Smoking Drug Chantix® Linked to Depression, Suicidal Behavior

The anti-smoking drug Chantix® has been linked to depression, suicidal thoughts, and violent behavior in some users, according to the Food and Drug Administration (FDA) (1). Government scientists are currently investigating the matter after reports of mood disorders and erratic behavior in some users came to their attention earlier this year.

According to researchers, hundreds of patients taking Chantix have reported serious accidents, vision problems, and heart trouble.

The FAA then prohibited its pilots from using Chantix because of its possible dangers, which also include blurred vision, dizziness, confusion, loss of consciousness, and a previously established link to suicidal behavior (source).

Chantix is a prescription drug designed to help adults quit smoking. It comes in a white tablet (0.5mg) and a blue tablet (1mg) and is usually taken for 12 weeks at a time (2).

Chantix may be dangerous to some users. The FDA issued a report that stated, “A preliminary assessment reveals that many of the cases reflect new-onset of depressed mood, suicidal ideation, and changes in emotion within days to weeks of initiating Chantix treatment (1).” Some of the patients who have been adversely affected by Chantix had no history of psychiatric illness and had not quit smoking when they experienced suicidal thoughts.

Update 1/18/08: Chantix will carry more prominent warnings that patients should be monitored for unusual activity including agitation, depression and suicidal behavior. The new warnings will be featured prominently on the anti-smoking drug’s labeling.
