What is Delirium Tremens?

It is more than isolated hallucinations or shaking. Other withdrawal symptoms can occur without delirium, but confusion or rapid deterioration calls for emergency assessment.

Symptoms

Fluctuating confusion, agitation, tremor, sweating, fever and fast pulse may occur with hallucinations or seizures. The person may be disoriented or unable to understand events.

Causes

Abrupt cessation or a major reduction after physical dependence can produce excessive nervous-system activity. Timing varies; do not wait for a particular interval before seeking help.

Risk factors

Previous severe withdrawal or delirium, prolonged heavy use, repeated withdrawal, poor nutrition, other illnesses or sedative use increase risk.

Diagnosis

Emergency assessment checks consciousness, vital signs, alcohol and medication history, glucose, electrolytes and organ function. Infection, head injury and other delirium causes must be considered.

Treatment

Treatment involves close monitoring, clinician-adjusted withdrawal medicines, thiamine, fluid and electrolyte correction and complication management. Intensive care may be necessary; home sedative recipes are unsafe.

Complications

Seizures, cardiac instability, severe dehydration, organ injury or death can occur. Thiamine deficiency may cause additional neurological problems; early treatment reduces risk.

Prevention

If physically dependent, obtain a medical stopping plan before major abrupt changes, especially after severe previous withdrawal. Continuing care addresses alcohol-use disorder and psychological and social support.

When to see a doctor

Confusion, severe hallucinations, seizures or fever after reducing alcohol requires emergency services. Stay with the person and do not attempt treatment with alcohol or unprescribed sedatives.
