Thanks for the query
Apart from using paracetamol
you can also give Meftal-p( mefenemic acid) in a dose of half of paracetamol( 125 mg). Also do tepid( lukewarm water) sponging that will help in reduction of temp.
Give him Syp. Augmentin
Duo 5 ml thrice a day for throat infection
. Avoid cold items in feed.
Even if high grade fever
is persisting then consult a pediatitrician for allopathic treatment.
I hope this answers your query well
Wish you and your family good health
