My pulmonologist gave me prednisone that I can use if I have an exacerbation. I take 20 mg tablets daily for five days. It gets rid of the shortness of breath quickly, and saturation goes up so that I can double the exercise without having to stop and rest. The PFT tests don't show asthma, but it's suspected. I try to only use it every six weeks or more when the SOB is keeping me home, and isolated. This last time I took 10 mg of prednisone instead of the 20 mg. I took those for six days. I was able to put double the steps on my fitbit, and got up to 8,000 steps one day. I think the less prednisone the better, but will confirm that at my next doctor's visit.
I don't understand why it makes a difference. I have moderate-severe emphysema, and weather changes are a trigger that cause things to fluctuate often. I have very fair skin, and the prednisone has caused it to be very thin. I don't know how harmful the infrequent dose I'm taking is. I've become such a hypochondriac!!
