What is it and how is it used?

CHAMPIX is a a non-nicotine medicine which is used to help you stop smoking.

CHAMPIX can help to relieve the craving and withdrawal symptoms associated with stopping smoking.

Although you are not recommended to smoke after your quit date, CHAMPIX can also reduce the enjoyment of cigarettes if you do smoke when on treatment. (The quit date is the day in the second week of treatment when you will stop smoking, see Section 3.)

What do you have to consider before using it?

Do not take CHAMPIX

  • If you are allergic (hypersensitive) to varenicline tartrate or any of the other ingredients of CHAMPIX
Take special care with CHAMPIX

There have been reports of depression, suicidal ideation and behaviour and suicide attempts in patients taking CHAMPIX. If you are taking CHAMPIX and develop agitation, depressed mood, changes in behaviour that are of concern to you, your family or doctor or if you develop suicidal thoughts or behaviours you should stop your treatment and contact your doctor immediately.

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

The effects of stopping smoking

The effects of changes in your body resulting from stopping smoking, with or without treatment with CHAMPIX, may alter the way other drugs work. Therefore, in some cases an adjustment of the dose may be necessary. Examples include theophylline (a medicine to treat breathing problems), warfarin (a medicine to reduce blood clotting), and insulin (a medicine to treat diabetes). If in doubt, you should consult your doctor or pharmacist.

For some people, stopping smoking with or without treatment has been associated with an increased risk of experiencing changes in thinking or behaviour, feelings of depression and anxiety and can be associated with a worsening of psychiatric illness. If you have a history of psychiatric illness you should discuss this with your doctor or pharmacist.

Depressed mood may appear during smoking cessation with or without treatment. Depression, rarely including suicidal thoughts and suicide attempt, has been reported in patients undergoing a smoking cessation attempt. These feelings have also been reported while attempting to quit smoking with CHAMPIX. If these symptoms persist when you stop taking CHAMPIX, your doctor should continue to monitor you closely until you are feeling better.

You may temporarily experience increased irritability, urge to smoke, depression and/or sleep disturbances when you stop taking CHAMPIX. Your doctor may decide to gradually lower your dose of CHAMPIX at the end of treatment.

Effect of CHAMPIX on other drugs

CHAMPIX is not expected to affect the way other drugs work.

Effect of other drugs on CHAMPIX

Due to the way in which varenicline tartrate is removed from the body, it is not expected that other drugs will affect the way in which CHAMPIX works.

Use of CHAMPIX with other therapies for smoking cessation

The safety and benefits of taking CHAMPIX in combination with other medicines for stopping smoking have not been studied. CHAMPIX in combination with other smoking cessation therapies is therefore not recommended.

CHAMPIX is not recommended for use in children or adolescents below 18 years.

Taking CHAMPIX with food and drink

CHAMPIX can be taken with or without food.

Pregnancy

You should not take CHAMPIX while you are pregnant.

Talk to your doctor if you are intending to become pregnant. If you want to start treatment with CHAMPIX, your treatment should be timed so that you have completed the course before becoming pregnant.

Breast-feeding

Although it was not studied, CHAMPIX may pass into breast milk. You should ask your doctor or pharmacist for advice before taking CHAMPIX.

Driving and using machines

CHAMPIX may produce dizziness and sleepiness. You should not drive, operate complex machinery or engage in any other potentially hazardous activities until you know whether this medication affects your ability to perform these activities.

How is it used?

You are more likely to stop smoking if you are motivated to stop. Your doctor and pharmacist can provide advice, support and sources of further information to help ensure your attempt to stop smoking is successful.

Always take CHAMPIX exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

Before starting your course of CHAMPIX you should usually decide on a date in the second week of treatment (between day 8 and day 14) when you will stop smoking. If you are not willing or able to set a target quit date within 2 weeks, you may choose your own target quit date within 5 weeks after starting treatment. You should write this date on the pack as a reminder.

CHAMPIX tablets should be swallowed whole with water.

The usual dose for adults which you should follow from Day 1 is described in the following table:

Week 1 Dose Day 1 - 3 From day 1 to day 3, you should take one white CHAMPIX 0.5 mg film-coated tablet once a day. Day 4 - 7 From day 4 to day 7, you should take one white CHAMPIX 0.5 mg film-coated tablet twice daily, once in the morning and once in the evening, at about the same time each day.

Week 2 Day 8 14 From day 8 to day 14, you should take one light blue CHAMPIX 1 mg film-coated tablet twice daily, once in the morning and once in the evening, at about the same time each day.

Weeks 3 - 12 Day 15 - end of treatment From day 15 until the end of treatment, you should take one light blue CHAMPIX 1 mg film-coated tablet twice daily, once in the morning and once in the evening, at about the same time each day.

Should you experience adverse effects that you cannot tolerate your doctor may decide to reduce your dose temporarily or permanently to 0.5 mg twice daily.

After 12 weeks of treatment, if you have stopped smoking, your doctor may recommend an additional 12 weeks of treatment with CHAMPIX 1 mg film-coated tablets twice daily.

In smoking cessation therapy, risk of returning to smoking may be elevated in the period immediately following the end of treatment. Your doctor may decide to gradually lower your dose of CHAMPIX at the end of treatment.

If you have problems with your kidneys, you should speak to your doctor before taking CHAMPIX. You may need a lower dose.

If you take more CHAMPIX than you should

If you accidentally take more CHAMPIX than your doctor prescribed, you must seek medical advice or go to the nearest hospital casualty department immediately. Take your box of tablets with you.

If you forget to take CHAMPIX

Do not take a double dose to make up for a forgotten tablet. It is important that you take CHAMPIX regularly at the same time each day. If you forget to take a dose, take it as soon as you remember. If it is almost time for your next dose, do not take the tablet that you have missed.

If you stop taking CHAMPIX

It has been shown in clinical trials that taking all doses of your medicine at the appropriate times and for the recommended duration of treatment described above will increase your chances of stopping smoking. Therefore, unless your doctor instructs you to stop treatment, it is important to keep taking CHAMPIX, according to the instructions described in the table above.

If you have any further questions on the use of this product, ask your doctor or pharmacist.
