@losthope I read a study that was done in 2011 regarding vancomycin vs fidaxamicin (Dificid). The major difference is that Vanco also kills your good bacteria. The Dificid only attacks the Cdiff spores. Without that good bacteria the Cdiff spores just continue to flourish. I had people wonder why I kept having relapses after taking Flagyl and Vanco twice (once for 10 days and once doing the Vanco taper). I felt like they didn't think I was cleaning the bathroom or washing my hands enough. People don't realize that Cdiff is hard to kill and except for Dificid, the other treatments are also killing your good bacteria along with Cdiff spores. There's also two different strains of Cdiff. You could also have a different strain than the original infection. This week, on the 26th, it will be three months since my 4th bout with Cdiff. Prior to taking Dificid, three weeks was the longest I had gone without relapsing. I wish you well in 2019.
