Hi there, I think you have given him enough antipyretics recomended for the time frame and it would be best to give him cold
sponging and see if the fever
subsides. Wait for the result of blood test
and start definitive treatment and taking care of the cause will take care of the symptoms. If the fever doen't go down with coldsponging then on the advise of the pediatrician
you can give him injectable antipyretics. Do nt cover him up if he is not feeling cold and do sponge him forehead bpdy and armpits. This shouild help take care.
