What is the Cascade System?

The cascade is a regulatory framework established under EU Regulation 2019/6 that allows veterinarians to prescribe unauthorized medicines in exceptional circumstances to prevent unnecessary animal suffering.

When Can the Cascade Be Applied?

The cascade may only be used when:

  • No authorized veterinary medicine is available for the specific condition
  • Treatment is necessary to avoid unacceptable animal suffering
  • The veterinarian takes full professional responsibility for the decision

Cascade for Food-Producing Animals (Article 113)
