Delirium tremens (DTs) is a severe form of alcohol withdrawal that can occur after a person stops drinking following a period of prolonged or heavy alcohol use.12

The condition typically develops after 36 hours of abstinence. It is often preceded by earlier withdrawal symptoms—such as tremulousness, sweating, restlessness, sleep disturbances, and seizures—which commonly manifest within the first 48 hours.2

The development of delirium tremens is influenced by several factors, including the individual's overall health, the quality of care and treatment received during withdrawal, and the presence of any concurrent diseases. The condition is frequently complicated by exhaustion, dehydration, and a lack of proper nutrition. When it occurs, it is characterized by gross trembling of the entire body, fever, and frank delirium, often accompanied by disorientation and hallucinations. Because delirium tremens carries a significant risk of mortality if left untreated, it is a medical emergency that requires professional clinical intervention.21
