Hi. I am recently diagnosed with ileitis, most likely crohn's. I also have knee swelling. I was initially put on Lialda, but it seemed like Lialda gave me more diarrhea. I asked my doctor to prescribe me Pentasa, which is more directed at the terminal ileum. Will the Pentasa likely work, or will I likely experience the intolerance that I had with Lialda. My doctor also put me on entocort. Unfortunately, my insurance doesn't cover Pentasa right now, so I am also in the process of appealing and changing insurance so that I can get Pentasa. Any advice would be appreciated.
