How does this medication work? What will it do for me?
Raloxifene belongs to a family of medications called selective estrogen receptor modifiers (SERMs). It is used to treat and prevent osteoporosis in postmenopausal women.
SERMs are not hormones. However, raloxifene acts like estrogen in some parts of the body (including the bones), but not like estrogen in other parts of the body.
Raloxifene works by slowing the breakdown of bone and promoting the building of new bone. Bone density improvements and declines can be detected within one year by a procedure known as a bone mineral density test.
