There are two types of medically approved aids to quitting in Australia:
Nicotine Replacement Therapy
Zyban - a non-nicotine medication
Nicotine replacement therapy
Nicotine replacement therapy (NRT) is the collective name for a range of products containing small amounts of nicotine that are designed to help people stop smoking. These include nicotine gum, patches, inhaler and lozenges. These help smokers quit by replacing some of the nicotine they normally get from their cigarettes with nicotine absorbed through the skin and the lining of the mouth. This eases some of the nicotine withdrawal symptoms such as cravings and irritability. Using NRT doubles the chance of successfully quitting compared to using willpower alone.
Research suggests that those who are most likely to benefit from the use of NRT in any of its forms will
currently smoke 15 or more cigarettes a day
be receiving some other form of support (eg Quitline).
When using NRT, you should not smoke at all.
Zyban
Bupropion Hydrochloride (Zyban) is a non-nicotine medication recognised as a smoking cessation aid. It is only available with a doctor’s prescription. It acts on the parts of the brain that are affected by nicotine. It seems to reduce craving and withdrawal symptoms such as frustration and anxiety, difficulty concentrating, restlessness and negative mood.
Some people should not take it, including people who
have ever had seizures
have had head injuries
take some anti-depressants (MAO inhibitors)
take other medication containing bupropion
have, or have had, eating disorders.
It is very important to discuss thoroughly and completely with your doctor, your suitability to use Zyban.
Champix
Champix (also known as Varenicline) is a non-nicotine drug to aid with smoking cessation. It comes in tablet form and works by stimulating receptors for nicotine in the brain. This produces an effect that relieves the craving and withdrawal symptoms you can get when you stop smoking. At the same time, Champix prevents any nicotine inhaled in tobacco smoke from having a rewarding and enjoyable effect.
Some people should not take Champix if:
They are allergic to any of the ingredients that Champix contains;
Are under 18 years of age; or
Are pregnant, planning a pregnancy or breastfeeding.
Before being prescribed Champix by a doctor, it is important to disclose:
allergies to any other medicines, foods, etc;
a history of kidney problems, haemodialysis treatment or repeated fits or convulsions; or
a history of mental illness.
For more information on medications that have been tested and have been shown to reduce withdrawal symptoms, and improve the likelihood of successful quitting, see our information sheet:
No medication will work effectively unless you are committed to quitting. That means that you are prepared to work at dealing with all aspects of your smoking, not just the addiction.
If you also get some help from your doctor, or other health professional, or call the Quitline 13 7848, your chances of success are even better.
