Alcohol Withdrawal Management

Primary Pharmacological Treatment

The American College of Physicians recommends benzodiazepines as the drug of choice for managing alcohol withdrawal, with long-acting agents like diazepam and chlordiazepoxide preferred for most patients due to superior seizure prevention and smoother withdrawal through self-tapering pharmacokinetics 1
Standard diazepam dosing is 5-10 mg orally, IV, or IM every 6-8 hours, with doses tapered over time 1
Chlordiazepoxide is an equally effective alternative, with a dosing regimen of 25-100 mg orally every 4-6 hours 1
Switch to lorazepam (intermediate-acting benzodiazepine) in specific high-risk populations, such as those with severe hepatic failure, advanced liver disease, advanced age, recent head trauma, respiratory failure, obesity, or other serious medical comorbidities 1, 2
Lorazepam dosing is 1-4 mg orally, IV, or IM every 4-8 hours, starting at 6-12 mg/day total, then tapered 1, 2

All patients with alcohol withdrawal must receive thiamine 100-300 mg/day to prevent Wernicke encephalopathy, maintained for 2-3 months after symptom resolution 1
Thiamine must be administered BEFORE any glucose-containing IV fluids, as glucose administration can precipitate acute thiamine deficiency and Wernicke encephalopathy 1

Admit patients with any of the following high-risk features: high levels of recent drinking, co-occurring serious medical or psychiatric illness, or failure of outpatient treatment 1, 2

Provide fluids and electrolyte replacement (especially magnesium) 1
Ensure a comfortable, reassuring environment 1
Psychiatric consultation is recommended for evaluation, acute management, and long-term abstinence planning 1, 2

Long-acting benzodiazepines like diazepam provide superior protection against seizures and delirium tremens compared to shorter-acting agents, according to the Journal of Hepatology 3

Standard dosing for diazepam is 5-10 mg orally, IV, or IM every 6-8 hours, with dose tapered over time, as recommended by Clinical and Molecular Hepatology 4

Short-acting benzodiazepines like lorazepam are traditionally considered safer in elderly patients and those with hepatic dysfunction, as noted by the Journal of Hepatology 3
Benzodiazepines should not be continued beyond 10-14 days due to abuse potential, especially in patients with alcohol use disorder, according to the Journal of Hepatology 3

Thiamine 100-300 mg/day should be administered before any glucose-containing IV fluids to prevent Wernicke encephalopathy, as recommended by Clinical and Molecular Hepatology 4

The CIWA-Ar score should be used to guide treatment intensity, with a score >8 indicating moderate AWS requiring pharmacological treatment, and a score ≥15 indicating severe AWS, according to the Journal of Hepatology 3
