What is the mechanism of action of Tylenol in fever reduction?

Answer 1

Acetaminophen belongs to a class of drugs called analgesics (pain relievers) and antipyretics (fever reducers). The exact mechanism of action of acetaminophen is not known. Acetaminophen relieves pain by elevating the pain threshold, that is, by requiring a greater amount of pain to develop before it is felt by a person. It reduces fever through its action on the heat-regulating center of the brain (ie. hypothalamus). Specifically, it tells the center to lower the body's temperature when the temperature is elevated.
