Hi again, and thanks for posting your question - it's a good one!
Just as COPD affects everyone differently, the efficacy of medications can vary from patient to patient, too. As well, side effects that are associated with medications do not necessarily affect each person who is on the medication. However, you'll want to be aware of the physical changes (if any), you experience and report them to your doctor.
Having said that, the progressive tapering of prednisone for your course of therapy sounds to be fairly typical. Naturally, your physician will be monitoring your response to this medication regimen and should be speaking with you about how you are responding to it.
When it comes to the maintenance dose the doctor has mentioned, that, too, can vary from patient to patient. You may want to discuss these plans with the prescribing physician. What do you think?
Please do check back and keep us apprised of how you're doing with this medication this time.
Wishing you well,
