Hi Sally Jane & Trac,This is what many MDs do--they Rx flagyl(metronidazole) without countering the bacterial die-off with multi-strain high quality probiotics. (you should always take a probiotic 3-4 hours after an anti, or one hour before the anti.)ie--"Currently under investigation are antibiotics such as ciprofloxacin, metronidazole, and doxycycline, which can treat postinfectious IBS, a disorder believed to be caused by alterations in intestinal microflora."
http://www.emedmag.com/html/pre/gic/consults/041501.asp >>But many people here & elsewhere have a worsening effect from flagyl because of having very imbalanced gut flora before the flagyl was given.Here's some more info on bad reactions to flagyl/metronidazole:"A second study in the European Journal of Gastroenterology and Hepatology shows that taking metronidazole kills the bacteria that cause the gas, and it takes around 50 days for the bacteria to return, so if you do not avoid refined carbohydrates, expect the irritable bowel syndrome to recur (2). "
http://www.drmirkin.com/morehealth/9095.html Irritable Bowel SyndromeHunter and his colleagues have studied patients with the irritable bowel syndrome in whom diarrhea, cramps and specific food intol- erances are major symptoms(24). They have found abnormal fecal flora to be a consistent finding, with a decrease in the ratio of anaer- obes to aerobes, apparently due to a deficiency of anaerobic flora (25,26). Previous exposure to antibiotics, metronidazole in particular, was associated with the development of this disorder(27).
