Alendronate (Fosamax) slows calcium loss from bones. It helps to make normal healthy bone and to slow bone loss in people with
Paget's disease and
osteoporosis. It may be used in others at risk for bone loss. It is more popular than comparable drugs. It is available in generic and brand versions. Generic alendronate is covered by most Medicare and insurance plans, but manufacturer and pharmacy coupons can offset the cost.
