The summary of product characteristics of Zyrtec do not indicate the possibility of significant interactions. You can expect an increase in side effects such as drowsiness, headache and general fatigue when using both of these drugs, for this reason I would suggest implementing a longer interval than 3 hours (it is best to separate the two preparations and give at a different time of day).
