You can be on antibiotics with Remicade. In fact, my husband was sick as a dog in the hospital, and one step away from a major colon resection, fighting a crohn's flare and a c-diff infection when as a last ditch effort his GI decided to try remicade. This is when he was taking vancomycin for c-diff, and obviously had an ongoing infection. For him, it was either try remicade and try to keep c-diff under control with vancomycin, or go with major colon resection. I am so glad that they chose remicade. So far, the only side effect that my husband has from remicade is joint pain and fever for about 36 hours after infusion. Then, all is well.
Fistulas and antibiotics for fistulas, are part of crohn's disease, and you can definitely take remicade if that is what you are taking antibiotics for. If you have bronchitis with fever on the other hand, they probably will hold off on the infusion until you can get rid of the active infection.
I hope you find relief with remicade. Lots of people do - I hope you'll give it a shot, and that it'll help you heal.
