Is Xylazine legal in Mexico?

Confirmed against a primary sourceVerified July 14, 2026
Legal status
Xylazine (xilacina) is regulated in Mexico as a veterinary medicine restricted to use by veterinarians: it is a registered veterinary sedative/analgesic and is not listed as an estupefaciente or psicotrópico under the Ley General de Salud human controlled-substances tables.
Consequences if caught
Diversion of xilacina is addressed as a health-regulation / veterinary-medicines matter; Mexican authorities have issued border-city alerts over its illicit use as an adulterant, but it is not a controlled human drug.
If prescribed or medical
Administered exclusively by a veterinarian for sedation/analgesia in cattle, equines, dogs and cats (and not in equines destined for human consumption); xylazine has no human indication.
Documentation
Xylazine veterinary products (e.g. Xilazina 20 mg/ml injectable) are marketed for veterinary use; Mexican government advisories describe xilacina as a veterinary drug administered only by veterinarians.
