Is there a link between Fosamax and femur fractures?
March 9th, 2010Can Fosamax (the popular osteoporosis drug) cause more harm than good? That’s a question viewers of ABC’s Good Morning America are asking themselves after watching a report on the show this morning. A new study set to be released this week says that the drug Fosamax, designed to help strengthen bones, could cause a weakening of the bones as a side effect when taken for an extended period of time (meaning over the course of more than five years).
In 2008 the FDA contacted the manufacturer of the drug about reports of femur fractures happening in women who took this popular drug. Merck (the maker of Fosamax) has added femur fractures as a possible side effect in the literature included in the patient information in the drug package.
Fosamax is part of a class of drugs known as bisphosphonates. These drugs have been proven to help prevent hip and spine fractures in many patients. Doctors do agree that the possible dangers of fractures of the hip and spine that can occur in patients with osteoporosis are a problem and the chance of these fractures and the associated side effects of them (including death) must be weighed against any potential side effects of the drugs. While there is no conclusive research on the length of time a patient can safely take this class of drugs, doctors recommend that patients not take it for more than five years.
