Chantix® (varenicline)

Chantix is a non-nicotine stop-smoking prescription drug made by Pfizer. Approved in 2006 by the FDA because of its performance during clinical trials, Chantix eases the withdrawal by providing nicotine-like effects and also by blocking the effects of nicotine if the person starts smoking again. Chantix, which was designed to chemically “trick” the nicotine receptor cells in the brain to think that it was getting its “fix” when in fact it was receiving a medication designed to prevent nicotine from binding with those same cells in the future. People who took Chantix were supposed to get the same temporary feeling of pleasure that they got from ingesting nicotine.

Chantix FAQs

Can I file a lawsuit if I have suffered damages from taking Chantix?

Possibly. While all medications have certain, anticipated side effects, a drug manufacturer has a duty to inform physicians adequately regarding the known risks associated with its drugs. If a manufacturer fails to do so, it can be held responsible to patients who are injured as the result of inadequate warnings, under a legal theory known as “product liability.” Depending upon the particular circumstances of your case, damages may include recovery for any of the following:

  • Past and future medical expenses
  • Past and future pain and suffering
  • Lost wages
  • Loss of future earning capacity
  • Emotional distress

If you or a loved one has experienced any health problems while taking Chantix, you should contact your doctor immediately. You may also wish to contact an experienced Chantix lawyer to discuss your legal options. As all legal claims are subject to time limits, however, you may risk forfeiture of your right to financial compensation if you delay.
