Management of Alcoholic Withdrawal Symptoms
Benzodiazepines are the gold standard first-line treatment for alcohol withdrawal syndrome, with long-acting agents like diazepam (10 mg every 6-8 hours) or chlordiazepoxide (25-100 mg every 4-6 hours) preferred for most patients to prevent seizures and delirium tremens. 1, 2
Initial Assessment and Treatment Setting
Admit patients to the hospital if they have: 3, 4
- Delirium tremens or withdrawal seizures
- History of severe withdrawal complications
- Significant medical or psychiatric comorbidities
- Recent head trauma
- High levels of recent alcohol consumption
- Failed outpatient treatment
Outpatient management is appropriate for mild to moderate withdrawal without these risk factors, though psychiatric consultation is recommended for evaluation and long-term abstinence planning. 3, 5
Pharmacological Management
First-Line: Benzodiazepines
For most patients, use long-acting benzodiazepines: 3, 1
- Diazepam: 10 mg orally, IV, or IM every 6-8 hours for symptomatic relief in acute alcohol withdrawal, reducing to 5 mg three or four times daily as needed 6
- Chlordiazepoxide: 25-100 mg orally every 4-6 hours 1, 4
Long-acting agents provide superior protection against seizures and delirium tremens due to their extended duration of action and self-tapering properties. 3, 2
Special Populations: Short/Intermediate-Acting Benzodiazepines
Switch to lorazepam for patients with: 3, 1, 4
- Hepatic dysfunction or cirrhosis
- Advanced age (elderly patients)
- Respiratory failure
- Obesity
- Recent head trauma
- Other serious medical comorbidities
Lorazepam dosing: Start at 6-12 mg/day (typically 1-4 mg every 4-8 hours), then taper following resolution of withdrawal symptoms. 3, 2 Lorazepam is safer in liver disease because it doesn't rely on hepatic oxidation for metabolism. 4
Duration and Tapering
Taper benzodiazepines gradually after withdrawal symptoms resolve, limiting total treatment duration to 10-14 days maximum to avoid benzodiazepine dependence. 2, 4
Essential Adjunctive Treatments
Thiamine (Critical)
Administer thiamine 100-300 mg/day to ALL patients with alcohol withdrawal to prevent Wernicke encephalopathy. 3, 1, 4
Critical timing: Give thiamine BEFORE any glucose-containing IV fluids to prevent precipitating acute thiamine deficiency. 2, 4 Continue thiamine for 2-3 months following resolution of withdrawal symptoms. 3
Additional Adjunctive Medications
For seizure prevention (alternative or adjunct): 1, 4
- Carbamazepine 200 mg every 6-8 hours can be used as an alternative to benzodiazepines
For agitation/psychosis not controlled by benzodiazepines: 1, 2
- Haloperidol 0.5-5 mg every 8-12 hours (use cautiously as adjunctive therapy only)
Supportive care includes: 4
- IV fluids and electrolyte replacement
- Comfortable, quiet environment
- Frequent vital sign monitoring
Monitoring Severity
The Clinical Institute Withdrawal Assessment for Alcohol Scale, Revised (CIWA-Ar) can guide treatment intensity: 2, 4
- Scores >8 indicate moderate AWS requiring treatment
- Scores ≥15 indicate severe AWS requiring aggressive treatment
Important caveat: Do not use CIWA protocol alone for diagnosis, as high scores occur in other conditions like sepsis, hepatic encephalopathy, anxiety disorders, and severe pain. 3, 2
Severe or Refractory Withdrawal
For patients refractory to standard benzodiazepine doses, consider ICU admission with: 7, 8
- Escalating benzodiazepine protocols
- Propofol for benzodiazepine-refractory cases
- Phenobarbital as adjunctive therapy
- Dexmedetomidine for autonomic hyperactivity
Critical Medications to AVOID
Do NOT use in patients with alcoholic liver disease: 1, 2
- Disulfiram: Potential hepatotoxicity in severe alcoholic liver disease
- Naltrexone: Risk of hepatotoxicity, not tested in cirrhosis patients
Timeline and Natural History
Withdrawal symptoms typically develop 6-24 hours after the last drink, with delirium tremens peaking at 3-5 days. 3 Monitor patients daily for up to 5 days after their last drink to verify symptom improvement and assess need for additional treatment. 5
Common Pitfalls
- Failing to administer thiamine before glucose-containing fluids 2
- Using long-acting benzodiazepines in patients with hepatic dysfunction 1
- Relying solely on CIWA scores for diagnosis rather than clinical assessment 3
- Inadequate dosing leading to progression to seizures or delirium tremens 3
- Extending benzodiazepine treatment beyond 10-14 days, risking dependence 2
