Safety & Warnings
BLACK BOX WARNING
Addiction, Abuse, and Misuse: Oxycodone and Acetaminophen Tablets expose patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patientβs risk prior to prescribing Oxycodone and Acetaminophen Tablets, and monitor all patients regularly for the development of these behaviors and conditions.
Respiratory Depression: Serious, life-threatening, or fatal respiratory depression may occur. Monitor for respiratory depression, especially during initiation of Oxycodone and Acetaminophen Tablets or following a dose increase.
Accidental Ingestion: Accidental ingestion of even one dose of Oxycodone and Acetaminophen Tablets, especially by children, can result in a fatal overdose of oxycodone.
Neonatal Opioid Withdrawal Syndrome: Prolonged use of Oxycodone and Acetaminophen Tablets 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.
CYP3A4 Interaction: The concomitant use of Oxycodone and Acetaminophen Tablets with all cytochrome P450 3A4 inhibitors may result in an increase in oxycodone plasma concentrations, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression. In addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an increase in oxycodone plasma concentration. Monitor patients receiving Oxycodone and Acetaminophen Tablets and any CYP3A4 inhibitor or inducer.
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 4000 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 central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs 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.
Side Effects
Although rare, this medication can cause severe and potentially life-threatening side effects. If you experience any of the following symptoms, contact your doctor or seek medical attention right away:

Special Patient Groups
Pregnancy
Category C. Prolonged use during pregnancy can result in neonatal opioid withdrawal syndrome (NOWS), which may be life-threatening. Use only if the potential benefit justifies the potential risk to the fetus.
Trimester-Specific Risks:
Lactation
L3 (Moderate risk). Both oxycodone and acetaminophen are excreted into breast milk. Monitor infants for signs of sedation, respiratory depression, poor feeding, and withdrawal symptoms. Acetaminophen is generally considered safe for breastfeeding infants at usual doses. Oxycodone should be used with caution, and the lowest effective dose for the shortest duration should be considered.
Pediatric Use
Safety and efficacy have not been established in pediatric patients under 18 years of age. Not recommended for use in this population due to the risks of opioid analgesics and the potential for accidental overdose.
Geriatric Use
Use with caution. Elderly patients may be more sensitive to the analgesic and adverse effects of opioids, including respiratory depression, sedation, and constipation. Start with lower doses and titrate slowly. Monitor renal and hepatic function closely.
Clinical Information
Clinical Pearls
- Due to the acetaminophen component, ensure patients are not taking other acetaminophen-containing products to avoid exceeding the maximum daily dose (4000 mg, or 3000 mg in some clinical settings/products).
- Educate patients on the serious risks of addiction, abuse, and misuse, and the importance of safe storage and disposal.
- Monitor for signs of respiratory depression, especially during initiation or dose escalation, and advise patients on when to seek emergency care.
- Counsel patients on the risks of concomitant use with alcohol, benzodiazepines, or other CNS depressants.
- For chronic pain management, consider non-opioid alternatives or lower-dose opioid regimens. If long-term opioid therapy is necessary, implement a comprehensive pain management plan including risk mitigation strategies.
- Taper dose gradually when discontinuing after prolonged use to prevent opioid withdrawal symptoms.
Alternative Therapies
- NSAIDs (e.g., ibuprofen, naproxen)
- Other non-opioid analgesics (e.g., celecoxib)
- Other opioid analgesics (e.g., morphine, hydromorphone, fentanyl) for severe pain, used alone
- Adjuvant analgesics (e.g., gabapentin, pregabalin, tricyclic antidepressants) for neuropathic pain
- Non-pharmacological therapies (e.g., physical therapy, acupuncture, massage, cognitive behavioral therapy)
