Also, it is used to relieve headaches, migraine, toothache, period pain, back pain, muscle pain and rheumatic pains. Pain and fever are caused by the activation of pain receptors due to the release of certain natural chemicals in the body, like prostaglandin.
Acetaminophen contains acetaminophen that works by inhibiting the production of certain chemical messengers in the brain known as prostaglandins. Thus, reducing pain. Also, Acetaminophen affects an area of the brain that regulates body temperature known as the hypothalamic heat-regulating centre. Thereby it reduces fever.
