How to take it

the gum

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 skin patches, inhalator, lozenges or microtabs may be more suitable for you.

Chewing technique

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/vape. 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.

number of gums they use each day.

• Boots NicAssist Ice Mint Gum should be used whenever the urge to smoke/vape is felt or when you would normally expect to have cravings to smoke/vape
• It is recommended that to successfully reduce the amount of cigarettes/e-cigarettes you smoke/vape or stop smoking/vaping 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/vaping completely, you should use the gums, when needed, to replace all of your cigarettes/e-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/vaping completely, you should replace as many cigarettes/e-cigarettes as possible with the gums. Boots NicAssist Ice Mint Gum provides a safer alternative to smoking tobacco for you and those around you, as it is the toxins in cigarette smoke that cause harm, not the nicotine. The effects of vaping on your body are not established.
• Reducing the amount of cigarettes/e-cigarettes you smoke/vape may also help you to become more motivated to stop smoking/vaping. As soon as you feel ready, you should aim to stop smoking/vaping completely
• You can also use the gums when you can't or don't want to smoke/vape, 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/vaping completely behavioural therapy, advice and support will normally improve the success rate.
