Estrogens may increase the risk of cancer of the uterus (endometrial cancer). If you have a uterus, ask your doctor if taking a progestin can help decrease your risk. Tell your doctor right away if you have any unusual vaginal bleeding.
This medication is used to treat menopause symptoms. It helps reduce episodes of flushing and sweating of the upper body and face, commonly called hot flashes. It also helps treat dryness, itching, and burning around the vagina. These symptoms occur when a woman's body no longer produces the usual amount of hormone (estrogen) at the age when monthly menstrual periods normally stop. This medication is a combination of 2 hormones, estrogen and methyltestosterone.
If you need treatment only for vaginal menopause symptoms, products applied directly inside the vagina should be considered before medications that are taken by mouth, absorbed through the skin, or injected.
