Fioricet Cautions and Warnings

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.

Liver Damage While taking Acetaminophen

The safety dosage is 3000mg per day.  Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed 4000 milligrams per day, and often involve more than one acetaminophen-containing product.  According to the FDA, in the United States there were “56,000 emergency room visits, 26,000 hospitalizations, and 458 deaths per year related to acetaminophen-associated overdoses during the 1990s. Within these estimates, unintentional acetaminophen overdose accounted for nearly 25% of the emergency department visits, 10% of the hospitalizations, and 25% of the deaths.” [1]
