# Can I use children’s Zyrtec for a 10-month-old?

Canonical URL: https://kintoolkit.com/questions/childrens-zyrtec-10-month-old

A 10-month-old is under the age range with an amount listed on the US Children’s Zyrtec syrup label. For children under 2 years, the label says to ask a doctor. KinToolkit therefore shows no infant dose.

## What the under-2 result means

Children’s ZYRTEC 1 mg / mL, age band Under 2 years: Ask your child’s doctor before using this product. No dose is shown for this range.

Do not estimate an infant amount from the older-child row or from weight. This public reference cannot replace an individualized instruction from the child’s clinician.

## If a clinician has given instructions

Confirm the exact medicine, concentration, amount, measuring device and schedule with that clinician or a pharmacist if anything is unclear. The absence of an amount here does not evaluate a clinician’s individualized recommendation; it marks the limit of this OTC label lookup.
