Patient Education

Estradiol Transdermal Patch


Most brands of estradiol transdermal patches are used to treat hot flushes (hot flashes; sudden strong feelings of heat and sweating) and/or vaginal dryness, itching, and burning in women who are experiencing menopause (change of life; the end of monthly menstrual periods). Transdermal estradiol is also used to prevent osteoporosis (a condition in which the bones become thin and weak and break easily) in women who are experiencing or have experienced menopause. Women who need to use transdermal estradiol for more than one of these reasons can benefit most from the medication. Women whose only bothersome symptoms are vaginal dryness, itching, or burning may benefit more from an estrogen product that is applied topically to the vagina. Women who only need a medication to prevent osteoporosis may benefit more from a different medication that does not contain estrogen. Most brands of estradiol transdermal patches are also sometimes used as a source of estrogen in young women who do not produce enough estrogen naturally. Estradiol is in a class of medications called estrogen hormones. It works by replacing estrogen that is normally produced by the body. Menostar® brand patches contain less estrogen than other brands of estradiol transdermal patches. Menostar® patches are used only to prevent osteoporosis in women who are experiencing or have experienced menopause.
