What this medicine is for
This medicine contains nicotine which belongs to a group of medicines called nicotine replacement therapy (NRT). It acts to substitute the nicotine that you normally get from cigarettes and can help you stop smoking.
It can be used to relieve the symptoms of nicotine withdrawal and reduce the cravings for nicotine that you get when you try to stop smoking. When you suck the lozenge, nicotine is released slowly and taken into the body through the lining of the mouth.
To help you quit smoking you should also try to use a behavioural support programme or counselling to increase your chances of success.
The benefits of stopping smoking far outweigh any potential risk from using nicotine from NRT. It is the toxins in cigarette smoke such as tar, lead, cyanide and ammonia that cause known smoking related diseases, not the nicotine.
Before you use this medicine
This medicine can be used by adults of 18 years and over. However, some people should not use this medicine or should seek the advice of their pharmacist or doctor first.
Do not use:
- If you are allergic to any of the ingredients in this medicine (see “What is in this medicine”)
- If you are a non-smoker
- If you have phenylketonuria (this medicine contains aspartame (E951), a source of phenylalanine equivalent to 5 mg per lozenge, which may be harmful to you)
- If you have an intolerance to some sugars, unless your doctor tells you to (this medicine contains maltitol, a source of fructose)
Talk to your pharmacist or doctor:
- If you have heart problems including a previous heart attack, heart failure, problems with your heart rate or rhythm, angina, have had a stroke, or high blood pressure not controlled by medication – try to give up smoking first without using NRT. However, if you still need help to stop smoking you can use this medicine but your doctor may want to monitor you more closely
- If you have high blood pressure
- If you have problems with your circulation
- If you have a tumour near your kidney (your doctor may have told you that you have a condition called phaeochromocytoma)

- If your liver or kidneys do not work properly
- If you have an overactive thyroid gland
- If you have diabetes – monitor your blood sugar levels more often when you start using this medicine. You may find that you need to adjust the amount of insulin that you use, or the amount of tablets that you take (ask your doctor or diabetes nurse about this)
- If you are on a low salt (sodium) diet (each lozenge contains 9.8 mg of sodium, which may be harmful to you)

Other important information
Driving and using machines:
Using this medicine is not known to affect your ability to drive or use machines. However you should bear in mind that giving up smoking can change your behaviour.
Using this medicine with food and drink:
Coffee, acidic and soft drinks may decrease the absorption of nicotine. Do not drink them for 15 minutes before sucking a lozenge.
Information about some of the ingredients in this medicine:
Maltitol (E965) may have a mild laxative effect. Each lozenge contains 0.9 g maltitol. This provides 2 kcal per lozenge. This may need to be taken into account if you have diabetes.
If you are pregnant:
You should try to stop smoking without using NRT.
However, if you still need help to stop smoking, you can use this product as the risk to your baby is far less than if you continue to smoke. You should talk to your pharmacist or doctor for more advice.
If you are breast-feeding:
You should try to stop smoking without using NRT.
However, if you still need help to stop smoking, you can use this medicine. You should talk to your pharmacist or doctor for more advice.
Do not use the lozenges in the 2 hours before you feed your baby. Then breastfeed your baby just before you use the lozenge, to make sure that your baby gets the smallest amount of nicotine possible.
The amount of nicotine that your baby may receive when you are using the lozenges or other NRT products is much smaller and less harmful than the second-hand smoke they would inhale if you smoked. Tobacco smoke causes breathing and other health problems in babies and children. If your husband, partner or other household members smoke too, try to get them to give up with you.
Nicotine products and children:
Nicotine can be very dangerous to children. The amount of nicotine tolerated by adults and adolescents can make children very ill, and can sometimes be fatal. Do not leave your lozenges where children may get hold of them.
If you take other medicines
Before you use this medicine, make sure that you tell your doctor or pharmacist about ANY other medicines you might be using at the same time, particularly the following:
- Theophylline (for breathing problems)
- Tacrine (for Alzheimer’s disease)
- Olanzapine or clozapine (used to treat schizophrenia)
- Insulin (for diabetes)
When you stop smoking your metabolism slows down. This can mean that some medicines may stay in your body longer than usual.
If you take any medicine on a regular basis, tell your doctor that you intend to stop smoking and follow his or her advice about these medicines. This includes medicines prescribed by your doctor and medicine you have bought for yourself, including herbal and homeopathic remedies.
