Tramadol Withdrawal in the Setting of Buprenorphine Induction: A Case Report.

Initiating opioid use disorder treatment with buprenorphine conventionally requires the cessation of other opioid medications, including tramadol. Tramadol's spectrum of activity differs from most opioids, acting through serotonin and norepinephrine reuptake inhibition. Here, we report a case of 45-year-old man who experienced a complicated transition from tramadol to buprenorphine. We believe there were similarities to antidepressant discontinuation syndrome, which could be explained by tramadol's serotoninergic activity. Clinicians should be aware of these effects when discontinuing tramadol, even if replacing with another opioid. [ABSTRACT FROM AUTHOR]
