Cetirizine Side Effects, How it Works, Upsides & Downsides

Cetirizine is an antihistamine that is used to treat allergy symptoms like watery eyes, sneezing, runny nose, itching, and cold. It can also be used to cure swelling and itching caused by hives. It is available in the form of tablets, and in liquid form. Cetirizine works by limiting the production of a natural chemical (histamine) during an allergic reaction, reducing symptoms like itching, runny nose, watery eyes, and sneezing.

However, Cetirizine should not be used to treat hives or a severe allergic reaction like anaphylaxis. If you have been prescribed epinephrine, use it to treat a severe allergic reaction instead of Cetirizine.
