Champix is an effective smoking cessation medication containing varenicline that has been proven to help reduce cravings, significantly increasing the chance of quitting smoking. It has the highest success rate when compared to other smoking cessation products, including nicotine gum and nicotine patches.

Unlike other smoking cessation products, Champix does not contain a single trace of nicotine. Varenicline acts directly on the nicotine receptors, which reduces the withdrawal symptoms that can hamper would-be quitters. You can buy Champix pills safely online here at OnlineClinic. It will then be dispatched for next day delivery after approval from one of our doctors.

How to buy Champix online?

At OnlineClinic, Champix (varenicline) is only available to buy in 0.5mg and 1mg tablet packs, to be taken as part of a 12-week treatment. Most will find one 12-week course is a success, especially when teamed with supporting factors such as strong will and family support. However, some may order an additional 12-week refill to be sure of preventing any form of relapse.

To buy this stop smoking medication in the UK, you must complete a quick online consultation during your order. Once approved, your medication will be sent to you via our next day delivery service. Medication is always discreetly packaged, allowing you to get treatment delivered anywhere with confidentially and peace of mind the next day.

What is Champix?

Champix is a prescription smoking cessation medication available to buy safely online, containing the active ingredient varenicline tartrate. Taking the form of a formalised 12-week treatment, Champix effectively reduces your craving for nicotine in a controlled and sustained manner. It has the highest success rate of any smoking cessation treatment currently available.

Studies have shown you are up to four times more likely to quit after a course of treatment with Champix tablets than with traditional nicotine replacement therapies (such as nicotine patches or nicotine gum) and twice as likely to quit if you use Champix over Zyban; the only other existing medication that can help you to quit smoking.

What makes Champix so effective is that it's a dual action approach; it dismisses cravings for cigarettes whilst reducing any pleasure derived from smoking.

Short facts about Champix
How to take

Champix treatment takes place over 12 weeks, and consists of taking 0.5 mg and 1mg tablets. Set a quitting date and continue the treatment course even if you slip up.

How it works

The active ingredient, varenicline, binds with the nicotine receptors in the brain, thus reducing both nicotine craving and pleasure derived from nicotine.


Champix has been clinically shown to significantly improve the chances of smokers successfully ceasing their smoking habit over a period of 12 weeks.


VChampix tablets are available to buy at OnlineClinic in the following dosages:

  • Day 1-3: One 0.5 mg tablet daily
  • Day 4-7: Two 0.5 mg tablets daily
  • Week 2-11: Two 1mg tablets daily (preferably morning and evening)

Side effects

The most common side effects of Champix include nausea, insomnia, abnormal dreams, headaches, and nasopharyngitis (inflammation of the nose and throat).

How does Champix work?

Champix tablets contain the active ingredient varenicline tartrate. Varenicline is a nicotine receptor 'antagonist', meaning it attaches itself to the receptors in your brain that normally respond to nicotine. This means your brain is fooled into thinking you have received your usual dose of nicotine, helping you in two different ways. Firstly, this alleviates any craving for the nicotine contained in cigarettes. Secondly, it reduces the pleasure attained through smoking cigarettes.

To ensure the treatment is as effective as possible, Champix also increases the amount of dopamine produced in the brain. Dopamine is a 'feel good' chemical produced by desired things such as nicotine.

In short, when you do smoke, you will not experience of any of the usual benefits you associate with the habit.

How to take Champix?

Champix is simple and easy to use over a 12-week treatment period:

  • Set a date on which to stop smoking, and begin taking your Champix tablets one to two weeks before the set date. This gives the medicine a chance to start working.
  • The intake of Champix is gradually increased in a controlled manner (to avoid unnecessary side effects) over the course of the first week:
    • One 0.5 mg tablet once a day for three days, followed by two 0.5 mg tablets a day for four days, and then finally increased to two 1mg tablets a day for the remaining 11 weeks.
  • This medicine should be taken with water, with or without a meal.


Champix is available to buy at OnlineClinic in a dose of 0.5mg or 1mg. These dosages are issued together and can be purchased in the form of a starter pack, lasting for two weeks, or as a refill pack, ranging from two to eight weeks.

To prevent you from experiencing any adverse side effects from taking Champix tablets, the dosage is steadily increased over the first week from one 0.5 mg tablet a day to two 1 mg tablets a day for the proceeding 11 weeks.

Side effects and precautions

Champix has been known to cause some side effects for a small number of users. In most cases, however, any side effects are vastly offset by the improvements in health associated with quitting smoking. The most common side effect is mild, transient nausea. Other side effects may include:

  • headaches, insomnia, abnormal dreams, sleepiness, dizziness, changes in taste, dry mouth, constipation, diarrhoea, indigestion, flatulence, restlessness and skin irritation.

Champix is a well tolerated treatment, producing few side effects in few users. However, there are certain precautions that should be observed before you buy Champix online:

  • Champix should be used with caution by those suffering from decreased kidney or heart function.
  • This medication should be avoided by those with a history of psychiatric illness, such as schizophrenia and bipolar disorder.
  • Champix has not been studied in people with epilepsy, and should therefore be avoided by those who suffer from this condition.
  • There is some evidence to suggest Champix may cause mood changes and depression in certain people. For this reason, make sure you inform family and close friends (or your NHS doctor) that you are taking Champix, so that they can observe any potential changes in behaviour.
