Is extra-label use of veterinary feed directive (VFD) drugs allowed under certain circumstances?

• A. True
• B. False
• C. Only with special approval
• D. Only for certain species

Answer: (B)

Extra-label use of VFD drugs is not allowed. The Veterinary Feed Directive requires these drug products to be used in feed only under the veterinarian’s written authorization and exactly as specified on the VFD—specifying the drug, the target species, the indication, the dosage, duration, and administration. There is no provision for off-label use of VFD drugs. If a different species, indication, or dosing is needed, a new VFD aligned with that use must be issued, or a non-VFD drug or other approved therapy should be used. (Note: extra-label use provisions under ADUCA apply to drugs outside the VFD framework, not to VFD drugs in feed.)
