Hi..are you seeing a GI? Where in your colon is your UC...limited or throughout?
What other meds are you on?
The antibiotics are for bacterial infection such as clostridium difficile (c. diff). Did your doctor do stool samples?
Have you had a colonoscopy done and what were the results?
Were you diagnosed with "colitis" or actually Ulcerative Colitis?
It's all a matter of perspective!
