urticaria
"I've had dermatographism or chronic urticaria for about 1 yr before I started taking Zyrtec. I started taking Zyrtec in January and now I forgot I even have the skin problem! When I first tried this product, the side effects made me extremely sleepy and thirsty. It dried my body out. But the side effects went away after prolonged use. Now I feel like a normal person!"
