What is the recommended protocol for managing alcohol withdrawal?

Alcohol Withdrawal Management Protocol

The recommended protocol for managing alcohol withdrawal is a symptom-triggered approach using benzodiazepines, particularly diazepam, with CIWA-Ar score assessment guiding treatment decisions and appropriate adjunctive therapies including thiamine supplementation. 1

Assessment and Risk Stratification

• Use the Clinical Institute Withdrawal Assessment for Alcohol Scale, Revised (CIWA-Ar) to assess severity:

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

• Risk factors for severe withdrawal requiring closer monitoring:

  • History of previous withdrawal seizures
  • History of delirium tremens
  • Chronic heavy alcohol use 1, 2
  • Multiple previous withdrawal episodes 1

Pharmacological Management

First-Line Treatment: Benzodiazepines

• Diazepam is the preferred benzodiazepine for most patients due to its long half-life providing a self-tapering effect 1, 3

  • Initial dose: 10 mg IV for acute agitation, tremor, or impending delirium tremens
  • Maintenance: 5-10 mg IV every 3-4 hours as needed 1
  • For outpatient management: 10 mg PO, 3-4 times during first 24 hours, reducing to 5 mg, 3-4 times daily as needed 3

• For patients with hepatic dysfunction, lorazepam is preferred 1

• Treatment approaches:

  • Symptom-triggered approach (recommended): Medication given based on CIWA-Ar scores
  • Front-loading: Higher initial doses followed by scheduled doses
  • Fixed-schedule tapering: Less preferred than symptom-triggered 1, 4

Alternative Medications for Special Situations

• For mild withdrawal symptoms in outpatient setting: Carbamazepine or gabapentin may be considered 5
• For benzodiazepine-refractory delirium tremens: Consider phenobarbital, propofol, or dexmedetomidine 1
• For hallucinations/agitation not controlled by benzodiazepines: Haloperidol 0.5-5 mg PO/IM every 8-12 hours 1

Essential Adjunctive Treatments

1. Thiamine supplementation: 100-300 mg/day IV to prevent Wernicke encephalopathy 1, 2

   • High doses must be used to compensate for poor absorption
   • IV administration is best for patients with poor nutritional status 2

2. Electrolyte replacement:

   • Focus on magnesium, potassium, and phosphate 1
   • Ensure adequate hydration 1

3. Supportive care:

   • Individual support and effective communication to reduce risk of severe withdrawal 2
   • Regular monitoring of vital signs 2
   • Create a reassuring environment 2

Management of Complications

• Seizures: Oral benzodiazepines are the most effective treatment for withdrawal seizures 1, 2

  • CT scan recommended for first alcohol withdrawal seizure, focal neurological deficits, persistent altered mental status, or history of head trauma 1

• Delirium tremens: Requires intensive monitoring

  • Continuous monitoring of vital signs
  • Fluid-electrolyte support
  • Respiratory support if necessary 2

Outpatient vs. Inpatient Management

• Outpatient management appropriate for:

  • Mild to moderate withdrawal symptoms
  • No history of severe withdrawal
  • No significant comorbidities
  • Reliable support system 5

• Inpatient management indicated for:

  • Severe withdrawal symptoms (CIWA-Ar ≥15)
  • History of withdrawal seizures or delirium tremens
  • Significant medical or psychiatric comorbidities
  • Pregnancy
  • Unreliable social support 1, 5

Long-term Management

• 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
  • Provide comprehensive psychosocial support including individual psychotherapy, psychoeducation, group therapy, and cognitive behavioral therapy 1

Important Caveats

• Avoid neuroleptics as standalone treatment for alcohol withdrawal as they may increase seizure risk 2
• Betablockers may increase the risk of hallucinations 2
• Clonidine may increase the risk of nightmares 2
• Limit benzodiazepine treatment to a maximum of 7 days when possible to prevent dependence 2, 6
• Monitor outpatients daily for up to five days after their last drink 5
• Gradual tapering is necessary when discontinuing benzodiazepines to prevent withdrawal reactions 3
