Thank you for your query on Healthcare Magic.Zanocin
and it usually prescribed in bacterial diarrhea
But there are many causes for diarrhea like virus, entameba, and bacteria.
Viral diarrhea doesn't require any antibiotic.
Zanocin is an antibiotic and it is a prescribed drug, so I advise you not to give this to the child without a doctor prescription.
General medication when the child gets diarrhea is oral rehydration solutions (ORS), oral probiotic
, and zinc supplementation.
Hope I have answered your query.
