Which patient population might benefit most from varenicline?

• A. Individuals who have never tried quitting.
• B. Anyone with any psychiatric history.
• C. Only those who have successfully quit with NRT.
• D. Individuals seeking to maximize quit rates who do not have contraindicating psychiatric conditions or suicidality; those who have failed first-line NRT.

Answer: (D)

Varenicline helps you quit by partially activating the same nicotine receptor, which eases withdrawal and also blunts the rewarding effects of smoking. Because this mechanism tends to produce higher quit rates than many other options, it’s especially helpful for someone who wants to maximize their chances of quitting. At the same time, it carries a risk of mood changes or suicidality, so it’s prescribed only when there are no contraindicating psychiatric conditions or suicidality. It’s often used after first-line nicotine replacement therapy has failed, making it a logical next step for someone who has already tried NRT without success. In short, the best-fit patient is someone who aims for the highest quit rate, has no psychiatric contraindications or suicidality, and has not succeeded with first-line NRT.
