urticaria
"I recently had an allergic outbreak of hives ...
My doctor prescribed prednisone 6-day pack and steroid cream.
I tried benadryl first thinking it would help control the itching.  It did not.
I was so miserable from the itching the hives caused I was willing to try anything.

I came across this page about Allegra.   I was prescribed Allegra in the past and it worked really well for my seasonal allergies.  

I decided to give Allegra a try ...  I'm glad i did!!!  It Stopped on the itching and cleared up 80% of my hives in 1 hour...  Thank God this is Over the Counter.

Doctors always tell you to use Benadryl ... it will only make you sleepy and its not very effective at controlling the itch of hives.   Unless you take a very large dose."
