Alcohol-induced delirium tremens typically begins roughly how long after the last drink?

• A. About 3 days
• B. Immediate upon cessation
• C. About 18 hours
• D. About 1 week

Answer: (C)

Delirium tremens is the most severe form of alcohol withdrawal, and its timing reflects when brain and autonomic systems rebound after the last drink. It typically begins about 48 to 72 hours after cessation, not immediately and not after a full week. Early withdrawal signs, such as tremors and agitation, can appear within hours, and seizures may occur around the first couple of days, but delirium tremens usually emerges during the second to third day. Understanding this window helps distinguish DTs from milder withdrawal and guides urgent management, since DTs can be life-threatening and require IV benzodiazepines, careful monitoring, electrolyte correction, and thiamine.
