Patient Education

Alendronate


Alendronate is used to treat and prevent osteoporosis (a condition in which the bones become thin and weak and break easily) in women who have undergone menopause (''change of life,'' end of menstrual periods) and to treat osteoporosis in men. Alendronate is also used to treat osteoporosis in men and women who are taking corticosteroids (a type of medication that may cause osteoporosis in some patients). Alendronate is also used to treat Paget's disease of bone (a condition in which the bones are soft and weak and may be deformed, painful, or easily broken). Alendronate is in a class of medications called bisphosphonates. It works by preventing bone breakdown and increasing bone density (thickness).
