Studies of varenicline have shown that this new agent has improved efficacy compared with existing treatments that aid smoking cessation. Compared to bupropion, it matches control of withdrawal symptoms but also reduces cigarette satisfaction and it is safe when used in suitable patients. Despite these benefits, varenicline is neither side effect free nor a guarantee of successful smoking cessation. What is important is that clinicians caring for smokers develop competence and confidence with the use of this new drug.
