Addiction, Abuse, and Misuse
- Risk of addiction, abuse, and misuse, which can lead to overdosage and death.290 291 303 305 Assess each patient’s risk for addiction, abuse, and misuse before prescribing the drug; monitor all patients regularly for development of these behaviors or conditions.290 291 303 305 (See Addiction, Abuse, and Misuse under Cautions.)
- Serious, life-threatening, or fatal respiratory depression may occur.290 291 303 305 Monitor for respiratory depression, especially during initiation of therapy and following dosage increases.290 291 303 305 (See Respiratory Depression under Cautions.)
- Patients must swallow extended-release tablets whole to avoid exposure to a potentially fatal dose.290 305
- Accidental ingestion of even 1 dose, especially by a child, can result in a fatal overdose.290 291 303 305
Neonatal Opiate Withdrawal
- Prolonged maternal use of opiates during pregnancy can result in neonatal withdrawal syndrome, which may be life-threatening if not recognized and treated.290 291 303 305 Advise women who require such therapy during pregnancy of this risk and ensure appropriate treatment will be available.290 291 303 305 (See Pregnancy under Cautions.)
- Initiation of CYP3A4 inhibitors or discontinuance of CYP3A4 inducers can result in fatal oxycodone overdosage.290 291 303
Medication Errors with Oral Solutions
- Potential for medication errors resulting in inadvertent overdosage and death due to confusion between mg and mL or between oxycodone hydrochloride solution (5 mg/5 mL) and oxycodone hydrochloride oral concentrate solution (100 mg/5 mL).299 304 Take care to ensure that the correct dose is communicated and dispensed.299 304
- Use oral concentrate solution only in opiate-tolerant patients.304
- Keep oral solutions out of the reach of children.299 304 If accidental ingestion occurs, seek immediate medical attention.299 304
Concomitant Use with Benzodiazepines or Other CNS Depressants
- Concomitant use of opiate agonists with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death.416 417 418 700 701 702 703
- Reserve concomitant use of opiate analgesics and benzodiazepines or other CNS depressants for patients in whom alternative treatment options are inadequate; use lowest effective dosages and shortest possible duration of concomitant therapy and monitor closely for respiratory depression and sedation.700 703 (See Specific Drugs under Interactions.)
FDA approved a REMS for oxycodone to ensure that the benefits outweigh the risk. The REMS may apply to one or more preparations of oxycodone and consists of the following: medication guide and elements to assure safe use. See the FDA REMS page ([Web]).
