I am 29 years old and I am suffering from digestion issue, stomach pain and noise with diarrhea for one week. I have consulted doctor last thursday who have prescribed medicines meva-c, vizylac rich and rantac od 300. But my diarrhea and stomach noise still persist. I suspect it to be a stomach infection resulting from restaurant food. Can I take antibiotics like norflox/o2 along with these medicines?
