Champix Tablets


Champix (Varenicline) is a prescription medication taken orally to help people stop smoking. Research has shown that you are twice as likely to stop smoking with the help of Champix. It works by blocking nicotine receptors in the brain, thereby reducing cravings for cigarettes but also reducing the pleasurable effects from smoking. Users find after taking Champix for one week that they do not get the same enjoyment of smoking, and less cravings.

Starting Treatment

Before starting treatment, you should set a quit date on which you aim to stop smoking. Prior to reaching the quit date, you should dispose of all cigarettes and smoking paraphernalia to minimise the risk of you failing. The quit date can be set to start after you have started taking Champix, but should ideally be no longer than 2 weeks into treatment.

Users begin with the starter pack, which gradually increases the drug dose over the first 2 weeks. This helps the body to get use to the medication and minimise side effects. By the end of the starter pack, users should have stopped smoking. Once the starter pack course has been taken, users can continue with the maintenance pack for an additional 10 weeks.
