Congratulations on taking the first step to becoming smoke-free!

It’s not an easy decision to make and giving up smoking can be challenging, but you will soon feel the benefits of not smoking. The first few weeks are often the hardest as this is the time when cravings and withdrawal symptoms are at their worst. But these effects do lessen with time and it will get easier the longer you stay smoke-free. You have been prescribed CHAMPIX to help support you in your quit attempt.

Harmful effects of smoking

Smoking is a major preventable cause of death worldwide, and giving up smoking significantly reduces the risk of dying from tobacco-related diseases such as heart disease and lung cancer.

What is CHAMPIX?

CHAMPIX is a prescription medicine, called varenicline, which is used to help adults to quit smoking. Unlike nicotine replacement therapies (e.g. nicotine patches, gum or inhalation devices), CHAMPIX does not contain any nicotine. It blocks the action of nicotine in your brain and helps to reduce cravings and withdrawal symptoms associated with giving up smoking.

What to expect with CHAMPIX treatment?

When do I start taking CHAMPIX?

You should start taking your CHAMPIX tablets 1−2 weeks before you quit smoking. Before you start taking your CHAMPIX you should set your quit date. This should be in the second week of treatment (between day 8 and day 14). It’s important to write this date on the pack as a reminder. If you are unable (or unwilling) to give up on your designated quit date, you can choose an alternative quit date within 5 weeks of starting treatment. Again, you should make a note of this date on the pack as a reminder. Alternatively, you can choose to reduce smoking during the first 12 weeks of treatment and quit by the end of that treatment period. You should then continue to take CHAMPIX 1 mg film-coated tablets twice daily for a further 12 weeks, resulting in a total of 24 weeks of treatment. You should discuss your treatment schedules with your healthcare professional.

How long do I need to take CHAMPIX for?

It is recommended that you complete a 12-week course of CHAMPIX treatment. This will help you to get the full benefits from your treatment and improve your chances of quitting smoking.

Starting treatment with CHAMPIX

Your first prescription will be for a 4-week or 2-week starter pack. This is because you take a lower dose of CHAMPIX during the first week of treatment. The tablets you need to take each day are clearly labelled on your blister pack

Your CHAMPIX dose

The usual dose of CHAMPIX is 1 mg twice daily following the first week of treatment.


When you have completed your starter pack you will continue treatment at 1 mg twice daily, provided in a 4-week or 2-week continuation pack. However, your doctor may recommend a different dose. For example, if you experience adverse effects that you cannot tolerate, or if you have problems with your kidneys, you should speak to your doctor before taking CHAMPIX as you may need a lower dose.

Possible side effects

Like all medicines CHAMPIX can cause side effects, although not everyone gets them. The most common side effect is nausea. See the leaflet inside your CHAMPIX pack for in-depth details. Giving up smoking with or without treatment can cause various symptoms. These could include changes of mood (like feeling depressed, irritable, frustrated or anxious), sleeplessness, difficulty concentrating, decreased heart rate, increased appetite or weight gain.

Depressed mood, rarely including suicidal thoughts and suicide attempt, may be a symptom of nicotine withdrawal with or without medication. If you are taking CHAMPIX and notice this sort of change in your mood, or unusual agitated behaviour, you should stop your treatment and contact your doctor immediately.

New or worse heart or blood vessel (cardiovascular) problems have been reported in people who already have cardiovascular or stroke problems. Tell your doctor if you have any changes in symptoms during treatment with CHAMPIX. Get emergency medical help right away if you have symptoms of a heart attack.

Some people have reported seizures while taking CHAMPIX. Tell your doctor if you have experienced seizures or have epilepsy before you start CHAMPIX treatment.

If you are concerned about side effects, always speak to your doctor straight away.

Increase your chance of quitting smoking successfully

It has been shown that the longer you stay on treatment, the greater the chance of successfully quitting. Completing the 12-week treatment course can increase your chance of quitting by more than 10 times, compared to people who complete up to 2 weeks of treatment.

Remember to take your tablets every day

It is important that you take CHAMPIX every day as instructed to gain maximum benefit from your treatment.

Taking your tablets at the same time every day e.g. when brushing teeth can help to make your treatment part of your daily routine. If you find it difficult to do this, setting an alarm on your mobile phone can help you to remember.

The CHAMPIX packaging is also clearly labelled to help you remember to take it every day.
