Right Answer

Physical factors (cold, heat, sweating, exercise, pressure, sunlight, water and vibration), infective, vasculitic, psychological and idiopathic may all trigger urticarial reactions. These factors trigger histamine release from mast cells in the body, which induce interaction of both H1 and H2 histamine receptors. The mainstay of treatment remains H1 antihistaminic drugs like levocetrizine 5 mg which can provide relief from urticaria.
