A 9 year old has multiple itchy erythematous wheals all over the body for 2 days. There is no respiratory difficulty. Which is the best treatment? (AIIMS Nov 2014)
Acute urticaria is a self-limiting disease. As the basic pathogenesis is release of histamine, only antihistamine is required for treatment. If there is respiratory depression due to laryngophargeal edema, 0.5 to 1 ml. epinephrine is the initial drug of choice.
