I have chronic cuffitis and chronic pouchitis and IPS. I use Canassa at least 5 days a week and when things are more inflamed also use Anucort making 2 suppositories in a day. I find it hard to manage and use them when I feel I can leave them in for 3 hours but sometimes it's difficult. That is why it is important that I use Canasa so often. My GI initially said to use Canasa daily and the Anucort when needed too. He said that many people stay in remission for a long time but that at that time he had patients that needed to use them several times a week to avoid flareups. I ended up in that category. My cuffitis is now more like pouchitis in that I haven't have bleeding in a long time. I am now also rotating antibiotics and probiotics.
We each have to find what works for us and it is difficult. It's taken me over 4 years and a lot of pain to get some kind of regular routine that minimizes the inflammation in my entire j-pouch.
As Jan said, mine are 1,000 strength.
