How does Champix work?

Champix is designed to do two things:

  1. Help reduce cravings and withdrawal symptoms that happen when you give up smoking.

  2. Block the effect of nicotine.

  • When you smoke cigarettes, nicotine binds to receptors in your brain, which triggers the release of a feel-good chemical messenger called dopamine.
  • Shortly after you’ve had a smoke, nicotine and dopamine levels start to drop so you get craving and withdrawal feelings, making you want another cigarette.
  • Champix is believed to work by activating the same receptors in the brain and blocking nicotine from attaching and activating them.
  • This can help you to have fewer cravings and withdrawal symptoms from smoking and reduce your enjoyment of cigarettes if you do smoke while on treatment

How does Champix make quitting easier?

If you’re ready to quit smoking, Champix can help make it easier in two ways:

  1. It helps reduce the cravings and withdrawal symptoms that happen when you give up smoking.
  2. It blocks the effect of nicotine, so if you do smoke while on Champix, it won’t be so enjoyable.
