Dear Doctor, I am an ulcerative colitis patient. About 4 months ago, I started to feel the onset of an active phase of the disease. I had a stool analysis. The result showed: Pus Cells: 8-10 R. B. Cs: 2-3 The doctor prescribed Pentasa. I had taken Pentasa 3 gm per day (2*500 mg three times a day) for over 2 months. During that period I could see blood and mucus in the stool. Over time, I felt better and I thought the active phase of the ulcerative colitis is over. To be sure, I had another stool analysis yesterday. The result shows: Pus cell: 3-5 R. B. Cs: 10-15 I don t see blood (as I used to do before) and I feel a lot better than at the time of the first analysis. Do I continue taking higher (than maintenance) dose of Pentasa? I am male 58 years old. Thanks for your reply.
