How to Use

Treatment with Champix (varenicline) works best on smokers who are highly motivated to stop smoking. Counseling is recommended before you start using the treatment. You will also need to pick a date on which you will stop smoking. Studies show it is possible to recover after stopping smoking 8 to 35 days after starting Champix treatment.

The treatment will take 12 weeks. The patient starts by taking a 0.5mg tablet, once a day for the first 3 days. The dose is then increased to two tablets of 0.5mg a day for the subsequent 4 days. The patient then takes two tablets of 1mg a day for the remaining 11 weeks.

If a patient does not successfully stop smoking after the 12 weeks, your doctor may recommend an additional treatment of 12 more weeks. The dose may be changed from time to time to achieve the best results.
