Prempro is a hormone medication used to treat symptoms of menopause, such as vaginal changes and hot flashes. Prempro may also be prescribed to prevent osteoporosis in menopausal women. The main ingredients in Prempro are conjugated estrogens and medroxyprogesterone. Estrogen is a female sex hormone produced by the ovaries and necessary for many essential bodily functions. Progesterone is another female hormone and is responsible for regulating ovulation and menstruation. The mixture in Prempro contains a form of progesterone, which can relieve vaginal dryness, burning, and irritation.

Can I take Prempro while I am pregnant or breastfeeding?
