Swine feed medications transitioning from over-the-counter (OTC) to veterinary feed directive (VFD) status

Sarah Schieck

On January 1, 2017, the U.S Food and Drug Administration's (FDA) new regulation addressing on-farm antibiotic use in food-animal production will take effect. The purpose of this publication is to identify which swine medications will be affected by these changes. FDA's effort is aimed to eliminate the use of medically important (to human illness) antibiotics for growth promotion purposes in food-animal production and to bring therapeutic use of antibiotics in feed and water - to treat, control, or prevent specific disease - under additional veterinary oversight. The new requirements will affect producers, veterinarians, feed mills and suppliers.

Swine medications transitioning from OTC to VFD

Starting January 1, 2017, all feed uses of the following medications approved for swine use, alone and in combination with other medications, will require a VFD.

Established drug name Examples of trade name(s)$
Chlortetracycline (CTC) Aureomycin®, Chlorachel™, Chloratet, ChlorMax™, CLTC, CTC®, Deracin®, Pennchlor®, Pfichlor™
Chlortetracycline/sulfamethazine Aureomix® S
