welcome to healthcare magic. For loose stools, off course you can take metronidazole
, but i would say ofloxacin
200 mg twice daily is a better one. If very bad can even take injectable one. Remember to rehydrate yourself, preferably orally with ORS
solutions, coconut water, juices etc. But if loose stools are agitated even by that , better keep youself nill by mouth and get intravenous drips like normal saline / ringer lactate.Mind you, rehydration is very mandatory. And keep a tag if you are still passing urine, b'coz if not, then your kidney
might get affected, rush to hosp.
