Zyrtec® (cetirizine hydrochloride) is a non-prescription antihistamine commonly used for treating allergy symptoms and itching caused by hives. By blocking the effects of histamine, the medication can help relieve sneezing, runny nose, watery eyes, and itching (due to hives). Zyrtec is available in a variety of strengths and comes in the form of tablets, syrup, and chewable tablets. You should talk to your healthcare provider before using the drug if you are pregnant, have liver disease, or have kidney disease.
