Which two medications are commonly used to treat alcohol withdrawal in the emergency department?

• A. Thiamine
• B. Librium and Ativan
• C. Haloperidol
• D. Ondansetron

Answer: (B)

Alcohol withdrawal symptoms stem from a sudden drop in CNS inhibition, so the treatment goal is to rapidly enhance GABAergic activity to calm the brain. Benzodiazepines act on the GABA-A receptor to suppress excitation, prevent seizures, and ease tremors and agitation. In the emergency department, chlordiazepoxide (Librium) and lorazepam (Ativan) are the classic choices because they are effective, titratable, and readily available. Librium’s long action helps provide smooth control and easier tapering, while lorazepam is shorter-acting with no active metabolites, making it safer in patients with liver disease and easier to adjust dose based on withdrawal severity. They can be given IV for quick effect and then switched to oral as the patient stabilizes, often guided by a withdrawal scale like CIWA-Ar. Thiamine is essential in alcohol users to prevent Wernicke’s encephalopathy, but it does not treat withdrawal symptoms itself. Other drugs, like haloperidol or ondansetron, address agitation or nausea but do not address the underlying withdrawal physiology as effectively as benzodiazepines.
