However, it is vital for horse owners to consult with a veterinarian before administering any medication. Horses are large and powerful animals, and their physiology can react differently to medications compared to smaller pets. A veterinarian has the knowledge and expertise to prescribe the appropriate medication based on the specific symptoms and the health history of the horse. Additionally, inappropriate use of cold medicine could lead to adverse reactions, potential allergies, or masking symptoms of a more serious condition that requires alternative treatment.
