Antibiotics are used widely to fight bacterial infections in humans and animals. However, if the bacteria develop a resistance to that antibiotic, the drug becomes less effective in fighting the infections. For this reason, over-the-counter (OTC) antibiotics will only be available to producers from a veterinarian or with a prescription from a veterinarian.
To ensure the continued effective use of antibiotics in humans and animals, the Food and Drug Administration’s (FDA) Center for Veterinary Medicine has developed a five-year veterinary stewardship plan designed to slow the emergence of antimicrobial resistance that can arise from the misuse of antibiotics in animals while ensuring the safe and effective use of medically important antibiotics in animals and humans.
Many antibiotics are medically important to both human and animal health. The intent of this legislation is to ensure that these drugs are used under veterinary supervision, reducing the chance of antimicrobial resistance to these drugs developing in both humans and animals.
In 2017, FDA placed in-feed and water-soluble medications under veterinary supervision through a veterinary feed directive.
The next steps in this transition will move OTC products to also be under veterinary oversight. As of June 11, 2023, all medically important antibiotics in dosage forms approved for use in animals (such as injectable, intramammary and bolus)—both food-producing and companion animals—will no longer be available OTC.
The drugs will also display the following statement on the label: “Caution: Federal law restricts this drug to use by or on the order of a licensed veterinarian.” Products sold OTC are typically sold at farm and feed stores or by online suppliers.
To obtain these drugs, producers will need a valid veterinarian-client-patient relationship (VCPR) with a licensed veterinarian. According to the Michigan Department of Agriculture and Rural Development (MDARD), a VCPR is considered valid if all of the following apply:
• A veterinarian has assumed the responsibility for making medical judgments regarding the health of an animal and the need for medical treatment, and the client (the owner or other caretaker of the animal) has agreed to follow the instructions of the veterinarian.
• There is sufficient knowledge of the animal by the veterinarian to initiate at least a general or preliminary diagnosis of the medical condition of the animal.
• The practicing veterinarian is readily available for follow-up in case of adverse reactions or failure of the regimen of therapy. Such a relationship can exist only when the veterinarian has recently seen and is personally acquainted with the keeping and care of the animal through examination of the animal and/or by medically appropriate and timely visits to the premises where the animal is kept.
The VCPR does not mean that producers must purchase the drugs from their veterinarian, but it does mean that the distribution of antibiotics will require a prescription from the veterinarian with whom they have a valid VCPR.
Antibiotics can be important to livestock producers for maintaining the health of their animals. It is important that producers are aware of the new requirements to establish a VCPR in advance so they can continue to use antibiotics, when needed, to maintain animal health.
Michigan State University (MSU) Extension recommends that producers who don’t already have a good relationship with a trusted veterinarian start seeking one out and establish that relationship now before an emergency occurs or they need access to drugs that are no longer available OTC.
This will help the veterinarian become acquainted with your individual management practices and the potential needs of your farm. MDARD recommends veterinarians visit a farm once at least every 12 months. — MSU Extension
