Fosamax was approved in 1995 for treatment of osteoporosis and Paget’s disease of the bone.  It has been heavily marketed by Merck, who has encouraged users to stay on the medication for years. However, research suggests that long-term use increases the risk of serious and potentially debilitating side effects of Fosamax.

Fosamax works by preventing bone turnover, to reduce the risk of fractures associated with osteoporosis. However, the side effects of long-term use could prevent blood flow to the bones, resulting in a gradual decay or death of certain bones over time.

In 2006, the first lawsuits over Fosamax jaw problems were filed on behalf of individuals diagnosed with osteonecrosis of the jaw. Side effects of Fosamax were found to prevent the turnover of the jaw bone, which could cause a painful and potentially disfiguring condition where the jaw bone deteriorates and dies. Complications may result in jaw infections and exposed bone inside the mouth.

Studies have also suggested that Fosamax may increase the risk of decay and death of other bones, including the hip, knees or shoulder. This could result in joint pain, limited mobility and loss of function within the joint.

In 2008, research suggested a potential connection between Fosamax and femur fractures that typically occur spontaneously, with little or no trauma at all. Long-term users of Fosamax have reportedly suffered sudden femur fractures while taking a step or after falling from a standing height or less. It is believed that by preventing bone turnover, side effects of Fosamax prevent small micro-fractures from healing themselves, which can ultimately lead to a complete bone fracture.


The lawyers at Saiontz & Kirk, P.A. represent individuals throughout the United States who are pursuing a Fosamax lawsuit against Merck as a result of their failure to adequately research the side effects of their popular medication or warn about the risk of bone problems.

Although it appears the the drug maker knew or should have known that Fosamax side effects could increase the risk of problems the longer the medication is used, Merck failed to provide information to consumers and the medical community that could have allowed users to reduce the risk.

If you or a family member have taken Fosamax and suffered a sudden femur fracture on Fosamax or been diagnosed with osteonecrosis of the jaw, osteonecrosis of the hip, osteonecrosis of the knee or osteonecrosis of the shoulder after using Fosmomax for a long period of time, request a free consultation to review your legal rights. All claims were investigated by our law firm under a contingency fee agreement, which means that there are no fees or expenses unless a recovery is obtained for problems caused by the effects of Fosamax.
