Description
Cetirizine injection is used to treat adults and children 6 months of age and older with acute urticaria (hives, itching, or redness of the skin).
Cetirizine is an antihistamine that works by preventing the effects of a substance called histamine, which is produced by the body. Histamine can cause itching, sneezing, runny nose, and watery eyes. It can close up the bronchial tubes (air passages of the lungs) and make breathing difficult.
This medicine is to be given only by or under the direct supervision of your doctor.
