allergic rhinitis
"Zyrtec worked well to control my seasonal allergies as well as allergies to dust, cats, etc. It seemed to work faster than Claritin. However, when I stopped taking Zyrtec, I developed severe itchiness all over my body. It took a couple weeks to get through the worst of it, but I am still itching after a month. It seems that my skin has become hyper-sensitive to detergents, soaps, contact with clothing, etc. It seems that certain other people are experiencing this as well."
