I've done a little research on which antibiotics are more likely to cause a flare of C diff. And that one is one of the ones I will not take. So be vigilant with a probiotic that specifically is made to prevent C diff. I can't remember the the name, maybe someone her remembers, It stats with Saccro... Bacillus... I think. Anyway. You've started, just be aware and if you have any suspect symptoms, act right away. I don't want to scare you. It's just that some antibiotics are known to be more likely to cause C diff whether you have a colon or not. And if you've never had it, I wish you never will!!
