I think before you directly switch to Canasa, you should do the Rowasa every second night and replace the non-rowasa night with a Canasa. Do that for a week, then go to every third night with the Rowasa and the Supps on the non-Rowasa nights...continue till you're on the Canasa nightly.
I personally think the Rowasa would be better regarding medication per dosage, but I did use suppositories in the past (tapering to use them)..but worth a try.
You should, however, call the doctor and ask for clarification regarding the method. If she wants you to go directly to the supps nightly...try it. If you start to have symptoms, at least you have the Rowasa...
How long were you on the Rowasa nightly?
