Champix is a non-nicotine treatment. It is a prescription pill designed to help smokers stop smoking. You will need to see your GP before you can be prescribed Champix.
How does Champix work?
Champix works in two key ways. Firstly, it reduces the smoker’s craving for nicotine and the symptoms of withdrawal by binding to nicotine receptors in the brain. Secondly, it reduces the satisfaction a smoker receives when smoking a cigarette.
Is Champix available in Cambridgeshire?
Champix is available in Cambridgeshire to those people who are medically assessed by a GP and deemed a suitable candidate. It is not suitable for clients under the age of 18 or pregnant or nursing women.
