allergic rhinitis
"For the past five years I have been treated for everything except an allergy. I was hacking my brains out from October through to May. My doctor said I had GERD, I took Prilosec OTC. Nothing happened. Well, my husband went overseas and brought me back a package of cetirizine. I was desparate so I took one pill and a second.  My coughing stopped. I am in Heaven. Looked it up on the internet and low and behold it's ZYRTEC. I am grateful beyond belief and to top it off no side effects as of yet and it's been two weeks.  First time during the winter I am cough free in years."
