In January 2008, Pfizer added a prominent warning to the label of its smoking-cessation drug Chantix about the potential risks of suicidal behavior, depressed mood and other potential side effects. This came after a November 2007 update to Chantix's "post-marketing experience" section which said there had been reports of depressed mood, agitation, changes in behavior, suicidal ideation and suicide in patients attempting to quit smoking while taking Chantix.
