urticaria
"I have taken Zyrtec or the over the counter with a similar name like Walzyr, anyway, other than a rare occasional large hive, and probably due to missing a dose.  I have been great.  

But I got this idea (to save more money) that I should have the doctor prescribe citirizine generic.  You would think that would be OK, but I have been broke out in fine hives and a few welts.  Also some spots that are a little dry like my eczema.   My skin has never ITCHED this extremely.  First I had it on upper right arm. WHICH HAS FINALLY RECOVERED, BUT... It continues to move and I break out, all over the last 26 to 28 days. I am switching back to the drug I used before. We will see if it a medication issue.  Wish me luck!"
