urticaria
"It has been 2 years since I've suffered with Chronic Hives.  Like many on this board, nothing has worked.  After a severe outbreak of hives, and a visit to my Doctor, he put me on Xyzal. I can say I'm about 95% hive free.  I still have some hives but they're not as many or as large.  It is very early with this treatment to say that it will continue this way.  But, for the first time, I am hopeful.  I will return to this forum to give updates."
