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.
