Drug NameEvista (Raloxifene) Drug UsesEvista is used to prevent and treat bone loss (osteoporosis) in women after menopause. Maintaining strong bones by slowing bone loss helps to reduce the risk of fractures. This drug is different from hormones (including estrogens and progestins). It works by acting like estrogen (as a selective estrogen receptor modulator or SERM) in some parts of the body. Evista helps to preserve bone mass, but it does not affect the breast and uterus like estrogen or relieve symptoms of menopause such as hot flashes. This medication is not recommended for use in women before menopause. It should not be used in children. How TakenTake this medication by mouth usually once a day, with or without food, or as directed by your doctor. Use this medication regularly to get the most benefit from it. Remember to use it at the same time each day. Be sure to include adequate amounts of calcium and vitamin D in your diet. Consult your doctor or pharmacist to see if you need to take calcium/vitamin D supplements. This medication comes with a patient information leaflet. Read it carefully. Ask your doctor or pharmacist any questions you may have. Drug Class and MechanismEstrogen is a hormone which among other actions, regulates the turnover (formation and destruction) of bone. Decreases in estrogen levels that are seen after menopause or after removal of the ovaries, lead to a loss of bone density and weakened bones, a condition called osteoporosis. Evista decreases bone turnover and increases bone density although not to the same extent as estrogen itself. This makes bones stronger and prevents fractures in women with osteoporosis. Evista is called a "selective estrogen receptor modulator" since it has effects like estrogen on some tissues but inhibits the effects of estrogen on other tissues. Evista decreases low density lipoprotein (LDL or "bad") cholesterol in the blood; however, unlike estrogen, evista does not increase high density lipoprotein (HDL or "good") cholesterol.

More Information
Do not share this medication with others. Keep all appointments with your doctor and the laboratory. You should have a complete physical examination, breast and pelvic examination, and PAP test (for vaginal cancer) at least once a year. You should also have periodic mammograms as determined by your doctor. Follow your doctor's instructions for examining your own breasts. Report any unusual vaginal bleeding, breast pain, or lumps immediately. Lifestyle changes that help promote healthy bones include increasing weight-bearing exercise, eating well-balanced meals that contain adequate calcium and vitamin D, stopping smoking, and limiting alcohol. Consult your doctor about lifestyle changes that might benefit you. Laboratory and/or medical tests (bone density tests, x-rays, height measurement, blood mineral levels) should be performed periodically to monitor your progress or check for side effects. Consult your doctor for more details.
