Your NRT guide: choose the right strength and use it well

Patches, gum, lozenges, sprays and inhalators explained in plain English, with the strength that usually suits your smoking habit. Written by a GPhC-registered pharmacy.

Age-restricted: 18+ only. Read the leaflet and speak to a pharmacist or GP before you start.

Which nicotine patch strength?

Patches release nicotine slowly through the skin, so they give a steady background level all day. 16-hour patches come off at bedtime. 24-hour patches stay on day and night.

Find your patch strength
Cigarettes per dayUsual patch strength
20 or more25mg (16-hour) or 21mg (24-hour)
10 to 1915mg (16-hour) or 14mg (24-hour)
Fewer than 1010mg (16-hour) or 7mg (24-hour)

Tip: most people start on a higher strength and step down over a 12-week quit plan.

Which nicotine gum strength?

Gum works fast, so it suits sudden cravings. The strength depends on how soon after waking you usually smoke.

Find your gum strength
Your first cigaretteUsual gum strength
Within 30 minutes of waking4mg gum
More than 30 minutes after waking2mg gum

Tip: use the “chew and park” method. Chew slowly until you notice a tingle or peppery taste, rest the gum between your cheek and gum, then repeat for about 30 minutes.

Lozenges, microtabs and inhalators

Lozenges

Available in 2mg and 4mg. Let them dissolve slowly in your mouth. Do not chew or swallow them.

Mini lozenges and microtabs

Small and discreet. They dissolve in the mouth or under the tongue, so they are easy to use anywhere.

Inhalators

An inhalator mimics the hand-to-mouth action of smoking. One cartridge lasts around 15 to 20 minutes of use.

Mouth and nasal sprays

Sprays give the fastest craving relief of any NRT format.

Mouth spray

1mg per spray. Use 1 to 2 sprays when you need them, up to a maximum of 64 sprays a day.

Nasal spray

0.5mg per spray and faster-acting, so it is often chosen by people who are highly dependent on nicotine. It can feel strong at first, which is normal.

Sugar-free options and diabetes

Sugar-free lozenges are worth discussing with your pharmacist. They include Nicotinell Mint Lozenges (1mg and 2mg), Nicorette Cools 2mg, Nicorette Fruit 2mg, NiQuitin Mint 2mg and NiQuitin Minis Mint 2mg.

If you have diabetes: check your blood glucose more often when you stop smoking or start NRT, as your levels and medicine needs may change. Speak to your pharmacist or diabetes care team before you start.

Our pharmacy team can help you choose a product and strength that fits your smoking habits and your health.

Using more than one product

Combination therapy, such as a patch for steady cover plus gum, a lozenge or a spray for sudden cravings, is often more effective than one product alone. If you get strong withdrawal symptoms or side effects, the strength or mix can be adjusted. Speak to a pharmacist before you change anything.

Your 12 weeks

The NHS recommends using NRT for at least 12 weeks, or longer if you still need support. It helps to check in on your progress at weeks 2, 4, 8 and 12.

For free local support you can also self-refer to the NHS Stop Smoking Service.

Questions and answers

Most people match the patch to how much they smoke: 25mg (16-hour) or 21mg (24-hour) for 20 or more cigarettes a day, 15mg or 14mg for 10 to 19 a day, and 10mg or 7mg for fewer than 10. A pharmacist can confirm the right starting point for you.
