Pfizer smoking-cessation drug Chantix has been linked to nearly a thousand serious incidents in the last quarter of 2007, the Wall Street Journal reports. A report from a drug safety group found that some users of the drug—already linked to depression and suicide—suffered heart trouble, diabetes, or accidents caused by dizziness and confusion.
The FAA immediately banned pilots and air-traffic controllers from using Chantix and the study's author called for the FDA to update the popular drug's warning label. Pfizer spokesmen said that the current warning already listed the events, classifying them as "rare." The drug company noted that 5.5 million Americans have used the drug.
