irritable bowel syndrome
"I'm baffled by reports of this not working.  I tried Xifaxin and was flushed out for 10 days worse than before then on first day of taking Viberzi it stopped (35 yrs IBS-D tried everything & only Lotroxex worked prior to Blk Box).  It worked with FIRST pill for me. I might suggest doing as I did which was starting on 75mg 2x day then on 2nd week to 100mg 2/day.  I also did extensive research and while I can eat whatever I want One MUST not drink and if you do maybe 1 beer or 1 wine once or twice a week due to liver enzyme and prostrate side effect possibility so NOT for heavy drinkers!  That said, I have been on 3 months now and have had JUST TWO upset stomachs.  THIS IS NORMAL & glad that Rx allows bad food or virus to come thru. VIBERZI #1!"
