What is the recommended protocol for outpatient management of alcohol withdrawal?

Outpatient Management Protocol for Alcohol Withdrawal

For outpatient management of alcohol withdrawal syndrome, a symptom-triggered approach using benzodiazepines is recommended, with diazepam as the preferred agent for most patients and lorazepam for those with hepatic dysfunction. 1

Patient Selection for Outpatient Management

Outpatient management is appropriate for patients with:

• Mild to moderate withdrawal symptoms (CIWA-Ar score <15)
• No history of withdrawal seizures or delirium tremens
• No significant comorbidities
• Reliable support system
• Ability to return for daily follow-up for up to 5 days 2

Patients with severe symptoms (CIWA-Ar score ≥15), history of seizures, or delirium tremens should be managed in an inpatient setting 1, 2.

Assessment and Monitoring

1. Severity Assessment:

   • Use the Clinical Institute Withdrawal Assessment for Alcohol Scale, Revised (CIWA-Ar)
   • Categorize withdrawal severity:
     • Mild: CIWA-Ar <8
     • Moderate: CIWA-Ar 8-14
     • Severe: CIWA-Ar ≥15 1

2. Daily Monitoring:

   • Patients should be seen daily for up to 5 days after their last drink
   • Monitor vital signs, withdrawal symptoms, and medication response 2

Pharmacological Management

Primary Treatment: Benzodiazepines

For Mild to Moderate Withdrawal (CIWA-Ar <15):

Diazepam (preferred for most patients):

• Initial dose: 10 mg orally
• Follow with 5-10 mg every 3-4 hours as needed based on symptoms
• For acute alcohol withdrawal: 10 mg, 3-4 times during first 24 hours, reducing to 5 mg, 3-4 times daily as needed 1, 3

Lorazepam (for patients with hepatic dysfunction):

• 1-2 mg orally every 4-6 hours as needed based on symptoms

Chlordiazepoxide (alternative):

• Initial dose: 50-100 mg orally
• Repeated doses as needed until agitation is controlled (up to 300 mg per day)
• Then reduce to maintenance levels 4

Alternative or Adjunctive Medications

For mild withdrawal symptoms or as adjuncts:

• Carbamazepine: 200 mg orally 4 times daily for 5 days, with gradual taper
• Gabapentin: 300-600 mg orally 3 times daily for 3-5 days, with gradual taper 2

Essential Adjunctive Treatments

1. Thiamine Supplementation:

   • 100-300 mg daily to prevent Wernicke encephalopathy 1

2. Electrolyte Replacement:

   • Particularly magnesium, potassium, and phosphate as indicated by laboratory results 1

3. Adequate Hydration:

   • Encourage oral fluid intake but avoid excessive water-sodium intake in patients with heart disease 5

Supportive Care

1. Individual Support and Communication:

   • Provide reassurance and clear information about the withdrawal process
   • Ensure a calm, quiet environment 5

2. Management of Gastrointestinal Symptoms:

   • For fecal incontinence: Fiber supplementation and loperamide (2 mg) as needed
   • For nausea/vomiting: Antiemetics as needed 1

Follow-up and Long-term Management

1. Daily follow-up for up to 5 days to monitor symptoms and adjust treatment 2

2. After successful withdrawal management:

   • Consider medications to prevent relapse (acamprosate, naltrexone, disulfiram)
   • Refer to specialized addiction services
   • Recommend mutual help groups such as Alcoholics Anonymous 1

3. Psychiatric consultation for evaluation and long-term treatment planning 1

Common Pitfalls and Caveats

1. Underestimation of withdrawal severity:

   • Always err on the side of caution when determining outpatient vs. inpatient management
   • Have a low threshold for hospitalization if symptoms worsen

2. Inadequate benzodiazepine dosing:

   • Insufficient dosing can lead to progression to severe withdrawal
   • The diazepam loading approach (multiple doses until symptoms subside) has been shown to be effective and safe 6

3. Failure to address vitamin deficiencies:

   • Thiamine deficiency is common and can lead to Wernicke encephalopathy
   • High doses must be used to compensate for poor absorption 5

4. Neglecting long-term treatment:

   • Withdrawal management is only the first step in treating alcohol use disorder
   • Long-term treatment planning should begin during withdrawal management 1, 7

5. Inappropriate use of antipsychotics:

   • Antipsychotics should not be used as standalone treatment for alcohol withdrawal as they may increase seizure risk 1, 5
