About Fosamax
Fosamax is only available by prescription. It is available under the generic name alendronate.
Fosamax is prescribed as a tablet. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage prescribed.
If you're prescribed Fosamax, complete the entire course of bisphosphonate therapy unless your doctor specifically tells you to stop. If you don’t complete your osteoporosis treatment, the bisphosphonate may not fully treat your osteoporosis.
Fosamax uses
