Illicit use of the veterinary tranquilizer xylazine continues to spread across the United States. The drug, which is increasingly mixed with fentanyl, often fails to respond to the opioid overdose reversal medication naloxone and can cause severe necrotic lesions.
A report released by Millennium Health, a specialty lab that provides medication monitoring for pain management, drug treatment, and behavioral and substance use disorder treatment centers across the country, showed the number of urine specimens collected and tested at the US drug treatment centers were positive for xylazine in the most recent 6 months.
As previously reported by Medscape Medical News, in late 2022, the US Food and Drug Administration (FDA) issued a communication alerting clinicians about the special management required for opioid overdoses tainted with xylazine, which is also known as "tranq" or "tranq dope."
