What is Menostar?

Menostar is a skin patch that contains estradiol, a form of estrogen. Estradiol is a female sex hormone that regulates many processes in the body.

Menostar transdermal skin patches are used to treat certain symptoms of menopause such as hot flashes, and vaginal dryness, burning, and irritation. Menostar is also used to prevent postmenopausal osteoporosis, or to treat ovarian disorders.

Menostar skin patches may also be used for purposes not listed in this medication guide.
