  • Paracetamol blocks the Cyclo-oxygenase (COX) enzymes (natural enzymes of body) which further blocks prostaglandins secretion, prostaglandins are responsible for redness, pain and swelling at the site of injury. Therefore, blocking COX blocks prostaglandins as well, leading to pain cessation, increased blood flow through skin and loss of heat and sweating which lowers the fever.
