Medroxyprogesterone is a type of female hormone (progestin). This medication is similar to the progesterone that your body naturally makes and is given to replace the hormone when your body is not making enough of it. This medication has several uses. In women who are not pregnant and not going through menopause, this medication is used to treat abnormal bleeding from the uterus and to restore normal menstrual periods in women who have stopped having them for several months (amenorrhea).
