I have been on Cellcept for about 11 years, IVIG for about 6 years and over the last 6 years I have been off and on prednisone, depending on whether I was on crisis or not.

I had no problems taking all 3 at one time (except for the regular prednisone side affects)

I am currently on weekly IVIG, 3,000 of Cellcept daily and 10mg of prednisone every other day.

Hope this helps.
