Brand names: Childrens Zyrtec
# Cetirizine Overview Cetirizine is a medicine used to treat allergy symptoms like sneezing, runny nose, itchy eyes, and itchy throat. It works by blocking your body's reaction to allergens, which are things that trigger allergies like pollen, dust, or pet dander. This medicine is an antihistamine, which means it stops your body from releasing chemicals that cause allergy symptoms. Many people use cetirizine to feel better during allergy season or when they're around things that make them sneeze and itch. Before taking cetirizine, there are some important safety things to know. You should not use this medicine if you're allergic to cetirizine or similar drugs. Talk to a doctor before using it if you have kidney or liver problems, or if you're pregnant or breastfeeding. Cetirizine can make some people drowsy, so be careful if you need to drive or do activities that require focus. Always follow the dosage instructions on the package, keep the medicine out of reach of children, and store it in a cool, dry place. If you have questions about whether cetirizine is right for you, ask your pharmacist or doctor.
