Why is this medication prescribed?

Raloxifene is in a class of medications called selective estrogen receptor modulators (SERMs). It works by acting similar to estrogen, a female hormone produced by the body. Like estrogen, raloxifene increases the density of bone.

What special precautions should I follow?
Before taking raloxifene,

• tell your doctor and pharmacist if you are allergic to raloxifene or any other drugs.
• tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking. Be sure to mention any of the following: anticoagulants ('blood thinners') such as warfarin (Coumadin), cholestyramine (Questran) or colestipol (Colestid), diazepam (Valium, Valrelease, Zetran), diazoxide (Proglycem), and estrogen or hormone replacement therapy (ERT or HRT). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
