irritable bowel syndrome
"I have taken both the 75 mg and the 100 mg Viberzi,  When I started on this medication, 75 mg it worked somewhat.  My diarrhea was slowed and the stool more solid.  However, after being on it for a month or a little longer the benefits decreased.  I went from having 3 to 4 bowel movements a day, to having 6 or more.  Usual pattern was first movement was the most solid, the next ones were more loose and runny.  My doctor increased the strength of Viberzi to the 100mg.  Same basic issues...worked good at first but after using for a while, I was back to having 6 or more movements with the first one the most solid.  I am again trying the lower dose as the cost of the 100mg was way too expensive, even with Medicare and my supplement drug plan."
