The medication Fioricet is a pain reliever used to treat tension headaches. Fioricet consists of three medication formulations known as acetaminophen, caffeine, and butalbital. The following medication combinations work interconnected to each other, where acetaminophen decreases the pain from headache, caffeine increases the effects of acetaminophen, and butalbital acts on the central nervous system by slowing down the brain functioning to provide sedation and relaxation. Apart from being a painkiller, Fioricet also helps in reducing fever and acts as a cough suppressant for many people.
