Match the Children’s Zyrtec bottle and its printed concentration, then choose an age range. This calculator uses age ranges for cetirizine; it does not use a child’s weight to generate a dose.
The cetirizine flow offers Under 2 years, 2–5 years, and 6–11 years. Selecting Under 2 directs you to ask your child’s doctor. For other ages or an unlisted bottle, ask a pharmacist or doctor.
