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 . A prescription is already required for most antibiotics delivered to livestock, and the remaining three categories of injectable antibiotics available over-the-counter will soon be joining the list of medically important antimicrobials that require a veterinarian’s prescription. To add to the stress of raising livestock, now things will change again which is going to influence the ag industry overall. I hope that this list of medications will give people a chance to read it and become familiar with the situation before the change comes in June of 2023. Changes Coming are as follow: In 2018, the FDA established a 5 year plan for supporting antimicrobial supervision by veterinarians. The plans purpose to address antimicrobial resistance using only medically necessary drugs as necessary to prevent, treat and control disease. It has to be determined by a licensed veterinarian if it is necessary, 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 are not examined regularly. Popular Products Will Require Prescriptions Following a recent penicillin shortage, 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 livestock, Now, the change will be to establish the relationship with your veterinarian to get the prescriptions for these meds. Here is the list by active ingredients. The following are some products that will be seeing label changes to prescription-only status: Oxytetracyclines Injectables: Liquamycin LA-200, Noromycin 300 LA, Bio-Mycin 200, Agrimycin 200, etc. Boluses: Terramycin Scours Tablets, OXY 500 Calf Boluses Penicillins (Penicillin G procaine, penicillin G benzathine) Injectables: Penicillin Injectable, Dura-Pen, Pro-Pen-G, Combi-Pen 48, etc. Intramammary tubes: Masti-Clear, Go-dry, Albadry Plus Sulfa-based antibiotics (Sulfadimethoxine, sulfamethazine) Injectables: Di-Methox 40%, SulfMed 40% Boluses: Albon, Sustain III Cattle & Calf Boluses, Supra Sulfa III Cattle & Calf Boluses Tylosin Injectables: Tylan 50, Tylan 200 Cephapirin, cephapirin benzathine Intramammary tubes: ToDAY and ToMORROW Additionally, several swine medications fall under the new guidance: Lincomycin Injectables: Lincomix 100, Lincomix 300, LincoMed 100, LincoMed 300 Gentamicin Injectables: Garasol, Gentamicin Piglet Injection ToDay Mastitis Treatment for Lactating C ows
