Outpatient Management of Moderate to Severe Alcohol Use Disorder
For adults with moderate to severe alcohol use disorder, initiate naltrexone 50 mg daily as first-line pharmacotherapy combined with psychosocial interventions, reserving inpatient management only for those at risk of severe withdrawal complications, lacking adequate social support, or with concurrent serious medical/psychiatric disorders. 1
Initial Assessment and Risk Stratification
Determine treatment setting based on withdrawal risk and social factors:
Outpatient management is appropriate for patients with: 1
- Mild-to-moderate withdrawal symptoms (CIWA-Ar score <15)
- Stable medical and psychiatric status
- Adequate social support and reliable supervision
- No history of severe withdrawal complications (seizures, delirium tremens)
Inpatient management is required for patients with: 2, 1
- Risk of severe withdrawal complications
- Concurrent serious physical or psychiatric disorders
- Inadequate social support or unreliable supervision
- CIWA-Ar scores ≥15 indicating severe withdrawal
Acute Withdrawal Management (Days 1-7)
Benzodiazepines are the gold standard first-line treatment for alcohol withdrawal syndrome: 1, 3
Long-acting benzodiazepines (diazepam, chlordiazepoxide) are preferred for most patients as they provide superior protection against seizures and delirium tremens through gradual self-tapering 1
Switch to intermediate-acting benzodiazepines (lorazepam, oxazepam) in patients with advanced age, hepatic dysfunction, or severe medical comorbidities to avoid drug accumulation 1, 3
Use symptom-triggered dosing guided by CIWA-Ar scale rather than fixed-dose schedules to prevent drug accumulation while ensuring adequate symptom control 1
- CIWA-Ar score >8: moderate withdrawal requiring pharmacological intervention
- CIWA-Ar score ≥15: severe withdrawal requiring aggressive treatment
Limit benzodiazepine prescriptions to 7-14 days maximum to avoid dependence, particularly critical in patients with alcohol use disorder who are at higher risk of benzodiazepine abuse 1, 3
Thiamine supplementation is mandatory: 1, 3
- All patients should receive oral thiamine supplementation
- High-risk patients (malnourished, severe withdrawal) or those with suspected Wernicke's encephalopathy require parenteral thiamine immediately—do not delay administration as this can lead to irreversible neurological damage 1
Long-Term Pharmacotherapy for Relapse Prevention (After Acute Withdrawal Resolves)
Naltrexone 50 mg daily is the first-line medication for most patients: 1, 4, 5
- Reduces return to any drinking by 5% and binge-drinking risk by 10% 1, 5
- Initiate after ensuring patient is opioid-free for minimum 7-10 days (including tramadol) 4
- Contraindicated in patients with alcoholic liver disease or cirrhosis due to hepatotoxicity risk 1, 3
Alternative pharmacotherapy options:
Acamprosate 666 mg three times daily is preferred for patients with liver disease, as it has no reported hepatotoxicity and undergoes renal excretion only 1, 3
Baclofen 30-60 mg/day (up to 80 mg/day) is particularly effective for patients with cirrhosis, reducing alcohol craving and maintaining abstinence 1, 3
Disulfiram should be avoided in patients with severe alcoholic liver disease due to possible hepatotoxicity 3, 6
Psychosocial Interventions (Concurrent with Pharmacotherapy)
Combine pharmacotherapy with structured psychosocial support for optimal outcomes: 1
Offer cognitive-behavioral therapy (CBT), motivational enhancement therapy (MET), or motivational interviewing as part of comprehensive treatment 1
Encourage engagement with mutual help groups like Alcoholics Anonymous as adjunctive support 1, 3
Brief interventions (15-minute personalized counseling) are effective in primary care for reducing excessive consumption 3
Monitoring and Follow-Up
Daily monitoring is required during acute withdrawal phase: 7, 8
- Monitor patients daily for up to 5 days after last drink to verify symptom improvement and evaluate need for additional treatment 7
- Assess CIWA-Ar scores to guide treatment intensity adjustments 1
Long-term follow-up structure: 9
- Treatment should be viewed as chronic disease management requiring ongoing care, not a single intervention
- Provide continuum of care that blurs distinction between initial and continuing care to prolong treatment participation 9
Critical Pitfalls to Avoid
Medication-related errors: 1, 3
- Never prescribe naltrexone or disulfiram in patients with alcoholic liver disease or cirrhosis—use acamprosate or baclofen instead 1, 3
- Never extend benzodiazepine prescriptions beyond 7-14 days as this increases dependence risk 1, 3
- Never delay thiamine administration in high-risk patients or those with suspected Wernicke's encephalopathy 1
Assessment errors: 2
- Screen all patients with substance use disorders for intimate partner violence, as rates exceed 50% in some settings with drug use disorders 2
- Screen for comorbid mental health disorders, as primary disorders generally predate substance misuse and require standard psychological and pharmacologic therapies 2
