Maine Faces New Drug Threat as Vet Sedative Medetomidine Surfaces in Street Drugs

Maine public health officials warn medetomidine, a veterinary sedative nicknamed 'rhino tranq,' has appeared in the state's drug supply—often mixed with fentanyl—and is far more potent than xylazine. It can trigger severe withdrawal and dangerous drops in blood pressure or heart rate; naloxone may not reverse medetomidine on its own, so prompt medical care is essential. Testing is limited, and harm-reduction groups are urging drug checking and awareness as Bangor and Penobscot County report rising overdoses amid an HIV outbreak among people who use drugs.
