Urticarias induced by nonimmunological mechanisms (intolerance, nonallergic hypersensitivity) display either acutely intermittent or chronically recurrent course. The pathogenesis involves the effect of vasoactive biogenic amines, histamine liberators, or a genetic disorder of arachidonic acid metabolism. The aetiology primarily includes food additives (preservatives and food colours), acetylsalicylic acid, and nonsteroidal anti-inflammatory drugs. The article provides an overview of the aetiopathogenetic factors, clinical picture, diagnostic procedures, and treatment.
