Champix (Varenicline)

What is Champix?

Champix is a relatively new medication from Pfizer which enables people to give up smoking. As Champix is a prescription only medication, we will require you to complete a short online consultation before you can proceed with a purchase.

After you submit the short questionnaire with your medical details, it will be reviewed by one of our doctors who will, if appropriate, approve you for this treatment. Following approval, you will be able to login and purchase the treatment for next day delivery in the UK.

How Does Champix Work?

Varenicline (the active ingredient in Champix) binds to the nicotine receptors in the brain. As a result of this process the nicotine receptors will be satisfied and will not send out craving signals which would lead a smoker to desire a cigarette. If you do end up smoking while on Champix you are unlikely to derive any pleasure from it. This should allow you to break the habit over the 12 week period that you are on the medication. Some people even feel nauseous if they have a cigarette while on Champix.

How Effective is Champix?

Clinical trial results demonstrated that 44% of patients being treated with Champix were able successfully to give up smoking over the 12 week period. This compared very favourably against Zyban, the only other oral smoking cessation treatment, which had a 29.5% success rate over the same period.

What Form Does Champix Come In?

Champix comes in tablet form only. It is necessary to gradually build up the dosage, starting with 0.5 mg once per day up to two lots of 1.0 mg a day over a period of time. The full course is 12 weeks long but it may be possible to extend it for a maximum of a further 12 weeks depending on how well a patient is responding.

Precautions with Champix

Stopping smoking can affect the way that certain other drugs work so you should always discuss stopping smoking with your doctor if you are taking theophylline, warfarin or insulin as a dosage adjustment may be necessary. It may exacerbate underlying psychiatric illness including depression. Caution must also be taken with conditions that lower seizure threshold or a history of cardiovascular disease.

What are the side effects of Champix

As with all medications, Champix can produce unwanted side effects but most people do not experience any side effects at all. A full list of potential side effects is given in the pre-purchase guidance if you are approved for a Champix prescription by one of our doctors. The most common side effects are headaches and nausea.
