Drug reactions are common in veterinary medicine. They vary from clinically visible cutaneous reactions with rapid onset to subtle, often delayed reactions that are more difficult to diagnose.

Drug reactions can be divided into immunologic and nonimmunologic reactions. Immunologic reactions are subdivided into Type I (ie, IgE-mediated), Type II (ie, cytotoxic), Type III (ie, immune complex deposition), and Type IV (ie, delayed-type and cell-mediated) hypersensitivity responses. Nonimmunologic reactions include both predictable reactions and less predictable reactions. Predictable reactions include cases of drug toxicity or interactions, while less predictable reactions include idiosyncratic reactions. Diagnosis and treatment depend on reaction type.
