Summary
This open-label study will evaluate hydroxyzine, a first-generation antihistamine, combined with varenicline, to help smokers abstain from smoking during a 12-week trial period by diminishing the nausea, stress, anxiety, and sleep disturbances associated with the use of varenicline and with nicotine withdrawal.
