How it controls fever?

Normal body temperature is 98.6 F, which is regulated by hypothalamus (brain)
When infection occurs, there is increase secretion of prostaglandin
Which causes disturbance in hypothalamus & due to that temperature increases called fever
After taking ibuprofen, this medicine blocks the synthesis of prostaglandin
So, for period of time hypothalamus works well & temperature decreases.


This way Ibuprofen decreases the temperature for short period of time. Other medicines will control the infection.
