Depends on the age of the child too.
I'm a bit more cautious with wee little ones and high fever. I gave a single does of Ibuprofen to my1 yo when her fever spiked to 102 and she was very fussy.
My bigger kids I mostly watch behavior. If they are uncomfortable headaches, body aches, chills, ect I will medicate for that. Otherwise the fever runs its course.
