Raloxifene (raloxifene hydrochloride) — Uses, Dosage, Side Effects & Safety

Drug class: Selective Estrogen Receptor Modulator (SERM)

Overview

Raloxifene is a prescription medication used primarily to prevent and treat osteoporosis (bone thinning) in postmenopausal women. It helps reduce the risk of spinal fractures by mimicking the effects of estrogen on bone, which helps maintain bone density. Raloxifene also lowers the risk of invasive breast cancer in postmenopausal women with osteoporosis or at high risk for breast cancer. It does not treat existing breast cancer or reduce the risk of all types of breast cancer. Key points: Raloxifene is not a hormone, but it acts like estrogen in some tissues (such as bone) and blocks estrogen in others (such as breast and uterus). It is not suitable for use in premenopausal women or men. Patients should be aware of the risk of blood clots and discuss their personal and family medical history with their healthcare provider before starting this medication.
