Should we do symptom-triggered or fixed dosing of benzodiazepines?
Saitz et al. Individualized Treatment for Alcohol Withdrawal: A Randomized Double-blind Controlled Trial
To assess the effect of an individualized treatment regimen on the intensity and duration of medication treatment for alcohol withdrawal.
A randomized double-blind, controlled trial
An inpatient detoxification unit in a Veterans Affairs medical center.
Fixed-schedule: Chlordiazepoxide four times daily +PRNs vs Symptom triggered therapy: Chlordiazepoxide only in response to signs and symptoms of alcohol withdrawal
The median duration of treatment in fixed-schedule 68 hr vs 9 hr in symptom-triggered group (P<.001)Mean dose 425 mg vs 100 mg (P<.001)No significant differences in the severity of withdrawal, the incidence of seizures, or delirium tremens.
Symptom-triggered therapy individualizes treatment, decreases both treatment duration and the amount of benzodiazepine used, and is as efficacious as standard fixed-schedule therapy for alcohol withdrawal.
