What Is Raloxifene and How Does It Work?

Raloxifene is a prescription drug used by women to prevent and treat bone loss (osteoporosis) after menopause. It slows down bone loss and helps to keep bones strong, making them less likely to break.

Raloxifene may also lower the chance of getting a certain type of breast cancer (invasive breast cancer) after menopause.

Raloxifene is not an estrogen hormone, but it acts like estrogen in some parts of the body, like your bones. In other parts of the body (uterus and breasts), raloxifene acts like an estrogen blocker. It does not relieve menopause symptoms such as hot flashes. Raloxifene belongs to a class of drugs known as selective estrogen receptor modulators-SERMs.

Raloxifene should not be used before menopause.

Raloxifene should not be used to prevent heart disease.

Raloxifene is available under the following different brand names: Evista.
