Effective next week, and as reported in Dairy Herd Management, FDA's "Guidance for Industry #263" goes into effect. This will require that certain listed antibiotics (and other therapeutics) can only be purchased from a licensed pharmacy via a valid veterinary-client-patient relationship (VCPR) and not over the counter (OTC). Livestock farmers can buy the antibiotics wherever they are sold (not necessarily from the prescribing veterinarian); however, they must have a script and a valid VCPR. This really will not be a changed practice for most livestock producers, rather is reportedly intended to provide more transparency to consumers. Please reach out if you have any questions concerning this implementation.
