hmm, I do think my kids drink more when on zyrtec, but since they are older I haven't paid much attention to it. I know when I take it, it dries me out a lot and I drink just to make my mouth and throat feel less dry. As far as the dipes, what goes in has to come out lol
Yup, antihistamines dry you up so you end up feeling thirsty.<br><br><br><img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/oops.gif" style="border:0px solid;" title="oops">T I found out recently from my pharmacist that in some children, especially the very young, Zyrtec can supress impulse control. Just something to watch for.
