For Ulcerative Colitis, Active "I've been on Asacol 12 pills/day (4 pills, 3x/day), and I've been experiencing headaches at least 2x/week. Also, I've had side effects of fatigue & acne. Whether or not these side effects can be completely blamed on the last 4-5 months of Asacol use, who really knows. But Asacol has helped control my symptoms almost completely."

For Ulcerative Colitis "I was diagnosed 6 months ago with colitis. I started taking Asacol 400 mg 3x a day. I felt great immediately after the 3rd pill. No diarrhea for 2 whole days! Last night, my stomach started that weird rumbling noise. About an hour later, I had a severe headache! One of the worst I have ever had! I was on my 10th pill. One of the side effects of this medication. Be careful, always call your doctor if you have any side effects with this medication. I stopped taking this medicine, it did not work for me."
