What is the recommended treatment for alcohol withdrawal?

Treatment of Alcohol Withdrawal Syndrome

Benzodiazepines are the gold standard treatment for alcohol withdrawal syndrome, with short-acting benzodiazepines (lorazepam, oxazepam) preferred in patients with hepatic dysfunction. 1, 2

Assessment and Severity Classification

Severity should be assessed using the Clinical Institute Withdrawal Assessment (CIWA) scale:

• CIWA ≤7: Mild withdrawal - Monitor, may not require medication
• CIWA 8-14: Moderate withdrawal - Initiate benzodiazepine treatment
• CIWA ≥15: Severe withdrawal - Aggressive benzodiazepine treatment, consider inpatient management 2

Pharmacological Management

First-Line Treatment: Benzodiazepines

1. Choice of Benzodiazepine:

   • Patients with normal liver function: Long-acting benzodiazepines (diazepam, chlordiazepoxide) provide more protection against seizures and delirium 1
   • Patients with hepatic dysfunction or elderly: Short-acting benzodiazepines (lorazepam, oxazepam) are safer 1

2. Dosing for Diazepam (standard option):

   • Acute alcohol withdrawal: 10 mg, 3-4 times during first 24 hours, reducing to 5 mg, 3-4 times daily as needed 3
   • Symptom-triggered therapy is preferred over fixed-schedule dosing to minimize total benzodiazepine exposure

3. Administration Routes:

   • Oral: Preferred when possible
   • Intravenous: For severe withdrawal or when rapid control is needed
   • Intramuscular: Avoid diazepam due to erratic absorption; use lorazepam or midazolam if IM route is necessary 4

Essential Adjunctive Treatment

• Thiamine supplementation: 100-300 mg/day before any glucose-containing solutions to prevent Wernicke's encephalopathy 1, 2
• Rehydration and electrolyte correction: Address imbalances, particularly potassium, sodium, and chloride 2

Treatment Setting

• Inpatient treatment: Recommended for severe AWS, history of withdrawal seizures or delirium tremens, significant comorbidities, or failed outpatient treatment 2
• Outpatient treatment: Appropriate for patients with mild to moderate withdrawal, no history of seizures or delirium tremens, adequate social support, and no significant comorbidities 2

Management of Complications

• Seizures: Benzodiazepines are effective for prevention and treatment of withdrawal seizures 5
• Hallucinations: Oral benzodiazepines are the best-assessed treatment 5
• Delirium tremens: Benzodiazepines are more effective than neuroleptics in preventing delirium-related mortality 5

Post-Acute Withdrawal Management

After acute withdrawal management, consider medications to maintain abstinence:

• Baclofen: May be considered for patients with cirrhosis 2
• Gabapentin: May be used as adjunctive therapy for post-acute withdrawal symptoms 2
• Avoid: Naltrexone and disulfiram due to hepatotoxicity risk 2

Important Considerations and Pitfalls

• Benzodiazepines should be used for a maximum of 7 days to minimize adverse effects and dependence risk 5
• Neuroleptics should not be used as standalone treatment for AWS as they may lower seizure threshold 2
• Regular monitoring of vital signs and withdrawal symptoms is essential during treatment
• Gradual tapering of benzodiazepines is recommended to prevent withdrawal reactions 3
• Anticonvulsants like carbamazepine may be alternatives to benzodiazepines in selected cases, but have limited usefulness in alcoholics with severe hepatic complications 6

The evidence strongly supports benzodiazepines as the cornerstone of alcohol withdrawal treatment, with the specific agent chosen based on liver function status and individual patient factors.
