Fosamax (Alendronate) is a bisphosphonate used to prevent and
treat osteoporosis in women and men by reducing calcium loss from
bones. It helps prevent bone loss and increases production of normal
healthy bone in patients with osteoporosis, Paget's disease, and other
conditions which cause a risk for bone loss, including post menopausal
women and after the long-term use of corticosteroids (like prednisone) in men or women.
