EVOREL 100 is a type of hormone replacement therapy (HRT) patch that is primarily used to alleviate symptoms associated with menopause, such as hot flashes, night sweats, mood swings, and vaginal dryness. It contains estradiol, a form of estrogen, which is a natural hormone that decreases in the body during menopause. By delivering a steady dose of estradiol through the skin into the bloodstream, EVOREL 100 helps to replenish estrogen levels, thereby reducing menopausal symptoms. The patch is designed for transdermal use, meaning it is applied directly to the skin, typically on the lower abdomen or buttocks, and is usually replaced twice a week. It is important for users to follow their healthcare provider's instructions regarding the use of EVOREL 100, as hormone replacement therapy may not be suitable for everyone and can have potential side effects.
