Choosing nicotine replacement therapy

We've got a wide range of nicotine replacement therapies which can help you to cut down or stop smoking

What is NRT?

The nicotine found in cigarettes is what makes smoking addictive and causes withdrawal symptoms, like cravings, headaches and irritability when you stop or reduce smoking. Nicotine replacement therapy (NRT) can help fight these symptoms by releasing low levels of nicotine into your body, without the carbon monoxide, tar and other chemicals found in cigarettes. NRT can be used for people who want to stop straightaway or those who want to gradually cut down smoking before stopping. Evidence suggests you can double, and sometimes even triple, your chances of stopping smoking by using NRT. 

The different types of NRT

Nicotine replacement therapy comes in a number of different forms. Which treatment you choose can depend on things like whether you're a heavy or lighter smoker, as well as if you want to cut down on your smoking or stop completely. Your Doctor or pharmacist can help you decide which form of NRT to try if you're unsure.

Nicotine gum

Unlike normal gum, NRT gum is not chewed continuously. It needs to be chewed until the flavour becomes strong, then rested between the cheek and gum so the nicotine passes into your body through your mouth's lining. NRT gum comes in two different strengths, 2mg and 4mg.


Patches release nicotine into your blood stream through the skin. Some are designed to be worn for 24 hours, while others are for 16 hours. To help your patch stick to your skin, apply to a dry, hair-free area and avoid using creams beforehand. Their strengths range from 7mg to 25mg.


If you prefer not to chew gum, you might want to use lozenges instead. Like gum, these need to be rested between the gum and cheek so the nicotine can enter the body through the mouth's lining. If you want a more discreet option than a lozenge, you could consider microtabs which dissolve when placed under the tongue.

Inhalators & sprays

If you miss the hand-to-mouth action of smoking, you might want to use inhalators, which are plastic cigarette-shaped devices. As they release nicotine faster than gum or patches, you might want to use these when you get a craving. If you need rapid and effective relief from cravings, you might want to use a nasal or mouth spray.
