dAetomeN, I can't say for sure if the steroid enemas will cause any problems symptom-wise for you, as everyone is different, and it also depends on how long you remain on them. It gets absorbed quickly into your system via the inflammed part of your colon (a topical med), but it also does not need to be metabolized. I've been on them for months at a time with no side effects other than maybe a little nervousness, (but certainly not any puffiness oral pred used to give me!), so I'm all for the rectal usage. Once in remission, I alternate nights (one night using, next night not), and taper off that way.
I believe quincy uses them as well, so hopefully you'll get more info soon.
