Entocort is targeted mainly at the terminal ileum, so I'm not sure whether that would be best for you.
Anyway, it is OK to take up to two Entocort when you have tapered down to 20mg prednisone. Then, assuming your pred taper continues to go OK (20mg and below is when it becomes trickey), on the day you taper down to zero pred, take 3 Entocort.
This is what my daughter did with her doc's blessing...we were afraid she might end up back in the hospital if the pred taper didn't work. So used Entocort to get her off the pred...she went off pred slowly after getting down to 20 mg, tapered by not more than 5 mg a week.
Stayed on Entocort for years - after all, it was trying to taper off Entocort that landed her in the hospital. Used LDN months ago to get off Entocort and seems to be fine.
The manufacturer of Entocort used to issue a warning saying not to take more than 2 pills Entocort while on pred, but I didn't notice that warning the last time I checked the latest ENtocort prescribing instructions.
So yes, 2 pills of Entocort can be as effective as pred for SOME people. And Entocort can be used to taper off pred. And yes, you can take ENtocort while on pred, but it is best to check with your doc and introduce Entocort only when you have tapered down to 20mg pred or lower.
