Nicorette Gum is a nicotine replacement therapy (NRT).
NRT products can be used to relieve withdrawal symptoms and reduce the cravings for nicotine that you get when you try to stop smoking, or when you are cutting down the number of cigarettes you smoke while trying to stop smoking.
To help cut down or quit smoking you should also try to use a behavioural support programme to increase your chances of success.
If you smoke 20 or fewer cigarettes a day, the 2 mg nicotine gum can help relieve your cravings.
If you smoke more than 20 cigarettes a day, 4 mg nicotine gum may be more appropriate.
