Varenicline belongs to the class of medications called smoking cessation therapies. It is used to help people quit smoking. Varenicline is intended to be used by adults in combination with quit-smoking education and counselling.
It works in the brain to reduce cravings and withdrawal symptoms. It also decreases the pleasure that people get from smoking. It is thought to have these effects by working at the same receptors that nicotine from cigarettes affects, although how varenicline exactly works is not clear.

The usual starting dose of varenicline is 0.5 mg once daily for the first 3 days, then 0.5 mg twice daily for the next 4 days, then continue on 0.5 mg twice daily or increase to 1 mg twice daily thereafter. The maximum dose of varenicline is 1 mg twice daily. Varenicline should be taken with a full glass of water, after eating.
Varenicline is intended to be used in combination with quit-smoking education and counselling. Treatment should start 1 to 2 weeks before the date the person has set to quit smoking (the "quit date") and continue for 12 weeks. For those who succeed in quitting smoking during this time, an additional 12 weeks of treatment may be recommended to reduce the risk that they will start smoking again. People who fail to quit smoking during the first 12-week treatment are encouraged to try again once they have identified and addressed the factors that may have caused them to have trouble quitting.
