My pulmonologist prescribed Pulmocort and told me if my productive cough went away on the med, it meant I had asthma not COPD. It didn’t. More recently my allergist (who also treats asthma) changed me to QVAR and said the same thing (this time directly addressing my question about whether it could be chronic bronchitis). I just started the QVAR so it’s too early to tell what effect it has on my productive cough. But supposing it eliminates my productive cough, would this mean I have asthma not chronic bronchitis, and why? What if it just reduces my coug?
