Applies to aspirin / butalbital / caffeine / codeine: oral capsule.

Important warnings This medicine can cause some serious health issues

Oral route (capsule)

Addiction, Abuse, and Misuse

Butalbital/aspirin/caffeine/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 codeine sulfate, and monitor all patients regularly for the development of these behaviors or conditions.

Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS)

: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 REMS for these products.

Under the requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to healthcare providers.

Healthcare providers are strongly encouraged to complete a REMS-compliant education program, counsel patients and/or their caregivers, with every prescription, on safe use, serious risks, storage, and disposal of these products, emphasize to patients and their caregivers the importance of reading the Medication Guide every time it is provided by their pharmacist, and consider other tools to improve patient, household, and community safety.

Life-Threatening Respiratory Depression

Serious, life-threatening, or fatal respiratory depression may occur with use of butalbital/aspirin/caffeine/codeine phosphate.

Monitor for respiratory depression, especially during initiation of butalbital/aspirin/caffeine/codeine phosphate or following a dose increase.

Accidental Ingestion

Accidental ingestion of even one dose of butalbital/aspirin/caffeine/codeine phosphate, especially by children, can result in a fatal overdose of butalbital/aspirin/caffeine/codeine phosphate.

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/aspirin/caffeine/codeine phosphate 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/aspirin/caffeine/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.

Avoid the use of butalbital/aspirin/caffeine/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

Neonatal Opioid Withdrawal Syndrome

Prolonged use of butalbital/aspirin/caffeine/codeine phosphate 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 CYP3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with codeine are complex.

Use of CYP3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with butalbital/aspirin/caffeine/codeine phosphate requires careful consideration of the effects on the parent drug, codeine, and the active metabolite, morphine.
