WHY is this medicine prescribed?
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 and vaginal dryness. Ospemifene is in a class of medications called hormones. It works by replacing estrogen that is normally produced by the body.
HOW should this medicine be used?
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 vaginal dryness and 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.

What should I know about STORAGE and DISPOSAL of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (https://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location — one that is up and away and out of their sight and reach. https://www.upandaway.org
