Section 811.12.2. Controlled substances, drugs, prescription medications and restricted immunization products.  


Latest version.
  • When state or federal law restricts a drug, medication or immunization product intended for use by or on the order of a licensed veterinarian, the licensed veterinarian shall sell, distribute, or order the drug or medication only in the course of the licensed veterinarian’s professional practice. A prescription veterinary drug, medication or immunization product shall not be deemed to be used “in the course of the licensed veterinarian’s professional practice” unless a valid veterinarian/client/patient relationship exists.

             12.2(1) Prescriptions. The order for all such drugs, medications or immunization products shall be accompanied by the licensed veterinarian’s original prescription that shows the following:

                a.               Licensed veterinarian’s name, address and telephone number;

                b.               Client’s name;

                c.               Patient’s name or identification;

                d.               Date issued;

                e.               Drug, medication or product name, strength, and quantity;

                f.                Directions for use;

                g.               Number of times the prescription may be refilled;

                h.               Expiration date of the drug, medication or product; and

                i.                Applicable withdrawal period (paragraph 12.2(2)“d”) for livestock and poultry.

             12.2(2) Extra-label use of veterinary drugs, medications, and immunization products. Any extra-label use of veterinary drugs, medications or immunization products shall be by or under the order of a licensed veterinarian only and shall be subject to the following criteria:

                a.               There shall be a veterinarian/client/patient relationship as defined in subrule 12.1(1).

                b.               For drugs or medications used in patients not intended for food, one of the following applies:

                 (1)             There are no marketed drugs, medications and immunization products specifically labeled for the condition(s) diagnosed;

                 (2)             The approved product is clinically ineffective; or

                 (3)             In the licensed veterinarian’s clinical judgment, the labeled dosage is inappropriate for the condition or the extra-label use should result in a better outcome for the patient.

                c.               The health of the treated patient is immediately threatened, or suffering or death would result from a failure to treat the affected patient.

                d.               Appropriate withdrawal period shall be specified when the drugs, medications or immunization products are used in animals intended as food. Extra-label drug use in food-producing animals must follow Food and Drug Administration - Animal Medicinal Drug Use Clarification Act regulations (21 Code of Federal Regulations 530). Licensed veterinarians are encouraged to consult the Food Animal Residue Avoidance Databank (FARAD) or public peer-reviewed documents when determining appropriate withdrawal period.
