Which detail must be included on the dispensing label for a veterinary prescription under the veterinary cascade?

• A. The words 'for animal treatment only'
• B. The date of manufacture
• C. The name of the veterinarian
• D. The dosage in mg per kg

Answer: (A)

When medicines are used under the veterinary cascade, clear labeling is essential to prevent misuse and protect people as well as animals. The one detail that must appear on the dispensing label is the explicit note that the product is “for animal treatment only.” This statement serves as a strong safety reminder that the medicine is intended for animal use and should not be given to humans or used outside veterinary care, which is especially important when using medicines off-label under the cascade.

Other information such as the date of manufacture, the veterinarian’s name, or the dosage expressed as mg per kg may be relevant in some contexts, but they are not the mandatory safety cue the cascade requires in the same way. The crucial point is to make it unequivocally clear that the product is for animal treatment only, to support appropriate and safe use.
