I'm allergic to a lot of antibiotics. Most recently, I was rotating bactrim, xifaxan, oral vancomycin, and doxycyline. I also had tindamax for awhile. Last thing he has me do was rotate just one week for each. But also have had problems with a few of those on the list causing serious side effects. So right now on an antibiotic holiday and trying to figure out what to do next.
