What is the recommended treatment plan for a patient experiencing alcohol withdrawal?

Management of Alcohol Withdrawal Syndrome

The recommended first-line treatment for alcohol withdrawal syndrome is long-acting benzodiazepines, with chlordiazepoxide (25-100 mg orally every 4-6 hours) or diazepam (5-10 mg PO/IV every 6-8 hours) being preferred options, along with mandatory thiamine supplementation (100-300 mg/day). 1

Assessment and Stratification

1. Use standardized assessment tools such as CIWA-Ar to guide treatment:

   • <8: Mild withdrawal
   • 8-14: Moderate withdrawal
   • ≥15: Severe withdrawal 1

2. Risk factors for severe withdrawal requiring inpatient management:

   • History of withdrawal seizures or delirium tremens
   • Significant medical or psychiatric comorbidities
   • Failed outpatient treatment 1
   • Chronic heavy drinking 2

Pharmacological Management

First-Line Treatment

• Benzodiazepines:

  • Chlordiazepoxide: 25-100 mg orally every 4-6 hours (50-100 mg initially for acute withdrawal, up to 300 mg/day) 1, 3
  • Diazepam: 5-10 mg PO/IV every 6-8 hours 1, 4
  • Lorazepam: 1-4 mg PO/IV/IM every 4-8 hours (preferred in hepatic dysfunction) 1

• Dosing Approach:

  • Symptom-triggered dosing is preferred over fixed-schedule dosing when adequate monitoring is available, as it results in lower total medication doses and shorter treatment duration 5
  • For severe withdrawal, front-loading may be necessary to achieve rapid symptom control 6

Adjunctive Treatments

• Essential supplements:

  • Thiamine: 100-300 mg/day to prevent Wernicke encephalopathy 1
  • Electrolyte replacement: particularly magnesium, potassium, and phosphate 1
  • Hydration: adequate fluid intake 1

• For specific symptoms:

  • Haloperidol: 0.5-5 mg PO/IM every 8-12 hours for agitation or psychotic symptoms not controlled by benzodiazepines (not as standalone treatment) 1
  • Carbamazepine: 200 mg every 6-8 hours as an alternative for seizure prevention 1
  • Phenobarbital: May be considered for high-risk withdrawal 1

Treatment Algorithm Based on Severity

Mild Withdrawal (CIWA-Ar <8)

• Outpatient management if no risk factors
• Symptom-triggered benzodiazepines
• Thiamine supplementation
• Adequate hydration and electrolyte replacement

Moderate Withdrawal (CIWA-Ar 8-14)

• Consider inpatient management, especially with comorbidities
• Regular benzodiazepine dosing with symptom-triggered supplementation
• Thiamine and electrolyte replacement
• Close monitoring of vital signs and withdrawal symptoms

Severe Withdrawal (CIWA-Ar ≥15)

• Inpatient management required
• Aggressive benzodiazepine treatment
• Consider ICU admission for:
  • Delirium tremens (typically begins 48-72 hours after last drink)
  • Withdrawal seizures
  • Hemodynamic instability
• IV fluids, electrolyte correction, and high-dose thiamine 1

Special Considerations

• Hepatic dysfunction: Prefer lorazepam over diazepam or chlordiazepoxide 1
• Elderly patients: Start with lower doses but don't withhold treatment 7
• Seizures during withdrawal: Benzodiazepines are more effective than anticonvulsants 2
• Delirium tremens: Requires intensive care with continuous monitoring of vital signs and respiratory support if necessary 2

Pitfalls and Caveats

• Avoid undertreatment: Inadequate benzodiazepine dosing can lead to progression to more severe withdrawal, seizures, or delirium tremens 8
• Avoid neuroleptics as monotherapy: They may lower seizure threshold 2
• Don't withhold benzodiazepines in liver disease: Adjust medication choice rather than withholding treatment 7
• Don't miss Wernicke encephalopathy: Always administer thiamine before glucose-containing fluids 2
• Avoid intramuscular diazepam: If IM route is necessary, use lorazepam or midazolam 7

Post-Acute Management

• After successful withdrawal management, consider medications to prevent relapse:

  • Acamprosate
  • Naltrexone
  • Disulfiram 1

• Refer patients to specialized addiction services and support groups 1

• Discharge only when clinically sober and able to safely care for themselves 1
