Norflox is an antibiotic useful in urinary infections and timidazole is useful in gut infections.for vomitting and diarrhoea usually we prescribe another group of medicines but not norflox-tz. omez-D is useful for vomitting and antibiotic induced acidity in the gut.for diarrhoea is it is loose watery stool loperamide is required.for bloody stools timidazole is required.in kitchen one simple remedy is there for only diarrhoea-grinding fried poppy seeds and taking the paste with curd rice.But if stomach pain is there,or vomittings are there,blood is there in stools it is better you consult a qualified physician than taking OTC drugs like this because injudicious use of these will result in drug resistance and when you really require these may not work and also you have to suffer from side effects of unnecessary medications.
