I have had an annoying cough for the longest. Went to every doctor and had a bunch of tests done from asthma to GERD. All negative. Found it it was like a combo of allergies and post nasal drip. Went on Zyrtec and it helped. That was a year ago. Now, I think the Zyrtec isnt working. 2 months ago, I added Singulair to my meds. I also added Flonase, Astelin, Nasonex and Rhinocort. Helped a little. But I still feel the need to cough throughout the day to clear some mucus or sometimes it clears nothing yet I still have the urge to cough----althouh not nearly as often as I did! Could the Zyrtec have no effect anymore since I have been taking it everyday for a year (just started Clarinex yesterday)? What other allergy meds and nasal sprays would be right to fight the PND and allergies? Thank you for any help.

I am also a year into allergy shots...who knows if they are even working. lol

singular it has helped me
good luck

Hate to tell you but Zyrtec, Flonase, Singulair, Astelin, they are the best of the allergy meds. you might want to make sure you don't have a sinus infection that is causing the problem. Also, have you tried sinus irrigation? Irrigation, plus the meds have made a big difference for me.
