Xylazine

Xylazine is a veterinary sedative and pain reliever, FDA approved for large mammals (not approved for humans). Xylazine is prevalent in the opioid supply on the East coast and has been reported anecdotally in the opioid supply in the Portland area. Xylazine is not being added to any drug aside from opioids.

Xylazine is not an opioid so it does not respond to naloxone. However it is most commonly mixed with opioids that will respond to naloxone so always administer naloxone if someone has symptoms of an opioid overdose.
