Diazepam and chlordiazepoxide are common, due to their long half-life. There is no role for anticonvulsants.Antipsychotics such as haloperidol should be avoided because they can lower the seizure threshold and cause prolonged QT interval.Hydrate with isotonic fluids and electrolyte replacement. Symptom-triggered therapy is recommended. A work-up for alternative diagnosis is also very important.Use only lorazepam or oxazepam for cirrhosisCT head to look for intracranial bleedLumbar puncture to rule out meningitis if there is a feverChest x-ray: Look for aspiration pneumoniaHigh doses of thiamine IV for Wernicke and Korsakoff. Treatment for alcoholic hallucinosis is benzodiazepines and haloperidol (there is no risk of seizures, so it can be used here).
