I would think if you were on a higher dosage or for a very long extended period or if you are super sensitive, it could have side effects that aren't pleasant....but it is a lower dosage med and doesn't dissolve in the stomach and go through your body systemically in order to combat the inflammation, it's a topical med that's released into the ileum and colon.
It will, however, have some of the med pass through the colon wall and eventually into your bloodstream, but in a MUCH smaller amount that if you were on prednisone.
I wouldn't want to take pred, but I would consider entocort if necessary firstly.
I do hope you are using rectal meds as well....
