Fosamax How to Take

Fosamax (Alendronate) belongs to a family of medications known as bisphosphonates. It is used to treat and prevent Osteoporosis for postmenopausal women. It is also used to treat osteoporosis for men.

Fosamax (Alendronate) may also be used to treat and prevent steroid-induced osteoporosis for men and women (osteoporosis caused by taking corticosteroids such as Prednisone for long periods of time). It may also be used to treat Paget's disease of the bone for both men and women.

Fosamax (Alendronate) increases the thickness of bone (bone mineral density) by slowing down the cells that usually break down bone (osteoclasts). This allows the cells that build bone (osteoblasts) to work more efficiently. By making bones stronger, Fosamax (Alendronate) can help to reduce the incidence of osteoporosis-related fractures.

Fosamax (Alendronate) may be available under multiple brand names and/or in several different forms. Any specific brand name of Fosamax (Alendronate) may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Fosamax (Alendronate) may not be used for all of the conditions discussed here.

Your doctor may have suggested Fosamax (Alendronate) for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking Fosamax (Alendronate), speak to your doctor. Do not stop taking Fosamax (Alendronate) without consulting your doctor.

Do not give Fosamax (Alendronate) to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Fosamax (Alendronate) if their doctor has not prescribed it.
