Abstract

EVIDENCE-BASED ANSWER

No. Naltrexone does not have a significant effect on long-term (6 month) smoking abstinence (SOR: A, systematic review of quality RCTs). Adding naltrexone to nicotine replacement therapy (NRT) results in better 12-week quit rates in heavy alcohol drinkers, but not moderate to light drinkers or nondrinkers (SOR: B, RCT). Naltrexone 25 mg along with NRT results in less weight gain during smoking cessation therapy compared with nicotine replacement alone, but higher doses do not (SOR: B, RCT).
