More Canadians harmed by Chantix as government revises warnings
Health Canada has received 818 reports of adverse side effects caused by the smoking cessation drug Chantix (marketed in Canada and elsewhere as Champix) since it first became available to Canadians nearly two years ago. The majority of complaints concerned psychiatric problems. Chantix is known to cause or exacerbate a spectrum of psychiatric and physical reactions, including moodiness, depression, violent behavior, lack of sleep, blackouts, and suicidal thought and actions.
