Champix is a medicine that can help you stop smoking. It was only available on prescription. It reduces the cravings for nicotine and helps with the withdrawal symptoms you get when you stop smoking. These can include an urge to smoke again, feeling depressed or irritable, and difficulty sleeping.

If you want to stop smoking, speak to your doctor or NHS stop smoking service. They will be able to advise on other stop smoking treatments, such as nicotine replacement therapy or bupropion (Zyban).
