I am taking prednisone to alleviate scar tissue on lower lungs. I also have COPD, PAD, heart disease and Stage 4 Kidney Disease. Per my Dr., the protocol has been as follows: 40mg perday until symptoms improve (which was 20 days), then decrease to 30 mg per day for 3 days, and then 20 mg per day for 3 days, and then 10 mg per day until back to normal. Then stop. what is your opinion of this protocol?
