According to the AVMA Principles of Veterinary Medical Ethics, it is unethical for a veterinarian to write a prescription or dispense a prescription drug outside a Veterinarian-Client-Patient Relationship (VCPR). The AVMA Principles state that the VCPR is the basis for interaction among veterinarians, their clients, and their patients and requires all of the following for a VCPR to exist:
- The veterinarian has assumed the responsibility for making clinical judgments regarding the health of the patient and the client has agreed to follow the veterinarians' instructions.
- The veterinarian has sufficient knowledge of the patient to initiate at least a general or preliminary diagnosis of the medical condition of the patient. This means that the veterinarian is personally acquainted with the keeping and care of the patient by virtue of a timely examination of the patient by the veterinarian, or medically appropriate and timely visits by the veterinarian to the operation where the patient is managed.
- The veterinarian is readily available for follow-up evaluation or has arranged for the following: veterinary emergency coverage, and continuing care and treatment.
- The veterinarian provides oversight of treatment, compliance, and outcome.
- Patient records are maintained.
The majority of states prohibit veterinarians from prescribing animal medications outside of a VCPR. The following table provides a summary of the VCPR rules in each state, including those states that have incorporated the AVMA Principles of Veterinary Medical Ethics in their practice acts or regulations.
