A member asked:
My 3.5 year old took 7.5 ml of zyrtec 6 hours ago. can he have benadryl (diphenhydramine) now, and how much? he is sneezing and has a running nose.

Runny nose : Depends how many mg is in 7.5 cc , but if Zyrtec dose was daily dose you need to wait close to 13 hours before Benadryl (diphenhydramine) ....you should also give him fluids to drink, salt water drops for nasal drainage ...
