what is cetirizine used for

Cetirizine is an antihistamine medication used to relieve allergy symptoms such as itchy eyes, runny nose, sneezing, hives, and itching. It works by blocking the effects of histamine, a substance released by the body during an allergic reaction. Cetirizine is commonly sold under the brand name Zyrtec. It is known as a non-drowsy antihistamine, meaning it is less likely to cause drowsiness than other antihistamines. Cetirizine can be used to treat hay fever, conjunctivitis, eczema, and other allergic reactions. It is generally safe to use during pregnancy and while breastfeeding, but it is always best to consult with a doctor or health visitor before taking any medication.
