Case Studies In Toxicology: Withdrawal: Another Danger of Diversion

There are, however, limitations to this approach. Namely, some BZDs are only available in oral formulations (eg, alprazolam and clonazepam) or the BZD of choice may not be readily available or on formulary within a given institution. In a patient with a severe withdrawal syndrome where it is not feasible or potentially harmful to administer an oral medication, it is reasonable to provide parenteral (preferably intravenous [IV]) BZD therapy. The optimal approach is to start with a small “standard” dose and titrate to effect while monitoring for adverse effects (eg, oversedation, ventilatory depression). Redosing should be triggered by symptoms or signs, and not performed in a timed or standing-order fashion. If this approach proves ineffective and withdrawal symptoms persist despite adequate BZD therapy, a direct GABA agonist such as propofol is a sensible alternative or adjuvant treatment. This may sound similar to the management of patients with ethanol withdrawal; indeed, this approach is essentially the same, with the exception of the more drawn-out time course.

Case Conclusion

After arrival in the ED, the patient received diazepam 10 mg IV and was subsequently admitted to the hospital for further evaluation. During his hospitalization, the patient was re-started on his usual dose of oral alprazolam. No further withdrawal syndrome was observed, and he was discharged on hospital day 2 with a plan to slowly taper his alprazolam dose with his outpatient psychiatrist.
