Raloxifene, sold under the brand name Evista among others, is a medication used to prevent and treat osteoporosis in postmenopausal women and those on glucocorticoids.[6] For osteoporosis it is less preferred than bisphosphonates.[6] It is also used to reduce the risk of breast cancer in those at high risk.[6] It is taken by mouth.[6]

Common side effects include hot flashes, leg cramps, swelling, and joint pain.[6] Severe side effects may include blood clots and stroke.[6] Use during pregnancy may harm the baby.[6] The medication may worsen menstrual symptoms.[7] Raloxifene is a selective estrogen receptor modulator (SERM) and therefore a mixed agonist–antagonist of the estrogen receptor (ER).[6] It has estrogenic effects in bone and antiestrogenic effects in the breasts and uterus.[6]

Raloxifene was approved for medical use in the United States in 1997.[6] It is available as a generic medication.[6][8] In 2020, it was the 292nd most commonly prescribed medication in the United States, with more than 1 million prescriptions.[9][10]
