Overdose Information
Overdose Symptoms:
- Slowed or stopped breathing (respiratory depression)
- Extreme drowsiness progressing to stupor or coma
- Pinpoint pupils
- Cold, clammy skin
- Flaccid skeletal muscles
- Low blood pressure
- Slowed heart rate
- Circulatory collapse
- Liver failure (from acetaminophen, may be delayed 24-48 hours, symptoms include nausea, vomiting, abdominal pain, loss of appetite, dark urine, jaundice)
What to Do:
Seek immediate emergency medical attention. Call 911 or your local emergency number. For suspected acetaminophen overdose, call a poison control center immediately (1-800-222-1222). Naloxone (Narcan) may be administered for opioid overdose symptoms. N-acetylcysteine (NAC) is the antidote for acetaminophen overdose.
Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs) (within 14 days of use) - risk of serotonin syndrome or severe respiratory depression
- Strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, clarithromycin) - risk of increased oxycodone plasma concentrations and respiratory depression
- Strong CYP2D6 inhibitors (e.g., quinidine, fluoxetine, paroxetine) - risk of decreased oxymorphone formation and potentially reduced efficacy, or increased oxycodone levels if CYP3A4 is also inhibited
Major Interactions
- Other CNS depressants (e.g., benzodiazepines, other opioids, alcohol, sedatives, hypnotics, general anesthetics, phenothiazines, tranquilizers, muscle relaxants) - risk of profound sedation, respiratory depression, coma, and death
- Serotonergic drugs (e.g., SSRIs, SNRIs, TCAs, triptans) - risk of serotonin syndrome
- Anticholinergic drugs (e.g., atropine, scopolamine) - risk of paralytic ileus and/or urinary retention
- Mixed agonist/antagonist opioids (e.g., pentazocine, nalbuphine, butorphanol) - may reduce analgesic effect and/or precipitate withdrawal symptoms
- Opioid antagonists (e.g., naltrexone, naloxone) - may precipitate withdrawal symptoms
- Drugs that affect gastric emptying (e.g., metoclopramide, propantheline) - may alter absorption of oxycodone
Moderate Interactions
- Moderate CYP3A4 inhibitors/inducers
- Moderate CYP2D6 inhibitors/inducers
- Hepatotoxic drugs (e.g., isoniazid, methotrexate) - increased risk of acetaminophen-induced hepatotoxicity
- Warfarin - increased risk of bleeding with chronic high-dose acetaminophen
Minor Interactions
- Not typically listed as minor for this combination due to significant risks associated with major/contraindicated interactions.
Monitoring
Baseline Monitoring
Rationale: To establish baseline pain level and guide initial dosing.
Timing: Prior to initiation of therapy.
Rationale: To assess baseline respiratory function and identify risk for respiratory depression.
Timing: Prior to initiation of therapy.
Rationale: To assess baseline mental status and identify risk for excessive sedation.
Timing: Prior to initiation of therapy.
Rationale: To assess baseline hepatic function due to acetaminophen component, especially in patients with pre-existing liver disease or risk factors.
Timing: Prior to initiation of therapy, if clinically indicated.
Rationale: To assess baseline renal function, as metabolites of oxycodone are renally excreted.
Timing: Prior to initiation of therapy, if clinically indicated.
Rationale: To identify patients at higher risk for addiction, abuse, or misuse.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Regularly, as per clinical need (e.g., daily, at each visit)
Target: Acceptable pain control with improved function
Action Threshold: Inadequate pain relief or worsening pain may require dose adjustment or alternative therapy.
Frequency: Frequently during initiation/titration, then periodically
Target: Normal for patient (e.g., >10-12 breaths/min)
Action Threshold: Respiratory rate <10 breaths/min, shallow breathing, or signs of hypoventilation require immediate intervention.
Frequency: Frequently during initiation/titration, then periodically
Target: Alert and oriented, or easily aroused
Action Threshold: Excessive sedation (e.g., somnolence, difficulty arousing) requires dose reduction or discontinuation.
Frequency: Daily
Target: Regular bowel movements
Action Threshold: Constipation requires prophylactic measures (e.g., stool softeners, laxatives).
Frequency: Periodically, especially with long-term or high-dose use
Target: Absence of signs/symptoms
Action Threshold: Any signs of liver injury require immediate discontinuation and investigation.
Symptom Monitoring
- Respiratory depression (slow, shallow breathing)
- Excessive sedation or somnolence
- Confusion or disorientation
- Pinpoint pupils
- Nausea and vomiting
- Constipation
- Pruritus (itching)
- Dizziness or lightheadedness
- Signs of liver injury (yellowing of skin/eyes, dark urine, severe abdominal pain, fatigue)
Special Patient Groups
Pregnancy
Category C. Use during pregnancy should only be considered if the potential benefit justifies the potential risk to the fetus. Prolonged use during pregnancy can result in neonatal opioid withdrawal syndrome (NOWS), which may be life-threatening if not recognized and treated.
Trimester-Specific Risks:
Lactation
Oxycodone is excreted into breast milk and can cause serious adverse reactions in breastfed infants, including sedation and respiratory depression. Acetaminophen is generally considered safe for use during breastfeeding at usual doses. Due to the oxycodone component, it is generally not recommended for use in breastfeeding mothers. If use is unavoidable, monitor the infant closely for signs of sedation, difficulty feeding, and breathing problems.
Pediatric Use
Safety and efficacy have not been established in pediatric patients. Use is generally not recommended due to the risks of respiratory depression and potential for overdose, especially in very young children. If used in adolescents, extreme caution and careful monitoring are required.
Geriatric Use
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 closely for CNS and respiratory depression.
Clinical Information
Clinical Pearls
- Always counsel patients on the maximum daily dose of acetaminophen (4000 mg, or 3000 mg for chronic use/hepatic risk) to prevent hepatotoxicity.
- Emphasize the risk of addiction, abuse, and misuse, and the importance of proper storage and disposal.
- Educate patients on the signs of respiratory depression and the importance of seeking immediate medical attention.
- Prophylactic treatment for opioid-induced constipation should be initiated at the start of therapy.
- Caution patients about concomitant use of alcohol or other CNS depressants.
- Consider prescribing naloxone for patients at increased risk of opioid overdose (e.g., history of overdose, concomitant benzodiazepine use, higher doses).
Alternative Therapies
- Non-opioid analgesics (e.g., NSAIDs like ibuprofen, naproxen; celecoxib)
- Other opioid analgesics (e.g., morphine, hydromorphone, fentanyl - for severe pain)
- Tramadol
- Non-pharmacological pain management (e.g., physical therapy, acupuncture, massage, heat/cold therapy, cognitive behavioral therapy)
