I've had diarrhea since last week. I had ciplox-tz (ciprofloxacin+tinidazole) for 4 days along with vizylac (pro biotic). I was recovering and my stools had somewhat normal consistency. But a day or two after stopping I developed diarrhea again. I visited a physician who prescribed vibact DS which is a better pro biotic than vizylac and no antibiotic. Even after this I'm still having diarrhea. Please help.
