Hi,
Recently, I have been change to Revlar from Fostair 200 / 6 x 2 times / day. Before starting Revlar I found, that I would occasionally cough up some brown phlegm in the morning. Now, after making the switch, I am finding when I wake-up I have a lot more brown phlegm and not feeling SOB, which I did while taking Fostair. Also, I notice I am able to breathe better on Revlar. Is this brown phlegm short-term or is it sign of COPD as a result of long-term sevre asthma?
FYI I am a non-smoker and house is smoke-free.
