Chemical Name: MEDROXYPROGESTERONE (me-DROX-ee-proe-JESS-te-rone)
Medroxyprogesterone is a progestin used to treat menstrual disorders. Medroxyprogesterone may also be used to treat other conditions as determined by your doctor. Progestins lower the risk of estrogen-related cancer of the uterus. Medroxyprogesterone used in combination with estrogen (hormone replacement therapy - HRT) should not be used to prevent heart disease.
WARNING: Two-drug combination hormone replacement therapy (estrogen and progestin menopause HRT) can infrequently cause cancer of the breast, heart disease (e.g., heart attack), stroke, dementia, or blood clots in the lung (pulmonary embolism) or leg. Estrogens may also increase the risk of cancer of the ovary. These risks appear to depend on the length of time this combination is used and the amount of estrogen per dose. Therefore, two-drug HRT should be used for the shortest possible length of time at the lowest effective dose, so you obtain the benefits and minimize the chance of serious side effects from long-term treatment. Discuss the risks and benefits with your doctor. If you use Medroxyprogesterone for an extended period, you should be evaluated at least once a year. See Caution section. Blood clots may be more likely to form during very long periods of sitting or if you are bedridden, as well as with certain types of surgery. If this applies to you, ask your doctor whether you should temporarily stop Medroxyprogesterone. You should not use Medroxyprogesterone during the first 4 months of pregnancy because birth defects may occur. Medroxyprogesterone has not been proven to prevent natural abortions that occur early in the pregnancy. Often, the cause of an early natural abortion is due to a defective female egg. Using Medroxyprogesterone does not fix a defective egg and may get in the way of expelling it. Some medicines or medical conditions may interact with Medroxyprogesterone. INFORM YOUR DOCTOR OR PHARMACIST of all prescription and over-the-counter medicine that you are taking. Some medicines or medical conditions may interact with this medicine.

ADDITIONAL MONITORING OF YOUR DOSE OR CONDITION may be needed if you are taking rifampin. USE OF Medroxyprogesterone IS NOT RECOMMENDED if you have a history of pulmonary embolism.

IT IS IMPORTANT that you keep all doctor and laboratory appointments while you are taking Medroxyprogesterone.
