Hello Welcome to HCM You had episode of diarrhea and was advised to take ofloxacin and bifilac. Ofloxacin is an antibiotic drug and it is a broadspectrum antibiotic. When given in combination with ornidazole it covers almost all enteric bacteria. You have finished the five day course and still having episodes of loose motion. The reason behind symptoms may be- - Some worm infection, so need to take antihelminthic drug like Albendazole is there. - If everything come normal and symptoms may persist even them. If symptoms persist or increase in severity in presence of stress then most likely the symptoms are occurring due to Irritable Bowel Syndrome. I would advise you to please visit a psychiatrist for expert opinion. Hope it helps you, thanks
