Merck's second-best selling drug, the bone strengthener Fosamax, has been linked to jaw bone death, a condition that can involve severe pain, infection, loose teeth, exposed bone, loss of function and disfigurement, according to the American Association of Oral and Maxillofacial Surgeons.
And yet sales of the drug remain steady with no decrease whatsoever.
Aside from causing unbearable pain that can not be relieved by ordinary painkillers, osteonecrosis of the jaw (ONJ), can also lead to infections of the face and neck, headaches, bad breath, and difficulty eating. In severe cases, patients may have difficulty breathing or require a feeding tube to avoid malnutrition, according to the July 27, 2006, Sidney Morning Herald.
The debate over the cause of the rise in cases of ONJ picked up speed in 2003, when Dr Robert Marx, chief of oral and maxillofacial surgery at the University of Miami, wrote a paper in the Journal of Oral Maxillofacial Surgery and referred to osteonecrosis of the jaw as "a growing epidemic."
