Treatment of Delirium Tremens

Pharmacological Management

Benzodiazepines are the gold standard first-line treatment for delirium tremens, with diazepam or lorazepam as preferred agents, administered intravenously in escalating doses until symptom control is achieved, as recommended by the American Association for the Study of Liver Diseases 1
The use of short-acting benzodiazepines, such as lorazepam, is preferred in elderly patients and those with advanced liver disease to reduce accumulation risk, according to the American Association for the Study of Liver Diseases 1
Haloperidol may be used for psychotic symptoms, such as hallucinations or severe agitation, that persist despite benzodiazepine therapy, with a dosing of 0.5-2 mg IV slow bolus initially, as suggested by the World Journal of Emergency Surgery and the American College of Emergency Physicians 2

Correction of imbalances, such as dehydration, hypo/hyperglycemia, and electrolyte disturbances, is crucial as these can worsen delirium, as stated by the World Journal of Emergency Surgery and the Society of Critical Care Medicine 2, 3

Consideration of relapse prevention medications, such as acamprosate or naltrexone, after the acute withdrawal phase, is recommended, although not useful during active withdrawal, as suggested by the American Association for the Study of Liver Diseases and the National Institute on Alcohol Abuse and Alcoholism 1
Disulfiram should be avoided in patients with liver disease due to hepatotoxicity risk, as warned by the American Association for the Study of Liver Diseases and the National Institute of Diabetes and Digestive and Kidney Diseases 1

The Critical Care Medicine guidelines recommend against routine use of haloperidol or atypical antipsychotics for treating delirium, as they do not shorten delirium duration or improve mortality, but short-term use is warranted for patients with significant distress from hallucinations or delusion-associated fearfulness 4
Discontinue antipsychotics immediately once distressful symptoms resolve, as recommended by the Critical Care Medicine guidelines 4
Dexmedetomidine may help when agitation precludes weaning from mechanical ventilation, according to the Critical Care Medicine guidelines 4

Multicomponent strategies, including providing a quiet room, displaying visible calendars and clocks, and maintaining caregiver consistency, have been shown to reduce delirium duration, ICU length of stay, and hospital mortality, as reported in the Critical Care Medicine journal 4
