What term describes medicines prescribed under the cascade?

• A. Prescribed under the cascade
• B. Licensed medicines
• C. Over-the-counter medicines
• D. Off-licence

Answer: (A)

Medicines prescribed under the cascade are those used under a regulated framework that allows alternatives when no suitable licensed veterinary product is available. This term specifically describes how the medicine is chosen and authorized for use in the animal under the cascade, rather than being a standard licensed product for that species or indication. The cascade ensures appropriate treatment while requiring justification, proper record-keeping, and adherence to withdrawal times.

In this system, you might use a medicine licensed for another species or indication, or a human medicine, but the description that applies to its status is that it is prescribed under the cascade. This distinguishes it from medicines that are simply licensed for the target species, or from over-the-counter products, or from off-label use outside the cascade framework.
