Alcohol withdrawal

Alcohol withdrawal is caused by the abrupt cessation of alcohol consumption in patients with alcohol dependence or chronic alcoholism.

The clinical presentation consists of a spectrum of signs and symptoms, including autonomic hyperactivity, tremulousness, restlessness, seizures, and potentially life-threatening alcohol withdrawal delirium.

Alcohol withdrawal syndrome is a clinical diagnosis.

Symptom-triggered therapy with benzodiazepines remains the cornerstone of management.

Alcohol withdrawal syndrome (AWS), commonly referred to as "the shakes," occurs in patients with alcohol dependence when their daily alcohol consumption is decreased or stopped. The decrease in blood ethanol below the level at which the patient is habituated triggers AWS. Symptoms typically begin 6-24 hours after the patient's last drink, and may progress to potentially life-threatening alcohol withdrawal delirium (also referred to as delirium tremens), with or without seizures.[1]Bayard M, McIntyre J, Hill KR, et al.
