The antipyretic effect of paracetamol dose attributes interaction on the heat-regulating center of the brain located on the thermoregulation part of the hypothalamus. It triggers the peripheral vasodilation and sweating glands. (2)

It is a non-steroidal anti-inflammatory drug as it inhibits cyclooxygenase pathways. Due to exert central action it alleviates symptoms of pain. It is a pronounced over-the-counter drug for treating pain.

It inhibits two isoforms COX-1 & COX-2 (cyclooxygenase)involved in prostaglandin synthesis. Prostaglandin elicits the pain sensation and inhibits cyclooxygenase in the peripheral layer of the tissues. Hence, it is prescribed for fever and chills treatment. (3)
