US BOXED WARNINGS: ADDICTION, ABUSE AND MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL INGESTION; RISKS FROM CONCOMITANT USE WITH BENZODIAZEPINES OR OTHER CNS DEPRESSANTS; ULTRA-RAPID METABOLISM OF CODEINE AND OTHER RISK FACTORS FOR LIFE-THREATENING RESPIRATORY DEPRESSION IN CHILDREN; NEONATAL OPIOID WITHDRAWAL SYNDROME; INTERACTIONS WITH DRUGS AFFECTING CYP450 ISOENZYMES:
-Addiction, Abuse, and Misuse: Use of this drug exposes patients and other users to the risks of opioid addiction and misuse, which can lead to overdose and death. Assess each patient's risk prior to prescribing 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. Monitor for respiratory depression, especially during initiation or following a dose increase.
-Accidental Ingestion of/exposure to even one dose, especially by children, can result in a fatal overdose.
-Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing for 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.
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 CYP450 2D6 polymorphism. This drug 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 this drug 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 can result from prolonged maternal opioid use during pregnancy; it may be life-threatening if not recognized and treated; it should be managed according to protocols developed by neonatology experts. If opioid use is needed for a prolonged period in a pregnant woman, advise patient of the risk of neonatal opioid withdrawal syndrome and ensure appropriate treatment be available.
-Interactions with Drugs Affecting CYP450 Isoenzymes: The effects of concomitant use or discontinuation of CYP450 3A4 inducers/inhibitors or CYP450 2D6 inhibitors are complex; concomitant use requires careful consideration of the effects on the parent drug, codeine, and the active metabolite, morphine.
Safety and efficacy have not been established in patients younger than 18 years.
