Thank you for your query on Healthcare Magic.
It seems like a viral illness.
You can give acetaminophen
in prescribed dose every 6 th hourly depending on the presence of fever
Tablet with 160 mg can be given to the child, but there should be a minimum 6 hours gap between two tablets.
Give plenty of oral fluids to maintain hydration of the child.
Consult the doctor for examination and for further evaluation.
Hope I have answered your query.
