Treatment of Alcohol Withdrawal Syndrome
Benzodiazepines are the gold standard treatment for alcohol withdrawal syndrome (AWS), with long-acting benzodiazepines like diazepam being preferred for most patients due to their rapid onset and self-tapering properties. 1
Initial Assessment and Treatment Setting
Severity Assessment
- Use Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) scale to assess severity:
- Score >8: Moderate AWS
- Score ≥15: Severe AWS 1
Treatment Setting Decision
Outpatient management is appropriate for:
Inpatient management is required for:
- Severe AWS with complications (delirium, seizures)
- History of withdrawal seizures or delirium tremens
- Significant comorbidities (psychiatric or physical)
- Inadequate social support
- Failed outpatient treatment 1
Pharmacological Treatment
First-Line Therapy: Benzodiazepines
For Most Patients:
- Diazepam (preferred): 10 mg PO 3-4 times during first 24 hours, then reducing to 5 mg 3-4 times daily as needed 3
For Special Populations:
- Lorazepam: 1-4 mg PO/IV/IM every 4-8 hours 1
Adjunctive Therapies:
Thiamine: 100-300 mg/day for all AWS patients
Carbamazepine: 200 mg PO every 6-8 hours
Gabapentin: Alternative for mild symptoms or as adjunct therapy 2
Haloperidol: 0.5-5 mg PO/IM every 8-12 hours
Supportive Care:
- Fluid and electrolyte replacement (especially magnesium)
- Comfortable environment
- Close monitoring of vital signs 1
Treatment Duration and Monitoring
- Monitor patients daily for up to 5 days after last drink 2
- Taper benzodiazepines gradually to prevent withdrawal reactions 3
- Limit benzodiazepine treatment to 7-14 days to prevent dependence 1, 6
Common Pitfalls to Avoid
Using CIWA protocol for diagnosis: The CIWA is for severity assessment and treatment planning, not for diagnosis of AWS 1
Using antipsychotics as primary treatment: These increase seizure risk and should only be used as adjuncts to benzodiazepines 1, 6
Failing to provide thiamine: Must be given before glucose administration to prevent precipitating acute thiamine deficiency 1
Inadequate benzodiazepine dosing: Undertreating can lead to progression to seizures and delirium tremens 7
Prolonged benzodiazepine use: Should be limited to 7-14 days to prevent dependence 1
Long-Term Management
After acute withdrawal management, consider:
