I have been on 6MP for about
a year. My Gi added it about
2 months after I started taking Pentasa. Unfortunately, I was starting a flare at that point and it was progressing quickly. I don't really recall any side effects from the medication. I take 100 mg every morning. After my two resections in Oct/Nov last year and in combination with Remicade, my Crohn's has gone into remission. I continue to take the meds for maintenance now.
