NSAID-induced reactions can be classified into 5 categories: (1) NSAID-exacerbated respiratory disease (NERD); (2) NSAID-exacerbated cutaneous disease (NECD); (3) NSAID-induced urticaria and/or angioedema (NIUA); (4) single NSAID-induced urticaria/angioedema/anaphylaxis (SNIUAA); and (5) single NSAID-induced delayed hypersensitivity reactions (SNIDR) [2]. Patients in the first 3 categories react to NSAIDs from various chemical groups in a nonallergic type of drug hypersensitivity known as cross-intolerance. The mechanism involved in these reactions is thought to be related to an imbalance in the arachidonic acid metabolic pathway leading to increased release of cysteinyl leukotrienes.
