There have been reports of depression, suicidal thoughts and behaviour, and attempted suicide in patients taking varenicline. If you are taking this medicine 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 varenicline and contact your doctor immediately for an assessment of your treatment.
Effects of stopping smoking
The effects of the changes in your body as a result of stopping smoking, with or without treatment with varenicline, may alter the action of other medicines. Consequently, in some cases it may be necessary to adjust the dose of other medicines. See below for more details in “Other medicines and Varenicline Cinfa”.
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. Inform your doctor if you experience any change in symptoms during treatment with this medicine. If you experience symptoms of a heart attack or stroke, seek emergency medical help immediately.
Seizures
Before starting treatment with Varenicline Cinfa, inform your doctor if you have had seizures or if you are epileptic. Some people have observed seizures during treatment with this medicine.
Hypersensitivity reactions
Stop taking varenicline and inform 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 rash (Stevens-Johnson syndrome and erythema multiforme) with the use of varenicline. If you develop a rash or blisters or your skin peels, you should stop taking this medicine and seek urgent medical attention.
Children and adolescents
Varenicline is not recommended for use in paediatric patients as its efficacy has not been demonstrated.
Other medicines and Varenicline Cinfa
Inform 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 Varenicline Cinfa, 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 this medicine, as this may cause increased levels of varenicline in the blood.
Use of Varenicline Cinfa with other smoking cessation therapies
Consult your doctor before using this medicine in combination with other smoking cessation therapies.
Taking Varenicline Cinfa with food, drinks, and alcohol

Normally, before starting treatment with Varenicline Cinfa, 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.
Varenicline Cinfa is available as 0.5 mg and 1 mg film-coated tablets. You will start with the 0.5 mg tablets and normally move to the 1 mg tablets. See below for 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 Varenicline Cinfa 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 tobacco consumption during the first 12 weeks of treatment and stop at the end of this period. You should then continue to take Varenicline Cinfa 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 the dose temporarily or permanently to 0.5 mg twice a day.
If you have kidney problems, you should consult your doctor before taking this medicine. You may need a lower dose.
Varenicline Cinfa is taken by mouth.
The tablets should be swallowed whole with water or can be taken with or without food.
If you take more Varenicline Cinfa than you should
In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicological Information Service, telephone 91 562 04 20, indicating the medicine and the amount taken.
If you forget to take Varenicline Cinfa
Do not take a double dose to make up for forgotten doses. It is important that you take varenicline 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 Varenicline Cinfa
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 varenicline as described in the table above.
In smoking cessation therapy, the risk of relapse to smoking may be high in the period immediately after the end of treatment. Temporarily, when you stop taking varenicline, you may experience increased irritability, urge to smoke, depression, and/or sleep disturbances. Your doctor may decide to gradually reduce your dose of varenicline at the end of treatment.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
