How long does it take childrens claritin to work?

1-2 weeks

Claritin
If there are absolutely no improvements in about a week, I tend to switch people over to Zyrtec. It can be a little sedating for some, but I have found it to be MUCH more effective than Claritin.

How long should it take for my Claritin to work?

Up to 1 hour

Allergy_testing
Claritin can work relatively quickly in most people. That is, it usually works within 30 minutes. However, in some people it may take up to 60 minutes to have its full effect. If it is not working within that time, or if the duration of effect becomes less and less, seeing an allergy specialist for allergy testing would be recommended as other treatments may be more effective.
