Alendronic acid, sold under the brand name Fosamax among others, is a bisphosphonate medication used to treat osteoporosis and Paget's disease of bone.[2] It is taken by mouth.[2] Use is often recommended together with vitamin D, calcium supplementation, and lifestyle changes.[2]
Common side effects include constipation, abdominal pain, nausea, and acid reflux.[2] Serious side effects may include esophageal problems, osteonecrosis of the jaw, and femur fractures.[2] Use is not recommended during pregnancy or in those with poor kidney function.[4] Alendronic acid works by decreasing the activity of cells that break down bone.[2]
Alendronic acid was first described in 1978 and approved for medical use in the United States in 1995.[2][5] It is available as a generic medication.[4] In the United Kingdom, a month of medication costs the NHS about 0.41 pounds as of 2019.[4] In the United States, the wholesale cost is about US$1.16 per month.[6] In 2017, it was the 90th most commonly prescribed medication in the United States, with more than eight million prescriptions.[7][8]
