Clinical summary
Indications and usage 1 INDICATIONS AND USAGE BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE is indicated for the management of the symptom complex of tension (or muscle contraction) headache, when non-opioid analgesic and alternative treatments are inadequate. BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE is a combination of butalbital, a barbiturate, aspirin, a nonsteroidal anti-inflammatory drug, caffeine, a methylxanthine, and codeine phosphate, an opioid agonist, and is indicated for the management of the symptom complex of tension (or muscle contraction) headache, when other non-opioid analgesics and alternative treatments are inadequate. Limitations of Use Because of the risks of addiction, abuse, misuse, overdose, and death, which can occur at any dosage or duration and persist over the course of therapy, reserve opioid analgesics, including BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE for use in patients for whom alternative treatment options are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain ( 1 , 5.1 ). BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE should not be used for an extended period of time unless the pain remains severe enough to require an opioid analgesic and for which alternative treatment options continue to be inadequate. Limitations of Use Because of the risks of addiction, abuse, misuse, overdose, and death, which can occur at any dosage or duration and persist over the course of therapy [see Warnings and Precautions ( 5.1 ) ] , reserve opioid analgesics, including BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE for use in patients for whom alternative treatment options are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE should not be used for an extended period of time unless the pain remains severe enough to require an opioid analgesic and for which alternative treatment options continue to be inadequate. Dosage and administration 2 DOSAGE AND ADMINISTRATION Periodically reassess patients receiving BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE to evaluate the continued need for opioid analgesics to maintain pain control, for the signs or symptoms of adverse reactions, and for the development of addiction, abuse, or misuse. Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals. Reserve titration to higher doses of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks. ( 2.1 , 5 ) Initiate the dosing regimen for each patient individually, taking into account the patient's underlying cause and severity of pain, prior analgesic treatment and response, and risk factors for addiction, abuse, and misuse ( 2.1 , 5.1 ) Discuss availability of naloxone with the patient and caregiver and assess each patient's need for access to naloxone, both when initiating and renewing treatment with BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE. Consider prescribing naloxone based on the patient's risk factors for overdose. ( 2.2 , 5.1 , 5.2 , 5.3 ) Discuss opioid overdose reversal agents and options for acquiring them with the patient and/or caregiver, both when initiating and renewing treatment with BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE, especially if the patient has additional risk factors for overdose, or close contacts at risk for exposure and overdose. ( 2.2 , 5.1 , 5.2 , 5.3 ) BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE should be prescribed only by healthcare professionals who are knowledgeable about the use of opioids and how to mitigate the associated risks. ( 2.1 ) Many acute pain conditions (e.g., the pain that occurs with a number of surgical procedures or acute musculoskeletal injuries) require no more than a few days of an opioid analgesic. Clinical guidelines on opioid prescribing for some acute pain conditions are available. ( 2.1 ) Respiratory depression can occur at any time during opioid therapy, especially when initiating and following dosage increases with BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE. Consider this risk when selecting an initial dose and when making dose adjustments. ( 2.1 , 5.2 ) Initiate treatment with one or two capsules every 4 hours as needed for pain and at the lowest dose necessary to achieve adequate analgesia. Titrate the dose based upon the individual patient's response to their initial dose of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE. Total daily dosage should not exceed 6 capsules. ( 2 , 5 ) Do not rapidly reduce or abruptly discontinue BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE in a physically dependent patient because rapid reduction or abrupt discontinuation of opioid analgesics has
Boxed Warning
WARNING: SERIOUS AND LIFE-THREATENING RISKS FROM USE OF BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE. WARNING: SERIOUS AND LIFE-THREATENING RISKS FROM USE OF BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE See full prescribing information for complete boxed warning. BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE exposes users to the risks of addiction, abuse, and misuse, which can lead to overdose and death. Assess patient's risk before prescribing and monitor regularly for these behaviors and conditions. ( 5.1 ) Serious, life-threatening, or fatal respiratory depression may occur. Monitor closely, especially upon initiation or following a dose increase. ( 5.2 ) Accidental ingestion of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE, especially by children, can result in fatal overdose. ( 5.2 ) Concomitant use of opioids or a barbiturate with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing for use in patients for whom alternative treatment options are inadequate; limit dosages and durations to the minimum required; and follow patients for signs and symptoms of respiratory depression and sedation. ( 5.3 , 5.9 , 7 ) Advise pregnant women using opioids for an extended period of time of the risk of Neonatal Opioid Withdrawal Syndrome, which may be life-threatening if not recognized and treated. Ensure that management by neonatology experts will be available at delivery. ( 5.4 ) To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse and misuse, the Food and Drug Administration (FDA) has required a Risk Evaluation and Mitigation Strategy (REMS) for these products ( 5.5 ) Life-threatening respiratory depression and death have occurred in children who received codeine; most cases followed tonsillectomy and/or adenoidectomy, and many of the children had evidence of being an ultra-rapid metabolizer of codeine due to a CYP2D6 polymorphism. ( 5.6 ) BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE is contraindicated in children younger than 12 years of age and in children younger than 18 years of age following tonsillectomy and/or adenoidectomy ( 4 ). Avoid the use of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE in adolescents 12 to 18 years of age who have other risk factors that may increase their sensitivity to the respiratory depressant effects of codeine. 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, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE requires careful consideration of the effects on codeine, and the active metabolite, morphine. ( 5.7 , 5.9 , 7 ) Addiction, Abuse, and Misuse Because the use of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE exposes 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 and reassess all patients regularly for the development of these behaviors and conditions [see Warnings and Precautions ( 5.1 ) ]. Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression may occur with use of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE, especially during initiation or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE are essential [see Warnings and Precautions ( 5.2 )] Accidental Ingestion Accidental ingestion of even one dose of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE, especially by children, can result in a fatal overdose of aspirin, butalbital, caffeine and codeine phosphate [see Warnings and Precautions ( 5.2 )]. Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. [see Warnings and Precautions ( 5.3 , 5.9 ), Drug Interactions ( 7 )]. Neonatal Opioid Withdrawal Syndrome (NOWS) Advise pregnant women using opioids for an extended period of time of the risk of Neonatal Opioid Withdrawal Syndrome, which may be life-threatening if not recognized and treated. Ensure that management by neonatology experts will be available at delivery [see Warnings and Precautions ( 5.4 )]. Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS) Healthcare providers are strongly encouraged to complete a REMScompliant education program and to counsel patients and caregivers on serious risks, safe use, and the importance of reading the Medication Guide with each prescription [see Warnings and Precautions ( 5.5 )]. 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. [see Warnings and Precautions ( 5.6 )]. BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE is contraindicated in children younger than 12 years of age and in children younger than 18 years of age following tonsillectomy and/or adenoidectomy [see Contraindications ( 4 )]. Avoid the use of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE in adolescents 12 to 18 years of age who have other risk factors that may increase their sensitivity to the respiratory depressant effects of codeine. Interactions with Drugs 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, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE requires careful consideration of the effects on codeine, and the active metabolite, morphine [see Warnings and Precautions ( 5.7 , 5.9 ), Drug Interactions ( 7 )].
Monitoring
- • 5 WARNINGS AND PRECAUTIONS Opioid-Induced Hyperalgesia and Allodynia : Opioid-Induced Hyperalgesia (OIH) occurs when an opioid analgesic paradoxically causes an increase in pain, or an increase in sensitivity to pain.
- • If OIH is suspected, carefully consider appropriately decreasing the dose of the current opioid analgesic, or opioid rotation.
- • ( 5.8 ) Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients : Regularly evaluate, particularly during initiation and titration.
- • ( 5.9 ) Adrenal Insufficiency : If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off the opioid.
Interaction Notes
- • 7 DRUG INTERACTIONS Table 2 includes clinically significant drug interactions with BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE.
- • Table 2: Clinically Significant Drug Interactions With BUTALBITAL, ASPIRIN, CAFFEINE And CODEINE PHOSPHATE Inhibitors of CYP3A4 Clinical Impact: The concomitant use of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE with CYP3A4 inhibitors may result in an increase in codeine plasma concentrations with subsequently greater metabolism by cytochrome CYP2D6, resulting in greater morphine levels, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression, particularly when an inhibitor is added after a stable dose of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE is achieved.
- • After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, it may result in lower codeine levels, greater norcodeine levels, and less metabolism via 2D6 with resultant lower morphine levels [see Clinical Pharmacology ( 12.3 )] , resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to codeine.
- • Intervention: If concomitant use with a CYP3A4 inhibitor is necessary, consider dosage reduction of BUTALBITAL, ASPIRIN, CAFFEINE and CODEINE PHOSPHATE until stable drug effects are achieved.
