Progesterone is a female hormone important for the regulation of ovulation and
menstruation.
Progesterone 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. Progesterone is
also used to prevent overgrowth in the lining of the uterus in postmenopausal women who are
receiving estrogen hormone replacement therapy.
Progesterone may also be used for other purposes not listed in this medication guide.
