A recent study has claimed that Fosamax has a very long life and it remains in the body for many years after its use as a result of which it could lead to permanent impairment bone in the jaw, hip, shoulder or knee as a side effect.

The drug Fosamax was approved by U. S. Food and drug administration (FDA) in October 1995, for the treatment of osteoporosis. The drug is used by more than 20 million people and it belongs to a class of drugs known as bisphosphonates. The drug is manufactured by Merck & Co and the company has reported a sale of over $3 billion.

The drug works by killing the cells of osteoclasts, which break down bone tissues. This process strengthens the bones and reduces the risk of long bone fractures in patients with osteoporosis. The drug remains in the body for many years.

Experts claim that thigh bone breaks are possibly related to the long-term use of Fosamax. People who use Fosamax are at a great risk of the fractures of the femur than those who do not use it. Experts believe that there is clear link between broken bones, and the use of Fosamax.
