allergic rhinitis
"Make the itching stop. I took this for Hayfever and it worked. BUT, it then caused me to have head to toe bumps and itchiness even after stopping taking it. The itching is keeping me up at night. I am hoping to wait it out and never take it again. Also while I was taking it my eyes and face got really, really swollen. I am still not sure if this was from an unusually bad allergy season or the Zyrtec, but I am going to guess it is the Zyrtec because my allergies have never caused this before (usually I just have sinus and itchy eyes).
