I have been taking a combination of Pataday, Zyrtec, Nasonex and Advil for the last 4 years for my seasonal allergies. After last years pollen season I found out that I could not get off Zyrtec due to itching. So I have been taking it ever since once every 3-4 days. Now that I found this site, I dont care if I itch for months, I am quitting. I will never again take a Zyrtec tablet in my life. I'd rather take a few weeks off and go south in May, then end up like this.
