What is the most appropriate smoking cessation medication for a patient presently tapering from clonazepam?

The most appropriate smoking cessation medication for a patient who is currently tapering from clonazepam is varenicline. This medication works by stimulating nicotine receptors in the brain, providing some of the nicotine effects to help relieve withdrawal symptoms and cravings associated with smoking cessation, while also blocking nicotine from attaching to these receptors, thereby reducing the pleasure derived from smoking.

Varenicline is generally well-tolerated, but it’s particularly useful for patients who may be at risk for mood-related side effects from other smoking cessation options, especially those with a history of anxiety or mood disorders, which may be relevant for someone tapering from a benzodiazepine like clonazepam. This makes varenicline a suitable choice since it does not have the same potential interactions with the central nervous system that might be of concern with other medications.

Bupropion may also be considered, but it has a risk of seizures, particularly in patients with a history of seizure disorders or those on fluctuating doses of CNS depressants like clonazepam, making varenicline a safer option during the
