Overview
Champix (Varenicline) is a prescription medication used to help people quit smoking. It works by reducing cravings and withdrawal symptoms associated with quitting smoking. Varenicline, the active ingredient, works by partially stimulating nicotine receptors in the brain while also blocking nicotine from attaching to those receptors. This dual action reduces both the pleasurable effects of smoking and the symptoms of nicotine withdrawal, making it easier for individuals to quit smoking.
