What is Champix?

Champix is a prescription only medication which is given to help people stop smoking. It's a 12 week treatment which decreases cravings and prevents cigarettes from having a satisfying effect. 

How does Champix work?

Champix both dulls the effect of nicotine and stimulates the receptors in the brain which release dopamine when coming into contact with nicotine. It mimics the way nicotine works in the body to stop you craving it. In addition, it prevents nicotine from being received by the brain so that you don't experience enjoyment from smoking a cigarette. 

How long does Champix take to work?

Champix will usually start to have an effect when you reach the end of your starter pack, around two weeks into the treatment. By this point you will have stopped smoking and your body is adjusting to the change. 

How effective is Champix?

You are twice as likely to successfully quit smoking with Champix in comparison to willpower alone. It's most effective when combined with additional support from counselling or peer groups. 

How safe is Champix?

Champix is safe to use for most people and your doctor will assess your medical history to ensure it is suitable for you before prescribing it. It may not be suitable for people with depression or past mental illness or those with kidney failure or epilepsy. 

How to stop smoking

There are many options to help you stop smoking. Champix is the most effective medication as it has been designed specifically for this purpose and you can take it in combination with behavioural therapy, support groups and resources and support from friends and family. Nicotine replacement therapy is another option and you can get help from the NHS through their Stop Smoking programme. 

How many people are able to quit smoking with Champix?

According to studies, more than double the number of people managed to quit smoking for good in comparison to those taking the placebo drug. This translates to a 22% success rate. While it may sound small, the drug cannot replace the willpower and motivation needed to quit. Combined with behavioural therapy and group support, there is no reason why Champix won't work for you. 

Does Champix work better for certain people?

Champix may be successful for some people while others may find they still want to smoke. While Champix is an effective medication, it cannot replace willpower alone. It works best when you are set on your path to quit smoking and combine the treatment with peer support, one to one therapy and following a set plan. 

Champix and diet

Smoking commonly decreases your appetite and can cause your metabolism to work slightly faster. When you stop, you may find that your appetite increases and you crave sugary or fatty foods in place of cigarettes. Keeping up a healthy diet during this time is important to maintain good nutrition and prevent weight gain. 


Active ingredients

The active ingredient in Champix is varenicline tartrate.

Inactive ingredients

The inactive ingredients in Champix are: microcrystalline cellulose, anhydrous dibasic calcium phosphate, croscarmellose sodium, colloidal silicon dioxide and magnesium stearate. 


Champix Dosage

Champix Standard dose provides 1mg tablets which are taken twice a day. 

How to take Champix

When you finish the Champix starter pack you'll progress to Champix standard dose for the remainder of your treatment. You should take one 1mg tablet twice daily. It should be taken after eating a meal and with a full glass of water. 

Stopping Champix

Champix should be taken for a 12 week period for it to work effectively. If you experience unpleasant side effects from the Champix standard dose then you can switch to the low dose instead. Stopping Champix early means you are less likely to successfully stop smoking. 

How long will I need to take Champix for?

You will need to take Champix for a minimum of 12 weeks for it to be effective. Some people find they need to take it for an extra couple of weeks while others may manage to quit smoking before the 12 weeks.
