High-Dose Buprenorphine Initiation: A Scoping Review
Objective
The aim of the study is to review and synthesize the literature on high-dose buprenorphine initiation (>12-mg total dose on day of initiation).
Methods
A scoping review of literature about high-dose buprenorphine initiation was conducted. MEDLINE, Embase, PsycINFO, and Cochrane Central were searched. Randomized controlled trials, prospective and retrospective cohort studies, and case studies/reports published in English before February 13, 2023, were included.
Results
Fifteen studies reporting outcomes from 580 high-dose buprenorphine initiations were included. Eight studies were in inpatient settings, 3 in emergency departments, 3 in outpatient settings, and 1 in a first-responder setting. Four studies reported high-dose initiations among individuals exposed to fentanyl. There were no reported events of fatal or nonfatal overdose or respiratory depression, although adverse event reporting was inconsistent in published reports. The most reported side effects with high-dose buprenorphine initiation were nausea or vomiting (n = 17) and precipitated withdrawal (n = 7). The most serious reported adverse event was hypotension requiring oral hydration (n = 2). Most studies reported improvements in subjective or objective withdrawal symptoms. The duration of follow-up ranged from none to 8 months.
Conclusions
High-dose buprenorphine initiation has not been associated with reported cases of overdose or respiratory depression. However, the current literature about high-dose buprenorphine is limited by inconsistent side effect reporting, limited power to detect rare safety events such as respiratory depression, limited follow-up data, and few comparison studies between high-dose and regular initiation protocols. Further prospective data are needed to evaluate the safety and effectiveness of this initiation strategy.
