Xylazine hydrochloride is widely used in veterinary medicine as a sedative, analgesic, and muscle relaxant, particularly for large animals like horses, cattle, and deer. It is often administered to calm animals during procedures such as examinations, surgeries, or transportation. In combination with other anesthetics, it enhances the overall sedation effect, reducing stress and pain for the animal. Additionally, it is used in wildlife management to immobilize animals for tagging, relocation, or medical treatment. However, its use in small animals like cats and dogs is limited due to potential side effects. In some regions, it has been misused as a recreational drug adulterant, posing significant health risks to humans. Proper dosage and administration are critical to ensure safety and effectiveness in veterinary applications.
