Swine water medications transitioning from over-the-counter (OTC) to prescription (Rx) 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 water soluble medications transitioning from OTC to Rx status

Upon completion of their voluntary transition from OTC to Rx, all uses of the following medications will require a prescription from a veterinarian as of January 1, 2017.

Established drug name Examples of trade name(s)
Chlortetracycline Aureomycin®, Chloronex, Chlortetracycline, Chlortetracycline Bisulfate, Chlortet-Soluble-O, Fermycin, Pennchlor™
Gentamicin Garacin®, GenGard®, GentaMed™, Gentocin®, Gentoral®
Lincomycin Linco, Lincomix®, Lincomycin, Lincomycin Hydrochloride, Lincosol, LincoMed
Neomycin Biosol®, Neo, NeoMed®, Neomycin, Neomycin liquid, Neomycin Sulfate, Neomix®, Neo-Sol®, Neosol-Oral
Oxytetracycline Agrimycin™, Oxy-Tet™, Oxytet®, Oxytetracycline HCL, Terramycin®, Tetroxy®, Tetroxy® HCA
Sulfamethazine SMZ-Med™, Sulmet®, Purina® Sulfa
Tetracycline Duramycin, Polyotic®, Tetra-Bac, Tetracycline, Tetracycline hydrochloride, TetraMed®, Tet-Sol®, Tetrasol

Note: Apramycin, carbomycin/oxytetracycline*, Chlortetracycline/sulfamethazine*, streptomycin, sulfachloropyrazine, sulfachloropyridazine, and sulfamerazine/sulfamethazine/sulfaquinoxaline* are expected to transition to Rx status, but are not marketed at this time. If they return to the market after January 1, 2017, they will require a prescription from a veterinarian.

What does "medically important" mean?

An antibiotic is considered medically important if it is used, or antibiotics in the same family of medications, is used in human or animal medicine.
