A member asked:

Can you take zyrtec (cetirizine) twice daily?

A doctor has provided 1 answer

Most likely: If you are taking zyrtec (cetirizine) once a day and it does not make you significantly sleepy, you will be fine. A number of conditions are treated with zyrtec (cetirizine) or other antihistamines more than once a day and this is widely accepted.

My son is 10 weighs 113 lbs 4'9" and takes Zyrtec daily but I'm out and can't get any more until the 18th. Would Fexofenadine 180 mg be okay for him? He catches everything at school for some reason when he isn't on Zyrtec.
