Fiorinal is a combination analgesic medication consisting of acetylsalicylic acid, the barbiturate butalbital and caffeine. Some formulations also contain the opioid codeine. It is used to treat tension headaches and migraines. The mechanism of action is not well understood. Since butalbital is habit-forming, using fiorinal daily can lead to dependency.
