I also stopped taking Allegra for allergy testing, and almost went insane with the itching. I was itchy all over, in my ears, my scalp, my eyes, arms, legs, etc. It was horrible. I had also stopped my daily teaspoon of honey and green tea and my nasonex for the testing, so I wasn't sure what caused it. After testing, I didn't resume anything but the allegra, and I have just now stopped it for 2 days and the crazy itch is back. I'm going to have to take a dose just because I cannot bear this...
