Acetaminophen is a non-narcotic analgesic (pain reliever) and antipyretic (fever reducer).
Acetaminophen works by elevating the threshold to pain, that is, in order for pain to be felt, greater stimulation of the nerves responsible for the sensation of pain is necessary. It reduces fever through its action on the temperature-regulating center of the brain. It contains a narcotic pain reliever (hydrocodone) and a non-narcotic pain reliever (acetaminophen).
