Champix 0.5mg and 1mg

Buy Champix to Stop Smoking

Champix (varenicline) acts on the same receptors in the brain as nicotine. It works by stimulating these nicotinic receptors and produces an effect that relieves the craving and withdrawal symptoms you can get when you stop smoking. Varenicline also blocks nicotine from acting on these nicotinic receptors. This prevents any nicotine inhaled in tobacco smoke from having a rewarding and enjoyable effect. Champix (varenicline) is not the same as nicotine replacement therapy.

All our products are genuine UK medicines and are dispensed by our partner pharmacy based in the UK.

There have been reports of suicidal thoughts or behaviour in people taking this medicine to help them give up smoking. It is very difficult to know if this is due to the medicine, as giving up smoking itself can make people depressed, especially if they already have a mental health condition. However, not all people experiencing depression and suicidal thoughts while taking this medicine had a previous history of psychiatric illness. If you begin to feel agitated or depressed, or experience any changes in your behaviour or thoughts about suicide you should stop taking this medicine and consult your doctor immediately.

Please Note

All medication can cause side effects. We have only listed a few to be aware of. Details of all side effects, including rare side effects to be aware of, are listed in the patient information leaflet (PIL). When completing your medical questionnaire, it is very important that you answer the questions truthfully. This is to ensure your doctor has a full picture of your medical history before prescribing. List all medicines you are already taking, including non-prescription and herbal medicines.


Nicotine replacement therapy is an alternative treatment to help you stop smoking. This is available as inhalers, gums, lozenges, sprays, micro tabs and patches. There is also another prescription medicine called bupropion (trade name Zyban), but this is not available through Anytime Doctor.

The use of this oral medicine follows a set pre-determined route. You should set a date on which you will stop smoking and start taking this medicine one to two weeks beforehand. This is because the medicine needs time to start working.

The dose is increased gradually in the first week of treatment (follow the instructions given by your doctor) and should then be taken twice a day for 12 weeks. If you have successfully managed to stop smoking at the end of 12 weeks, your doctor may offer you a further 12 week course of treatment. The tablets should be swallowed whole with a drink of water. They can be taken with or without food. Please always take your medicine as directed by your doctor, or follow the detailed instructions in the patient information leaflet.
