2. What you need to know before you take CHAMPIX

Do not take CHAMPIX

• If you are allergic to varenicline or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Tell your doctor or pharmacist before you start taking CHAMPIX.

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

Effects of stopping smoking

The effects of the changes in your body as a result of stopping smoking, with or without treatment with CHAMPIX, may alter the action of other medicines. Therefore, in some cases, it may be necessary to adjust the dose of other medicines. See below for more details in “Other medicines and CHAMPIX”.

Stopping smoking, with or without treatment, has been associated in some people with an increased risk of experiencing changes in thinking or behaviour, feeling depressed or anxious, and may be associated with worsening of a psychiatric disorder. If you have a history of psychiatric disorder, you should discuss this with your doctor.

Cardiac symptoms

There have been reports of worsening or new cases of heart or blood vessel problems (cardiovascular) mainly in people who already had cardiovascular problems. Tell your doctor if you experience any change in symptoms during treatment with CHAMPIX. If you experience symptoms of a heart attack or stroke, seek immediate medical help.

Seizures

Before starting treatment with CHAMPIX, tell your doctor if you have had seizures or if you are epileptic. Some people have observed seizures during treatment with CHAMPIX.

Hypersensitivity reactions

Stop taking CHAMPIX and tell your doctor immediately if you experience any of the following signs and symptoms that may indicate a severe allergic reaction: swelling of the face, lips, tongue, gums, throat, or body, or difficulty breathing, wheezing.

Skin reactions

There have been reports of potentially life-threatening skin reactions (Stevens-Johnson syndrome and erythema multiforme) with the use of CHAMPIX. If you develop a rash or blisters or your skin peels or sheds, you should stop taking CHAMPIX and seek urgent medical attention.

Children and adolescents

CHAMPIX is not recommended for use in patients under 18 years of age, as its efficacy has not been demonstrated in this age group.

Using CHAMPIX with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

In some cases, as a result of stopping smoking, with or without CHAMPIX, it may be necessary to adjust the dose of other medicines. Examples include theophylline (a medicine for respiratory problems), warfarin (a medicine to reduce blood clotting), and insulin (a medicine for diabetes). If you are in doubt, consult your doctor or pharmacist.

If you have severe kidney disease, you should avoid taking cimetidine (a medicine for stomach problems) at the same time as CHAMPIX, as this may cause increased levels of CHAMPIX in the blood.

Using CHAMPIX with other stop-smoking therapies

Consult your doctor before using CHAMPIX in combination with other stop-smoking therapies.

Using CHAMPIX with food and drink

There have been some reports of increased intoxicating effects of alcohol in patients taking CHAMPIX. However, it is not known whether CHAMPIX increases the effects of alcohol.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

It is preferable to avoid the use of CHAMPIX during pregnancy. Consult your doctor if you are planning to become pregnant.

Although it has not been studied, CHAMPIX may pass into human breast milk. You should consult your doctor or pharmacist before taking CHAMPIX.

Driving and using machines

CHAMPIX may be associated with dizziness, somnolence, and transient loss of consciousness. You should not drive, operate complex machinery, or engage in any other activity that may be potentially hazardous until you know whether this medicine affects your ability to perform these activities.

CHAMPIX contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per tablet, which is essentially “sodium-free”.

3. How to take CHAMPIX

Follow exactly the administration instructions of this medicine given by your doctor. In case of doubt, consult your doctor or pharmacist again.

You are more likely to stop smoking if you are motivated to do so. Your doctor or pharmacist can provide you with advice, support, and additional information to help you ensure that your attempt to stop smoking is successful.

Normally, before starting your treatment with CHAMPIX, you should decide on a date during the second week of treatment (between day 8 and day 14) when you will stop smoking. If you do not wish to or cannot set a date to stop smoking within these 2 weeks, you can choose your quit date within the next 5 weeks after starting treatment. You should write this date on the pack as a reminder.

CHAMPIX is available as white (0.5 mg) and light blue (1 mg) film-coated tablets. You will start with the white tablets and normally move to the light blue tablets. See below the table with the usual administration instructions that you should follow from Day 1.

If you have stopped smoking after 12 weeks of treatment, your doctor may recommend an additional 12 weeks of treatment with CHAMPIX 1 mg film-coated tablets twice a day to help you avoid relapse.

If you are unable or unwilling to stop smoking immediately, you should reduce your cigarette consumption during the first 12 weeks of treatment and stop at the end of this period. You should then continue to take CHAMPIX 1 mg film-coated tablets twice a day for another 12 weeks, making a total treatment duration of 24 weeks.

If you experience side effects that you cannot tolerate, your doctor may decide to reduce your dose temporarily or permanently to 0.5 mg twice a day.

If you have kidney problems, you should consult your doctor before taking CHAMPIX. You may need a lower dose.

CHAMPIX is taken by mouth.

The tablets should be swallowed whole with water or can be taken with or without food.

If you take more CHAMPIX than you should

If you have accidentally taken more CHAMPIX than your doctor prescribed, consult your doctor or go to the nearest hospital immediately. Take the pack with you.

If you forget to take CHAMPIX

Do not take a double dose to make up for a forgotten dose. 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 can. However, if it is almost time for your next dose, do not take the missed dose.

If you stop taking CHAMPIX

It has been shown in clinical trials that if you take all the doses of your medicine at the right times and for the recommended treatment period, your chances of stopping smoking will increase. Therefore, unless your doctor tells you to stop treatment, it is important to continue taking CHAMPIX as described in the table above.

In smoking cessation therapy, the risk of relapse may be high in the period immediately after the end of treatment. Temporarily, when you stop taking CHAMPIX, you may experience increased irritability, urge to smoke, depression, and/or sleep disturbances. Your doctor may decide to gradually reduce your dose of CHAMPIX at the end of treatment.

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

4. Possible side effects

Stopping smoking, with or without treatment, can cause various symptoms, which may include changes in mood (such as feeling depressed, irritable, frustrated, or anxious), insomnia, difficulty concentrating, decreased heart rate, and increased appetite or weight gain.

You should be aware of the possible occurrence of severe neuropsychiatric symptoms, such as agitation, depressed mood, or changes in behaviour during an attempt to stop smoking with or without CHAMPIX, and you should contact a doctor or pharmacist if you experience these symptoms.
