Doctor :   Many cases of ordinary urticaria are "idiopathic," meaning no cause is known.

Doctor :   The goal of treating most cases of ordinary urticaria is to relieve symptoms while the condition goes away by itself.
Doctor :   The most commonly used oral treatments are antihistamines, which help oppose the effects of the histamine leaked by mast cells
Doctor :   The main side effect of antihistamines is drowsiness.

Doctor :   Oral steroids (prednisone,} can help severe cases of hives in the short term, but their usefulness is limited by the fact that many cases of hives last too long for steroid use

Doctor :   Acute urticaria may progress to life-threatening angioedema and/or anaphylactic shock in a very short period of time, although it usually presents as rapid-onset shock with no urticaria or angioedema.

Doctor :   The mainstay is avoidance of further exposure to the antigen.
Doctor :   Antihistamines, primarily the older sedating antihistamines that block the H1 receptors, are the first line of therapy for urticaria.
