Antibiotics Changing from Over the Counter (OTC) to Prescription (Rx)

In June 2021, the FDA announced that all medically important antibiotics currently available over the counter (OTC) will transition to prescription (Rx) status within the next two years (GFI 263). This change is part of a long-term plan to decrease antibiotic resistance by moving all medically important antibiotics under veterinary supervision. The label changes must occur by June 11, 2023, but some products may become prescription before then as manufacturers proactively update their labels.

Once the change is fully implemented, antibiotics can be purchased through a veterinary clinic, veterinary pharmacy or distributor as long as a veterinarian provides a prescription to that supplier. To prepare, farmers need a valid veterinary client patient relationship
(VCPR). While it is not necessary for a veterinarian to personally examine every animal, the veterinarian must visit the farm and be aware of animal management before writing a prescription.

For advice on how to manage your herd through this transition, contact us. Our sales, veterinary and pharmacy teams are here to help
