Merck is being sued for Fosamax:
According to a lawsuit filed Monday in federal court in Fort Myers, Fosamax is a defective product because it can cause osteonecrosis of the jaw, or a rotting of the jaw bone. The suit, which seeks class-action status, alleges Merck concealed and continues to hide Fosamax’s potentially dangerous side effects from patients and doctors.
The cases of osteonecrosis of the jaw are associated with cancer patients requiring intravenous bisphosphonates. Fosamax is generally quite safe – osteonecrosis of the jaw with this medication is a rare, rare occurrence. (via PharmaGossip)
