Fioricet is a combination medication commonly prescribed to relieve tension headaches and migraines. It contains three active ingredients: butalbital (a barbiturate), acetaminophen (a pain reliever and fever reducer), and caffeine. Each of these components serves a specific purpose in relieving headaches.
Butalbital is a central nervous system depressant and muscle relaxant, which can help reduce tension and muscle contraction in the head and neck.
Acetaminophen is a pain reliever and fever reducer that can alleviate headache pain.
Caffeine can constrict blood vessels in the brain, which may help reduce the intensity of migraines and tension headaches.
