Liver failure, sometimes associated with liver transplant or fatalities, has occurred with acetaminophen use. These cases of liver injury were often associated with the use of more than one acetaminophen-based product and with total daily acetaminophen doses exceeding 4000 mg. Life-threatening or fatal respiratory depression has occurred with codeine administration following tonsillectomy or adenoidectomy in children with evidence of a CYP2D6 polymorphism that causes ultrarapid codeine metabolism .
Butalbital, acetaminophen, caffeine, and codeine combination is used to relieve symptoms of tension (or muscle contraction) headaches. Extended and repeated use of this product is not recommended.
Butalbital belongs to the group of medicines called barbiturates. Barbiturates act in the central nervous system (CNS) to produce their effects.
Acetaminophen is used to relieve pain and reduce fever in patients. It does not become habit-forming when taken for a long time. But acetaminophen may cause other unwanted effects when taken in large doses, including serious liver damage. Although rare, use of acetaminophen has been reported to lead to liver transplantation and death, usually at high doses and when multiple acetaminophen-containing products have been used.
Caffeine is a CNS stimulant that is used with pain relievers to increase their effect. It has also been used for migraine headaches. Codeine belongs to the group of medicine called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain.
When butalbital or codeine is used for a long time, it may become habit-forming, causing mental or physical dependence) when it is used for a long time or in large doses. Physical dependence may lead to withdrawal side effects when you stop taking the medicine. In patients who get headaches, the first symptom of withdrawal may be new (rebound) headaches.

Appropriate studies have not been performed on the relationship of age to the effects of butalbital, acetaminophen, caffeine, and codeine combination in the pediatric population. Safety and efficacy have not been established.
Fioricet® with codeine should not be used to relieve pain after surgery removal of tonsils and/or adenoids in any children. Severe breathing problems and deaths have been reported in some children who received codeine after tonsil or adenoid surgery.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of butalbital, acetaminophen, caffeine, and codeine combination in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving this medicine.

Other medical problems
The presence of other medical problems may affect the use of this medicine. Make sure you tell your doctor if you have any other medical problems, especially:
Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. If too much of this medicine is taken for a long time, it may become habit-forming and cause mental or physical dependence. Also, large amounts of acetaminophen may cause liver damage if taken for a long time.
Carefully check the labels of all other medicines you are using, because they may also contain acetaminophen. It is not safe to use more than 4 grams (4,000 milligrams) of acetaminophen in one day (24 hours), as this may increase the risk for serious liver problems.
This medicine will relieve a headache best if you take it as soon as the headache begins. If you get warning signs of a migraine, take this medicine as soon as you are sure that the migraine is coming. This may even stop the headache pain from occurring. Lying down in a quiet, dark room for a while after taking the medicine also helps to relieve headaches.
People who get a lot of headaches may need to take a different medicine to help prevent headaches. It is important that you follow your doctor's directions about taking the other medicine, even if your headaches continue to occur. Headache-preventing medicines may take several weeks to start working. Even after they do start working, your headaches may not go away completely. However, your headaches should occur less often, and they should be less severe and easier to relieve than before. This will reduce the amount of headache relievers that you need. If you do not notice any improvement after several weeks of headache-preventing treatment, check with your doctor.
The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

Codeine is changed to morphine in the body. Some people change codeine to morphine more quickly than others. These individuals are called "ultra-rapid metabolizers of codeine".Contact your doctor immediately if you experience extreme sleepiness, confusion, or shallow breathing. These symptoms may indicate that you are an "ultra-rapid metabolizer of codeine". As a result, there is too much morphine in the body and more side effects of morphine than usual. Children may be especially sensitive to this effect.
If a nursing mother is an ultra-rapid metabolizer of codeine, it could lead to a morphine overdose in the nursing baby and cause very serious side effects.
For nursing mothers taking this medicine:
Acetaminophen may cause serious allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention.
