I take them religiously but I can't say whether they help or not. I don't notice too much of a difference.
I wouldn't stop using the Remicade if it is helping. How old is your father?
I have heard if you stop using it, it may not help as much if you need to start it again. Usually people with UC do flare up again at some point in the future and sometimes the flares are not easy to control (as you know).
I hope you have goodluck with your j-pouch surgery. You're lucky to be done with this disease. It's too bad your father is dealing with this.
Diagnosed with mild proctitis in March 2007: Treated with Canasa (as needed)
December 08: Began treating with Asacol 400mg (9/day) + Canasa 2x/day - Anemic
May 09: Off Canasa, taking Asacol (9/day)
Back on Canasa every other night + Asacol (9/day) + Probiotics + Iron
Reducing to 6 Asacol/day + Canasa + Probiotics + Iron - So far so good!!! -SPOKE TOO SOON! Back to 9/day...
