Objective: To discuss the phenomenon of opioid induced hyperalgesia (OIH) and investigate the data and clinical recommendations available on this topic.
Design: A literature search on the topic of OIH was performed. Relevant studies pertaining to OIH were included in this review.
Results: Existing studies and reviews on the pathophysiology, diagnosis, and clinical management of OIH are discussed with updated data and literature references.
Conclusion: As more opioids are prescribed, especially to treat chronic nonmalignant pain, OIH becomes more of a relevant and significant issue. Although the exact mechanisms of OIH are not clearly understood further research is required to broaden and develop our knowledge of this topic.
