Contents of the pack and other information
Varenicline Kern Pharma contains the active substance varenicline. Varenicline is a medicine used in adults to help them stop smoking.
Varenicline can help alleviate the anxiety and withdrawal symptoms associated with stopping smoking.
Varenicline may also reduce the pleasure you get from smoking if you smoke during treatment.
Warnings and precautions
Talk to your doctor or pharmacist before you start taking varenicline.
There have been reports of depression, suicidal thoughts and behaviour, and attempted suicide in patients taking varenicline. If you are taking varenicline 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 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 varenicline, 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 Varenicline Kern Pharma".
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 changes in symptoms during treatment with varenicline. If you experience symptoms of a heart attack or stroke, seek emergency medical help immediately.
Seizures
Before starting treatment with varenicline, tell your doctor if you have had seizures or if you are epileptic. Some people have observed seizures during treatment with varenicline.
Hypersensitivity reactions
Stop taking varenicline 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 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 varenicline 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 Kern Pharma
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 varenicline, it may be necessary to adjust the dose of other medicines. Examples include theophylline (a medicine for treating respiratory problems), warfarin (a medicine for reducing blood clotting), and insulin (a medicine for treating diabetes). If you have any doubts, talk to 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 varenicline, as this may cause increased levels of varenicline in the blood.
Use of Varenicline Kern Pharma with other smoking cessation therapies
Consult your doctor before using varenicline in combination with other smoking cessation therapies.
Taking Varenicline Kern Pharma with alcohol
There have been some reports of increased intoxicating effects of alcohol in patients taking varenicline. However, it is not known whether varenicline 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.
Varenicline should be avoided during pregnancy. Talk to your doctor if you plan to become pregnant.
Although it has not been studied, varenicline may pass into human breast milk. You should talk to your doctor or pharmacist before taking varenicline.
Driving and using machines
Varenicline may be associated with dizziness, somnolence, and transient loss of consciousness. You should not drive, operate complex machinery, or engage in any other potentially hazardous activity until you know whether this medicine affects your ability to perform these activities.
Varenicline Kern Pharma contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per tablet, which is essentially "sodium-free".
Follow the instructions for administration of this medicine exactly as indicated by your doctor. If you are in 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 treatment with varenicline, 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 stop-smoking date within the next 5 weeks after starting treatment. You should write this date on the pack as a reminder.
Varenicline Kern Pharma is available as white tablets (0.5 mg) and light blue tablets (1 mg). You will start with the white tablets and normally switch to the light blue tablets. See the table below for the usual administration instructions to follow from Day 1.
Week 1 | Dose |
Day 1 - 3 | From day 1 to day 3, you should take one white Varenicline Kern Pharma 0.5 mg film-coated tablet once a day. |
Day 4 - 7 | From day 4 to day 7, you should take one white Varenicline Kern Pharma 0.5 mg film-coated tablet twice a day, once in the morning and once in the evening, approximately at the same time each day. |
Week 2 | Dose |
Day 8 – 14 | From day 8 to day 14, you should take one light blue Varenicline Kern Pharma 1 mg film-coated tablet twice a day, once in the morning and once in the evening, approximately at the same time each day. |

Day 15 - End of treatment | From day 15 to the end of treatment, you should take one light blue Varenicline Kern Pharma 1 mg film-coated tablet twice a day, once in the morning and once in the evening, approximately at the same time each day. |
If you have stopped smoking after 12 weeks of treatment, your doctor may recommend an additional 12 weeks of treatment with varenicline 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 taking varenicline 1 mg film-coated tablets twice a day for another 12 weeks, making a total of 24 weeks of treatment.
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 talk to your doctor before taking varenicline. You may need a lower dose.
Varenicline Kern Pharma is taken by mouth.
The tablets should be swallowed whole with water and can be taken with or without food.
If you take more Varenicline Kern Pharma than you should
If you have accidentally taken more varenicline than your doctor prescribed, talk to your doctor immediately, go to the nearest hospital, or call the Poison Information Service on 91 562 04 20, stating the medicine and the amount taken. Bring your tablet pack with you.
If you forget to take Varenicline Kern Pharma
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 between 3 and 4 hours before your next dose, do not take the missed tablet.
If you stop taking Varenicline Kern Pharma
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 and as described above, you will increase your chances of stopping smoking. Therefore, unless your doctor tells you to stop treatment, it is important to keep taking varenicline as directed.
In smoking cessation therapy, the risk of relapse may be high in the period immediately following the end of treatment. Temporarily, when you stop taking varenicline, you may experience increased irritability, need 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 other questions about the use of this medicine, ask your doctor or pharmacist.

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