Reports of suicide and erratic behavior have been associated with the use of Chantix, a medication which is designed to help people stop smoking. Last month the FDA issued a statement that they are reviewing the possible Chantix suicide side effects and that there have been over 100 reports received of suicidal thoughts and severe behavior changes within a few weeks of taking the drug. The lawyers at Saiontz & Kirk, P.A. are evaluating the potential for Chantix lawsuits on behalf of individuals who have committed suicide or suffered severe physical injury as a result of the medication’s behavioral side effects.

>>INFORMATION: Chantix Suicide Side Effects

Chantix (varenicline tartrate) was approved by the FDA in May 2006 as part of a priority review which drastically shortened the time required for the drug maker to begin selling the medication. Chantix helps people quit smoking by easing the symptoms of nicotine withdrawal and by blocking some of the effects of nicotine from cigarettes, which helps promote long term smoking cessation.

In November 2007, the FDA issued an early communication about reports of Chantix suicide thoughts and erratic behavior side effects. They requested data from the drug’s maker, Phizer, Inc., about reported problems involving suicide, aggressive or erratic behavior which could be associated with the medication. Their Chantix investigation is ongoing.

Following the FDA’s inquiry, Pfizer updated the drug’s label on November 20 to indicate that Chantix side effects include “reports of depressed mood, agitation, changes in behavior, suicidal ideation (thoughts) and suicide in patients attempting to quit smoking while taking Chantix.” However, the warnings remain vague, and many believe that Pfizer is still not doing enough to warn users about the potentially life-threatening behavior and mood changes which could be caused by the drug.

In addition to concerns about Chantix suicide side effects, the FDA has also indicated that they are reviewing reports that the medication could cause problems while driving a car or operating heavy machinery. While there were only a small number of reported Chantix driving problems, the FDA pointed out that they all describe a very similar situations with symptoms of drowsiness leading to difficulty while operating a car.


The lawyers at Saiontz & Kirk, P.A. are reviewing potential claims for suicide or severe physical harm which may have been caused by Chantix side effects.
