  1. About Chantix

    • For most people, Chantix is a safe medication to help quit smoking. Chantix is also called varenicline and is manufactured by Pfizer.

    How Chantix Works

    • Chantix cuts off the effects of nicotine on the brain. At the same time, it allows the release of small amounts of the chemicals that make smoking pleasurable into the brain. Chantix lessens dependence and weakens smoking withdrawal symptoms.

    FDA Public Health Advisory

    • In 2008, the U.S. Food and Drug Administration issued a Public Health Advisory on Chantix. The advisory was issued because of psychiatric side effects suffered by some people using Chantix. The drug was also reported to revive earlier psychiatric problems individuals had suffered.
