What is medroxyprogesterone?
Medroxyprogesterone is a progestin (a form of progesterone), a female hormone that helps regulate ovulation (the release of an egg from an ovary) and menstrual periods.
Medroxyprogesterone is used to treat conditions such as absent or irregular menstrual periods, or abnormal uterine bleeding. Medroxyprogesterone is also used to decrease the risk of endometrial hyperplasia (a condition that may lead to uterine cancer) while taking estrogens.
Medroxyprogesterone is also used to prevent overgrowth in the lining of the uterus in postmenopausal females who are receiving estrogen hormone replacement therapy.
Medroxyprogesterone may also be used for other purposes prescribed by your healthcare professional and not listed above.
What is the most important information you should know about medroxyprogesterone?
You should not use this drug if you are pregnant, or if you have liver disease, a hormone-related cancer such as breast or uterine cancer, a history of stroke or blood clot, or abnormal vaginal bleeding that has not been checked by a medical assistant. Medroxyprogesterone will not prevent heart disease, breast cancer, or dementia, and may actually increase the risk of developing these conditions in post-menopausal women. Medroxyprogesterone may also increase the risk of uterine or ovarian cancer in some females. Long-term treatment with estrogens and progestins (such as medroxyprogesterone) may also increase your risk of heart attack, blood clot, or stroke.
