Thank you for your query.
You need to complete the course of amoxicillin
and add some decongestant/cough
syrup and paracetamol/acetaminophen
to control the fever
. In case there is no improvement then a revisit to the doctor is warranted.
I hope I have answered your query to your satisfaction.
Wishing your son an early recovery.
