Salofalk vs Canasa--are they the same?

Hi everyone! I have used brand name Canasa suppositories for ulcerative proctitis for the last 5 years. It's worked like a charm. No bleeding, diarrhea or any truly intrusive symptoms. I kept in remission using it 2-3 x a week. Maybe 4x if I ate like garbage. In September, 2019 I started with the generic mesalamine . By October I was using the suppositories 6x a week, got joint pain so bad I was screaming, and burning, contact dermititis at the exit. My insurance (US) isn't covering the brand name Canasa any more. But I can get the brand name Salofalk from Canada inexpensively. Both are made by Allergan. The brand name Canasa has "hard fat" listed as a filler. This is rapeseed oil and canola oil. The Salofalk has "Witepsol H-15" listed as the filler. I think this is also a hard fat. Does anyone know if they are meaningful differences between them?

Sorry I have no idea but I use the salofalk suppositories and have found them to be brilliant, first time out of flare in nearly a year, I tried the foam but no joy, I hope it works for you as well

I suppose you could analyse the ingredients.
