How do Children’s Zyrtec liquid, chewables and Dissolve Tabs differ?
Children’s Zyrtec allergy products contain cetirizine HCl, but the liquid, 2.5 mg chewable, 10 mg chewable and 10 mg Dissolve Tabs have separate directions. Match the exact package; this comparison is not a conversion or substitution chart.

These are allergy formulations, not Children’s Zyrtec Hives Relief or combination products. Matching ingredient does not establish that products can be combined or substituted. Check the actual package and ask a pharmacist about differences before use. Only the syrup is supported by KinToolkit’s calculator.
Cetirizine warnings include drowsiness and precautions with alcohol or sedating medicines. The FDA also warns about rare severe itching after stopping long-term cetirizine use. Ask a healthcare professional about this risk; this page supplies no stopping or tapering schedule.
