What is it?

Champix (varenicline) is Pfizer's new prescription tablet designed to help smokers stop smoking. Champix is a non-nicotine tablet that helps you quit smoking. With assistance of behaviour adaptation and counseling it helps you get rid of your smoking habit completely and quickly. Champix is reported to have the potential to be a significant therapeutic advance over existing therapies.

Are Champix and Chantix the same?

Except for the name, both medicines have same active ingredient (varenicline), same effects and are manufactured by same company, Pfizer. However chantix is available only in the US while Champix is presently approved for sale only in the European Union.

How does it work?

Champix tablets contain the active ingredient varenicline, a type of medicine called a nicotinic acetylcholine receptor partial agonist. This means that it acts on the same receptors in the brain as nicotine does.

Varenicline works by stimulating the nicotinic receptors 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, varenicline blocks nicotine from acting on the receptors. This reduces the satisfaction a smoker receives when smoking a cigarette.

How well does it work?

Studies indicate that about 4 in 10 smokers who want to quit smoking will be able to do so with the help of Champix. This is better than those who are able to quite using previously available medicines (bupropion or nicotine replacement therapy such as nicotine gum, spray, etc.)

This figure is based on two large trials that involved several thousand smokers who wanted to quit. In the trials, smokers were randomly assigned to either Champix plus regular counseling ('stop smoking' counseling), or bupropion plus counseling, or dummy tablets plus counseling. In trials, 44% of the group treated with Champix had stopped smoking after being treated for 12 weeks, as opposed to 11% of smokers taking the placebo. Over the same duration, it was also shown to be twice as effective as Zyban (bupropion), the other main anti-smoking drug treatment.

How do I take it?

• Decide on a 'quit date' - the date you intend to stop smoking.
• Start taking the tablets one week before the 'quit date'. The aim is to build up the dose so your body gets used to the medicine before the 'quit date'. The usual advice is to start with 0.5mg daily for the first three days. Then 0.5mg twice daily on day´s four to seven. Then, 1mg twice daily for 12 weeks.
• Take each dose with a full glass of water, preferably after eating. So, ideally, after breakfast, and after your evening meal.
• Tell your doctor if you develop any side-effects. A reduction in dose may be an option.

The usual course of treatment is for 12 weeks. If you have successfully stopped smoking by this time:

• In many cases, treatment is stopped and that is it. You are a non-smoker!
• In some cases, an additional 12 weeks of treatment may be advised. You can discuss this with your doctor. It may be useful for people who are not confident off the cigarettes.
• In some cases, a short 'tapering off' of the dose over a week or so may be helpful. This is because at the end of treatment, if the medicine is stopped abruptly, some people develop an increase in irritability, an urge to smoke, depression, and/or sleeping difficulty for a short time. These problems can be eased by a gradual reduction of dose.
• If you have not succeeded in quitting after 12 weeks there is no point in continuing with treatment at this time. Perhaps it is best to discuss things over with your doctor or practice nurse as to your future options.
