i'm currently on prednisone for the second time
first time i took it, started at 40mg, and it kicked in very fast..i'd say within 3 days i noticed improvement...if not 3 days, definitely within a week!
this time, i started on the iv pred while in the hospital, and that kicked in very fast of course because it was iv... so within an hour i felt it... now i'm on 30mg tabs, day 3...it's still working! i'm on a bit of a lower dose and faster taper this time too, so i'll see how i do this time. last time i tapered much too quickly and had horrible withdrawal symptoms and severe crohn's symptoms (came back like a monster, it was the worst)
