Thanks for writing to health care magic.
Self prescription may work some times but will be dangerous in certain scenarios.
So i request you to not to self prescribe.
The treatment in a case of fever
depends on the etiology.
Does he have any chills
Does he have a soar throat?
Does he have any vomiting
or loose stool?
does he have any burning urination or frequency of urination?
Reply in detail so that I can help you better.
Hope this helps.
