I have IBS on the loose side which can be managed with loperamide,although the dose is on the high side.But I've been on an Antibiotic for a urine infection and it's actually helped slow my bowel down,even a touch of constipation at times and only 1 or 2 BMs a day allowing less doses of loperamide.I still have bloating and cramps etc so it's not a cure or anything but why does this sort of thing happen?And what is it in the Antibiotics that slows the bowel down?Could it not be used in IBS medicines?
