What is estradiol and norgestimate?

Estradiol is a female sex hormone that is involved in the development and maintenance of the female reproductive system.

Norgestimate is a form of progesterone. Progesterone is a female hormone important for the regulation of ovulation and menstruation.

Together, estradiol and norgestimate are used to treat the symptoms of menopause such as feelings of warmth in the face, neck and chest, or sudden intense spells of heat and sweating ("hot flashes” or "hot flushes”); to treat vulvar and vaginal changes (itching, burning, dryness in or around the vagina, difficulty or burning with urination) caused by menopause; and to prevent thinning of the bones (osteoporosis).

Estradiol and norgestimate may also be used for purposes other than those listed in this medication guide.
