What is medroxyprogesterone?
Medroxyprogesterone is a form of progesterone, a female hormone that prevents ovulation (the release of an egg from an ovary). This medicine also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.
Medroxyprogesterone is used as contraception to prevent pregnancy. It is also used to reduce pain caused by endometriosis.
Medroxyprogesterone is also used to ease pain and other symptoms in women with metastatic uterine or kidney cancer. This medicine is not a cure for these conditions.
Medroxyprogesterone may also be used for purposes not listed in this medication guide.
Medroxyprogesterone can cause birth defects. Do not use if this medicine if you are pregnant. Tell your doctor right away if you become pregnant during or soon after treatment with medroxyprogesterone.
You should not use this medicine for longer than 2 years. Medroxyprogesterone can decrease the calcium stored in your bones, which may cause bone loss (osteoporosis).
