What Is Medroxyprogesterone?
Medroxyprogesterone is a prescription hormone medication.
It is a synthetic form of progesterone, a hormone that is naturally made by the body. Medroxyprogesterone is available in several forms, including:
In oral form (tablet form), medroxyprogesterone is used to treat irregular vaginal bleeding and to restore regular menstrual periods in women who have not had a period for several months. It is also used in combination with estrogen in postmenopausal women who have a uterus (have not had a hysterectomy). It is added to estrogen therapy to reduce the risk of
cancer of the uterus.
Injectable forms of medroxyprogesterone are used as long-acting birth control. They are given once every three months.
Medroxyprogesterone subcutaneous injection is also used to relieve the pain from endometriosis. The intramuscular injection is approved to relieve symptoms of advanced endometrial cancer and
kidney cancer.
Medroxyprogesterone is sometimes called medroxyprogesterone acetate, or MPA. The intramuscular injection is sometimes referred to as the "birth control shot."
