I haven't given advice here, just received it... so take this answer with a grain of salt! My neurologist recently ordered prednisone for me and the instructions on the scrip bottle were to take 5 for 5 days, 4 for 5 days, 3 for 5 days, 2 for 5 days, 1 for 5 days, and finally .5 for the remainder. I think that is the taper.
Learning here requires learning a new language, much of it cryptic. Warning: for me, prednisone has bad side-effects like mood swings and generally being a pain in the ass to those around you.
