NRT is a medicine that provides you with a low level of nicotine, without the tar, carbon monoxide and other poisonous chemicals present in tobacco smoke.
It can help reduce unpleasant withdrawal effects, such as bad moods and cravings, which may occur when you stop smoking.
Where to get it and how to use it
NRT can be bought from pharmacies and some shops. It’s also available on prescription from a doctor or NHS Stop Smoking Service.
It’s available as:
- skin patches
- chewing gum
- inhalators (which look like plastic cigarettes)
- tablets, oral strips and lozenges
- nasal and mouth spray
Patches release nicotine slowly. Some are worn all the time and some should be taken off at night. Inhalators, gum and sprays act more quickly and may be better for helping with cravings.
There’s no evidence that any single type of NRT is more effective than another. But there is good evidence to show that using a combination of NRT is more effective than using a single product.
Often the best way to use NRT is to combine a patch with a faster acting form such as gum, inhalator or nasal spray.
Treatment with NRT usually lasts 8-12 weeks, before you gradually reduce the dose and eventually stop.
Who can use it
You can usually use NRT if you’re:
- over 12 years old – although children under 18 should not use the lozenges without getting medical advice first
- pregnant – your doctor may suggest NRT if they think it would help you stop; read more about stopping smoking in pregnancy
- breastfeeding – your doctor can advise you how to do this safely
Always read the packet or leaflet before using NRT to check whether it’s suitable for you.
Sometimes it may be advisable to get medical advice first, for example if you have kidney or liver problems, or you’ve recently had a heart attack or stroke.
