Livestock Antibiotics will require a Veterinary Prescription starting June 11th

Most over-the-counter livestock antibiotic medications will no longer be available for purchase without a veterinary prescription starting June 11th.

"This will end over-the-counter sales of antibiotics, and livestock owners will need a prescription from a veterinarian if they want to continue to have access," says Craig Payne, veterinarian, University of Missouri Extension.

The final phase of the regulation addresses several over-the-counter antibiotics and must display the following language on their RX labels:

"Caution: Federal law restricts this drug to use by or on the order of a licensed veterinarian."
