Ospemifene is used to treat changes due to menopause (''change of life,'' the end of monthly menstrual periods) in and around the vagina that can cause painful sexual intercourse. Ospemifene is in a class of medications called hormones. It works by replacing estrogen that is normally produced by the body.
Ospemifene comes as a tablet to take by mouth. It is usually taken with food once daily. Take ospemifene at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ospemifene exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Ospemifene helps to control the symptoms of menopause that can cause pain during intercourse but does not cure it. Continue to take ospemifene even if you feel well. Do not stop taking ospemifene without talking to your doctor.
