Another reason to adhere to the "two year" rule

Federal health officials are warning doctors and patients that a recently-launched heart drug from Sanofi-Aventis SA has been linked to liver damage in a handful of patients. The Food and Drug Administration said Friday it has received several reports of liver damage with Multaq tablets, including two cases in which patients had to have their livers removed. Both patients were women and roughly 70 years old. They had been taking the drug for 4.5 months and 6 months, respectively. The FDA approved Multaq in July 2009 to treat atrial flutter and atrial fibrillation which are irregular heart rhythms that can reduce blood flow and lead to stroke. More than a half-million prescriptions for Multaq have been written since the drug was approved.

In an online notice, the FDA said it would add a new warning about the risk for liver damage to the label of Multaq. The agency said patients should contact their doctor if they experience signs of liver injury, including nausea, vomiting and fever. If doctors suspect a toxicity issue they should discontinue use of the drug and test the patient's liver enzymes.
