Mesalamine
"It 'sort of' worked for the first few months after my diagnosis, but I was still having symptoms of blood about every other day. The only side effect was some increased hair loss (very noticeable to me, but not to others). It's kind of messy and uncomfortable, terribly awkward if you are sharing a bed with someone, and you are supposed to lay still for awhile after you take it, which is a problem for an insomniac. I switched medications to Canasa when I was going to be traveling for a month because a month's supply of Rowasa would have taken up half my suitcase. Canasa ended up working MUCH better and my symptoms were mostly gone a few months after I switched."
