# Should I give my child Zyrtec or Claritin in the morning or at night? Canonical URL: https://kintoolkit.com/questions/childrens-zyrtec-claritin-morning-or-night The US Zyrtec and Claritin manufacturer FAQs say their products can be taken at any time of day. Follow the interval and daily limit on the exact package. If drowsiness is the concern, ask the child’s clinician or pharmacist about it before changing the schedule. ## Zyrtec can cause drowsiness The syrup, both chewable strengths and Dissolve Tabs warn that drowsiness may occur. Their warnings also require checking with a doctor or pharmacist before use with sedatives or tranquilizers, which can increase drowsiness. A drowsiness warning does not turn an allergy medicine into a sleep medicine or supply a new bedtime schedule. - [Zyrtec timing FAQ](https://www.zyrtec.com/faq) - [Syrup warnings](https://www.zyrtec.com/products/zyrtec-children-allergy-syrup) - [2.5 mg chewable warnings](https://www.zyrtec.com/products/zyrtec-chewables-children-2-plus) - [10 mg chewable warnings](https://www.zyrtec.com/products/zyrtec-chewables-children-6-plus) - [Dissolve Tabs warnings](https://www.zyrtec.com/products/zyrtec-children-dissolve-tabs) ## Claritin’s timing guidance is separate The manufacturer permits Claritin with or without food and at any time of day.
