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.
