I have a cough with any deep inhalation, it vanishes within 5-10 minutes with 10-20mg prednisone. I'm told that the steroid takes at least 20 minutes to enter the system and take effect. I find beneficial effects sometimes occur within a minute or two.
I'm told that my effect must be placebo - i'm prepared to accept that, (but will do some more testing (double blind) first). Could Prednisone have another property, apart from the steroid affect, that could be assisting my breathing?
