Well if both claritin and zrytec work for you you can always alternate.. one year zyrtec one year claritin. This will guarantee that you do not develope a resistance to the mediciation. As far as how long can on take it? I have been on zyrtec since it was introduced. Couldn't take Claritin it gave me palpatations.. Did Allegra, but it wasn't as good for me as the zyrtec. So overall I have been on zyrtec for a little over 11 years.
