Opioid-Induced Hyperalgesia in a Cancer Patient on High-Dose Methadone Maintenance Therapy: A Case for Subspecialty Opioid Use Disorder Primary Care

Summary: | As opioid use disorder (OUD) reaches epidemic levels in the United States, medication-assisted treatment (MAT) plays a central role in its treatment. Methadone, a long-acting mu-opioid receptor agonist has been shown to be effective in managing OUD. It is also known that chronic opioid therapy may have the paradoxical effect of increased sensitivity to pain, a phenomenon called opioid-induced hyperalgesia (OIH). This presents a conundrum when a patient such as ours, on MAT presents with acute pain and OIH. This case report illustrates the current challenges health care providers encounter when treating patients on chronic MAT for non-opioid-related conditions. As this patient population ages, these encounters will become more common. These patients will need appropriate health care screening and chronic care management. This case serves two purposes; to highlight the difficulty in treating acute pain in patients on long-term high-dose methadone coupled with the missed opportunity for primary care for OUD patient population, and proposes that education reforms in this area be implemented now. |
