Hypersensitivity reactions to aspirin and other NSAIDs occur in individuals genetically predisposed and exhibit different clinical manifestations, especially respiratory, cutaneous, and generalised. Five different phenotypes define distinct clinical pictures: aspirin-exacerbated respiratory disease, aspirin/NSAID cutaneous disease, NSAID-induced urticaria, angio-oedema and anaphylaxis, single NSAID reactions, and delayed reactions. They are observed more frequently in middle-aged women, and in atopic individuals. While ASA/NSAID hypersensitivity shares comorbidities with asthma, chronic rhinosinusitis, nasal polyposis, chronic urticaria and angio-oedema, ASA and other NSAIDs can also be cofactors for other clinically relevant conditions, especially food-dependent exercise-induced anaphylaxis, angio-oedema induced by angiotensin-converting enzyme inhibitors, and oral mite anaphylaxis. Awareness on these relationships is required for the correct diagnosis, classification, and treatment of affected patients.
