Thanks for the query
High grade fever
with throat pain and difficulty in swallowing suggests inflammation of tonsils or throat.
is an antiinflammatory and antipyratic, that's why there is no fever. The problem is not due to Meftal. There is high chance of infection so give him Ampiclox
syrup( 250 mg/5 ml) 7.5 ml 6 hrly for 7 days. Avoid cold drinks, if possible give him warm water.
If condition worsens take him to the pediatrician
for proper clinical evaluation.
I hope this answers your query well
Wish you and your family good health
