This medication is a female hormone (estrogen). It is absorbed through the skin and enters into the bloodstream. It is used by women to help reduce a certain symptom of menopause (hot flashes). Symptoms of menopause are caused by the body making less estrogen. If you are using estrogens to treat only vaginal symptoms of menopause (such as vaginal dryness/burning/itching), products applied directly inside the vagina should be considered before medications that are taken by mouth, absorbed through the skin, or injected.
