Acute urticaria is nearly always due to some defined exposure to a drug or physical stimulus or an acute infectious illness. This may be caused by IgG binding, not IgE. Mechanisms other than allergen-antibody interactions are known to cause histamine release from mast cells. See the following image. … What the first 10,000 patients with chronic urticaria have taught me: a personal journey. (See Etiology. This process can be the result of an allergic or nonallergic reaction, differing in the eliciting mechanism of histamine release.[17].

Non-sedating antihistamines that block histamine H1 receptors are the first line of therapy. Ann Pharmacother. [39], People who do not respond to the maximum dose of H1 antihistamines may benefit from increasing the dose, then to switching to another non-sedating antihistamine, then to adding a leukotriene antagonist, then to using an older antihistamine, then to using systemic steroids and finally to using ciclosporin or omalizumab.
