What is Fosamax Plus D?

Fosamax Plus D contains a combination of alendronate and cholecalciferol. Alendronate is a bisphosphonate medicine that alters bone formation and breakdown in the body. This can slow bone loss and may help prevent bone fractures.

Cholecalciferol is a form of vitamin D, and is important for the absorption of calcium from the stomach and for the functioning of calcium in the body.

Fosamax Plus D is used to treat and prevent osteoporosis.

Fosamax Plus D may also be used for purposes not listed in this medication guide.

Do not take a Fosamax Plus D tablet if you cannot sit upright or stand for at least 30 minutes. Alendronate can cause serious problems in the stomach or esophagus (the tube that connects your mouth and stomach). You will need to stay upright for at least 30 minutes after taking Fosamax Plus D.
