Hi, I've noticed after reading through many topics that many of you have been prescribed Flagyl and I wonder why. As far as I've been told by doctors Flagyl is an extremely strong antibiotic usually prescribed for severe bacterial infections , parasites, trichimosis and these types of problems. From my own experience with Flagyl please insist that your doctor have a stool culture taken before going on this drug(preferably a proper culture done through a hospital or reputable lab - they technician should give you three vials to return). I've had improper cultures taken and who wants to go through that experience more than necessary. I was given Flagyl about 7 years ago for what was probably travels D that I had while in Maui of all places. Anyway a culture was not tken before I took the drug so if the illness was not bacterial in nature it was useless. I got worse and wound up with too much yeast in my colon after finally having a cultre done and then given nizoral which worked great on yeast by the way & nizoral is not an antibiotic. This kicked off my IBS that I have dealt with since 1992. Just some advise from a fellow sufferer. Doctors often prescribe antibiotics without doing the proper tests and we know that antibiotics do not cure viral infedtions and then proceed to destroy the good flora in our system . These drugs are great when they are really need to fight bacteria but otherwise beware!
