Megestrol

Megestrol 

En Español (Spanish Version)

(me jes' trol)

WHY is this medicine prescribed?

Megestrol tablets are used to relieve the symptoms and reduce the suffering caused by advanced breast cancer and advanced endometrial cancer (cancer that begins in the lining of the uterus). Megestrol suspension is used to treat loss of appetite, malnutrition, and severe weight loss in patients with acquired immunodeficiency syndrome (AIDS). Megestrol should not be used to prevent loss of appetite and severe weight loss in patients who have not yet developed this condition. Megestrol is a man-made version of the human hormone progesterone. It treats breast cancer and endometrial cancer by affecting female hormones involved in cancer growth. It increases weight gain by increasing appetite.

HOW should this medicine be used?

Megestrol comes as a tablet, a suspension (liquid), and a concentrated suspension (Megace ES) to take by mouth. The tablets and suspension are usually taken several times a day. The concentrated suspension is usually taken once a day. Take megestrol at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take megestrol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Shake the liquid well before each use to mix the medication evenly.

The concentrated suspension is used in different dosages than the regular suspension. Do not switch from one to the other without talking to your doctor.

Do not stop taking megestrol without talking to your doctor.

Are there OTHER USES for this medicine?

Megestrol is also sometimes used to treat malnutrition in patients with cancer, prostatic hypertrophy (enlargement of a male reproductive gland called the prostate), endometriosis (condition in which the type of tissue that lines the uterus grows in other areas of the body), and endometrial hyperplasia (overgrowth of the lining of the uterus). Talk to your doctor about the risks of using this medication for your condition.

What SPECIAL PRECAUTIONS should I follow?

Before taking megestrol,

  • tell your doctor and pharmacist if you are allergic to megestrol, any other medications, or any of the inactive ingredients in megestrol tablets, suspension, or concentrated suspension. Ask your doctor or pharmacist for a list of the inactive ingredients.
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention antibiotics and indinavir (Crixivan). Your doctor may need to adjust the doses of your medications or monitor you carefully for side effects.
  • tell your doctor if you have or have ever had a blood clot anywhere in the body, a stroke, diabetes, or kidney or liver disease.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking megestrol, call your doctor immediately. Megestrol may harm the fetus. Do not breast-feed while you are taking megestrol.
  • you should know that megestrol may interfere with the normal menstrual cycle (period) in women. However, you should not assume that you cannot become pregnant. Use a reliable method of birth control to prevent pregnancy.

Unless your doctor tells you otherwise, continue your normal diet.
