Gabapentin for Alcohol Use Disorder

Current Guideline Recommendations for Alcohol Use Disorder

  • The American Association for the Study of Liver Diseases recommends benzodiazepines as the gold standard for treating alcohol withdrawal syndrome (AWS) 1, 3, 4
  • The American College of Gastroenterology recommends acamprosate for maintaining abstinence after withdrawal, as it reduces withdrawal effects and craving, effective at maintaining abstinence 3, 5
  • The American Society of Addiction Medicine recommends naltrexone for maintaining abstinence, as it decreases dopamine concentration, dampens reward pathway activation, decreases excessive drinking and recurrence rates 3, 5
  • The European Association for the Study of the Liver recommends baclofen, a GABAB receptor agonist, for maintaining abstinence, particularly in patients with liver cirrhosis 3, 6

Clinical Approach to Alcohol Use Disorder Treatment

  • The American Medical Association recommends benzodiazepines as the first-line treatment for acute alcohol withdrawal 1, 3, 4
  • The American Academy of Family Physicians recommends lorazepam (1-4 mg every 4-8 hours) for patients with severe AWS, liver failure, or other serious comorbidities 4, 7
  • The National Institute on Alcohol Abuse and Alcoholism recommends acamprosate (1,998 mg/day for ≥60 kg patients) for 3-6 months for maintaining abstinence 3
  • The Substance Abuse and Mental Health Services Administration recommends naltrexone (50 mg daily after initial titration) for 3-6 months for maintaining abstinence (contraindicated in ALD) 3
  • The American College of Physicians recommends baclofen (up to 80 mg/day) particularly for patients with liver disease 3, 6
  • The American Psychological Association recommends individual psychotherapy, psychoeducation, group therapy, and cognitive behavioral therapy to accompany pharmacological treatment 5, 8

Important Caveats

  • The National Institutes of Health recommends thiamine supplementation (100-300 mg/day for 4-12 weeks) to prevent Wernicke encephalopathy in patients with alcohol use disorder 3, 4
  • The American Psychiatric Association recommends psychiatric consultation for evaluation, treatment, and long-term planning of alcohol abstinence 3
