allergic urticaria
"Hydroxyzine has been the magic bullet for my skin allergies.  I've tried every over-the-counter option, as well as a couple of prescriptions.  I was warned that hydroxyzine might make me more sleepy and wiped out than the other drugs, but for me it has nearly no sedative effect.  My hives, which used to appear over much of my body for several hours a day, stay away almost completely."
