, 30 minutes before meals and at bedtime, for 2 to 8 weeks depending on clinical response.

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 . Overdose symptoms may include drowsiness, confusion, or uncontrolled muscle movements.

What to avoid

Drinking alcohol with this medicine can cause side effects.

Avoid driving or hazardous activity until you know how this medicine will affect you. Your reactions could be impaired.

Do not take Reglan with other medications that increase the risk of experiencing extrapyramidal reactions (eg, spasms, muscle contractions, jerky/rigid movements).

Drug class: Nonsteroidal anti-inflammatory drugs 

What is Relafen?

Relafen is a nonsteroidal anti-inflammatory drug (NSAID). Nabumetone works by reducing hormones that cause inflammation and pain in the body.

Relafen is used to relieve the symptoms of rheumatoid arthritis or osteoarthritis.

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

Warnings

Relafen can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).

Relafen may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using Relafen, especially in older adults.

Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds.

Do not use any other over-the-counter cold, allergy, or pain medication without first asking your doctor or pharmacist. Many medicines available over the counter contain aspirin or other medicines similar to Relafen (such as ibuprofen, ketoprofen, or naproxen). If you take certain products together you may accidentally take too much of this type of medication. Read the label of any other medicine you are using to see if it contains aspirin, ibuprofen, ketoprofen, or naproxen. Do not drink alcohol while taking Relafen. Alcohol can increase the risk of stomach bleeding caused by nabumetone. Avoid exposure to sunlight or artificial UV rays (sunlamps or tanning beds). Relafen can make your skin more sensitive to sunlight and sunburn may result.

Before taking this medicine

Relafen can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Even people without heart disease or risk factors could have a stroke or heart attack while taking this medicine.

Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).

Relafen may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using Relafen, especially in older adults.

You should not use Relafen if you are allergic to nabumetone, or if you have ever had an asthma attack or severe allergic reaction after taking aspirin or an NSAID.

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

  • heart disease, high blood pressure, high cholesterol, diabetes, or if you smoke;
  • a heart attack, stroke, or blood clot;
  • stomach ulcers or bleeding;
  • asthma;
  • liver or kidney disease; or
  • fluid retention.

If you are pregnant, you should not take Relafen unless your doctor tells you to. Taking a NSAID during the last 20 weeks of pregnancy can cause serious heart or kidney problems in the unborn baby and possible complications with your pregnancy.

Relafen is not FDA-approved for use by anyone younger than 18 years old.

How should I take Relafen?

Take Relafen 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 take this medicine in larger amounts or for longer than recommended. Use the lowest dose that is effective in treating your condition.

You may take Relafen with or without food.

If you use this medicine long-term, you may need frequent medical tests.

Relugolix https://drugonomy.com/2025/08/28/relugolix/ https://drugonomy.com/2025/08/28/relugolix/#respond Thu, 28 Aug 2025 15:57:58 +0000 https://medicine-21.com/Drugs/?p=2806 Generic name: relugolix [ REL-ue-GOE-lix ]
Brand name: Orgovyx
Dosage form: oral tablet (120 mg)
Drug class: Gonadotropin-releasing hormone antagonists 

What is relugolix?

Relugolix is a prescription medicine used to treat advanced prostate cancer (cancer that begins in the prostate [a male reproductive gland]) in adult men. Relugolix belongs to a class of medications called gonadotropin-releasing hormone (GnRH) receptor antagonists.

Relugolix tablets work by decreasing the amount of testosterone (a male hormone) produced by the body. This may slow or stop the spread of prostate cancer cells that need testosterone to grow.

Warnings

Relugolix may decrease fertility in men. Talk to your doctor about the risks.

Relugolix is intended only for use in men. This medicine is not intended for use alone in women, but can be used in combination with other medications for other uses. If you are a male and your female partner can become pregnant, you should use effective contraception during treatment and for 2 weeks after the last dose. Relugolix may harm the fetus.

Tell your doctor if you or anyone in your family has or has ever had long QT syndrome (a rare heart problem that may cause irregular heartbeat, fainting, or sudden death). Also, tell your doctor if you have or have ever had an electrolyte imbalance in your blood, heart failure, diabetes, high triglycerides (fatty substances in the blood), anemia, or liver problems.

Tell your doctor and pharmacist if you are allergic to relugolix, any other medications, or any of the ingredients in the tablets. Ask your pharmacist for a list of the ingredients.

Before taking this medicine

You should not use relugolix if you are allergic to it, or if you have:

  • heart problems; or
  • long QT syndrome (in you or a family member).

Relugolix can harm an unborn baby and cause loss of pregnancy (miscarriage).

  • If you are a man, use birth control if your sex partner is able to get pregnant. Keep using birth control for at least 2 weeks after your last dose.
  • Tell your doctor if your partner is pregnant or plans to get pregnant.

It may be harder for you to get a woman pregnant while you are using this medicine. You should still use birth control to prevent pregnancy because the medicine can harm an unborn baby.

How should I take relugolix?

Take relugolix tablets 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.

Relugolix is usually taken as 3 tablets the first day, followed by 1 tablet per day.

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

Swallow the tablet whole and do not crush, chew, or break it.

You will need frequent medical tests. Your heart function may need to be checked using an electrocardiogram or ECG (sometimes called an EKG).

Your doctor will determine how long to treat you with relugolix. Do not change your dose or stop using this medicine without your doctor’s advice.

Store tightly closed at room temperature, away from moisture and heat. Keep the tablets in their original container, along with the packet or canister of moisture-absorbing preservative.

Do not keep leftover medicine. Ask your pharmacist about a drug take-back program. You may also mix the leftover medicine with cat litter or coffee grounds in a sealed plastic bag and throw the bag in the trash. Do not flush down the toilet.

Use: For the treatment of adult patients with advanced prostate cancer

What other drugs will affect relugolix?

Sometimes it is not safe to use certain medicines at the same time. Some drugs can affect your blood levels of other drugs you use, which may increase side effects or make the medicines less effective.

Relugolix can cause a serious heart problem. Your risk may be higher if you also use certain other medicines for infections, asthma, heart problems, high blood pressure, depression, mental illness, cancer, malaria, or HIV.

Certain other drugs should not be used within 6 hours after you take relugolix. Your dose should be taken first, before other medicines. Carefully follow your doctor’s instructions about how to schedule the doses of all your medicines.

Many drugs can interact with relugolix. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed here. Tell your doctor about all other medicines you use.

What happens if I miss a dose?

Use the medicine as soon as you can, but skip the missed dose if you are more than 12 hours late for the dose. Do not use two doses at one time.

Remicade https://drugonomy.com/2025/08/28/remicade/ https://drugonomy.com/2025/08/28/remicade/#respond Thu, 28 Aug 2025 15:53:40 +0000 https://medicine-21.com/Drugs/?p=2801 Generic name: infliximab [ in-FLIX-ih-mab ]
Drug classes: Antirheumatics TNF alfa inhibitors 

What is Remicade?

Remicade reduces the effects of a substance in the body that can cause inflammation.

Remicade is used to treat rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis and severe or disabling plaque psoriasis in adults.

Remicade is also used to treat ulcerative colitis and Crohn’s disease in adults and children at least 6 years old.

Infliximab is often used when other medicines have not been effective.

Warnings

You should not use Remicade if you are allergic to infliximab, or if you are also being treated with anakinra (Kineret) or abatacept (Orencia).

Using Remicade may increase your risk of developing certain types of cancer, including a rare fast-growing type of lymphoma that can be fatal. Ask your doctor about your specific risk.

Remicade affects your immune system. You may get infections more easily, even serious or fatal infections. Before you start using Remicade, your doctor may perform tests to make sure you do not have certain infections. Call your doctor if you have a fever, tiredness, flu symptoms, cough, or skin pain.

Before taking this medicine

Tell your doctor if you have ever had tuberculosis (TB), or anyone in your household has tuberculosis. Also tell your doctor if you have recently traveled. Tuberculosis and some fungal infections are more common in certain parts of the world, and you may have been exposed during travel.

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

  • heart failure or other heart problems;
  • an active infection (fever, cough, flu symptoms, open sores or skin wounds);
  • diabetes;
  • liver failure, hepatitis B, or other liver problems;
  • chronic obstructive pulmonary disease (COPD);
  • heart problems;
  • cancer;
  • a weak immune system;
  • seizures;
  • numbness or tingling anywhere in your body;
  • a nerve-muscle disorder, such as multiple sclerosis or Guillain-Barré syndrome;
  • phototherapy for psoriasis;
  • vaccination with BCG (Bacille Calmette-Guérin); or
  • if you are scheduled to receive any vaccines.

Make sure your child is current on all vaccines before he or she starts treatment with Remicade.

Remicade may cause a rare type of lymphoma (cancer) of the liver, spleen, and bone marrow that can be fatal. This has occurred mainly in teenagers and young men with Crohn’s disease or ulcerative colitis. However, anyone with an inflammatory autoimmune disorder may have a higher risk of lymphoma. Talk with your doctor about your own risk.

Remicade may cause other types of cancer, such as skin cancer or cancer of the cervix. Ask your doctor about this risk.

If you use infliximab while you are pregnant, make sure any doctor caring for your new baby knows that you used the medicine during pregnancy. Being exposed to infliximab in the womb could affect your baby’s vaccination schedule during the first 6 months of life.

You should not breastfeed while you are receiving infliximab.

Remicade is not for use in children younger than 6 years old.

How is Remicade given?

Before you start treatment with Remicade, your doctor may perform tests to make sure you do not have tuberculosis or other infections.

Remicade is given as an infusion into a vein. A healthcare provider will give you this injection.

This medicine must be given slowly, and the infusion can take at least 2 hours to complete.

You may be watched closely after receiving infliximab, to make sure the medicine has not caused any serious side effects.

Infliximab affects your immune system. You may get infections more easily, even serious or fatal infections. Your doctor will need to examine you on a regular basis, and you may need frequent TB tests.

Serious infections may be more likely in older adults.

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

If you’ve ever had hepatitis B, using infliximab can cause this virus to become active or get worse. You may need frequent liver function tests while using this medicine and for several months after you stop.

What happens if I miss a dose?

Call your doctor for instructions if you miss an appointment for your Remicade injection.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line .

What should I avoid while receiving Remicade?

Avoid activities that may increase your risk of bleeding injury.

Do not receive a “live” vaccine while using infliximab, or you could develop a serious infection. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, and varicella (chickenpox).

Remicade side effects

Some side effects may occur during the injection. Tell your caregiver if you feel dizzy, nauseated, light-headed, itchy or tingly, short of breath, or have a headache, fever, chills, muscle or joint pain, pain or tightness in your throat, chest pain, or trouble swallowing during the injection. Infusion reactions may also occur within 1 or 2 hours after injection.

Get emergency medical help if you have signs of an allergic reaction to Remicade: hives; chest pain, difficult breathing; fever, chills, severe dizziness; swelling of your face, lips, tongue, or throat.

Renflexis https://drugonomy.com/2025/08/28/renflexis/ https://drugonomy.com/2025/08/28/renflexis/#respond Thu, 28 Aug 2025 15:49:30 +0000 https://medicine-21.com/Drugs/?p=2798 Generic name: infliximab-abda
Other brand names of infliximab-abda include: Renflixis
Dosage form: intravenous (infusion) injection
Drug class: TNF alfa inhibitors 

What is Renflexis?

Renflexis (infliximab-abda) is a monocloncal antibody used to treat a range of inflammatory autoimmune diseases.

Renflexis is a biological drug and one of four biosimilars of Remicade (infliximab). Biosimilar of Remicade are highly similar versions of the drug, which are designed to have the same effect, but which are not identical.

Renflexis works in the same way as the other versions of infliximab, by blocking the damage that results from too much tumor necrosis factor-alpha (TNF-alpha). Renflexis binds to TNF-alpha, which stops it from interacting with its receptors and activating certain processes.

TNF-alpha is a protein and inflammatory cytokine which plays a key role in your normal immune response. It is involved in your inflammatory response and also helps to fight off infection and cancer. Some people, however, produce too much TNF-alpha and this can cause an autoimmune disease to develop.

Renflexis was approved by the US Food and Drug Administration (FDA) in 2017, almost 20 years after the original version of infliximab started being used.

What is Renflexis used for?

Renflexis is a prescription medicine that is approved for patients with:

  • Rheumatoid Arthritis – adults with moderately to severely active rheumatoid arthritis, along with the medicine methotrexate.
  • Crohn’s Disease – children 6 years and older and adults with Crohn’s disease who have not responded well to other medicines.
  • Ankylosing Spondylitis
  • Psoriatic Arthritis
  • Plaque Psoriasis – adult patients with plaque psoriasis that is chronic (does not go away), severe, extensive, and/or disabling.
  • Ulcerative Colitis – children 6 years and older and adults with moderately to severely active ulcerative colitis who have not responded well to other medicines.

Important information

Renflexis may cause serious side effects, including:

1. Risk of infection

Renflexis is a medicine that affects your immune system. Renflexis can lower the ability of your immune system to fight infections. Serious infections have happened in patients receiving Renflexis. These infections include tuberculosis (TB) and infections caused by viruses, fungi or bacteria that have spread throughout the body. Some patients have died from these infections.

  • Your doctor should test you for TB before starting Renflexis.
  • Your doctor should monitor you closely for signs and symptoms of TB during treatment with Renflexis.

Before starting Renflexis, tell your doctor if you:

  • think you have an infection. You should not start receiving Renflexis if you have any kind of infection.
  • are being treated for an infection.
  • have signs of an infection, such as a fever, cough, flu-like symptoms.
  • have any open cuts or sores on your body.
  • get a lot of infections or have infections that keep coming back.
  • have diabetes or an immune system problem. People with these conditions have a higher chance for infections.
  • have TB, or have been in close contact with someone with TB.
  • live or have lived in certain parts of the country (such as the Ohio and Mississippi River valleys) where there is an increased risk for getting certain kinds of fungal infections (histoplasmosis, coccidioidomycosis, or blastomycosis). These infections may develop or become more severe if you receive Renflexis. If you do not know if you have lived in an area where histoplasmosis, coccidioidomycosis, or blastomycosis is common, ask your doctor.
  • have or have had hepatitis B.
  • use the medicines Kineret (anakinra), Orencia (abatacept), Actemra (tocilizumab), or other medicines called biologics used to treat the same conditions as Renflexis.

After starting Renflexis, if you have an infection, any sign of an infection including a fever, cough, flu-like symptoms, or have open cuts or sores on your body, call your doctor right away. Renflexis can make you more likely to get infections or make any infection that you have worse.

2. Risk of Cancer

  • There have been cases of unusual cancers in children and teenage patients using TNF-blocker medicines, such as Renflexis.
  • For children and adults receiving TNF-blocker medicines, including Renflexis, the chances of getting lymphoma or other cancers may increase.
  • Some people receiving TNF-blockers, including Renflexis, developed a rare type of cancer called hepatosplenic T-cell lymphoma. This type of cancer often results in death. Most of these people were male teenagers or young men. Also, most people were being treated for Crohn’s disease or ulcerative colitis with a TNF-blocker and another medicine called azathioprine or 6-mercaptopurine.
  • People who have been treated for rheumatoid arthritis, Crohn’s disease, ulcerative colitis, ankylosing spondylitis, psoriatic arthritis and plaque psoriasis for a long time may be more likely to develop lymphoma. This is especially true for people with very active disease.
  • Some people treated with infliximab products, such as Renflexis, have developed certain kinds of skin cancer. If any changes in the appearance of your skin or growths on your skin occur during or after your treatment with Renflexis, tell your doctor.
  • Patients with Chronic Obstructive Pulmonary Disease (COPD), a specific type of lung disease, may have an increased risk for getting cancer while being treated with Renflexis.
  • Some women being treated for rheumatoid arthritis with infliximab products have developed cervical cancer. For women receiving Renflexis, including those over 60 years of age, your doctor may recommend that you continue to be regularly screened for cervical cancer.
  • Tell your doctor if you have ever had any type of cancer. Discuss with your doctor any need to adjust medicines you may be taking.

See the section “What are the possible side effects of Renflexis?” below for more information.

Who should not receive Renflexis?

You should not receive Renflexis if you have:

  • heart failure, unless your doctor has examined you and decided that you are able to receive Renflexis. Talk to your doctor about your heart failure.
  • had an allergic reaction to infliximab products, or any of the other ingredients in Renflexis. See below for a complete list of ingredients in Renflexis.

What should I tell my doctor before receiving Renflexis?

Your doctor will assess your health before each treatment. Tell your doctor about all of your medical conditions, including if you:

  • have an infection (see “Important information” above).
  • have other liver problems including liver failure.
  • have heart failure or other heart conditions. If you have heart failure, it may get worse while you take Renflexis.
  • have or have had any type of cancer.
  • have had phototherapy (treatment with ultraviolet light or sunlight along with a medicine to make your skin sensitive to light) for psoriasis. You may have a higher chance of getting skin cancer while receiving Renflexis.
  • have COPD. Patients with COPD may have an increased risk of getting cancer while receiving Renflexis.
  • have or have had a condition that affects your nervous system such as:
    • multiple sclerosis, or Guillain-Barré syndrome, or
    • if you experience any numbness or tingling, or
    • if you have had a seizure.
  • have recently received or are scheduled to receive a vaccine. Adults and children receiving Renflexis should not receive live vaccines (for example, the Bacille Calmette-Guérin [BCG] vaccine) or treatment with a weakened bacteria (such as BCG for bladder cancer). Children should have all of their vaccines brought up to date before starting treatment with Renflexis.

How should I receive Renflexis?

  • You will be given Renflexis through a needle placed in a vein (IV or intravenous infusion) in your arm.
  • Your doctor may decide to give you medicine before starting the Renflexis infusion to prevent or lessen side effects.
  • Only a healthcare professional should prepare the medicine and administer it to you.
  • Renflexis will be given to you over a period of about 2 hours.
  • If you have side effects, the infusion may need to be adjusted or stopped. In addition, your healthcare professional may decide to treat your symptoms.
  • A healthcare professional will monitor you during the infusion and for a period of time afterward for side effects. Your doctor may do certain tests while you are receiving Renflexis to monitor you for side effects and to see how well you respond to the treatment.
  • Your doctor will determine the right dose for you and how often you should receive it. Make sure to discuss with your doctor when you will receive infusions and to come in for all your infusions and follow-up appointments.

What should I avoid while receiving Renflexis?

Repatha https://drugonomy.com/2025/08/28/repatha/ https://drugonomy.com/2025/08/28/repatha/#respond Thu, 28 Aug 2025 15:24:37 +0000 https://medicine-21.com/Drugs/?p=2792 Pronunciation: ri-PAth-a
Generic name: evolocumab
Dosage form: prefilled single-dose SureClick autoinjector (140 mg/mL), prefilled single-dose syringe (140 mg/mL), single-dose Pushtonex system (420 mg/3.5mL; on-body infusor with prefilled cartridge)
Drug class: PCSK9 inhibitors 

What is Repatha?

Repatha is used to lower high cholesterol alongside dietary changes and to reduce the risk of major cardiovascular events in those with cardiovascular disease, such as death from cardiovascular disease, heart attack, stroke, angina requiring hospitalization, or certain types of heart surgery.

It is given as an injection under the skin (subcutaneously), every 2 weeks or 1 time each month.

FDA-approved uses and indications

Repatha (evolocumab) is an injectable prescription medicine approved:

  • to reduce the risk of major adverse cardiovascular (CV) events, such as death from cardiovascular disease, heart attack, stroke, certain types of chest pain conditions (unstable angina) requiring hospitalization, or certain types of heart surgery, in adults with established cardiovascular disease
  • to reduce LDL-C in adults with primary hyperlipidemia, including heterozygous familial hypercholesterolemia (HeFH) as an adjunct to diet, alone, or in combination with other low-density lipoprotein cholesterol (LDL-C)-lowering therapies 
  • to reduce LDL-C in children aged 10 years and older with HeFH as an adjunct to diet and other LDL-C-lowering therapies 
  • to reduce LDL-C in adults and children aged 10 years and older with homozygous familial hypercholesterolemia (HoFH) as an adjunct to other LDL-C-lowering therapies.

It is not known if Repatha is safe and effective in children with HeFH or HoFH who are younger than 10 years of age or in children with other types of hyperlipidemia.

Repatha received FDA approval on August 27, 2015. There is no Repatha generic or biosimilar.

Mechanism of action

Repatha works by helping the liver reduce levels of “bad” cholesterol (low-density lipoprotein, or LDL) circulating in your blood.

Its mechanism involves binding to and blocking a protein called PCSK9 (Proprotein Convertase Subtilisin/Kexin Type 9) in the liver.

  • Normally, PCSK9 attaches to LDL receptors on liver cells and triggers their degradation.
  • These receptors are responsible for removing LDL (“bad”) cholesterol from the blood.
  • By inhibiting PCSK9, Repatha prevents the degradation of LDL receptors, allowing more of them to remain on liver cell surfaces and remove more LDL cholesterol from the blood.

Clinical trials report significant reductions in blood LDL cholesterol levels (often 50-60% or more).

How much does Repatha cost?

Repatha has broad coverage over most insurance types, so the cost of Repatha depends on the type of insurance you have. For example, with the Repatha Co-Pay card, those with commercial insurance pay as little as $15 a month. For those with Medicaid, 99% of Repatha prescriptions cost people $10 or less.

Side effects

The most common side effects of Repatha are:

  • Cold symptoms like a runny nose and sore throat
  • Flu or flu-like symptoms
  • Back pain
  • High blood sugar/diabetes

    • Do not try to inject Repatha until you or your child has been shown the right way by your healthcare provider or nurse.
  • You or your child can inject Repatha into the thigh, upper arm, or stomach (abdomen), except for a two-inch area around the belly button.
    • Your healthcare provider will show you the best places on your body to inject Repatha or place the on-body infusor. Use a different place each time you give an injection. Do not inject into the same place twice in a row.
    • Do not choose an area where the skin is tender, bruised, red, or hard. Avoid injecting into areas with scars or stretch.

If you or your child has HoFH, the recommended starting dose is 420 mg once a month. After 12 weeks, your healthcare provider may increase the dose to 420 mg every two weeks.

  • If you or your child receives lipid apheresis, your healthcare provider may decide to start you or your child on a dose of 420 mg every two weeks to match the apheresis treatment, and you or your child should take the dose after the apheresis treatment.

Repatha comes as a prefilled single-dose (1 time) autoinjector (SureClick autoinjector), as a prefilled single-dose syringe, or as a single-dose Pushtronex system (on-body infusor with prefilled cartridge). Your healthcare provider will prescribe the type and dose that is best for you or your child.

  • It may take up to 15 seconds to inject Repatha using a prefilled syringe or a SureClick autoinjector. If you use more than one injection at a time, be sure to finish all injections within 30 minutes.
  • Each single-use prefilled syringe, cartridge, or injection device is for one use only. Throw away after one use, even if there is still some medicine left inside. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof “sharps” container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
  • Full patient instructions with diagrams are available on the Repatha Package Insert.
  • Ask your doctor or pharmacist if you have any questions about your injection device, or call the manufacturer at 1-844-737-2842.

If your healthcare provider prescribes you or your child the 420 mg dose, you or your child may use:

  • a single-dose on-body infusor with the prefilled cartridge to give the injection over 5 minutes, or
  • 3 separate injections in a row, using a different prefilled single-dose SureClick autoinjector or prefilled single-dose syringe for each injection. Give all of these injections within 30 minutes.

If you or your child is using the prefilled single-dose SureClick autoinjector, put the yellow safety guard
(needle inside) of the prefilled single-dose SureClick autoinjector on the skin before injecting.

You should not stop using Repatha without your doctor’s advice, or your LDL cholesterol levels may increase.

Requip https://drugonomy.com/2025/08/28/requip/ https://drugonomy.com/2025/08/28/requip/#respond Thu, 28 Aug 2025 15:20:20 +0000 https://medicine-21.com/Drugs/?p=2789 Generic name: ropinirole (oral) [ roe-PIN-i-role ]
Other brand names of ropinirole (oral) include: Requip, Requip XL
Drug class: Dopaminergic antiparkinsonism agents 

What is Requip?

Requip is a dopaminergic agent and it has some of the same effects as dopamine, a naturally occuring chemical found in your body. Low levels of dopamine in the brain are associated with Parkinson’s disease.

Requip is used to treat symptoms of Parkinson’s disease (stiffness, tremors, muscle spasms, and poor muscle control). Ropinirole is also used to treat restless legs syndrome (RLS).

Only immediate-release Requip is approved to treat either Parkinson symptoms or RLS. Extended-release Requip XL is approved only to treat Parkinson symptoms.

Parkinson’s and RLS are two separate disorders. Having one of these conditions will not cause you to have the other condition.

Warnings

Requip may cause you to fall asleep during normal daytime activities such as working, talking, eating, or driving. You may fall asleep suddenly, even after feeling alert. Tell your doctor if you have any problems with daytime sleepiness or drowsiness. If you are unsure of how this medicine will affect you, be careful if you drive or do anything that requires you to be awake and alert.

You may have increased sexual urges, unusual urges to gamble, or other intense urges while taking this medication. Talk with your doctor if you believe you have any intense or unusual urges while taking Requip.

Do not share this medication with another person, even if they have the same symptoms you do. Avoid drinking alcohol, which can increase some of the side effects of Requip. Cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression or anxiety can add to sleepiness caused by ropinirole. Tell your doctor if you regularly use any of these other medicines.

Requip may cause hallucinations (the sensation of hearing or seeing something that is not there), most commonly among elderly people. Call your doctor if you experience hallucinations.

Do not stop using Requip or change your dose without first talking to your doctor. You may have side effects such as fever, muscle stiffness, and confusion if you stop the medication suddenly or if you change doses.

Some people taking medicines for Parkinson’s disease have developed skin cancer (melanoma). However, people with Parkinson’s disease may have a higher risk than most people for developing melanoma. Talk to your doctor about your specific risk and what skin symptoms to watch for. You may need to have regular skin examinations.

Before taking this medicine

You should not use Requip if you are allergic to ropinirole.

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

  • high or low blood pressure;
  • kidney disease (or if you are on dialysis);
  • heart disease, heart rhythm problems;
  • a sleep disorder such as narcolepsy, or other conditions that may cause daytime sleepiness; or
  • if you smoke.

People with Parkinson’s disease may have a higher risk of skin cancer (melanoma). Talk to your doctor about this risk and what skin symptoms to watch for.

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

It is not known whether ropinirole passes into breast milk or if it could affect the nursing baby. Ropinirole may slow breast milk production. Tell your doctor if you are breast-feeding.

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

How should I take Requip?

Take Requip exactly as it was prescribed for you. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.

If you are taking immediate-release Requip tablets you should not take the extended-release tablets at the same time.

The dose and timing of Requip in treating Parkinson’s disease is different from the dose and timing in treating RLS. Follow the directions on your prescription label. Ask your pharmacist if you have any questions about the kind of ropinirole you receive at the pharmacy.

Requip can be taken with or without food. Take the medicine at the same time each day.

Do not crush, chew, or break an extended-release Requip XL tablet. Swallow the tablet whole.

Call your doctor if you see part of the tablet in your stool. This is a sign that your body may not have absorbed all of the medicine.

If you are taking this medicine for RLS, tell your doctor if your symptoms get worse, if they occur in the morning or earlier than usual in the evening, or if you feel restless symptoms in your hands or arms.

It may take up to several weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve.

Do not stop using Requip suddenly, or you could have unpleasant withdrawal symptoms. Follow your doctor’s instructions about tapering your dose.

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

Retevmo https://drugonomy.com/2025/08/28/retevmo/ https://drugonomy.com/2025/08/28/retevmo/#respond Thu, 28 Aug 2025 15:05:26 +0000 https://medicine-21.com/Drugs/?p=2780 Pronunciation: reh-TEHV-moh
Generic name: selpercatinib
Dosage form: oral capsule, oral tablet
Drug class: Multikinase inhibitors 

What is Retevmo?

Retevmo (selpercatinib) is an oral kinase inhibitor that may be used to treat the following cancers caused by abnormal RET (rearranged during transfection) genes:

  • locally advanced non-small cell lung cancer (NSCLC) or NSCLC that has spread in adults
  • advanced or metastatic thyroid cancer in adults and children aged 2 years of age and older who require systemic therapy and who are radioactive iodine-refractory (if radioactive iodine is appropriate)
  • advanced medullary thyroid cancer (MTC) or MTC that has spread and requires a medicine that treats the whole body (systemic therapy) in adults and children aged 2 years and older.

Retevmo is also approved under the accelerated approval designation for adults and children aged 2 years and older with locally advanced solid tumors (cancers) or solid tumors associated with abnormal RET genes that have spread or gotten worse (progressed) after other treatments, or who have no satisfactory alternative treatment options.

Note: Continued approval under the accelerated approval designation is contingent upon a continued benefit in clinical trials.

Your healthcare provider will perform a test for abnormal RET genes to make sure that Retevmo is right for you.

It is not known if Retevmo is safe and effective when used in children younger than 2 years of age for the treatment of MTC, thyroid cancer, solid tumors, or other cancers.

Retevmo first gained FDA-approval on May 8, 2020.

Retevmo side effects

The most common side effects of Retevmo include:

  • swelling of your arms, legs, hands, and feet (edema)
  • diarrhea
  • tiredness
  • dry mouth
  • high blood pressure
  • stomach-area (abdominal) pain
  • constipation
  • rash
  • nausea
  • headache.

The most common severe abnormal laboratory test results with Retevmo include decreased white blood cell count, decreased levels of sodium in the blood, and decreased levels of calcium in the blood.

Retevmo may affect fertility in females and males, which may affect your ability to have children. Talk to your healthcare provider if this is a concern for you.

Serious side effects

Retevmo may cause serious side effects, including:

  • Liver problems. Liver problems (increased liver enzymes) are common with Retevmo and may sometimes be serious.

    • shortness of breath
    • cough
    • fever
  • High blood pressure (hypertension). High blood pressure is common with Retevmo and may sometimes be serious. You should check your blood pressure regularly during treatment. Tell your healthcare provider if you get any of the following symptoms:
    • confusion
    • headaches
    • shortness of breath
    • dizziness
    • chest pain
  • Heart rhythm changes (QT prolongation) can occur and may be serious. Retevmo may cause very slow, very fast or irregular heartbeats. Tell your healthcare provider right away if you get any of the following symptoms:
    • loss of consciousness

Rexulti https://drugonomy.com/2025/08/28/rexulti/ https://drugonomy.com/2025/08/28/rexulti/#respond Thu, 28 Aug 2025 14:57:24 +0000 https://medicine-21.com/Drugs/?p=2774 Pronunciation: REX-ul-TE
Generic name: brexpiprazole
Dosage form: oral tablet (0.25 mg, 0.5 mg, 1 mg, 2 mg, 3 mg, 4 mg)
Drug class: Atypical antipsychotics 

What is Rexulti?

Rexulti is an antipsychotic used to treat major depressive disorder, schizophrenia, or agitation associated with dementia due to Alzheimer’s disease. It is an oral tablet that is taken once a day.

Rexulti’s mechanism of action involves adjusting the imbalance of natural chemicals in the brain (also called neurotransmitters), such as dopamine and serotonin. These neurotransmitters help cells to send messages to each other. An imbalance of these natural chemicals is thought to be associated with several psychiatric conditions, including schizophrenia, depression, and agitation associated with dementia due to Alzheimer’s disease .

Rexulti (brexpiprazole) first gained FDA approval on July 10, 2015. Rexulti belongs to the drug class called atypical antipsychotics.

Rexulti is available as a generic under the name brexpiprazole. The brexpiprazole generic is only approved for depression and schizophrenia in adults, whereas the brand Rexulti is also approved for adolescents aged 13 and older with schizophrenia and for dementia-related agitation in Alzheimer’s disease.

Rexulti uses

Rexulti is an atypical antipsychotic used:

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

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

It is not known if Rexulti is safe and effective for the treatment of MDD in children or the treatment of schizophrenia in children under 13 years of age.

Rexulti side effects

The most common side effects of Rexulti are:

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

Serious side effects and warnings

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

Increased risk of suicidal thoughts and actions. Rexulti 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 Rexulti 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 aggressively, being angry, or being 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 Rexulti 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), 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). Rexulti 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 Rexulti. Tardive dyskinesia may also start after you stop taking Rexulti.

Rexulti 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 Rexulti. 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 Rexulti and then regularly during long-term treatment with Rexulti. Call your healthcare provider if you have any of these symptoms of high blood sugar during treatment with Rexulti:
    • 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 Rexulti, and then periodically during treatment with Rexulti.
  • Weight gain. You and your healthcare provider should check your weight before you start and often during treatment with Rexulti.

Unusual and uncontrollable (compulsive) urges. Some people taking Rexulti 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 unusually 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 Rexulti.

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. Rexulti 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). Rexulti may increase your risk of seizures.

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

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 Rexulti?”

Rexulti may harm an unborn baby.

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

What is Reyvow?

Reyvow is a serotonin (5-HT) 1F receptor agonist.

Reyvow is used in adults to treat migraine headaches with or without aura.

Reyvow will only treat and will not prevent migraine headache.

Warnings

Reyvow is a federally controlled substance (CV) because it contains lasmiditan that can be a target for people who abuse prescription medicines or street drugs.

Keep this medicine in a safe place to protect it from theft. Never give your Reyvow to anyone else, because it may harm them. Selling or giving away Reyvow is against the law. Tell your healthcare provider if you have ever abused or been dependent on alcohol, prescription medicines or street drugs.

Before taking this medicine

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

  • an allergy to lasmiditan;

  • high blood pressure; or
  • drug addiction.

Be sure your doctor knows if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson’s disease, migraine headaches, serious infections, or prevention of nausea and vomiting. These medicines may interact with lasmiditan and cause a serious condition called serotonin syndrome.

If you are pregnant, your name may be listed on a pregnancy registry to track the effects of lasmiditan on the baby.

Tell your doctor if you are pregnant or plan to become pregnant. It is not known whether lasmiditan will harm an unborn baby. However, having migraine headaches during pregnancy may cause complications such as eclampsia (dangerously high blood pressure that can lead to medical problems in both mother and baby). The benefit of treating migraines may outweigh any risks to the baby.

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

How should I take Reyvow?

Take Reyvow exactly as prescribed by your doctor. Follow the directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Take Reyvow soon as you notice headache symptoms.

Swallow the tablet whole and do not crush, chew, or break it.

Do not take more than one dose in a 24-hour period.

You may take this medicine with or without food.

Never use more than your recommended dose. Overuse of migraine headache medicine can make headaches worse. Tell your doctor if the medicine seems to stop working as well in treating your migraine attacks.

Call your doctor if your headache does not go away completely, or if you have more than 4 headaches in one month (30 days).

Store at room temperature away from moisture and heat.

Keep track of your medicine. You should be aware if anyone is using it improperly or without a prescription.

A healthcare provider will give you rifampin injection. Tell your caregivers if you feel any burning, pain, or swelling around the IV needle when rifampin is injected.

Rifampin may cause temporary discoloration of your teeth, sweat, urine, saliva, and tears (a yellow, orange, red, or brown color). This side effect is usually not harmful. However, soft contact lenses may be permanently stained if you wear them while using rifampin.

Dark colored urine can be a sign of liver problems. Call your doctor if you have reddish-brown urine together with upper stomach pain, loss of appetite, and jaundice (yellowing of your skin or eyes).

Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may increase your risk of further infection that is resistant to antibiotics. Rifampin will not treat a viral infection such as the flu or a common cold.

You should not stop using rifampin without your doctor’s advice. Stopping the medicine suddenly and later starting again may cause kidney problems. Rifampin is usually given until lab tests show that the infection has cleared.

While using rifampin, you may need frequent blood tests.

This medicine may affect a drug-screening urine test and you may have false results. Tell the laboratory staff that you use rifampin.

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

Rimegepant https://drugonomy.com/2025/08/28/rimegepant/ https://drugonomy.com/2025/08/28/rimegepant/#respond Thu, 28 Aug 2025 14:38:41 +0000 https://medicine-21.com/Drugs/?p=2760 Generic name: rimegepant [ ri-ME-je-pant ]
Brand name: Nurtec ODT
Drug class: CGRP inhibitors 

What is rimegepant?

Rimegepant is a prescription medicine used by adults to treat migraines (with or without aura) when they occur and also to prevent episodic migraines. Rimegepant works to reduce migraine symptoms of headache, nausea, vomiting, light sensitivity and sound sensitivity, by blocking CGRP receptors. This medicine may reduce the number of monthly migraine days when taken to prevent episodic migraines.

Rimegepant is an orally disintegrating tablet (ODT) that dissolves in the mouth without the need to take it with a glass of water. Because the tablet dissolves in the mouth it is absorbed into the bloodstream quickly, with the highest blood concentrations reached after one and a half hours.

Warnings

It is not known if it is safe to take rimegepant ODT for more than 15 migraine headaches in 30 days.

Rimegepant ODT can be taken 1 time each day as needed. You should not take more than 1 tablet in 24 hours.

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.

If you take too much rimegepant ODT, go to the nearest emergency room right away.

Before taking this medicine

You should not use rimegepant if you are allergic to it.

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

  • liver disease; or
  • kidney disease (or if you are on dialysis).

It is not known whether rimegepant will harm an unborn baby. However, having migraine headaches may cause complications during pregnancy such as dangerously high blood pressure that can lead to medical problems in both mother and baby. The benefit of treating migraines may outweigh any risks to the baby.

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

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

How should I take rimegepant?

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

Call your doctor if your symptoms do not improve, or if you have more than 15 headaches in one month (30 days).

Remove an orally disintegrating tablet from the package only when you are ready to take the medicine.

  • Use dry hands when opening the blister pack.
  • Peel back the foil covering of one blister and gently remove the orally disintegrating tablet (ODT). Do not push the ODT through the foil.
  • As soon as the blister is opened, remove the ODT and place on the tongue; alternatively, the ODT may be placed under the tongue.
  • The ODT will disintegrate in saliva so that it can be swallowed without additional liquid.
  • Swallow several times as the tablet dissolves.
  • Take the ODT immediately after opening the blister pack. Do not store the ODT outside the blister pack for future use.

Store at cool room temperature, away from moisture and heat.

Dosing information

Usual Adult Dose for Migraine:

75 mg orally
Maximum dose: 75 mg in a 24-hour period

Comments:
-This drug is not for the preventive treatment of migraine.

Place on tongue (or under tongue) and allow to disintegrate in saliva and swallow; additional liquid is not necessary. Do not take more than 1 dose in 24-hours.

What happens if I miss a dose?

Seek emergency medical attention or call the Poison Help line .

What to avoid

Follow your doctor’s instructions about any restrictions on food, beverages, or activity.

What is Rinvoq?

Rinvoq (upadacitinib) is an oral Janus kinase (JAK) inhibitor that may be used alone or in combination with other medications to treat several conditions that have inflammation as a characteristic symptom. It works by decreasing the activity of the immune system. Rinvoq is used to treat:

  • Rheumatoid arthritis in people who are unable to take or have not responded well to one or more tumor necrosis factor (TNF) inhibitor medication(s)
  • Psoriatic arthritis (a condition that causes joint pain and swelling, and scales on the skin) in adults who are unable to take or did not respond to or tolerate one or more TNF inhibitor medication(s)
  • Symptoms of eczema (atopic dermatitis; a skin disease that causes the skin to be dry and itchy and to sometimes develop red, scaly rashes) in adults and children 12 years and older who cannot use other medications for their condition, or whose eczema has not responded to other medications
  • Ulcerative colitis (a condition that causes swelling and sores in the lining of the colon [large intestine] and rectum) in adults who are unable to take or who did not respond to one or more TNF inhibitor medication(s)
  • Crohn’s disease (a condition in which the body attacks the lining of the digestive tract, causing pain, diarrhea, weight loss, and fever) in adults who cannot take or who did not respond to one or more TNF inhibitor medication(s)
  • Ankylosing spondylitis (a condition in which the body attacks the joints of the spine and other areas, causing pain, swelling, and joint damage) in adults who are unable to take or who did not respond to one or more TNF inhibitor medication(s)
  • Giant cell arteritis (an inflammatory condition of the temporal arteries) in adults
  • Active non-radiographic axial spondyloarthritis (a condition in which the body attacks the joints of the spine and other areas, causing pain and signs of swelling), but without changes seen on X-ray, in adults who are unable to take or who did not respond to one or more TNF inhibitor medication(s)
  • Active polyarticular juvenile idiopathic arthritis in children 2 years and older who have had an inadequate response or intolerance to one or more TNF blockers.

There are two formulations of Rinvoq: Rinvoq extended-release tablets and Rinvoq LQ liquid solution. These two formulations are not interchangeable. Rinvoq is not a substitute for Rinvoq LQ.

  • Rinvoq is not recommended in combination with other JAK inhibitors, biologic DMARDs, or potent immunosuppressants such as azathioprine and cyclosporine.

Rinvoq was FDA approved on August 16, 2019, and Rinvoq LQ was approved on April 26, 2024

How should I take risedronate?

Risedronate tablets come in different strengths (number of milligrams per pill) that are taken on different schedules. You may need to take a tablet once per day, once per week, once per month, or for 2 days in a row once per month.

Your dosing schedule will depend on why you are taking risedronate and in what tablet strength. If you change strengths, you may also need to change your schedule.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed. Risedronate is often given for only 3 to 5 years.

Take the Actonel tablet first thing in the morning with a full glass (6 to 8 ounces) of water, at least 30 minutes before you eat or drink anything or take any other medicine.

Take the Atelvia tablet just after breakfast, with at least 4 ounces of water.

Use only plain water when taking a risedronate tablet. Do not use coffee, tea, soda, juice, or mineral water.

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

For at least 30 minutes after taking risedronate:

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

Take this medicine at the same time each day or on the same day each week or each month (depending on your dosing schedule).

Pay special attention to your dental hygiene while taking risedronate. Brush and floss your teeth regularly. If you need to have any dental work (especially surgery), tell the dentist ahead of time that you are using risedronate.

Risedronate 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. Keep unused effervescent tablets in the foil blister pack.

What happens if I miss a dose?

Once-daily dosing: If you forget to take risedronate first thing in the morning, do not take it later in the day. Wait until the following morning and skip the missed dose. Do not take two (2) doses in one day.

Once-per-week or once-per-month dosing: If you forget to take risedronate on your scheduled day, take it first thing in the morning on the day after you remember the missed dose. Then return to your regular weekly or monthly schedule on your chosen dose day. Do not take 2 doses in one day.

Call your doctor for instructions if you miss more than 2 doses in a month.

What happens if I overdose?

Drink a full glass of milk and seek emergency medical attention or call the Poison Help line

What should I avoid while taking risedronate?

Do not take two different brands or strengths of risedronate at the same time.

Avoid taking any other medicines for at least 30 minutes after taking risedronate. This includes vitamins, calcium, iron, antacids, or laxatives. Some medicines can make it harder for your body to absorb risedronate.

Avoid smoking, or try to quit. Smoking can reduce your bone mineral density, making fractures more likely.

Avoid drinking large amounts of alcohol. Heavy drinking can also cause bone loss.
