Estrace tablets contains estradiol, a form of estrogen. Estradiol is a female sex hormone produced by the ovaries that regulates many processes in the body.
Estrace is used to treat symptoms of menopause such as hot flashes, and vaginal dryness, burning, and irritation. Other uses include prevention of osteoporosis in postmenopausal women, and replacement of estrogen in women with ovarian failure or other conditions that cause a lack of natural estrogen in the body. Estrace is sometimes used as part of cancer treatment in women and men.
Estrace is also available as a cream.
