Piloting a Hospital-Based Rapid Methadone Initiation Protocol for Fentanyl 

Journal of Addiction Medicine

The epidemic of fentanyl has led to increased opioid tolerance and made traditional dosing for methadone initiation insufficient. In this study, the authors examine an inpatient rapid titration of methadone initiation among patients with opioid use disorder (OUD). The protocol recommended dosing of 60 mg on day 1, 70 mg day 2, 80 mg day 3 and 100 mg day 4-7. After patients with significant underlying medical conditions, benzodiazepine or alcohol use and age >65 were excluded, 25 patients underwent the rapid initiation. No patients in the study experienced an adverse event and while additional research is needed, the study demonstrated the feasibility of rapid initiation of methadone for OUD in select patients in an inpatient setting.
