allergic urticaria
"This medicine saved my sanity, if not my life!  Months of unexplained pressure hives all over my body had my nerves absolutely shot.  I won't go into the details, but after MANY doctors and countless tests, I finally found a doctor who wanted me to try Atarax, 50 mg 4 times a day.  I was willing to try anything!!  The drowsiness was difficult to deal with for a long time but the hives had pretty much met their match.  I can tell if I'm late taking one or if I've forgotten altogether.  I can't live without them!"
