Veterinary Sedative Found in Utah Street Drugs Unresponsive to Narcan

According to the Utah Department of Public Safety, state opioid and fentanyl task forces have identified medetomidine—a potent veterinary sedative—in the local illicit drug supply, creating new risks for overdose responders because the substance cannot be reversed by naloxone.

Understanding Medetomidine in the Illicit Drug Supply

First detected in street drugs across the United States in 2022, medetomidine has been linked to a spike in dangerous overdoses, according to state public safety officials. The substance is a veterinary sedative that is more potent than xylazine, another veterinary sedative. Because medetomidine is not an opioid, standard reversal agents like naloxone, commonly known as Narcan, do not reverse its specific effects on the human body, the Utah Department of Public Safety reported.

Why Naloxone Remains Essential During Overdoses

Even though naloxone does not counteract medetomidine, state officials stress that carrying and administering the spray remains critical. According to the Utah Department of Public Safety, medetomidine is frequently mixed with fentanyl and other opioids. “Because it is often mixed with fentanyl and other opioids, naloxone remains essential to every overdose response,” the department stated. Timely detection by state task forces allows public health partners to issue rapid guidance and highlights the ongoing need for surveillance and community education.

Recommended Steps for Suspected Overdose Response

When encountering a suspected overdose involving emerging contaminants, public safety guidelines emphasize a straightforward, reliable sequence of emergency actions. The Utah Department of Public Safety provided the following instructions for bystanders:

• Call 911 immediately to dispatch emergency medical services.
• Administer naloxone to reverse potential opioids like fentanyl, nitazenes, heroin, and morphine that may be present alongside sedatives.
• Focus on breathing rather than wakefulness; look for improved breathing patterns.
• Give rescue breaths if the individual is not breathing adequately.
• Use the recovery position if they breathe on their own while waiting for EMS.
• Continue monitoring the patient and administer additional naloxone if breathing slows or stops again.

“Medetomidine is another change in the drug supply, but the response is unchanged: call 911, administer naloxone, support breathing, and stay with the person until help arrives,” state officials emphasized, noting that these steps remain the most effective way to save lives.

Frequently Asked Questions

What is medetomidine?

Medetomidine is a veterinary sedative that has been detected in the illicit drug supply and is more potent than xylazine.

Does Narcan reverse medetomidine?

However, it remains vital because medetomidine is frequently mixed with fentanyl and other opioids.

What should I do if I suspect an opioid and sedative overdose?

Call 911 immediately, administer naloxone, monitor and support the person’s breathing, provide rescue breaths if necessary, and stay with them until medical help arrives.
