OBJECTIVE: This article reviews research on post-acute alcohol withdrawal syndrome (PAWS) management. METHOD: We conducted a PRISMA (Preferred Reporting Items for Systematic Revision and Meta-Analyses)-guided scoping review of the published PAWS literature, searching six electronic databases (from their inception through December 2020) for English-language randomized and nonrandomized studies. RESULTS: A total of 16 treatment studies met the inclusion criteria. The strength of evidence overall for pharmacologic treatments is low, with often only short-term results being reported, small treatment samples used, or inconsistent results found. However, for negative affect and sleep symptoms, more evidence supports using gabapentinoids (gabapentin and pregabalin) and anticonvulsants (carbamazepine and oxcarbazepine). Although preliminary data support acamprosate, there were no controlled trials. Despite an older treatment trial showing some positive data for amitriptyline for mood, the clinical measures used were problematic, and side effects and safety profile limit its utility. Finally, there is no evidence that melatonin and other agents (homatropine, Proproten-100) show PAWS symptoms. CONCLUSIONS: Although there is some evidence for targeted pharmacotherapy for treating specific PAWS symptoms, there are few recent, robust, placebo-controlled trials, and the level of evidence for treatment efficacy is low.
