Why veterinary medicines not indicated for human purpose?

Veterinary medicines are specifically formulated for the unique physiological and metabolic needs of animals, which can differ significantly from humans. These medications may contain dosages, active ingredients, or formulations that are not safe or effective for human use. Additionally, the safety and efficacy of these drugs have not been tested in humans, posing potential health risks. Using veterinary medicines in humans can lead to adverse reactions or ineffective treatment.
