What is progesterone (First Progesterone MC10, First Progesterone MC5, Progest, Prometrium)?

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 should not be used to prevent heart disease or dementia, because this medication may actually increase your risk of developing these conditions.

Progesterone may also be used for other purposes not listed in this medication guide.
