Stop-smoking drug stops more than smoking

A lawsuit was just filed against drug maker Pfizer blaming the company for causing a murder-suicide in Pennsylvania in May 2009. The lawsuit contends that Pfizer’s smoking-cessation drug Chantix caused user Sean Wain to fly into a rage and shoot his wife to death before turning the gun on himself. Wain had been taking Chantix, a prescription medication, for about a week or two prior to the murder-suicide. The couple had four children.

The lawsuit was filed by the fathers of the deceased. It alleges that Pfizer was negligent in warning consumers of side effects of hostility and aggression and suicidal tendencies. Apparently these side effects surfaced during clinical trials. Chantix was approved by the Food and Drug Administration (FDA) in May 2007, but about a year and a half later the FDA announced it would investigate negative reports from Chantix users that alleged the drug caused mood swings and behavioral changes. In July 2009 the FDA required Pfizer to print a warning on the drug.
