Thank you for your query on Healthcare Magic.
Your child seems having gastroenteritis
due to a bacteria or a virus.
The stool is showing pus cells which is suggestive of infection.
like cefixime or colistin can be given instead of injections.
But before starting stool to be given for culture and sensitivity to know the organism and its sensitivity to the antibiotics.
Hydration to be maintained by giving sips of oral rehydration fluids like Pedialyte
and zinc can be added after the doctor consultation.
Therefore I advise you to consult your Pediatrician
for the prescription of medication on oral form empirically and once the stool culture report comes, the modification can be done depending on the report.
Hope I have answered your query.
