If you want to stop smoking, several different treatments are available from shops, pharmacies and on prescription to help you beat your addiction and reduce withdrawal symptoms.
The best treatment for you will depend on your personal preference, your age, whether you're pregnant or breastfeeding and any medical conditions you have. Speak to your GP or an NHS stop smoking adviser for advice.
Research has shown that all these methods can be effective. Importantly, evidence shows that they are most effective if used alongside support from an NHS stop smoking service.
The main reason that people smoke is because they are addicted to nicotine.
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.
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:
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.
You can usually use NRT if you're:
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.
Side effects of NRT can include:
Any side effects are usually mild. But if they're particularly troublesome, contact your GP as the dose or type of NRT may need to be changed.
Varenicline (which used to be called Champix) is a medicine that works in 2 ways. It reduces cravings for nicotine like NRT, but it also blocks the rewarding and reinforcing effects of smoking.
Evidence suggests it's the most effective medicine for helping people to stop smoking.
Varenicline is only available on prescription, so you'll usually need to see your GP or contact an NHS stop smoking service to get it.
It's taken as 1 to 2 tablets a day. You should start taking it a week or 2 before you try to quit.
A course of treatment usually lasts around 12 weeks, but it can be continued for longer if needed.
Most people can take varenicline, although there are some situations where it's not recommended. For example, it's not suitable:
Side effects of varenicline can include:
Speak to your GP if you have any problems with side effects.
Bupropion (brand name Zyban) is a medicine originally used to treat depression, but it has since been found to help people quit smoking.
It's not clear exactly how it works, but it's thought to have an effect on the parts of the brain involved in addictive behaviour.
Bupropion is only available on prescription, so you'll usually need to see your GP or contact an NHS stop smoking service to get it.
It's taken as 1 to 2 tablets a day. You should start taking it a week or 2 before you try to quit.
A course of treatment usually lasts around 7 to 9 weeks.
Most people can take bupropion, but there are some situations when it's not recommended. For example, it's not suitable if you:
Side effects of bupropion can include:
Speak to your GP if you have any problems with side effects.
Serotonin syndrome is an uncommon, but potentially serious, set of side effects linked to some medicines. It happens when the levels of a chemical called serotonin in your brain become too high.
There's a risk of serotonin syndrome if you take more than your prescribed dose of bupropion, or if you take certain other medicines with bupropion such as:
Contact your GP or NHS 111 if you have any symptoms of serotonin syndrome, including:
You can call 111 or get help from 111 online.
An e-cigarette is an electronic device that delivers nicotine in a vapour. This allows you to inhale nicotine without most of the harmful effects of smoking, as the vapour contains no tar or carbon monoxide.
Research has found that e-cigarettes can help you give up smoking, so you may want to try them rather than the medicines listed above. As with other approaches, they're most effective if used with support from an NHS stop smoking service.
There are no e-cigarettes currently available on prescription.
For now, if you want to use an e-cigarette to help you quit, you'll have to
