Which regulatory agencies oversee NexGard (oral flea and tick product) and K9 Advantix II (topical) for dogs respectively?

• A. FDA, EPA
• B. FDA, USDA
• C. EPA, FDA
• D. EPA, USDA

Answer: (A)

Regulatory oversight divides between veterinary drugs and pesticides used on animals. NexGard is an oral flea and tick medication for dogs treated as a veterinary drug, so it falls under the U.S. Food and Drug Administration’s Center for Veterinary Medicine, which reviews safety, efficacy, and labeling under the FD&C Act for animal drugs. K9 Advantix II is a topical pesticide product used on dogs, so it’s regulated by the U.S. Environmental Protection Agency under FIFRA, with registration and labeling addressing how it should be used and its safety for pets and people. So the correct pairing is FDA for NexGard and EPA for K9 Advantix II.
