Since 2004, drug manufacturer Merck has dealt with thousands of lawsuits dealing with its painkiller drug Vioxx, which has been linked to heart attacks, strokes and death. Now, the same drug maker is facing more lawsuits due to its prescription drug Fosamax, which millions are now taking for osteoporosis. Fosamax has been tied to a serious condition called Osteonecrosis of the Jaw or ‘Dead Jaw.’ Now those victims of dead jaw are lining up to file lawsuits against Merck.
