I was prescribed Rifaximin + Vancomycin for my SIBO. That'll be the second time I take Rifaximin, the last was 2 years ago with Neomycin. Ok so, there were no problems but also not much improvemenet that time. I felt like i was finally getting good improvement in the end of the treatment like the last 2-3 days (i took it for a month) But then i stopped cause it was already long enough and the effects decreased back to normal. Now I'm suposed to take it again, with no SIBO test since I can't get it on my country but based on symptoms. And when I took the first time I was kind of desperated, now I'm way better and I fear getting worse or developing some kind of other disease. Any experiences, knowledge to share?
