Abstract
Medetomidine, a potent central acting α2 agonist, has emerged as a fentanyl adulterant in the non-medical opioid supply. Its use has been linked to a novel withdrawal syndrome that is often resistant to conventional treatment protocols. Four cases are presented exemplifying extreme, but increasingly common forms of this withdrawal syndrome. A literature review is provided demonstrating both the paucity of available literature as well as potential avenues for treatment and future research. As adulterants continue to proliferate in the illicit drug supply, clinicians should anticipate atypical withdrawal phenotypes and consider early intervention.
