hi everyone,
Can anyone tell me if there are any difference between zirtek and piriteeze i know their both cetirizine 10mg, but i normally take piriteeze as i'm allergic to piriton and my asthma nurse told me to take 2 zirtek tabs if the piriteeze didn't stop the hayfever and if it's the one a day tablets can i take 2 of them cos i don't want to overdose self.
