Management of Alcohol Withdrawal Syndrome

Initial Assessment and Diagnosis

Evaluate for signs and symptoms of alcohol withdrawal syndrome (AWS), which typically develops within 6-24 hours after the last drink, using the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) score to assess severity of withdrawal 1
Monitor for symptoms including increased blood pressure, elevated pulse rate, tremors, hyperreflexia, irritability, anxiety, headache, nausea, and vomiting 2
A CIWA-Ar score >8 indicates moderate AWS, while a score ≥15 indicates severe AWS 1

Benzodiazepines are first-line treatment for moderate to severe AWS, with long-acting benzodiazepines (diazepam, chlordiazepoxide) providing better protection against seizures and delirium, and short and intermediate-acting benzodiazepines (lorazepam, oxazepam) being safer in patients with hepatic dysfunction 1, 2
Use a symptom-triggered regimen rather than fixed-dose schedule to prevent drug accumulation, and limit benzodiazepine use to 7-10 days to avoid potential for abuse 1, 3

Acamprosate reduces withdrawal effects and alcohol craving, and should be started 3-7 days after last alcohol consumption, after withdrawal symptoms resolve, with a dosage of 1,998 mg/day for patients ≥60 kg, and a treatment period of 3-6 months 4
Naltrexone decreases excessive drinking and recurrence rates, with a dosage of 25 mg for first 1-3 days, then increase to 50 mg daily, and a treatment period of 3-12 months, but is not recommended in patients with alcoholic liver disease due to risk of hepatotoxicity 4
Baclofen shows promise for increasing abstinence rates and preventing relapse, with the French ANSM recommending not exceeding 80 mg/day 3
Topiramate demonstrates efficacy in reducing heavy drinking, and is associated with decreased liver enzyme levels 3
Disulfiram is not commonly used due to potential hepatotoxicity in patients with liver disease 4, 5

Individual psychotherapy helps establish a therapeutic plan, with treatment principles including helping patient accept lack of control over alcohol, providing education regarding alcohol dependence, and helping patient achieve self-control to maintain abstinence 4
Group therapy such as Alcoholics Anonymous provides peer support, while family education and therapy address dysfunctional family dynamics 4
Cognitive behavioral therapy, social skills training, and coping skills training are also effective, as are brief interventions including motivational interviewing 4, 6

Evaluate for psychiatric comorbidities (anxiety disorders, affective disorders, schizophrenia) and screen for other substance use disorders, including nicotine dependence 7
Coordinate care between hepatologists and addiction specialists (psychiatrists, psychologists, social workers) 7
Failing to recognize progression to severe forms of AWS (delirium tremens, seizures) is a common pitfall to avoid 1

The American Association for the Study of Liver Diseases recommends that benzodiazepines should be started within 6-24 hours after the last drink when alcohol withdrawal symptoms typically develop, including tremors, elevated blood pressure and pulse, anxiety, nausea, and vomiting 8, 9
The American College of Gastroenterology suggests that lorazepam 1-4 mg orally or IV/IM every 4-8 hours should be initiated immediately upon presentation with withdrawal symptoms, not delayed 9
The Clinical and Molecular Hepatology guidelines indicate that lorazepam is specifically recommended for patients with hepatic dysfunction or elderly patients because it has a shorter half-life and safer metabolism compared to long-acting agents like diazepam or chlordiazepoxide 8, 9

The Clinical and Molecular Hepatology guidelines recommend that thiamine 100-300 mg/day must be administered BEFORE any glucose-containing IV fluids to prevent precipitating acute Wernicke encephalopathy, starting immediately at presentation 9
