Estradiol is a form of estrogen, a female sex hormone that regulates many processes in the body. Estradiol transdermal skin patches are used to treat certain symptoms of menopause such as hot flashes, and vaginal dryness, burning, and irritation. This medication is also used to prevent postmenopausal osteoporosis, or to treat ovarian disorders. Estradiol transdermal may also be used for purposes not listed in this medication guide.
Menostar is used by women to reduce symptoms of menopause. Estradiol, its active ingredient, is a hormone naturally produced in the female body by the ovaries that regulates a number of bodily functions. These hormones naturally begin to drop off during menopause, which results in many issues such as hot flashes and vaginal dryness. Artificially increasing the levels of this hormone naturally decreases many of those effects.
