Is it dangerous to take two zyrtec (cetirizine) in one day?
A doctor has provided 1 answer
No: There are people that are prescribed zyrtec (cetirizine) up to four times a day for various conditions. It should be no problem to take zyrtec (cetirizine) twice a day as long as it does not make you too sleepy when you need to drive or work.
