How does it work?

Acetaminophen belongs to the analgesics (pain relievers) and antipyretics pharmacological classes (fever reducers). Acetaminophen's specific method of action is unknown. 

Prostaglandin production in the brain may be reduced by this medication. Prostaglandins are inflammatory and swelling-causing substances. Acetaminophen alleviates pain by raising the pain threshold, which means that a person must experience more pain before feeling it. 

It works by reducing fever by affecting the brain's heat-regulating region. When the body's temperature rises, it instructs the center to lower the body's temperature (Graham, G.G. and Scott, K.F., 2005. Mechanism of action of paracetamol).
