Use of intravenous buprenorphine microdosing to initiate medication for opioid use disorder in a patient with co-occurring pain: case report.

Introduction: Buprenorphine is used to treat opioid use disorder (OUD). However, therapy is often disrupted during acute pain episodes, and re-initiation is often deferred due to intolerable interruption in opioid analgesics. This case report describes a unique strategy for inducing buprenorphine without stopping opioid analgesics.

Case: One patient with OUD and acute pain was initiated on buprenorphine using intravenous microdosing without precipitated withdrawal or pain exacerbation. Full agonist opioids were successfully weaned after discharge and the patient was linked with a community-based treatment program.

Conclusion: This case describes use of intravenous buprenorphine to treat OUD and acute pain without adverse consequences.
