NON-NICOTINE STOP SMOKING MEDICATION

What is Champix® (varenicline)? 

What is Champix® (varenicline)? 

Champix® is the brand name for the non-nicotine stop smoking medication, varenicline tartrate, which can help with feelings of withdrawal such as cravings, irritability and difficulty concentrating. Champix comes in tablets. In clinical trials, Champix has been shown to increase quit rates.

How does Champix work?

When tobacco smoke is inhaled, nicotine travels through your lungs, into your bloodstream and to your brain. Here, it attaches to receptors in the brain and a chemical called dopamine is released, which provides a short-lasting feeling of pleasure. It is believed that Champix also attaches to these receptors, but blocks the nicotine from attaching to them. Champix provides a continual release of dopamine spread out across the day, but it’s not as intense as a cigarette, so smoking becomes less enjoyable. People taking Champix tablets usually get reduced cravings and feelings of withdrawal, such as difficulty concentrating, frustration, restlessness and anxiety.

How well does Champix work?

Champix helps many people to quit smoking, but may not work for everyone. Research has found that Champix can more than double the chance of successfully quitting if combined with  support like Quitline counselling – 13 7848. Quitline counsellors can give you tips and strategies for dealing with triggers and cues to smoke, while the medication helps to manage feelings of nicotine withdrawal and cravings.
