Which of the following statements best describes the purpose of the prescribing cascade?

• A. To ensure all medicines are licensed for veterinary use.
• B. To standardize dosing intervals across species.
• C. To prevent animal suffering by allowing appropriate use of non-licensed medicines when no licensed alternative exists.
• D. To maximize profits for the practice.

Answer: (C)

The prescribing cascade exists to safeguard animal welfare by allowing the use of medicines that aren’t licensed for a specific species or condition when there is no licensed alternative. This means a veterinarian can provide timely and appropriate treatment rather than withholding care, but only with valid justification, correct dosing, and careful monitoring. The aim is humane, safe care within regulatory safeguards, not to ensure every product is licensed, to standardize dosing across species, or to boost profits. For example, if no licensed veterinary analgesic is suitable, a non-licensed medicine may be used with appropriate justification and oversight to relieve suffering.
