Raloxifene is used to prevent or treat thinning of the bones (osteoporosis) in women who have already been through menopause (postmenopausal women). Read more about osteoporosis.
Raloxifene is also used to lower chances of having certain type of breast cancer (invasive breast cancer) in women after menopause.
When a woman reaches menopause, the level of the oestrogen hormone goes down. Raloxifene is not an oestrogen hormone but it works by copying the positive effects of oestrogen. It works to slow down bone loss and helps to keep bones strong, making them less likely to break.
