I just went to the doctor very sick with congestion, fever,
cough, nasal drip, sinus pressure. She told me she thought I might have COPD, and if things did not clear up she also gave me a prescription for Prednisone. I told her I do not want to take it, but she gave me the prescription anyhow in case I needed it.
I am looking for some information myself as to what is it supposed to do for you.
