Prior to 1996, there were two methods for dispensing new animal drugs: over the counter or prescription. In ‘96, congress enacted the Animal Drug Availability Act (ADAA) to facilitate the approval and marketing of new animal drugs and medicated feeds. As part of that, Congress recognized that certain new drugs intended for animals should only be administered under the supervision of a veterinarian. Their reasoning? Veterinarians are needed to control the use of certain antimicrobials. This is critical for reducing unnecessary use of such drugs in animals and to slow or prevent any potential for the development of bacterial resistance to antimicrobial drugs. Furthermore, safety concerns, relating to difficulty of diagnosis of disease, high toxicity and other reasons may dictate that the use of medicated feeds be limited to veterinarian supervision.
