Addiction, Abuse, and Misuse:Butalbital, acetaminophen, caffeine, and codeine phosphate capsules expose patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient's risk prior to prescribing butalbital, acetaminophen, caffeine, and codeine phosphate capsules, and monitor all patients regularly for the development of these behaviors or conditions.Life-Threatening Respiratory Depression:Serious, life-threatening, or fatal respiratory depression may occur with use of butalbital, acetaminophen, caffeine, and codeine phosphate capsules. Monitor for respiratory depression, especially during initiation of butalbital, acetaminophen, caffeine, and codeine phosphate capsules or following a dose increase.Accidental Ingestion:Accidental ingestion of even one dose of butalbital, acetaminophen, caffeine, and codeine phosphate capsules, especially by children, can result in a fatal overdose of butalbital, acetaminophen, caffeine, and codeine phosphate capsules.Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants:Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of butalbital, acetaminophen, caffeine, and codeine phosphate capsules and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.Ultra-Rapid Metabolism of Codeine and Other Risk Factors for Life-Threatening Respiratory Depression in Children:Life-threatening respiratory depression and death have occurred in children who received codeine. Most of the reported cases occurred following tonsillectomy and/or adenoidectomy, and many of the children had evidence of being an ultra-rapid metabolizer of codeine due to a CYP2D6 polymorphism. butalbital, acetaminophen, caffeine, and codeine phosphate capsules are contraindicated in children younger than 12 years of age and in children younger than 18 years of age following tonsillectomy and/or adenoidectomy. Avoid the use of butalbital, acetaminophen, caffeine, and codeine phosphate capsules in adolescents 12 to 18 years of age who have other risk factors that may increase their sensitivity to the respiratory depressant effects of codeineNeonatal Opioid Withdrawal Syndrome:Prolonged use of butalbital, acetaminophen, caffeine, and codeine phosphate capsules during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.Interactions with Drug Affecting Cytochrome P450 Isoenzymes:The effects of concomitant use or discontinuation of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with codeine are complex. Use of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with butalbital, acetaminophen, caffeine, and codeine phosphate capsules requires careful consideration of the effects on the parent drug, codeine, and the active metabolite, morphine.HepatotoxicityButalbital, Acetaminophen, Caffeine, and Codeine Phosphate Capsules contain acetaminophen. 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 4,000 milligrams per day, and often involve more than one acetaminophen-containing product

Uses For This Medicine
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. They 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 or in large doses, it may become habit-forming, causing mental or physical dependence. Physical dependence may lead to withdrawal side effects when you suddenly stop taking the medicine. In patients who get headaches, the first symptom of withdrawal may be new (rebound) headaches.
Butalbital, acetaminophen, caffeine, and codeine is available only with your doctor's prescription.
Before Using This Medicine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For butalbital, acetaminophen, caffeine, and codeine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to butalbital, acetaminophen, caffeine, and codeine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
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. It should not be used in children younger than 12 years of age. Safety and efficacy have not been established.
Butalbital, acetaminophen, caffeine, and codeine should not be used to relieve pain after surgery removal of tonsils 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 liver, kidney, heart, or lung problems, which may require caution and an adjustment in the dose for patients receiving butalbital, acetaminophen, caffeine, and codeine.
Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using butalbital, acetaminophen, caffeine, and codeine.

Proper Use of This Medicine
Take butalbital, acetaminophen, caffeine, and codeine 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 butalbital, acetaminophen, caffeine, and codeine 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.
Butalbital, acetaminophen, caffeine, and codeine should come with a Medication Guide. Read and follow these instructions carefully. Ask your doctor if you have any questions.
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.
Butalbital, acetaminophen, caffeine, and codeine will relieve a headache best if you take it as soon as the headache begins. If you get warning signs of a migraine, take butalbital, acetaminophen, caffeine, and codeine 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 other medicines, 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 butalbital, acetaminophen, caffeine, and codeine 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 butalbital, acetaminophen, caffeine, and codeine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Precautions While Using This Medicine
It is very important that your doctor check your progress while you are taking butalbital, acetaminophen, caffeine, and codeine, especially within the first 24 to 72 hours of treatment. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it. Blood tests may be needed to check for unwanted effects.
Do not use butalbital, acetaminophen, caffeine, and codeine if you are using or have used an MAO inhibitor (MAOI) such as isocarboxazid [Marplan®], linezolid [Zyvox®], phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]) within the past 14 days.
If you think you or someone else may have taken an overdose of butalbital, acetaminophen, caffeine, and codeine, get emergency help at once. Signs of an overdose include dark urine, difficult or troubled breathing, irregular, fast or slow, or shallow breathing, nausea or vomiting, pain in the upper stomach, pale or blue lips, fingernails, or skin, pinpoint pupils of the eyes, or yellow eyes or skin.
Butalbital, acetaminophen, caffeine, and codeine will add to the effects of alcohol and other CNS depressants (medicines that can make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicine, other prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. Also, there may be a greater risk of liver damage if you drink 3 or more alcoholic beverages while you are taking acetaminophen. Do not drink alcoholic beverages, and check with your doctor before taking any of these medicines while you are using butalbital, acetaminophen, caffeine, and codeine.
Dizziness, lightheadedness, or fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help. Also, lying down for a while may relieve dizziness or lightheadedness. If this problem continues or gets worse, check with your doctor right away.
Butalbital, acetaminophen, caffeine, and codeine may make you dizzy, drowsy, confused, or disoriented. Do not drive or do anything else that could be dangerous until you know how butalbital, acetaminophen, caffeine, and codeine affects you.
Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.
Butalbital, acetaminophen, caffeine, and codeine may cause serious allergic reactions, including anaphylaxis or certain skin conditions (eg, Stevens-Johnson syndrome). These reactions can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, itching, blistering, peeling, or loosening of the skin, fever or chills, trouble breathing or swallowing, or any swelling of your hands, face, mouth, or throat while you are using butalbital, acetaminophen, caffeine, and codeine.
Check the labels of all nonprescription (over-the-counter [OTC]) or prescription medicines you now take. If any contain a barbiturate, acetaminophen, caffeine, or codeine, check with your doctor. Taking them together with butalbital, acetaminophen, caffeine, and codeine may cause an overdose.
Using butalbital, acetaminophen, caffeine, and codeine while you are pregnant may cause serious unwanted effects, including neonatal withdrawal syndrome in your newborn baby. Tell your doctor right away if you think you are pregnant or if you plan to become pregnant while using butalbital, acetaminophen, caffeine, and codeine.
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. Do not give butalbital, acetaminophen, caffeine, and codeine to:
- Children younger than 12 years of age.
- Children younger than 18 years of age who have had surgery removal of tonsils or adenoids.
- Children 12 to 18 years of age who have a high risk for breathing problems (eg, obstructive sleep apnea, obesity, lung disease).
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 butalbital, acetaminophen, caffeine, and codeine:
- Talk to your doctor if you have any questions about taking codeine or about how butalbital, acetaminophen, caffeine, and codeine may affect your baby.
- Call your doctor if you become extremely tired and have difficulty caring for your baby.
- Your baby should generally nurse every 2 to 3 hours and should not sleep for more than 4 hours at a time.
- Check with your doctor or hospital emergency room right away if your baby shows signs of increased sleepiness (more than usual), difficulty breastfeeding, difficulty breathing, or limpness. These may be symptoms of an overdose and need immediate medical attention.
Butalbital, acetaminophen, caffeine, and codeine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.
Using narcotics for a long time can cause severe constipation. To prevent this, your doctor may direct you to take laxatives, drink a lot of fluids, or increase the amount of fiber in your diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.
Before you have any medical tests, tell the medical doctor in charge that you are taking butalbital, acetaminophen, caffeine, and codeine. The results of some tests may be affected by butalbital, acetaminophen, caffeine, and codeine.
Before having any kind of surgery (including dental surgery) or emergency treatment, tell the medical doctor or dentist in charge that you are taking butalbital, acetaminophen, caffeine, and codeine. Serious side effects can occur if your doctor or dentist gives you certain medicines without knowing that you have been taking butalbital or codeine.
Check with your doctor right away if you have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be symptoms of a serious condition called serotonin syndrome. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.
Using too much of butalbital, acetaminophen, caffeine, and codeine may cause infertility (unable to have children). Talk with your doctor before using butalbital, acetaminophen, caffeine, and codeine if you plan to have children.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
