Each dose of Fioricet contains 300 to 325 mg of acetaminophen. Many other medications also contain acetaminophen. Your upper daily limit from all sources is 3,000 mg per day.
Taking too much acetaminophen (found in this combination preparation) can cause liver damage, sometimes serious enough to require liver transplantation or cause death. Be aware that you should not take more than 4,000 mg of acetaminophen per day. You might accidentally take too much acetaminophen if you do not follow the directions on the prescription or package label carefully, or if you take more than one product that contains acetaminophen. If you need to take more than one product that contains acetaminophen, it may be difficult for you to calculate the total amount of acetaminophen you are taking. Ask your doctor or pharmacist to help you. Tell your doctor if you have or have ever had liver disease.
