Just because you can't tolerate Pentasa doesn't mean you won't be able to tolerate other 5-ASA's, Cammy. There are any number of us who can't tolerate Asacol but do well on Colazal. To be truthful, my doctor changed me from Pentasa back to Colazal when I started with him, because he said he hasn't seen good results with Pentasa for UC. So ask your GI about
other 5-ASA options before you give up. I think some state health systems use Colazal last because of the cost involved, which makes perfectly good sense. But I also think in your healthcare system, as in ours, the patient who advocates well for himself comes out ahead.
As for antibiotics, as everyone said, if you need them, take them. It wouldn't do to die from pneumonia while you're preventing a flare, now, would it? You should be able to find a good probiotic over the counter, and take it at least two hours after the antibiotic. This will help keep the good bacteria in your colon from being eradicated.
Hope you're soon feeling better!
