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 women who are receiving estrogen hormone replacement therapy
You should not use medroxyprogesterone 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 doctor.
Medroxyprogesterone should not be used to prevent heart disease, stroke, or dementia. This medicine may actually increase your risk of developing these conditions. Long-term use of medroxyprogesterone may increase your risk of breast cancer, heart attack, stroke, or blood clot. Talk with your doctor about your individual risk.
