French National Guidelines for the Appropriate Use of Opioids: Analgesia, Opioid Use Disorder, and Overdose Prevention-Part 2: Prevention and Management of Opioid Use Disorder and Overdose.

Opioid use disorder (OUD) and overdoses represent critical challenges linked to the widespread availability of opioid medications. To address these risks, the French National Authority for Health convened a multidisciplinary working group to develop comprehensive guidelines on the prevention and management of OUD and overdoses. These recommendations expand on the second part of the guidelines, which specifically addressed the prevention and management of OUD and overdoses. Grounded in the highest level of international evidence and developed through a rigorous formal consensus process, the guidelines emphasize appropriate opioid prescribing as the cornerstone of prevention. They provide practical recommendations for identifying patients at risk, detecting problematic use early, and initiating opioid agonist treatment when indicated. The role of naloxone as an essential tool to prevent fatal overdoses is highlighted, along with strategies for coordinated and multidisciplinary care across diverse healthcare settings. By integrating prevention, treatment, and harm reduction measures, these guidelines seek to balance legitimate access to opioid analgesics with robust safeguards against opioid use disorder and overdose. Although developed within the French healthcare system, their strong evidence base and underlying clinical principles make them applicable to international practice. Together with the first part on pain management, they constitute one of the most comprehensive and up-to-date sets of recommendations on the safe and effective use of opioid medications.
