Caffeine, butalbital, and Acetaminophen combine to form Fioricet. Caffeine functions to stimulate the Central Nervous System, Butalbital functions as a sedative, it helps to ease anxiety and stress, and Acetaminophen helps to relieve fever and pain. Fioricet helps to treat tension headaches that happen due to muscle contraction.

 

How does Fioricet work?

 

Stress causes the muscles of blood vessels in the brain and neck to contract; this restricts the flow of blood to the brain. Fioricet helps to relax these contractions, which helps to dilate the blood vessels and improve the blood flow, and this helps to prevent headaches.
