About Fosamax

Fosamax (alendronate), a biphosphonate medication, helps treat osteoporosis. It works to slow down osteoclasts to slow bone loss and prevent bone fractures.

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

There are several FDA-approved uses for Fosamax, but your healthcare provider may also prescribe it off-label to treat other medical conditions.

 

Your PlushCare doctor may prescribe Fosamax for any of the following reasons, or other reasons not listed here. Ask your online doctor or pharmacist if you have questions about why a medication is prescribed.

Osteoporosis

Fosamax is FDA-approved to treat osteoporosis. Fosamax can help prevent bone loss in postmenopausal women, increase bone mass in men with osteoporosis, and treat glucocorticoid-induced osteoporosis.

Paget's disease of bone

Fosamax is FDA-approved to treat Paget's disease of bone. Paget's disease of bone interferes with the body's normal bone formation process, causing bones to become fragile. Fosamax helps slow bone turnover and prevent bone fractures.
