oxycodone (Rx)

Moderate-to-Severe Pain

Immediate-release

• Opioid-tolerant:: 10-30 mg PO q4-6hr
• Opioid-naïve (initial dose): 5-15 mg PO q4-6hr

Chronic Severe Pain

Controlled-release products (eg, OxyContin, Xtampza ER) are indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate

Also see Administration

Initial dosing

• OxyContin

  • Opioid-naïve patients: 10 mg PO q12hr initially; titrate gradually every 1-2 days, increasing by 25-50% increments, with q12hr dosing interval maintained
  • A single dose >40 mg ER or total dose >80 mg ER are for use only in opioid-tolerant patients

• Xtampza ER

  • Opioid-naïve patients: 9 mg PO q12hr with food

Dosage Modifications

Coadministration with other CNS depressants: Initiate long-acting oxycodone with one-third to one-half the recommended starting dose; monitor for signs of respiratory depression, sedation, and hypotension

Conversion from other opioids to OxyContin

• Provide immediate-release opioids for breakthrough pain
• Monitor patient closely for adverse effects or breakthrough pain during conversion and for several days following
• Also see Medscape reference topic - Opioid Equivalents

• Conversion from other oral oxycodone formulations

  • Conversion from other oral oxycodone formulations: Administer one-half of the patient's total daily PO oxycodone dose as q12hr
  • Conversion from fentanyl transdermal: Wait 18 hr after patch removed, then initiate conservative dose of ~10 mg q12hr oxycodone controlled-release for each 25 mcg/hr fentanyl transdermal patch

• Conversion from fentanyl transdermal

  • Wait 18 hr after patch removed, then initiate conservative dose of ~10 mg q12hr oxycodone controlled-release for each 25 mcg/hr fentanyl transdermal patch

Conversion from other opioids to Xtampza ER

• Conversion from other oral oxycodone formulations

  • Administer one-half of the patient's total daily PO oxycodone dose as q12hr with food
  • Because Xtampza ER is not bioequivalent to other oxycodone extended-release products
  • Monitor patients for possible dosage adjustment

• Conversion from other opioids

  • Discontinue all other around-the clock opioid drugs
  • There are no established conversion ratios for conversion from other opioids to Xtampza ER defined by clinical trials
  • Initiate dosing using 9 mg PO q12hr with food and provide immediate-release rescue medication while stabilizing patient on Xtampza ER

• Conversion from methadone

  • Close monitoring is of particular importance when converting from methadone to other opioid agonists; the ratio between methadone and other opioid agonists may vary widely as a function of previous dose exposure and methadone has a long half-life and can accumulate in the plasma

• Conversion from fentanyl transdermal

  • 18 hr following the removal of the transdermal fentanyl patch, initiate Xtampza ER; there has been no systematic assessment of such conversion, a conservative oxycodone dose, ~9 mg (equivalent to 10 mg oxycodone HCl) q12hr should be initially substituted for each 25 mcg/hr fentanyl transdermal patch

Renal impairment

• CrCl <60 mL/min: Serum concentration may increase by 50%; adjust dosage to response

Hepatic impairment

• Reduce dosage in liver disease; decrease dosage of extended-release form to 1/3 or 1/2 of usual starting dosage; titrate to response
• Alternative analgesics are recommended for patients who require a dose of Xtampza ER <9 mg

Dosing Considerations

Access to naloxone for opioid overdose

• Assess need for naloxone upon initiating and renewing treatment

• Consider prescribing naloxone

  • Based on patient’s risk factors for overdose (eg, concomitant use of CNS depressants, a history of opioid use disorder, prior opioid overdose); presence of risk factors should not prevent proper pain management
  • Household members (including children) or other close contacts at risk for accidental ingestion or overdose

• Consult patients and caregivers on the following:

  • Availability of naloxone for emergency treatment of opioid overdose
  • Ways differ on how to obtain naloxone as permitted by individual state dispensing and prescribing requirements or guidelines (eg, by prescription, directly from a pharmacist, as part of a community-based program)

Discontinuation

• Use a gradual downward titration of the dosage to avoid signs and symptoms of withdrawal in the physically-dependent patient
• Do not abruptly discontinue Xtampza ER

Opioid-tolerant definition

• Use of higher starting doses in patients who are not opioid tolerant may cause fatal respiratory depression
• Patients who are opioid tolerant are those receiving, for 1 week or longer, at least 60 mg/day PO morphine, 25 mcg/hr transdermal fentanyl, 30 mg/day PO oxycodone, 8 mg/day PO hydromorphone, 25 mg/day PO oxymorphone, or an equianalgesic dose of another opioid

Limitations of use

• Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risks of overdose and death with extended-release opioid formulations, reserve for patients whom alternative treatment options (eg, nonopioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain
• Long-acting opioids are not indicated as a PRN analgesic

Moderate-to-Severe Pain

Immediate-release: 0.05-0.15 mg/kg PO q4-6hr PRN  

Chronic Severe Pain

Controlled-release (ie, OxyContin) is indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate in opioid-tolerant pediatric patients aged ≥11 yr who are already receiving and tolerate a minimum daily opioid dose of at least 20 mg oxycodone orally or its equivalent

Note: Xtampza ER is not approved for children or adolescents younger than 18 yr

Initial dose

• Dosing information is only for children ≥11 yr who are already receiving and tolerating opioids for at least 5 consecutive days, and for the 2 days immediately preceding dosing with OxyContin, patients must be taking a minimum of 20 mg/day of oxycodone or its equivalent
• Not appropriate for use in pediatric patients requiring <20 mg/day
• Discontinue all other around-the-clock opioid drugs when OxyContin is initiated
• Also see Administration

Converting to OxyContin in children ≥11 yr

• Although tables of oral and parenteral equivalents are readily available, there is substantial interpatient variability in the relative potency of different opioid drugs and formulations
• As such, it is preferable to underestimate a patient’s 24-hr oral oxycodone requirements and provide rescue medication (eg, immediate-release opioid) than to overestimate the 24-hr oral oxycodone requirements and manage adverse effects

• Conversion factors of prior opioid

  • Oxycodone PO: 1
  • Hydrocodone PO: 0.9
  • Hydromorphone PO: 4
  • Hydromorphone parenteral: 20
  • Morphine PO: 0.5
  • Morphine parenteral: 3
  • Tramadol PO 0.17
  • Tramadol parenteral: 0.2
  • NOTE: For patients receiving high-dose parenteral opioids, a more conservative conversion is warranted; for example, for high-dose parenteral morphine, use 1.5 instead of 3 as a multiplication factor

Conversion steps to OxyContin

• Use the conversions listed above

• Step 1 – calculate daily opioid dose(s)

  • Pediatric patients taking a single opioid: Add the current total daily dosage of the opioid and then multiply the total daily dosage by the approximate conversion factor to calculate the estimated OxyContin daily dose
  • Pediatric patients on a regimen of >1 opioid: Calculate the approximate oxycodone daily dose for each opioid and add the daily totals to obtain the approximate OxyContin dose/day
  • Pediatric patients on a regimen of fixed-ratio opioid/nonopioid analgesic products: Use only the opioid component of these products in the conversion

• Step 2 – round dose down

  • If rounding is necessary, always round the dosage down to the nearest tablet strength available and initiate OxyContin therapy with that dose
  • If the calculated oxycodone daily dosage is <20 mg, there is no safe strength for conversion and do not initiate
  • Example: Conversion from a single opioid (eg, hydrocodone) to OxyContin; using the conversion factor of 0.9 for oral hydrocodone, a total daily hydrocodone dosage of 50 mg is converted to 45 mg/day of oxycodone or 22.5 mg q12hr of OxyContin
  • After rounding down to the nearest strength available, the recommended OxyContin starting dosage is 20 mg q12hr

• Step 3 – closely observe and titrate

  • Following conversion, observation and titration are warranted until pain management is stable
  • Monitor for signs and symptoms of opioid withdrawal or for signs of oversedation/toxicity

OxyContin titration and maintenance

• Individually titrate to a dosage that provides adequate analgesia and minimizes adverse reactions
• Continually re-evaluate pain control, signs and symptoms of opioid withdrawal, and adverse reactions, as well as monitoring for the development of addiction, abuse and misuse
• If breakthrough pain occurs, may require a dosage increase of OxyContin or a short-acting rescue analgesic
• If the level of pain increases after dose stabilization, attempt to identify the source of increased pain before increasing the OxyContin
• Because steady-state plasma concentrations are approximated in 1 day, may adjust OxyContin dose every 1-2 days
• As a guideline for children ≥11 yr, the total daily oxycodone dosage usually can be increased by 25% of the current total daily dosage

Dosage Modifications

Coadministration with other CNS depressants: Initiate OxyContin with one-third to one-half the recommended starting dose; monitor for signs of respiratory depression, sedation, and hypotension

Dosing Considerations

Long-acting or controlled-release oxycodone is not indicated for PRN analgesic dosing

Reduce starting dose to one-third to one-half of usual starting dosage; titrate cautiously

Contraindicated (1)

• alvimopan

  alvimopan, oxycodone. receptor binding competition. Contraindicated. Alvimopan is contraindicated in opioid tolerant patients (ie, those who have taken therapeutic doses of opioids for >7 consecutive days immediately prior to taking alvimopan). Patients recently exposed to opioids are expected to be more sensitive to the effects of alvimopan and therefore may experience abdominal pain, nausea and vomiting, and diarrhea. No significant interaction is expected with concurrent use of opioid analgesics and alvimopan in patients who received opioid analgesics for 7 or fewer consecutive days prior to alvimopan.
