Which combination of medications is commonly used to treat alcohol withdrawal in the emergency department?

• A. Thiamine Alone
• B. Librium and Ativan
• C. Flumazenil and Diazepam
• D. Naloxone and Haloperidol

Answer: (B)

Alcohol withdrawal is a hyperexcitable state driven by reduced GABA activity and increased excitatory activity after stopping alcohol. In the emergency department, the treatment focus is to calm the CNS and prevent complications like seizures and delirium tremens, which is achieved with benzodiazepines. Using a long-acting agent such as chlordiazepoxide (Librium) provides steady baseline coverage, while a shorter-acting agent like lorazepam (Ativan) can be used to quickly control breakthrough agitation and autonomic symptoms and to tailor dosing as withdrawal evolves. This combination allows effective suppression of withdrawal symptoms with the flexibility to adjust doses and taper as the patient improves, which is especially helpful in severe cases or when hepatic function is a concern.

Thiamine supplementation is essential in alcohol withdrawal management to prevent Wernicke’s encephalopathy; it’s typically given early, with glucose withheld until thiamine is administered if needed, because thiamine deficiency is common in chronic alcohol use and can worsen with dextrose infusion.

Other options don’t fit as well: giving thiamine alone doesn’t treat withdrawal symptoms; flumazenil would block benzodiazepines and can precipitate withdrawal seizures in someone who is benzodiazepine-dependent or in active alcohol withdrawal; naloxone addresses opioid overdose, not alcohol withdrawal; haloperidol may help with agitation but does not treat the underlying withdrawal trajectory and can miss the risk of seizures or delirium tremens if used alone.
