In what instance must a drug label specifically include "For veterinary use only"?

The label "For veterinary use only" must be included on all medications dispensed to pets to clearly indicate that the product is intended specifically for animals and not for human use. This distinction helps ensure that pet owners are aware that the medication has been formulated and approved specifically for veterinary purposes, which may differ significantly from human medications in terms of dosage, formulation, and potential side effects. By stating "For veterinary use only," it also serves as a reminder of the importance of following veterinary guidance regarding the use of the medication, thus promoting safety and efficacy in animal care.

In contrast, not all over-the-counter medications or prescription medications require such labeling if they are also approved for human use or are intended for a broader range of applications. Controlled substances have their own specific regulations and may not necessarily include the "For veterinary use only" statement unless they are exclusively used in veterinary practice. Thus, identifying medications explicitly designated for animal use is vital in veterinary medicine.
