I have to wonder if the bacteria in Visboime, or any or any or probiotic species, are not immediately obliterated in the presence of metronidiazole and/or fluroquinilone antibiotics.
My treating gastroenterologists have raised the same question as far as taking antibiotics and probiotics together. It seems like the probiotics would be defeated by the antibiotics, but it may have something to do with exactly what probiotic strain mixes are being used. I did try using VSL#3 (or so called at the time) alone, but it had no effect whatsoever and was like taking a very expensive placebo. My GI at the time was highly skeptical about VSL#3, but did say it worked for some people, but apparently not many.
Apart from that question about probiotics as a useful treatment, I do agree with the strategy of using both cipro and flagyl together as I found that much more beneficial than using either one alone.
Its also true that I found a large number of antibiotics effective and was seemingly mostly immune to the side effects of all them (with some exceptions discussed below), but I had my best results with the cipro - flagyl tandem. The others worked, just not as well. And I found that the dosage mattered for me, until I was able to wean off them using Remicade.
I was at one time using 1000 mg cipro and 1000 mg flagyl and was on it for a long time, and I think the failure to rotate created side effects, namely a breakout of yeast infection and warts that my then dermatologist called the "worst I have seen in 30 years of practice." A combination of rotating onto xifaxin (not systemically absorbed) and diflucan snapped the yeast infection after around 1-2 months, and the warts had to be frozen off, some in multiple appointments.
One other side effect of cipro is it will seriously sensitize you to sunlight. I have a darker complexion and tan easily, and I noticed I would burn much faster when on cipro. Therefore, a lot of sunblock is needed when on it, otherwise long forays into the sun will be painful.
Other antibiotics that worked well for me were augmentin, levacquin, and keflex. All were in my rotation at one time or another. Cipro and Flagyl are the go to antibiotics for pouchitis and I think they are meant to be together, sort of like Laurel and Hardy, Abbott and Costello, and Batman and Robin, just to name a few other famous duos.
