Depends: The combination can cause increased drowsiness; however, if you are taking zyrtec for allergies and you have an allergic reaction, you can take an additional benadryl (diphenhydramine). You should always discuss these interactions with your doctor.

No: Both zyrtec and Benadryl (diphenhydramine) belong to the same class of medicines called antihistamines. Taking both at the same time would be taking a double dose of medicine. Zyrtec is taken once every 12 hours, whereas Benadryl (diphenhydramine) is taken every 4 to 6 hours.
