As you check with your GI doc on alternatives. A new drug for Chrons patients has been recently approved for U/C. Check on Cimzia. www.cimzia.com
As this disease effects us all differently -
I'd check a few more drugs before surgery. I was very healthy on Immuran for several years straight - with zero flair-ups. I'm was very active - and happy. It has stopped working recently - and I am weening off the Immuron and onto a new Immune Surpressant, Cimzia, which is a monthly injection you can give yourself.
Just a suggestion for research - best of luck.
Daily: 100mg Immuron, 6x400mg Asacol.
Monthly: inject 400ml CIMZIA
