I was on 100mg of pred for 3 months, Im currently dropped down to 25mg (been on it for about
a year total), usually I start noticing the side effects going away around 10mg, it really depends how long youve been on it and how fast you taper off...my GI said my side effects might take as long as a month completely off of it for the moon face to go away because Ive been on it for so long, but I have noticed my face has gotten a little smaller since being on 25mg.
