BM changed to liquid after using Rowasa

It sounds like you've been given the generic mesalamine retention enemas rather than the brand-name, which is Rowasa. Some of us posting here have had issues with the generic; though they're supposed to be the same as Rowasa, they may have different inert ingredients. As for liquid bms after use, yes, Rowasa does that-- it doesn't fully absorb like steroid enemas do, so you'll have some liquid sloshing around in your left colon that mixes with stool. I always disliked that aspect of the med & managed to mitigate it somewhat by eating a serving of plain boiled rice daily while on it. My gastroenterologist, who sub-specializes in IBD treatment, said it's common for patients using it to experience liquid bms. / Old Hat (30 yrs with left-sided UC ... [etc.])

RE cold cereal made of rice, puffed rice is the absolutely safest if you're flaring-- no added ingredients. But I do all right with Cheerios & lactose-free milk. The most recent helpful side dish I've found is plain couscous-- seems very soothing to the gut & stays put. The fine variety (sometimes called "French") has been available in the U.S. for many yrs & more recently, the bigger dots, too (called Israeli or Moroccan). It seems very easy to digest. On the other topic: good luck with your sample! If you can't get it, you've got the med to blame so the doctor can't fault you on that! / Old Hat (30 yrs with left-sided UC ... [etc.])
