Health departments in the Midwest are issuing warnings about a new deadly animal tranquilizer called medetomidine that has been linked to overdose deaths.
Medetomidine is a powerful sedative used in veterinary medicine to keep animals sedated during exams and medical procedures. It was approved by the U.S. Food and Drug Administration (FDA) for this use in 2022.
However, the drug has been found to be deadly when mixed with other substances, such as fentanyl or heroin, which are often used illicitly.
According to reports from Michigan and Indiana health departments, at least three people have died from overdoses involving medetomidine since March 2024. The drug is most commonly detected alongside these other substances.
Medetomidine causes a decrease in heart rate, increasing the chance of developing an irregular heartbeat. It cannot be reversed by naloxone or Narcan, which have been used to reverse overdoses for other drugs.
The Michigan Department of Health and Human Services and Indiana Department of Health are urging awareness and distribution of drug test strips to help identify the presence of medetomidine in illicit substances.
Health departments in Philadelphia, Pittsburgh, and Chicago have also reported outbreaks of overdoses involving medetomidine.
It is important for individuals who use drugs and their loved ones to be aware of this new and dangerous drug. If an overdose is suspected, naloxone should still be administered as it may help reverse the effects of other substances present in the illicit substance.
