Chantix is a newly released anti-smoking pill that is nicotine-free and approved by the FDA. Chantix works in two ways, by cutting the pleasure of smoking and reducing the withdrawal symptoms that lead smokers to light up over and over again. Chantix latches on to the same receptors in the brain that nicotine binds to when inhaled in cigarette smoke, an action that leads to the release of dopamine in the pleasure centers of the brain. Taking the drug blocks any inhaled nicotine from reinforcing that effect.

The recommended dosage of Chantix is 0.5mg once a day for the first three days, and then twice a day through the end of the first week of treatment. Then, take 1mg twice daily from days eight to the end of treatment.

This medicine is only intended for adults.
