The uses of OSTEOFOS include: 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).
Alendronate comes as a tablet and a solution (liquid) to take by mouth. The solution is usually taken on an empty stomach once a week in the morning. The 5-mg and 10-mg tablets are usually taken on an empty stomach once a day in the morning, and the 35-mg and 70-mg tablets are usually taken on an empty stomach once a week in the morning. The 40-mg tablets are usually taken once a day in the morning for six months to treat Paget's disease of bone.
Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take alendronate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
