Jeana,
I was started on Advair 7 years ago (prior to starting Pulmozyme or Zithro) becuase my FEV25-27 was low, which I think indicates that the smaller airways are not functioning as good. My doctor assumed I had asthma or some sort of reactive airway, and started me on Advair to see if we could get the numbers up. They did go up to the 60's in the next year. I don't know if I've officially been diagnosed with asthma, but nonetheless, the Advair is doing something good.
