urticaria
"Zyrtec never helped my runny nose or itchy eyes but it eliminated about 90 percent of my hives, and for me, that might as well be a hundred percent. My hives came on gradually and worsened over the years. It got to the point where my skin burned and itched pretty much 24/7. When I started taking Zyrtec regularly I noticed immediate improvement. Before I had just assumed my post shave rash was normal but now I know it was my hives response."
