The U.S. Food and Drug Administration announced this week that the diabetes drug Avandia will no longer be available in stores starting in November. The drug is one of the most popular diabetes drugs on the market, but came under fire in 2007 when a study was published that showed “that the drug increased heart attack risk by about 40 percent in people with type 2 diabetes.” Starting November 18th, the drug will only be available through doctors who will be certified to prescribe it and have informed patients of the risks.
