For the Consumer

Oral route (Capsule)
Addiction, Abuse, and Misuse
Acetaminophen/caffeine/dihydrocodeine bitartrate 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 acetaminophen / caffeine / dihydrocodeine bitartrate, 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 acetaminophen / caffeine / dihydrocodeine bitartrate. Monitor for respiratory depression, especially during initiation of acetaminophen / caffeine / dihydrocodeine bitartrate or following a dose increase.
Accidental ingestion of even one dose of acetaminophen / caffeine / dihydrocodeine bitartrate, especially by children, can result in a fatal overdose of acetaminophen / caffeine / dihydrocodeine bitartrate.
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. Acetaminophen / caffeine / dihydrocodeine bitartrate 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 acetaminophen / caffeine / dihydrocodeine bitartrate 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 acetaminophen / caffeine / dihydrocodeine bitartrate 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 acetaminophen / caffeine / dihydrocodeine bitartrate requires careful consideration of the effects on the parent drug, codeine, and the active metabolite, morphine.Hepatotoxicity: 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.
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 acetaminophen / caffeine / dihydrocodeine bitartrate 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.
