It is my understanding that many antibiotics are sulfa based. Some IBS symptoms (bacterial overgrowth or H.Pylori) are treated with antibiotics but I doubt UC is treated with antibiotics. Here are just a few common sulfa based antibiotics: Penicillin, Amoxicillin, Tetracycline, Doxycycline, Zithromax & Ciprofloxacin.
