What it is and what it is used for

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 to 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.

To improve your chances of successfully giving up smoking you should stop smoking completely when you start to use the lozenges and when you are using the lozenges. Use the "How to suck the lozenge" instructions to make sure that you suck the lozenge correctly to release the nicotine. Suck the lozenge. Do not chew or swallow it. The lozenges are available in two strengths. Use the information and table below to decide which strength of lozenge to use. The 2 mg lozenges should be used by smokers smoking more than 30 cigarettes a day. You should also use the 2 mg lozenges if you have previously failed to give up smoking using the 1 mg lozenges or if you are worried your cravings for nicotine may make you smoke again.

If you use the 2 mg lozenge and find that you get side effects, try using the 1 mg lozenge instead. How to suck the lozenge 1. Suck one lozenge until the taste becomes strong. 2. Rest the lozenge between your gums and cheek. 3. Suck again when the taste has faded. 4. Repeat this routine until the lozenge dissolves completely (about 30 minutes). How many to use: Adults over 18 years: Suck one lozenge every one to two hours when you feel the urge to smoke. Most people use between 8 to 12 lozenges per day. However, if you still have an urge to smoke you can use more lozenges. Do not use more than 15 of the 2 mg lozenges per day. Do not use more than 1 lozenge per hour. Normally you should use the lozenges for at least 3 months, but this may vary from person to person. After 3 months, you should gradually reduce the number of lozenges used each day. When you are using only one or two lozenges per day you should stop completely. In general, you should not use the Boots NicAssist 2 mg Lozenges for more than 6 months. However, some people may need to use them for longer to stop them smoking again. If you need to use the lozenges for longer than 9 months, ask your pharmacist or doctor for advice. Counselling may improve your chances of giving up smoking.

Use in children and adolescents (aged 12-17 years): Do not use the lozenges, unless your doctor tells you to. Use in children below 12 years of age: Not recommended for use in children under 12 years. If you use more lozenges than you should: Sucking too many lozenges can result in the same symptoms as smoking too much. The general symptoms of too much nicotine include weakness, excess sweating, pale skin, increased production of saliva, throat burn, feeling sick, being sick, diarrhoea, pain in the abdomen, disturbance of hearing and vision, confusion, tremor, headache, fast, slow or irregular heartbeat, shortness of breath and circulatory problems.

If a child uses or swallows any lozenges: Talk to a doctor straight away. Take the child to the nearest casualty department. Take the medicines and this leaflet with you.
