Thank you for your query on Healthcare Magic.
The loose motions may be due to antibiotic induced or some times due to primary infection which is known as parenteral diarrhea
As the WBC count
is high it is suggestive of some bacterial infection and this should be treated with antibiotics as advised.
Loose motions are not an indication for the stop of antibiotic.
Loose motions can be treated by giving oral probiotic
like saccharomyces or lactobacillus
sachets once or twice daily with prescription.
I advise you to consult your doctor for re evaluation and for treatment.
Hope I have answered your query.
