Champix (varenicline)

Back to Resources

Varenicline is a type of medicine that works on the same receptors in the brain that nicotine does. It produces an effect that can relieve your cravings and withdrawal symptoms. Varenicline also blocks nicotine from reacting with the brain, so if you do inhale nicotine, it won’t have any of the rewarding sensations you’ve become accustomed to thereby breaking the reward cycle.
