What oxycodone is and how it works

Uses, formulations, monitoring, and supply rules can differ by patient, product, and country. Follow the exact local product information and professional advice.

Mechanism of action: how oxycodone works

Oxycodone is a semi-synthetic opioid agonist that primarily binds to mu-opioid receptors in the central nervous system. This binding inhibits ascending pain pathways, alters the perception and response to pain, and produces generalized CNS depression. It also has weak activity at kappa and delta opioid receptors.

How to take oxycodone

  • General Instructions: Take oxycodone exactly as prescribed by your healthcare provider. Do not increase your dose, take it more frequently, or use it for longer than directed.. Adult Dosing: Initial dosing varies by formulation and pain severity. For immediate-release: 5–15 mg orally every 4–6 hours as needed. Extended-release: typically 10 mg orally every 12 hours, adjusted as needed.. Pediatric Dosing: Not routinely recommended for children; dosing should be individualized and supervised by a pediatric pain specialist if used.. Administration: Swallow tablets/capsules whole with water. Do not crush, chew, or dissolve extended-release forms. Oral solution should be measured carefully with a dosing syringe.. When To Seek Review: Do not stop suddenly without consulting your doctor, as withdrawal symptoms may occur. Your doctor will guide you on how to taper the dose safely.. Storage: Store at room temperature, away from moisture and heat. Keep out of reach of children and dispose of unused medication safely.

Serious warnings

FDA BOXED WARNING — Addiction, Abuse, and Misuse — serious

Symptoms: FDA BOXED WARNING — Addiction, Abuse, and Misuse: Oxycodone exposes users to risks of addiction, abuse, and misuse, which can lead to overdose and death. Life-Threatening Respiratory Depression: serious, life-threatening, or fatal respiratory depression may occur, especially when starting oxycodone or following a dose increase; proper dosing and titration are essential. Accidental Ingestion: accidental ingestion of oxycodone, especially by children, can result in a fatal overdose. Neonatal Opioid Withdrawal Syndrome: prolonged use of oxycodone during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated; delivery should be planned where neonatology expertise is available. CYP3A4 Interaction: concomitant use with CYP3A4 inhibitors, or discontinuation of a co-administered CYP3A4 inducer, can result in a fatal oxycodone overdose. Interaction with Benzodiazepines or Other CNS Depressants: concomitant use of oxycodone with benzodiazepines or other central nervous system depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death — reserve concomitant prescribing for patients with no adequate alternative, use the lowest effective doses and durations, and monitor for respiratory depression and sedation.

Action: Follow the urgency stated and seek prompt or emergency care when indicated. (2)

Oxycodone can cause life-threatening respiratory depression, especially when starting or increasing the dose — serious

Symptoms: Oxycodone can cause life-threatening respiratory depression, especially when starting or increasing the dose. Risk of addiction, abuse, and misuse is high. Accidental ingestion, especially by children, can result in fatal overdose. Use in pregnancy may cause neonatal opioid withdrawal syndrome. Concomitant use with benzodiazepines or other CNS depressants increases risk of respiratory depression and death.

Action: Follow the urgency stated and seek prompt or emergency care when indicated. (2)

Contraindications recorded in the clinician database — serious

Symptoms: Contraindications recorded in the clinician database: Contraindications: Severe respiratory depression, acute or severe bronchial asthma, known or suspected gastrointestinal obstruction (including paralytic ileus), hypersensitivity to oxycodone.<br>Precautions: Use with caution in elderly, debilitated, hepatic or renal impairment, head injury, hypothyroidism, prostatic hypertrophy, or history of substance abuse.

Action: Follow the urgency stated and seek prompt or emergency care when indicated. (2)

Interactions

Medicine or testEffectAction
Recorded interactionsOxycodone interacts with other central nervous system depressants (such as benzodiazepines, alcohol, sedatives), increasing the risk of respiratory depression, profound sedation, coma, or death. CYP3A4 inhibitors (e.g., certain antibiotics, antifungals) can increase oxycodone levels, while CYP3A4 inducers (e.g., rifampin, phenytoin) can decrease its effectiveness. Always inform your healthcare provider about all medications and supplements you are taking. (1)

Pregnancy, breastfeeding, kidney/liver function, age

Pregnancy

Prolonged opioid use during pregnancy can cause neonatal opioid withdrawal syndrome (see boxed warning). Available human data with oxycodone in pregnant women are insufficient to establish a drug-associated risk of major birth defects or miscarriage. In animal studies, oxycodone given during organogenesis at several times the human dose did not show teratogenicity, but published studies found neurobehavioral effects in the offspring of rats treated with oxycodone at clinically relevant doses. Based on the animal data, pregnant women should be advised of a potential risk to the fetus. Discuss any pregnancy or plans for pregnancy with your prescriber. (2)

Breastfeeding

Oxycodone passes into breast milk. Data from a study of 76 breastfeeding women taking immediate-release oxycodone for postpartum pain found doses under 60 mg/day are unlikely to cause clinically relevant exposure in the breastfed infant (average milk-to-plasma ratio 3.2; relative infant dose about 1.3% of the weight-adjusted maternal dose); no adverse events were attributed to oxycodone in the 70 infants studied. Because of oxycodone's known adult effects, breastfed infants should still be monitored for excess sedation and breathing problems. Discuss breastfeeding with your prescriber. (2)

Children

Frequency: Not applicable.. Weight Based: Not recommended for pediatric use.. Max Daily Dose: Not applicable.. Max Single Dose: Not applicable.. Age Restrictions: Safety not established in children. (2)

Renal_impairment

Renal: because oxycodone is substantially excreted by the kidney, clearance may decrease in renal impairment. Start with a lower-than-usual dose and titrate carefully, with regular evaluation for respiratory depression, sedation, and low blood pressure. Hepatic: because oxycodone is extensively metabolized by the liver, clearance may decrease in hepatic impairment. Start with a lower-than-usual dose and titrate carefully, with the same monitoring for respiratory depression, sedation, and low blood pressure. (2)

Monitoring

(2)

Storage

Store oxycodone at 20-25°C (68-77°F); brief excursions between 15-30°C (59-86°F) are permitted. Protect from moisture. Because of the risk of accidental ingestion, misuse, and diversion, store oxycodone securely, out of sight and reach of children, and in a location not accessible by others, including visitors to the home; dispose of unused medication properly (for example through a drug take-back program).
