Prometrium is used to cause menstrual periods in women who have not yet reached menopause but are not having periods due to a lack of progesterone in the body. This medicine is also used to prevent overgrowth in the lining of the uterus in postmenopausal women who are receiving estrogen hormone replacement therapy.
