Fioricet contains a combination of acetaminophen, butalbital, and caffeine. Butalbital is a short to intermediate-acting barbiturate and is habit-forming and potentially abusable. Consequently, the extended use of this product is not recommended.
Acetaminophen is used to relieve mild to moderate pain from headaches, muscle aches, menstrual periods, colds and sore throats, toothaches, backaches, and reactions to vaccinations (shots), and to reduce fever. Caffeine is a methylxanthine similar to theophylline and theobromine. While caffeine is used for stimulant and mood-elevating effects in drinks such as coffee, it also has been used to treat neonatal apnea and headaches in combination with other analgesics.
