A member asked:

Is it safe to take another 24-hour zyrtec (cetirizine) antihistamine if there's still about 8 hours left before the previous one wears off?

You can take another xyrtec but you may become very sleepy.

It's best to adhere to the dosing recommended. It would be hard to overdo it with the zyrtec (cetirizine) , the way you are suggesting, but it begs the question- how well does the rx work , if you want more before the proper dosing interval ? I would think you need to talk with your doctor about other options to achieve safe allergy control. Sometimes more than one rx is necessary.
