When should the prescribing cascade be used?

• A. When there is no authorised GB or UK product for the condition.
• B. Only in emergency cases.
• C. Only for off-label use within standard guidelines.
• D. After veterinary approval is granted.

Answer: (A)

The prescribing cascade is used when there is no authorised GB/UK product for the animal’s condition. In that situation, the veterinarian can provide treatment by using medicines not licensed for that species or condition, or for an unapproved indication, following a documented justification and ensuring appropriate safety monitoring. This approach is about ensuring the animal isn’t left untreated when licensed options don’t exist, within the regulatory framework and with the vet’s professional oversight. It isn’t limited to emergencies, nor is it only for off-label use within guidelines; those scenarios can be part of the cascade, but the trigger is the absence of a suitable licensed product for the condition.
