This medicine is available without prescription to help relieve and/or prevent unpleasant withdrawal symptoms and cravings for nicotine when you are trying to give up smoking or for when you can’t or don’t want to smoke cigarettes. However, you need to use it carefully to get the best results from it.

• Keep this leaflet, you may need to read it again
• Ask your pharmacist if you need more information or advice

For the best effect, ensure that you use Boots NicAssist Ice Mint Gum correctly – see “How to use the gum”.

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 smoking related disease and death, not the nicotine.

• You may think that smoking helps relieve feelings of anxiety and stress, but it does not deal with the cause of the stress and leads to a number of serious diseases. In addition, the feeling of relaxation after smoking is temporary, with withdrawal symptoms and cravings soon returning
  Nicotine replacement therapy can help relieve nicotine withdrawal symptoms such as irritability, low mood, anxiety, restlessness and cravings when used in place of cigarettes.
• NRT may benefit smokers who want to quit, by helping to control weight gain that may be experienced when trying to stop smoking
  Use of NRT is safer than smoking tobacco but as soon as you are ready, you should aim to stop smoking completely.

• If you are allergic to any of the ingredients in this medicine (see “What is in this medicine”)
• If you are a child under 12 years of age

• If you are in hospital because of heart disease (e.g. heart attack, problems with your heart rate or rhythm, stroke, angina or high blood pressure) – try to give up smoking first without using NRT. However, once you are out of hospital, if you still need help to stop smoking, you can use this medicine. For other heart conditions that do not require you to be in hospital, using NRT is better than continuing to smoke
• 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 have an ulcer in your stomach or upper intestine or problems such as pain or swelling of the stomach or oesophagus (the passage between your mouth and stomach)
• If your liver or kidneys do not work properly
• If you have an overactive thyroid gland
• If you have high blood pressure due to a tumour near your kidney (your doctor may have told you that you have a condition called phaeochromocytoma)
• If you are taking other medicines regularly prescribed by your doctor (see “If you take other medicines”)
• If you have ever experienced seizures (fits)
• If you are pregnant or breastfeeding (see “Other important information”)

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, nurse or doctor for more advice.

NRT products that are used intermittently, such as this one, may be preferable to nicotine patches. However, if you feel sick or are sick (morning sickness) the patches may be better for you. If you do use nicotine patches they should be taken off before bedtime.

If you are breastfeeding: You should try to stop smoking without using NRT.

However, if you still need help to stop smoking, it is recommended that you use NRT products that are used intermittently, not patches. You should talk to your pharmacist, nurse or doctor for more advice.

Breastfeeding your baby just before you use the gum makes 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 gum 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 family 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 gum where children may get hold of it.

Some of the ingredients can cause problems: The chewing gum base contains butylated hydroxytoluene (E321), an anti-oxidant. May cause local skin reactions (e.g. contact dermatitis) or irritation to the eyes and mucous membranes.

Information about some of the ingredients in this medicine: This medicine contains less than 1 mmol sodium (23 mg) in each chewing gum, that is to say essentially ‘sodium – free’.

Before you use this medicine, make sure that you tell your pharmacist about ANY other medicines you might be using at the same time, particularly the following:

• Theophylline, clozapine, ropinirole – your doctor may want to monitor the amount of medicine that you take

When you stop smoking or reduce the number of cigarettes you smoke, 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 or reduce the number of cigarettes you smoke and follow his or her advice about these other medicines.

Read all of the following information carefully before using the gum:

• Follow the instructions in the table, which shows when you should use the gum and the maximum amount of gums you should be using each day
• See the “How to use the gum” instructions to make sure that you chew the gum correctly to ensure that nicotine is released and passes into your body through the lining of your mouth
  The strength and number of gums you use each day will depend on how many cigarettes you smoke and how strong they are.
• The 2 mg gum should be used for those who smoke 20 cigarettes or fewer a day
• The 4 mg gum should be used for those who smoke more than 20 cigarettes a day
  However, the 2 mg gum will also be useful for heavier smokers as they gradually start to reduce the strength and number of gums they use each day.
• Boots NicAssist Ice Mint Gum should be used whenever the urge to smoke is felt or when you would normally expect to have cravings to smoke
• It is recommended that to successfully reduce the amount of cigarettes you smoke or stop smoking completely you should use the gums as often as possible and it is up to you how many gums you use (up to 15 a day) and for how long
• If you are ready to stop smoking completely, you should use the gums, when needed, to replace all of your cigarettes. As soon as you feel ready (this could be after a number of weeks or months) you should reduce the strength, if required, and number of gums used per day until you no longer need to use the gums
• If you are not ready to stop smoking completely, you should replace as many cigarettes as possible with the gums. Boots NicAssist Ice Mint Gum provides a safer alternative to smoking for you and those around you, as it is the toxins in cigarette smoke that cause harm, not the nicotine. Reducing the amount of cigarettes you smoke may also help you to become more motivated to stop smoking. As soon as you feel ready, you should aim to stop smoking completely
• You can also use the gums when you can’t or don’t want to smoke, such as social occasions e.g. at a party, in the pub, or for when you are at work, or on a plane or train etc.

When making an attempt to stop smoking completely behavioural therapy, advice and support will normally improve the success rate.

If you smoke 20 cigarettes or fewer per day: Use one 2mg gum as required to relieve and/or prevent cravings

If you smoke more than 20 cigarettes per day: Use one 4mg gum as required to relieve and/or prevent cravings

Use only one piece of gum at a time.

Don’t use more than 15 gums per day.

You should always aim to stop smoking completely whilst using the gums.

If you are unable to reduce the strength or number of gums you are using you should ask for help and advice from a pharmacist, nurse or doctor.

Do not give this medicine to children under 12 years of age.

The method of chewing Boots NicAssist Ice Mint Gum is not the same as for ordinary chewing gum. If the gum is chewed all the time (continuously), the nicotine is released too quickly and is swallowed. This may irritate your throat, upset your stomach or give you hiccups.

The gum should be chewed and then rested to release the nicotine, which is taken in through the lining of the mouth.

If you have false teeth you may have difficulty chewing the gum as it may stick to them, and on rare occasions, damage dentures. If you experience a problem, other types of nicotine replacement therapy such as a skin patch, inhalator, lozenge or microtab may be more suitable for you.

1 Chew slowly until taste becomes strong
2 Rest the gum between your gums and cheek
3 For about the next half an hour, when the taste fades, chew the gum again. After this time the gum will have lost its strength and you should dispose of it carefully

If you use too many gums: You may get the following – nausea (feeling sick), vomiting, increased salivation, pain in your stomach, diarrhoea, sweating, headache, dizziness, hearing disturbance, weakness. If this happens stop using the gums and do not smoke. Contact a doctor or hospital casualty department straight away. Take the medicine and this leaflet with you.

If a child under 12 accidentally uses, swallows, sucks or chews some of this medicine take them to casualty immediately. Take the medicine and this leaflet with you. Nicotine ingestion by a child may cause severe poisoning.

• You develop a fast, slow or irregular heart beat
• You have an allergic reaction to the gum such as rash, itching or swelling of the tongue, mouth or throat (go straight to casualty if severe)
• You experience seizures (fits)
