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

     
     

     CHAMPIX can also reduce the enjoyment of cigarettes if you do smoke when on treatment.

     
     

  2. What you need to know before you take CHAMPIX Do not take CHAMPIX

  Warnings and precautions

  Talk to your doctor or pharmacist before taking 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 or your family or if you develop suicidal thoughts or behaviours you should stop taking CHAMPIX and contact your doctor immediately for treatment assessment.

  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 medicines work. Therefore, in some cases an adjustment of the dose may be necessary. See below under ‘Other medicines and CHAMPIX’ for further details.

  
  

  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 disorder. If you have a history of psychiatric disorder you should discuss this with your doctor.

  
  

  Heart symptoms

  New or worse heart or blood vessel (cardiovascular) problems have been reported primarily in people who already have cardiovascular 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 or stroke.

  
  

  Seizures

  Tell your doctor if you have experienced seizures or have epilepsy before your start CHAMPIX treatment. Some people have reported seizures while taking 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 serious allergic reaction: swelling of the face, lips, tongue, gums, throat or body and/or difficulty breathing, wheezing.

  
  

  Skin reactions

  Potentially life-threatening skin rashes (Stevens-Johnson syndrome and Erythema Multiforme) have been reported with the use of CHAMPIX. If you develop a rash or if your skin starts to peel or blister you should stop taking CHAMPIX and seek emergency medical help.

  
  

  Children and adolescents

  CHAMPIX is not recommended for use in paediatric patients as efficacy was not demonstrated.

  
  

  Other medicines and CHAMPIX

  Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

  
  

  In some cases as a result of stopping smoking, with or without CHAMPIX, an adjustment of the dose of other medicines 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.

  
  

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

  
  

  Use of CHAMPIX with other therapies for smoking cessation

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

  
  

  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 if CHAMPIX actually increases alcohol intoxication.

  
  

  Pregnancy and breast-feeding

  If you are pregnant or breast-feeding, 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 while you are pregnant. Talk to your doctor if you are intending to become pregnant.

  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 be linked with dizziness, sleepiness and transient loss of consciousness. You should not drive, operate complex machinery or engage in any other potentially hazardous activities 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, that is to say essentially ‘sodium-free’.

  
  

  1. How to take CHAMPIX

     
     

     Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

     
     

     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.

     
     

     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 comes as a white tablet (0.5 mg) and a light blue tablet (1 mg). You start with the white tablet and then usually go to the light blue tablet. See the chart below for the usual dosing instructions which you should follow from Day 1.

     
     

     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.

     
     

     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 to help avoid returning back to smoking.

     
     

     If you are not able or willing to quit smoking straight away, you should 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.

     
     

     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.

     
     

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

     
     

     Champix is for oral use.

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

     
     

     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 within 3-4 hours before 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.

     
     

     In smoking cessation therapy, risk of returning to smoking may be elevated in the period immediately following the end of treatment. 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.

     
     

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

     
     

  2. Possible side effects

     Like all medicines, this medicine can cause side effects, although not everybody gets them. 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 and increased appetite or weight gain.

     
     

     You should be aware of the possible emergence of serious neuropsychiatric symptoms, such as agitation, depressed mood, or changes in behaviour during a quit attempt with or without CHAMPIX and you should contact a doctor or pharmacist if you experience such symptoms.
