Hello and welcome to HCM
a good antipyretic
drug to be used in pediatrics. It help in reducing the fever
very effectively. In addition to this if fever does't go down than you can also use Paracetamol
syrup and cold sponging.
This will help you to reduce the temperature. Keep your baby warm and protect him from changing climate and change his wet clothes regularly.
In my opinion if fever still persist for another day than give him a course of antibiotic by consulting your doctor.
