Quadruple pharmacotherapy for alcohol use disorder tolerable yet insufficient: a case report.

Background: Combinations of alcohol use disorder (AUD) medications have been investigated, but few if any reports describe patients maintained on more than two options at the same time.

Case presentation: We report a case of a middle-aged man hospitalized with gastrointestinal bleeding and acute kidney injury who had been maintained on four AUD medications (naltrexone, acamprosate, disulfiram, and gabapentin) and multiple psychiatric medications simultaneously as an outpatient. Direct quotations of his experiences with each AUD medication are included, revealing some deviations from what was prescribed as well as nuanced perceptions of effects. Overall, he tolerated the regimen well, but its AUD effects were insufficient to prevent several episodes of returning to alcohol use. He had very high hospital utilization. This prompted the initiation of an involuntary commitment, which began a period of at least six months of sobriety.

Conclusions: Quadruple pharmacotherapy for AUD may be well tolerated and supportive of recovery for an extended period of time. However, for our patient the regimen ultimately failed to prevent multiple episodes of returning to alcohol use and serious medical complications. In refractory cases like this, more intensive interventions such as involuntary commitment can be considered.
