“Chantix (varenicline tartrate) is one of 19 drugs or classes of medications identified by the FDA that showed potential signs of safety issues in the Adverse Event Reporting System (AERS) between October 2008 and December 2008.
Side effects of Chantix are being examined for a possible increased risk of angiodema, serious skin reactions, visual impairment and accidental injury. The FDA indicates that they are evaluating these issues to determine whether there is any need for regulatory action, such as stronger warnings.”
