Watery stool from yesterday ( 8-to 10 times ). Taken levofloxacin-ornidazole tablet ( Lcin-oz ), lactic acid bacillus cap & diphenoxylate HCl+ atropine sulphate tab on prescription by a doctor ( acute gastroenteritis) age 31 years. No improvement at all after taking four doses. Decided to take NORFLOX-TZ & ORS. Please suggest me should I stop taking prescribed medicaments & start taking NORFLOX-TZ tab ( I have no rrena or kidney problem )
