Brand names: Prozac, Sarafem,  Rapiflux,  Selfemra
Drug class: Selective serotonin reuptake inhibitors 

What is fluoxetine?

Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) antidepressant. Fluoxetine inhibits the uptake of serotonin by a nerve cells (neurons) and helps people with depression, panic, anxiety, or obsessive-compulsive symptoms.

Fluoxetine is a  prescription medicine used to treat major depressive disorder, bulimia nervosa (an eating disorder), obsessive-compulsive disorder, panic disorder, and premenstrual dysphoric disorder (PMDD).

Fluoxetine is sometimes used together with another medication called olanzapine (Zyprexa) to treat manic depression caused by bipolar disorder. This combination is also used to treat depression after at least 2 other medications have been tried without successful treatment of symptoms.

If you also take olanzapine (Zyprexa), read the Zyprexa medication guide and all patient warnings and instructions provided with that medication.

Warnings

You should not use fluoxetine if you also take pimozide or thioridazine, or if you are being treated with methylene blue injection.

Do not use fluoxetine if you have used an MAO inhibitor in the past 14 days (such as isocarboxazid, rasagiline, selegiline, phenelzine, or transcypromine). Do not use fluoxetine with thioridazine, linezolid, pimozide, or methylene blue injection.

You must wait at least 14 days after stopping an MAO inhibitor before you take fluoxetine. You must wait 5 weeks after stopping fluoxetine before you can take thioridazine or an MAOI.

Some young people have thoughts about suicide when first taking an antidepressant. Stay alert to changes in your mood or symptoms.

Fluoxetine could impair judgment, thinking, or motor skills. Use caution when operating machinery.

Report any new or worsening symptoms to your doctor, such as: mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself.

Do not stop using fluoxetine without first asking your doctor.

Before taking this medicine

You should not use this medicine if you are allergic to fluoxetine, if you also take pimozide or thioridazine.

Do not use fluoxetine if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, and tranylcypromine. You must wait at least 14 days after stopping an MAO inhibitor before you take fluoxetine. You must wait 5 weeks after stopping fluoxetine before you can take thioridazine or an MAOI.

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

  • cirrhosis of the liver;
  • urination problems;
  • diabetes;
  • narrow-angle glaucoma;
  • seizures or epilepsy;
  • sexual problems;
  • bipolar disorder (manic depression);
  • drug abuse or suicidal thoughts; or
  • electroconvulsive therapy (ECT).

Some young people have thoughts about suicide when first taking an antidepressant. Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.

Older adults may be more sensitive to the effects of fluoxetine.

Ask your doctor about taking fluoxetine if you are pregnant. Taking an SSRI antidepressant during late pregnancy may cause serious medical complications in the baby. However, you may have a relapse of depression if you stop taking your antidepressant. Tell your doctor right away if you become pregnant. If you are pregnant, your name may be listed on a pregnancy registry to track the effects of fluoxetine on the baby.

If you are breastfeeding, tell your doctor if you notice agitation, fussiness, feeding problems, or poor weight gain in the nursing baby.

How should I take fluoxetine?

Take fluoxetine 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.

Swallow the delayed-release capsule whole and do not crush, chew, break, or open it.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

It may take up to 4 weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve.

Tell your doctor if you have any changes in sexual function, such as loss of interest in sex, trouble having an orgasm, or (in men) problems with erections or ejaculation. Some sexual problems can be treated.

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

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

Rinse your mouth with water without swallowing after each use of your inhaler.

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

If you also use an oral steroid medication, you should not stop using it suddenly. Follow your doctor’s instructions about tapering your dose.

If you use a peak flow meter at home, tell your doctor if your numbers are lower than normal.

Your vision and your bone mineral density may need to be checked often.

Store your medicine at room temperature, away from moisture, heat, and sunlight. Avoid high heat, such as open flame or in a car on a hot day. Carefully follow all storage and disposal directions provided with your medicine.

Once your asthma is under control, your doctor may want you to stop using this medicine. Do not stop using the medicine unless your doctor tells you to.

What happens if I miss a dose?

Skip the missed dose and use your next dose at the regular time. Do not use two doses at one time.

Seek emergency medical attention or call the Poison Help line .

Overdose symptoms may include chest pain, fast heart rate, and feeling shaky or short of breath.

Long term use of an inhaled steroid can lead to glaucoma, cataracts, thinning skin, changes in body fat (especially in your face, neck, back, and waist), increased acne or facial hair, menstrual problems, impotence, or loss of interest in sex.

What should I avoid while using fluticasone and salmeterol?

Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chickenpox or measles. These conditions can be serious or even fatal in people who are using a steroid such as fluticasone.

Do not use a second inhaled bronchodilator unless your doctor tells you to. This includes formoterol (Perforomist, Symbicort, Bevespi, Dulera), arformoterol (Brovana), indacaterol (Arcapta), olodaterol (Striverdi,  Stiolto Respimat), salmeterol (Serevent), or vilanterol (Anoro Ellipta, Breo Ellipta, Trelegy Ellipta).

What other drugs will affect fluticasone and salmeterol?

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

Tell your doctor about all your other medicines, especially:

  • antifungal medicine; or
  • medicine to treat HIV or AIDS.

Folic acid https://drugonomy.com/2025/12/05/folic-acid/ https://drugonomy.com/2025/12/05/folic-acid/#respond Fri, 05 Dec 2025 21:04:36 +0000 https://medicine-21.com/Drugs/?p=8389 Pronunciation: foe-lick as-id
Generic name: folic acid
Brand names: FA-8, Folacin-800, FaLessa, Folvite
Dosage form: oral tablet (0.4 mg; 0.8 mg; 1 mg), injection
Drug class: Vitamins 

What is folic acid?

Folic acid (vitamin B9) is a B vitamin supplement that may be used to prevent and treat folate deficiency (low blood levels of folate) that can cause megaloblastic anemia. Folic acid may also be used to control high levels of homocysteine, prevent serious birth defects in pregnant women or women who think they may be pregnant, and prevent methotrexate-induced folate deficiency in people prescribed methotrexate.

Folic acid has been FDA approved since 1947.

Folate vs folic acid

Folate is the natural form of vitamin B9 found in various foods. Folic acid is the man-made form of vitamin B9 created in a laboratory that is added to fortified foods or used as a supplement. Folic acid is more stable and easier to absorb than naturally occurring folate in food. When you take folic acid, your body turns it into folate.

Folic acid benefits

Vitamin B9 (folate, folic acid) plays a crucial role in healthy red blood cell production and is also vital for cell growth, repair, and DNA synthesis.

  • Red blood cells carry oxygen throughout your body, and folate deficiency can lead to a type of anemia called folate-deficiency anemia. Symptoms of this anemia include fatigue, weakness, shortness of breath, and pale skin.
  • Folate is especially important during periods of rapid cell division, such as pregnancy and fetal development.

Benefits of folic acid supplementation include:

Preventing and treating folate-deficiency anemia. Folate is vital for the production of red blood cells (RBCs) and low levels of folate can cause folate-deficiency anemia (known medically as megaloblastic anemia), characterized by RBCs that are unusually large, structurally abnormal, and do not function properly. There are also fewer of them.

Preventing neural tube and other birth defects in the developing fetus in pregnant women. Folic acid helps ensure the proper closure of the neural tube early in pregnancy. The neural tube forms the brain, spinal cord, and surrounding structures and closes 28 to 32 days after a baby is conceived, which is often before many women know they are pregnant. This is why the CDC recommends all people capable of becoming pregnant get 400 micrograms (mcg) of folic acid daily.

  • This means women should start taking folic acid BEFORE they are pregnant, at the time they decide to try for a baby.

Lowering high levels of homocysteine in the blood (hyperhomocysteinemia). This can be caused by low dietary intake of folic acid, folate, vitamin B6, vitamin B12, thyroid disease, kidney disease, psoriasis, genetic reasons, or some medications. High homocysteine levels can damage the lining of the arteries and make blood clot more easily which can increase your risk of cardiovascular disease.

Reducing toxicity caused by the drug methotrexate. Methotrexate can cause low levels of folate in the body which can increase the risk of side effects such as nausea, vomiting, and mouth sores. Taking folic acid 5mg weekly, on a different day to the methotrexate dose seems to reduce these side effects.

Potential Other Benefits. Research is ongoing, but folic acid may have other benefits, such as reducing the risk of certain cancers, supporting mood and cognitive function, and possibly reducing the risk of dementia and the development of autism spectrum disorder (ASD).

What are the symptoms of folate deficiency?

Folate deficiency can be caused by not enough folate in the diet, a problem absorbing folate, or an increased need for folate (for example pregnant or breastfeeding women). Folate deficiency symptoms include:

  • fatigue, feeling tired, or rundown
  • heart palpitations or a fast heartbeat
  • shortness of breath
  • mouth ulcers, or an inflamed and painful tongue
  • mood changes, such as depression or irritability
  • sleep problems, such as insomnia,
  • cognitive problems, such as a decline in thinking and memory.

Pregnant women who are folate deficient or do not consume enough daily dietary folate or folic acid during the first few weeks of pregnancy have an increased risk of their baby having a birth defect, such as spina bifida (incomplete closure of the spinal cord), anencephaly (misinformation of the brain or skull), congenital heart disease (malformation of the heart), cleft lip and palate (abnormal closure of the lip and palate), problems with the development of the arms and legs, or an abnormal formation of the kidneys or bladder (obstructive uropathies).

Folic acid foods

Folic acid is added to some staple foods to ensure broader access to this crucial vitamin and prevent birth defects.

  • Since 1998, the United States has mandated the fortification of cereal grains with folic acid. Fortified foods high in folic acid are labeled “enriched” and include flour (including corn masa flour used to make corn tortillas) pasta, bread, rice, and breakfast cereal.
  • Some other foods also have folic acid added under voluntary fortification rules, but these manufacturers need to follow the FDA food additive regulations.

Certain natural food sources remain excellent sources of folate. Folate-rich foods include:

  • Leafy green vegetables such as spinach, kale, collard and mustard greens, and turnip greens.
  • Other vegetables including okra, asparagus, and brussels sprouts are good choices.
  • Fruits while not as high as vegetables, certain fruits like oranges, papayas, and strawberries contribute folate.
  • Beans and legumes such as lentils, black beans, peanuts, black-eyed peas, kidney beans, and chickpeas
  • Other folate-containing foods include yeast, mushrooms, animal liver and kidney, orange juice, and tomato juice.

Folic acid supplement side effects

Folic acid side effects are more likely to occur with higher dosages of folic acid (up to 15 mg/day) and include:

  • nausea
  • loss of appetite
  • bloating or gas
  • stomach pain
  • bitter or unpleasant taste in your mouth
  • confusion or trouble concentrating
  • sleep problems
  • mood changes, such as depression or excitement
  • impaired judgment.

Low vitamin B12 levels may occur in patients receiving prolonged folic acid therapy.

Serious side effects and warnings

Folic acid is relatively nontoxic in humans but rare instances of an allergic reaction to folic acid have been reported. You should not use this medication if you have ever had an allergic reaction to folic acid. Get emergency medical help if you have signs of an allergic reaction to folic acid: hives, rash, itching, skin redness, wheezing, difficulty breathing, swelling of your face, lips, tongue, or throat.

May increase the risk of seizures in some people with epilepsy receiving phenobarbital, primidone, or diphenylhydantoin.

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

Before taking this medicine

You should not use this medicine if you have ever had an allergic reaction to folic acid.

Ask a doctor or pharmacist if this medicine is safe to use if you have ever had:

  • epilepsy or other seizure disorder
  • cirrhosis or other liver disease
  • kidney disease (or if you are on dialysis)
  • hemolytic anemia
  • pernicious anemia
  • anemia that has not been diagnosed by a doctor and confirmed with laboratory testing
  • a condition that affects how well you absorb nutrients, such as celiac disease or inflammatory bowel disease
  • an infection or
  • alcoholism.

Tell your doctor if you are pregnant or breastfeeding.

These conditions may be causing folate deficiency, require additional medications or a higher dose of folic acid, or further laboratory investigation. For example:

  • Folic acid in dosages above 0.4mg daily may hide laboratory changes caused by pernicious anemia without halting the progression of neurological changes. This may result in severe nervous system damage before the correct diagnosis is made.

Pregnancy

Folic acid requirements markedly increase during pregnancy and deficiency will cause harm to the unborn baby. Studies in pregnant women have not shown that folic acid increases the risk of fetal abnormalities if
administered during pregnancy.

Breastfeeding

Folic acid is excreted in the milk of breastfeeding mothers. During lactation, folic acid requirements are
markedly increased; however, amounts present in human milk are adequate to fulfill infant requirements,
although supplementation may be needed in low-birth-weight infants, in those who are breast-fed by
mothers with folic acid deficiency (50 mcg daily), or in those with infections or prolonged diarrhea.

Fertility

Long-term studies to evaluate the effect of folic acid on fertility have not been conducted.

How should I use folic acid supplements?

Take folic acid exactly as prescribed by your doctor. Do not take it in larger amounts or for longer than recommended. Follow all directions on your medicine label and package.

Oral administration of folic acid is preferred.

  • Although most patients with malabsorption cannot absorb food folates, they can absorb folic acid given orally.
  • Administration by injection is not usually recommended but may be necessary for some people receiving parenteral or enteral nutrition.

Folic acid tablets are usually taken by mouth with a full glass of water.

Folic acid injection is given into a muscle, under the skin, or into a vein. A healthcare provider will give you this injection.

Your doctor may occasionally change your dose depending on your blood tests to make sure you get the best results from this medication.

Folic acid is sometimes used in combination with other medications to treat pernicious anemia.

Folic Acid Dosing

Folic acid is an important nutrient and folate or folic acid should be consumed daily.

  • The recommended dietary allowance (RDA) of folic acid for adults is 400 mcg DFE (dietary folate equivalents) daily.
    • 1 mcg DFE is the same as 1 mcg of folate in food or 0.6 mcg of folic acid supplements. This is because you absorb more from folic acid supplements than you do from food.
  • In pregnancy, the RDA of folic acid is 600 mcg DFE daily (some sources recommend 400 to 800 mcg DFE)
  • In breastfeeding, the RDA of folic acid is 500 mcg DFE daily.
  • In children, the RDA depends on age.
    • Birth to 6 months: 65 mcg DFE
    • Infants 7–12 months: 80 mcg DFE
    • Children 1–3 years: 150 mcg DFE
    • Children 4–8 years: 200 mcg DFE
    • Children 9–13 years: 300 mcg DFE
    • Teens 14–18 years: 400 mcg DFE
    • Adults 19+ years: 400 mcg DFE.

Megaloblastic Anemia

  • Adults: 1 mg folic acid once a day.
    • Rule out B12 deficiency.
    • Dosages of up to 5 mg may be used if indicated.
    • May continue until clinical symptoms of folate deficiency and the hematological profile have normalized.

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?

Except during pregnancy and lactation, folic acid should not be given in dosages higher than 0.4 mg daily until pernicious anemia has been ruled out.

Call your healthcare provider, seek emergency medical attention, or call the Poison Help line if you take more folic acid than recommended.

What should I avoid while taking folic acid?

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

What other drugs will affect folic acid?

Ask a doctor or pharmacist before using folic acid with any other medications, especially:

  • methotrexate
  • nitrofurantoin
  • pyrimethamine
  • tetracycline. False low serum and red cell folate levels may occur with some antibiotics that suppress the growth of Lactobacillus casei.
  • a barbiturate such as phenobarbital or secobarbital
  • seizure medicine such as phenytoin or primidone. The anticonvulsant action of some seizure medications can be antagonized by folic acid and increased dosages of the anticonvulsant may be needed
  • sulfasalazine. May reduce the body’s ability to absorb folate.

Formoterol (Inhalation) https://drugonomy.com/2025/12/05/formoterol-inhalation-2/ https://drugonomy.com/2025/12/05/formoterol-inhalation-2/#respond Fri, 05 Dec 2025 21:02:32 +0000 https://medicine-21.com/Drugs/?p=8386 Generic name: formoterol [ for-MOE-ter-ol ]
Brand names: Foradil Aerolizer, Perforomist
Drug class: Adrenergic bronchdilators

Uses for formoterol

Formoterol is used together with other medicines (eg, inhaled corticosteroids) to treat asthma and prevent bronchospasm in patients with asthma. When used regularly every day, inhaled formoterol decreases the number and severity of asthma attacks. However, it will not relieve an asthma attack that has already started.

Formoterol is also used for the long-term maintenance treatment of air flow blockage in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. COPD is a long-term lung disease that causes bronchospasm (wheezing or difficulty with breathing).

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

Formoterol is also used to prevent troubled breathing or wheezing caused by exercise (exercise-induced bronchospasm or EIB).

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

Before using formoterol

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

Allergies

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

Pediatric

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of formoterol inhalation powder in children 5 years of age and older. Safety and efficacy have not been established for children younger than 5 years of age.

Formoterol inhalation solutionis not indicated for use in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of formoterol in the elderly. However, elderly patients are more likely to have age-related heart or blood vessel disease, which may require caution in patients receiving formoterol.

Breast Feeding

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

Proper use of formoterol

Use this medicine only as directed by your doctor. Do not use more of it and do not use it more often than recommended on the label, unless otherwise directed by your doctor. Using the medicine more often may increase the chance of serious unwanted effects.

Inhaled formoterol is used to prevent asthma or COPD attacks. It is not used to relieve an attack that has already started. For relief of an asthma or COPD attack that has already started, you should use another medicine. If you do not have another medicine to use, or if you have any questions about this, check with your doctor.

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

Do not stop using this medicine or other asthma or COPD medicines that your doctor has prescribed for you unless you have discussed this with your doctor.

The formoterol inhalation solution should be used with a jet nebulizer that is connected to an air compressor with good air flow. The inhalation solution comes with a patient information leaflet and patient instructions. Read and follow the directions carefully before using this medicine. If you do not understand the directions or you are not sure how to use the nebulizer, ask your doctor to show you what to do. Also, ask your doctor to check how you use the inhaler to make sure you are using it properly.

To use the inhalation solution in the nebulizer:

Precautions while using formoterol

It is very important that your doctor check your progress at regular visits to make sure the medicine is working properly. Blood tests may be needed to check for any unwanted effects.

If your symptoms do not improve within a few days or if they become worse, check with your doctor.

Tell your doctor if you are also using other medicines for your COPD. Your doctor may want you to stop using the medicine and use it only during a severe COPD attack. Follow your doctor’s instructions on how you should take your medicine.

This medicine should not be used if you are having a severe COPD attack, or if symptoms of a COPD attack has already started. Your doctor may prescribe another medicine for you to use in case of an acute COPD attack. If the other medicine does not work as well, tell your doctor right away.

This medicine should not be used together with similar inhaled medicines such as arformoterol (Brovana™), budesonide/formoterol (Symbicort®), indacaterol (Arcapta® Neohaler®), salmeterol (Serevent®), or salmeterol/fluticasone (Advair®).

This medicine should only be used as an additional treatment for patients who cannot be treated with other asthma medicines (such as inhaled corticosteroids) or for asthma patients that require two medicines, including formoterol. Ask your doctor if you have any questions.

Talk to your doctor or get medical care right away if:

  • Your or your child’s symptoms do not improve after using this medicine for 1 week or if they become worse.
  • Your short-acting inhaler does not seem to be working as well as usual and you need to use it more often (eg, you use 1 whole canister of your short-acting inhaler in 8 weeks time, or you need to use 4 or more inhalations of your short-acting inhaler for 2 or more days in a row).
  • You have a significant decrease in your peak flow when measured as directed by your doctor.

You or your child may also be using an anti-inflammatory medicine, such as a steroid, together with this medicine. Do not stop using the anti-inflammatory medicine even if your asthma seems better, unless you are told to do so by your doctor.

Although this medicine decreases the number of asthma episodes, this medicine may also increase the chances of a severe asthma episode when they do occur. Be sure to read about these risks in the Medication Guide and talk to your doctor or pharmacist about any questions or concerns that you have.

Perforomist® may increase the risk of worsening asthma, which may lead to hospitalization, intubation, and death in patients with asthma who take this medicine without an inhaled steroid medicine. Talk to your doctor if you have concerns about this.

This medicine may cause paradoxical bronchospasm, which means your breathing or wheezing will get worse. Paradoxical bronchospasm may be life-threatening. Check with your doctor right away if you have coughing, difficulty breathing, shortness of breath, or wheezing after using this medicine.

This medicine may cause serious allergic reactions, including anaphylaxis and angioedema, which can be life-threatening and require immediate medical attention. Call your doctor right away if you or your child has a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

Perforomist® may cause heart or blood vessel problems, including heart rhythm problems. Check with your doctor right away if you have chest pain or tightness, decreased urine output, dilated neck veins, extreme fatigue, irregular heartbeat, swelling of the face, fingers, feet, or lower legs, troubled breathing, or weight gain.

Hypokalemia (low potassium in the blood) may occur while you are using this medicine. Check with your doctor right away if you have more than one of the following symptoms: convulsions (seizures), decreased urine, dry mouth, increased thirst, irregular heartbeat, loss of appetite, mood changes, muscle pain or cramps, nausea or vomiting, numbness or tingling in the hands, feet, or lips, shortness of breath, or unusual tiredness or weakness.

This medicine may affect blood sugar levels. If you are diabetic and notice a change in the results of your blood or urine sugar tests, check with your doctor.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

Precautions while using formoterol

It is very important that your doctor check your progress at regular visits to make sure the medicine is working properly. Blood tests may be needed to check for any unwanted effects.

If your symptoms do not improve within a few days or if they become worse, check with your doctor.

Tell your doctor if you are also using other medicines for your COPD. Your doctor may want you to stop using the medicine and use it only during a severe COPD attack. Follow your doctor’s instructions on how you should take your medicine.

This medicine should not be used if you are having a severe COPD attack, or if symptoms of a COPD attack has already started. Your doctor may prescribe another medicine for you to use in case of an acute COPD attack. If the other medicine does not work as well, tell your doctor right away.

This medicine should not be used together with similar inhaled medicines such as arformoterol (Brovana™), budesonide/formoterol (Symbicort®), indacaterol (Arcapta® Neohaler®), salmeterol (Serevent®), or salmeterol/fluticasone (Advair®).

This medicine should only be used as an additional treatment for patients who cannot be treated with other asthma medicines (such as inhaled corticosteroids) or for asthma patients that require two medicines, including formoterol. Ask your doctor if you have any questions.

Talk to your doctor or get medical care right away if:

  • Your or your child’s symptoms do not improve after using this medicine for 1 week or if they become worse.
  • Your short-acting inhaler does not seem to be working as well as usual and you need to use it more often (eg, you use 1 whole canister of your short-acting inhaler in 8 weeks time, or you need to use 4 or more inhalations of your short-acting inhaler for 2 or more days in a row).
  • You have a significant decrease in your peak flow when measured as directed by your doctor.

You or your child may also be using an anti-inflammatory medicine, such as a steroid, together with this medicine. Do not stop using the anti-inflammatory medicine even if your asthma seems better, unless you are told to do so by your doctor.

Although this medicine decreases the number of asthma episodes, this medicine may also increase the chances of a severe asthma episode when they do occur. Be sure to read about these risks in the Medication Guide and talk to your doctor or pharmacist about any questions or concerns that you have.

Perforomist® may increase the risk of worsening asthma, which may lead to hospitalization, intubation, and death in patients with asthma who take this medicine without an inhaled steroid medicine. Talk to your doctor if you have concerns about this.

This medicine may cause paradoxical bronchospasm, which means your breathing or wheezing will get worse. Paradoxical bronchospasm may be life-threatening. Check with your doctor right away if you have coughing, difficulty breathing, shortness of breath, or wheezing after using this medicine.

This medicine may cause serious allergic reactions, including anaphylaxis and angioedema, which can be life-threatening and require immediate medical attention. Call your doctor right away if you or your child has a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

Perforomist® may cause heart or blood vessel problems, including heart rhythm problems. Check with your doctor right away if you have chest pain or tightness, decreased urine output, dilated neck veins, extreme fatigue, irregular heartbeat, swelling of the face, fingers, feet, or lower legs, troubled breathing, or weight gain.

Hypokalemia (low potassium in the blood) may occur while you are using this medicine. Check with your doctor right away if you have more than one of the following symptoms: convulsions (seizures), decreased urine, dry mouth, increased thirst, irregular heartbeat, loss of appetite, mood changes, muscle pain or cramps, nausea or vomiting, numbness or tingling in the hands, feet, or lips, shortness of breath, or unusual tiredness or weakness.

Forteo https://drugonomy.com/2025/12/02/forteo/ https://drugonomy.com/2025/12/02/forteo/#respond Tue, 02 Dec 2025 19:18:54 +0000 https://medicine-21.com/Drugs/?p=8376 Generic name: teriparatide [ ter-i-PAR-a-tide ]
Drug class: Parathyroid hormone and analogs 

What is Forteo?

Forteo is a man-made form of parathyroid hormone that exists naturally in the body. Teriparatide increases bone mineral density and bone strength, which may prevent fractures.

Forteo is used to treat osteoporosis caused by menopause, steroid use, or gonadal failure.

Forteo is for use when you have a high risk of bone fracture due to osteoporosis.

Warnings

Forteo has caused bone cancer (osteosarcoma) in animals but it is not known whether this would occur in people using this medicine. Talk with your doctor about your own risk.

Tell your doctor if you have conditions such as Paget’s disease, high blood levels of calcium or alkaline phosphatase, or a history of bone cancer or radiation treatment involving your bones.

Avoid smoking cigarettes or drinking alcohol. Smoking or heavy drinking can reduce your bone mineral density, making fractures more likely.

Forteo side effects

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

Call your doctor at once if you have:

  • bone pain;
  • new or unusual swelling or lumps under your skin;
  • a light-headed feeling, like you might pass out (may occur within 4 hours after injection);
  • pounding heartbeats or fluttering in your chest after using an injection; or
  • high calcium levels – confusion, muscle weakness, nausea, vomiting, lack of energy, constipation, increased thirst or urination, weight loss.

Common Forteo side effects may include:

  • nausea;
  • joint pain; or
  • pain anywhere in your body.

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

Before taking this medicine

You should not use Forteo if you are allergic to teriparatide.

Forteo is not for use in children or young adults whose bones are still growing.

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

  • Paget’s disease or a bone disease other than osteoporosis;
  • bone cancer or radiation treatment;
  • a genetic condition that increases your risk of bone cancer;
  • overactive parathyroid glands;
  • high blood levels of calcium;
  • a painful skin condition caused by too much calcium;
  • kidney failure;
  • a kidney stone; or
  • an autoimmune disorder such as rheumatoid arthritis, lupus, or psoriasis.

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

It is not known whether teriparatide passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using Forteo.

How should I use Forteo?

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

Forteo is injected under the skin. A healthcare provider may teach you how to properly use the medication by yourself.

Forteo is usually given once per day at the same time each day.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don’t understand all instructions.

Prepare the Forteo injection only when you are ready to give it. Do not use if the medicine looks cloudy, has changed colors, or has particles in it. Call your pharmacist for new medicine.

Your healthcare provider will show you where on your body to inject Forteo. Use a different place each time you give an injection. Do not inject into the same place two times in a row.

Use only the injection pen provided with Forteo. Do not transfer the medicine to a syringe or other injection device or you could get an overdose.

Teriparatide can cause you to feel dizzy or light-headed. Always give your injection at a time and place where you can sit or lie down for a short time afterward.

Each prefilled injection pen contains enough teriparatide for 28 separate injections. Throw the pen away after 28 injections, even if there is still medicine left inside.

Forteo may be only part of a complete treatment program that also includes diet, exercise, taking vitamin or mineral supplements, and changing certain behaviors. Follow your doctor’s instructions very closely.

Store the Forteo injection pen in a refrigerator when not in use. Take the pen out of the refrigerator only long enough to use it. After use, remove the needle, recap the pen, and return it to the refrigerator.

Use a needle and syringe only once and then place them in a puncture-proof “sharps” container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.

Do not freeze Forteo, and throw away the medicine if it has become frozen.

Your doctor will determine how long to treat you with this medicine. Forteo is sometimes given for only 2 years.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line .

Overdose symptoms may include nausea, vomiting, dizziness, headache, feeling light-headed, or fainting.

What should I avoid while using Forteo?

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

Avoid getting up too fast from a sitting or lying position, or you may feel dizzy.

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.

What other drugs will affect Forteo?

Tell your doctor about all your other medicines, especially:

  • digoxin, digitalis.
  • warfarin (Coumadin, Jantoven); or
  • a steroid medicine (such as hydrocortisone, prednisone, methylprednisolone, and others).

Fosamax https://drugonomy.com/2025/11/24/fosamax/ https://drugonomy.com/2025/11/24/fosamax/#respond Mon, 24 Nov 2025 20:23:41 +0000 https://medicine-21.com/Drugs/?p=8369 Generic name: alendronate [ a-LEN-dro-nate ]
Brand names:  Binosto, Fosamax
Drug class: Bisphosphonates 

What is Fosamax?

Fosamax is a bisphosphonate (bis FOS fo nayt) medicine that alters bone formation and breakdown in the body. This can slow bone loss and may help prevent bone fractures.

Fosamax is used in women to treat or prevent osteoporosis caused by menopause and in men and women to treat osteoporosis caused by taking steroids.

Fosamax is also used to increase bone mass in men who have osteoporosis, and to treat Paget’s disease of bone in men and women.

Warnings

You should not take Fosamax if you have problems with your esophagus, or low levels of calcium in your blood.

Do not take Fosamax if you cannot sit upright or stand for at least 30 minutes after taking the medicine.

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

In rare cases, this medicine may cause bone loss (osteonecrosis) in the jaw or a broken leg bone called a femur fracture. Symptoms of osteonecrosis include jaw pain or numbness, red or swollen gums, loose teeth, or slow healing after dental work. Symptoms of a femur fracture include leg or groin pain.

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.

Before taking this medicine

You should not take Fosamax if you are allergic to alendronate, or if you have:

  • low levels of calcium in your blood (hypocalcemia); or
  • problems with the muscles in your esophagus (the tube that connects your mouth and stomach).

Do not take Fosamax if you cannot sit upright or stand for at least 30 minutes. Fosamax can cause serious problems in the stomach or esophagus. You must stay upright for at least 30 minutes after taking this medicine.

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

  • trouble swallowing;
  • problems with your stomach or digestion;
  • low levels of calcium in your blood;
  • a dental problem (you may need a dental exam before you begin taking Fosamax);
  • kidney disease; or
  • any condition that makes it hard for your body to absorb nutrients from food (malabsorption).

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

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

Fosamax has also been reported to cause fractures, or broken bones, in the large bones of the leg. Tell your doctor if you have any leg or groin pain while using Fosamax.

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

It is not known whether Fosamax will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant. Stop using the medicine and tell your doctor right away if you become pregnant.

It is not known whether alendronate passes into breast milk or if it could harm a nursing baby. Ask your doctor about any risk.

How should I take Fosamax?

Take Fosamax exactly as prescribed by your doctor. Fosamax is taken either once daily or once per week. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Take Fosamax first thing in the morning, at least 30 minutes before you eat or drink anything or take any other medicine. If you take this medicine only once per week, take it on the same day each week and always first thing in the morning.

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

Do not crush, chew, or suck on an Fosamax tablet. Swallow the tablet whole.

For at least 30 minutes after taking Fosamax:

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

Pay special attention to your dental hygiene while taking Fosamax. 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 alendronate.

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

Store at room temperature away from moisture and heat.

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

What happens if I miss a dose?

Once-daily dosing: If you forget to take Fosamax 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 dosing: If you forget to take Fosamax 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 schedule on your chosen dose day. Do not take 2 doses in one day.

Furosemide https://drugonomy.com/2025/11/23/furosemide/ https://drugonomy.com/2025/11/23/furosemide/#respond Sun, 23 Nov 2025 20:23:40 +0000 https://medicine-21.com/Drugs/?p=8358 Generic name: furosemide (oral/injection) [ fur-OH-se-mide ]
Brand names: Lasix, Diaqua-2, Lo-Aqua, Furoscix
Dosage forms: oral tablet (20 mg; 40 mg; 80 mg), oral liquid (10 mg/mL), oral solution (40 mg/5 mL)
Drug class: Loop diuretics 

What is furosemide?

Furosemide is a loop diuretic used to treat fluid retention (edema) in people with congestive heart failure, liver disease, or a chronic kidney disorder such as nephrotic syndrome. Furosemide is also used to treat high blood pressure (hypertension).

Furosemide works by increasing the amount of urine the body makes, which helps reduce swelling and symptoms of fluid retention and helps lower high blood pressure. Furosemide tablets are sometimes called water pills as they increase how much you urinate.

Furosemide is also known as frusemide in some countries. Furosemide became an FDA-approved medicine on July 1, 1966, and is available as tablets (Lasix), oral liquid, a subcutaneous injection (Furoscix), and an intravenous solution.

Furosemide side effects

Common furosemide side effects may include:

  • diarrhea, constipation, loss of appetite;
  • numbness or tingling;
  • headache, dizziness; or
  • blurred vision.

Serious furosemide side effects 

Get emergency medical help if you have signs of an allergic reaction to furosemide (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

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

  • a light-headed feeling, like you might pass out;
  • ringing in your ears, hearing loss;
  • muscle spasms or contractions;
  • pale skin, easy bruising, unusual bleeding;
  • high blood sugar – increased thirst, increased urination, dry mouth, fruity breath odor;
  • kidney problems – swelling, urinating less, feeling tired or short of breath
  • signs of liver or pancreas problems – loss of appetite, upper stomach pain (that may spread to your back), nausea or vomiting, dark urine, jaundice (yellowing of the skin or eyes); or
  • signs of an electrolyte imbalance – increased thirst or urination, constipation, muscle weakness, leg cramps, numbness or tingling, feeling jittery, fluttering in your chest.

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

Warnings

You should not use furosemide if you are unable to urinate.

Using more than your recommended dose will not make this medicine more effective. High doses of this medicine may cause irreversible hearing loss.

Before using this medicine, tell your doctor if you have kidney disease, enlarged prostate, urination problems, cirrhosis or other liver disease, an electrolyte imbalance, high cholesterol, gout, lupus, diabetes, or an allergy to sulfa drugs.

Tell your doctor if you have recently had an MRI (magnetic resonance imaging) or any type of scan using a radioactive dye that is injected into your veins. Do not take more of this medication than is recommended.

If you are being treated for high blood pressure, keep using this medicine even if you feel fine. High blood pressure often has no symptoms.

Furosemide is a potent diuretic which, if given in excessive amounts, can lead to a profound diuresis with water and electrolyte depletion. Therefore, careful medical supervision is required and the dose schedule must be adjusted to the individual patient’s needs

Tell your doctor about all your other medicines. Some drugs should not be used with furosemide.

Before taking this medicine

You should not use furosemide if you are allergic to it, are unable to urinate, or have hepatic cirrhosis.
