I was on the Singulair first. It was prescribed for my Asthma as well as my allergies. I was also on Allegra-D, Flonase and Astelin for my allergies. (I already finished a round of immunotherapy prior to going on the Singulair.) It was about a year later that I was also diagnosed with the acid problem. I had a PH test to confirm it. That was when I went on the double dose PPI.

The combination of treatments helps me because the asthma and acid problems seem to aggrevate each other. Whenever I have problems with one, it sets off problems with the other. The dual treatment helps me get them under control together.

By the way, I have the same symptom for both conditions---a chronic dry cough.
