My 6 year son is having fever and cough. Fever is going down with fever medicine but occurring again after 6 hours How long it takes to break fever without medicine

A. See the fever should subside maximum within the time of 72 hours once you start giving medicine and if it doesn’t subside by the time of 72 hours then in that case it is advisable to go for further assistance as it is not considered as a normal fever it could be viral or any other category of fever can be seen
