Patient leaflet - Nicassist 1 mg / spray Mouth spray
1. What Nicotine mouth spray is and what it is used for
Nicotine mouth spray is a nicotine replacement therapy (NRT).
It is used to relieve and /or prevent withdrawal symptoms and reduce the cravings you get when you try to stop smoking or when cutting down the number of cigarettes you smoke.
Ideally you should always aim to stop smoking. You can use Nicotine mouth spray to achieve this by using it to completely replace all your cigarettes.
However, Nicotine mouth spray can also be used in other ways:
- If you feel unable to stop smoking completely, or wish to replace certain cigarettes, it can help you to cut down the number of cigarettes you smoke.
At those times when you can’t or do not want to smoke. For example:
- Where you don’t want to smoke and avoid harm to others e.g. children or family.
- Smoke free areas e.g. Pub, work, public transport e.g. aeroplanes.
It may also help increase your motivation to quit.
When making a quit attempt a behavioural support programme will increase your chances of success.
What does Nicotine mouth spray do?
When you stop smoking your body misses the nicotine that you have been absorbing. You may experience unpleasant feelings and a strong desire to smoke (craving). This indicates that you were dependent on nicotine.
The nicotine in Nicotine mouth spray passes quickly into your body through the lining of your mouth.
This relieves the craving for nicotine and the unpleasant withdrawal symptoms when you stop smoking, but does not give you the “buzz” you get from smoking a cigarette.
Benefits you can get from using NRT instead of smoking
For the best effect, ensure that you use Nicotine mouth spray correctly – see “How to Use Nicotine mouth spray.”
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 diseases and death, not the nicotine.
Although you may feel that smoking helps relieve anxiety and stress, 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.
NRT can help relieve nicotine withdrawal symptoms such as irritability, low mood, anxiety, restlessness and cravings when used in place of cigarettes.
Use of NRT is safer than smoking tobacco but as soon as you are ready, you should aim to stop smoking completely.

Warnings and precautions
! Talk to your doctor, nurse or pharmacist before using Nicotine mouth spray
If you are pregnant or breast-feeding
- You may be able to use nicotine replacement therapy (NRT) to help you give up smoking but you should try to give up without it. See the “Pregnancy and breast-feeding” section.
- If you have small children around - doses of nicotine tolerated by adult and adolescent smokers can produce severe poisoning in small children that may be fatal. Products containing nicotine should not be left where they may be misused, handled or ingested by children.
If you are in hospital because of heart disease (including heart attack, chest pain, disorders of heart rate or rhythm, or stroke).
In other heart conditions not requiring you to be in hospital, using NRT is better than continuing to smoke.
- If you have a stomach ulcer, duodenal ulcer, inflammation of the stomach or inflammation of the oesophagus (passage between the mouth and stomach).
- If you have liver or kidney disease.
- If you have an overactive thyroid gland or have a phaeochromocytoma (a tumour of the adrenal gland that can affect blood pressure) – your doctor will have told you this.
- If you have diabetes – monitor your blood sugar levels more often when starting to use Nicotine mouth spray as you may find your insulin or medication requirements alter.
- If you tend to suffer from allergic reactions - especially a raised red and itchy rash (urticaria / hives), and/or swelling (puffiness) that can affect the eyes, lips, throat, hands, feet, genitals or other areas of the body (angio-oedema).
- If you have seizures (fits) - patients taking medicines called anticonvulsants, or who have a history of epilepsy, need to take extra caution, as nicotine has been known to cause seizures.
- If you are taking any other medicines such as theophylline, tacrine, clozapine or ropinirole. Stopping smoking may require the dose of these medicines to be adjusted.
If any of these apply, talk to your doctor, nurse or pharmacist.
Other medicines and Nicotine mouth spray
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This is especially important if you use other medicines which contain theophylline, tacrine, clozapine, ropinirole, or insulin.
Pregnancy, breast-feeding and fertility
If you are pregnant:
It is very important to stop smoking during pregnancy because it can result in poor growth of your baby. It can also lead to premature births and even stillbirths.
- 1) You should try to give up smoking without NRT. Stopping completely is by far the best option. The earlier and quicker you do this the better it is for you and your baby.
- 2) If you can’t manage this, you can use NRT as a safer alternative to smoking as the risks to your baby are far less than smoking, however you should talk to your doctor, nurse or pharmacist for advice.
Products that are used intermittently, including Nicotine mouth spray may be preferable to nicotine patches. However, patches may be more suitable if you have nausea or sickness. If you do use patches take them off before going to bed at night.
If you are breast-feeding:
- 1) You should try to give up smoking without NRT.
- 2) If you can’t manage this it is best to use NRT products such as Nicotine mouth spray that are taken intermittently (not patches), however you should talk to your doctor, nurse or pharmacist for advice. Breast-feed just before you use Nicotine mouth spray to ensure that the baby gets the smallest amount of nicotine possible.
If you do need to use NRT to help you quit, the amount of nicotine that the baby may receive is considerably smaller and less harmful than the second-hand smoke they would inhale if you smoked. Tobacco smoke produces breathing and other problems in babies and children. If your husband, partner or other family members smoke too, try to get them to give up with you.
Smoking increases the risk of infertility in women and men. The effects of therapeutic nicotine treatment on fertility is unknown.
Driving and using machines
There are no known risks associated with driving or using machinery when the Nicotine mouth spray is used according to the recommended dose.
Nicotine mouth spray contains ethanol (alcohol)
Nicotine mouth spray contains small amounts of ethanol (alcohol), the amount is less than 100 mg per spray.
