Uses For raloxifene
Raloxifene is used to help prevent and treat thinning of the bones (osteoporosis) only in postmenopausal women.
It works like an estrogen to stop the bone loss that can develop in women after menopause, but it does not increase the bone density as much as daily 0.625 mg doses of conjugated estrogens. Raloxifene will not treat hot flashes of menopause and may cause hot flashes to occur. Also, raloxifene does not stimulate the breast or uterus as estrogen does.
Raloxifene lowers the blood concentrations of total and low-density lipoprotein (LDL) cholesterol, the bad cholesterols, but it does not increase concentrations of high-density lipoprotein (HDL) cholesterol, the good cholesterol, in your blood.
Raloxifene is also used to lower chances of having invasive breast cancer in postmenopausal women with osteoporosis or at high risk of having invasive breast cancer .
raloxifene is available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, raloxifene is used in certain patients with the following medical conditions:

The doctor may have you start the medicine again after you are back on your feet and fully mobile. If you are going on a trip and stay on raloxifene, you should walk regularly or move about when possible.
