Outpatient opioid addiction treatment with sublingual buprenorphine pharmacotherapy has rapidly expanded in the United States and abroad, and, with this increase in medication availability, there have been increasing concerns about its diversion, misuse, and related harms. This narrative review defines the behaviors of diversion and misuse, examines how the pharmacology of buprenorphine alone and in combination with naloxone influence its abuse liability, and describes the epidemiological data on buprenorphine diversion and intravenous misuse, risk factors for its intravenous misuse, and the unintended consequences of misuse and diversion. Physician practices to prevent, screen for, and therapeutically respond to these behaviors, which are a form of medication nonadherence, are discussed, and gaps in knowledge are identified. ⋯ Comparisons are made with other opioids with known abuse liability and medications with no known abuse. The objective was to facilitate understanding of diversion and misuse so that all factors influencing their expression (patient and provider characteristics and public policy) can be appreciated within a framework that also recognizes the benefits of addiction treatment. With this comprehensive perspective, further careful work can help determine how to minimize these behaviors without eroding the current benefits realized through improved addiction treatment access and expansion.

This case is an amalgamation of several real patients in office-based treatment for prescription opioid dependence synthesized into a single theoretical case. The case illustrates the various ways in which medication diversion and misuse may be encountered in clinical practice and therapeutic responses designed to maximize positive treatment outcomes. It is followed by discussions from several expert addiction medicine providers from 3 different countries, giving their perspectives on the salient aspects of this case. This case conference should be of particular interest to clinicians working with opioid-dependent patients in an outpatient setting.
