I was exposed to C-Diff while taking care of my father 4 months ago. He was eventually hospitalized and diagnosed with the condition. I was tested but the test came back negative. At the time, I was also on an antibiotic for a boil. A couple of weeks later, I developed diarrhea and for three months have dealt with varying degrees of it. I mostly have loose stools but I go three or four times a day. I don't feel sick, have a fever or chills. I was given a diagnosis of IBS but referred to a Gastroenterologist by my PCP. This doctor did another test and after three month I had a positive diagnosis for C-Diff. He gave me Flagyl for 7 days (I thought it was supposed to be 10 but okay) but the loose stool continued. Then he started me on Vancomyocin , 125mg. for 10 days. I had about three days where I thought I was getting, my stools were getting more solid and then bam back to the multiple times per day loose stool. Last night, he started me on Dificid. I know it is early (2 doses) but not much has changed though my stools do seem a bit larger. I'm scared to death this will not work and I'm afraid I'll never get rid of this (okay I'm being overly dramatic I know). But what is the next step if this fails? He gave me a refill so I assume he would want me to repeat a trial of Dificid. I wonder if it would help to take Vancomyocin again if Dificid fails but at the 500mg. strength. Do I need a stood transplant? Again, I feel okay, maybe a little fatigue but no stomach pains just this diarrhea that just hangs on and on . But mostly worry. Have others had to do multiple trials of different medications? I know I need to give Dificid time to work and to control my panic. Any suggestions just in case? Thanks.
