August 23, 2023 – Xylazine has emerged as an adulterating agent in many illicit drug products and can have significant adverse effects, including death. It is a non-opioid sedative and muscle relaxant used in veterinary medicine. The United States FDA has not approved xylazine for human use, and it is not federally classified as a controlled substance at this time.
- In April, the White House officially designated fentanyl adulterated or associated with xylazine as an emerging threat to the United States.1
- In March, the US Drug Enforcement Administration issued an alert about the widespread threat of fentanyl mixed with xylazine.2
- In March, the Substance Abuse and Mental Health Services Administration (SAMHSA) released a letter alerting providers and grantees to the risks of xylazine.3
