Over the next 18 months, the last antimicrobials licensed for animal use over-the-counter will be relabeled to require a veterinarian’s prescription.  University of Missouri Extension veterinarian Craig Payne says that for producers to continue to purchase these medications, they will need to start working with a veterinarian.

Payne elaborates on what would typically constitute a veterinary patient/client relationship.

MU Extension veterinarian Craig Payne says common animal medications that will require a prescription by June 2023 include Lincomycin, LA-200, Noromycin 300, and injectable penicillin.
