Antibiotics Moving to Rx in 2023

Antibiotics Moving to Rx

Animal Antibiotic Changes are Coming in 2023. How Will They Impact Access to Everyday Medications?

The U.S. Food and Drug Administration (FDA) announced in June 2021 that all medically important antimicrobials for food-producing animals and pets will move from over-the-counter (OTC) to prescription (Rx) effective June 2023.

This change impacts any product that contains the following:
  • Oxytetracycline
  • Penicillin
  • Sulfa-based antibiotics (sulfadimethoxine and sulfamethazine)
  • Tylosin
  • Cephapirin and Cephapirin Benzathine
  • Swine medications Lincomycin and Gentamicin

It’s a big deal that’s making waves across the industry, so we want to make sure everyone understands the change and has time to prepare for it.


Changes That Affect Your Animals

In 2018, the FDA laid out its 5-year action plan for supporting antimicrobial supervision by veterinarians. The plan aims to address antimicrobial resistance by only using medically necessary drugs assessed as necessary to treat, control or prevent certain diseases. Licensed veterinarians must determine the necessity, but you won’t have to order the prescriptions from the vet directly. You will, however, need to establish a Veterinary-Client-Patient Relationship (VCPR) if certain animals aren’t examined regularly.


Popular Products Will Require Prescriptions

After months of a penicillin shortage has created supply challenges of its own, soon producers will get hit with this change that once again impacts access to antibiotic therapy for animals. When you’ve used them for so long as OTC meds to treat pneumonia or shipping fever in your cattle or sheep, it’s going to take some getting used to.

Here’s a quick list of some of the popular products at PBS Animal Health that will require prescriptions starting in June 2023.

Filling Prescriptions the Easy Way

Even though there will be extra approval and paperwork involved on these orders in the future, we do have some good news: PBS Animal Health’s Pharmacy Process streamlines the prescription filling for you.

While some sellers of these products may find it easier to pull them from the shelves because they don’t have the capability to legally operate as a “Pharmacy,” PBS Animal Health is already a certified Safe Pharmacy that has sold prescription medications for decades. It’s just another reason why you can trust and rely on us (especially during times of change like these).
