urticaria
"I was diagnosed with Chronic Idiopathic Urticaria 3 months ago. I have dermographism, where my skin itches during the day, and if I scratch it, I get terrible red patches on my body which stay for an hour or two and looks terrible. I tried every single second generation antihistamine and non of them helped. Zyrtec finally gave me the relief I wanted. I take one pill in the morning with no side effects and I almost don't feel any itch during the day. Since I don't itch, I don't need to scratch myself and don't get hives. I give 8 starts because it doesn't completely cure CIU, but it helps me to manage my symptoms."
