Contraindications

ConditionSeverityNote
Respiratory
pre-existing respiratory depressionabsolute

Patients with significant respiratory depression, acute or severe bronchial asthma in unmonitored settings, or hypercarbia must not receive oxycodone. The additive respiratory suppression can be rapidly fatal.

acute bronchospasmabsolute

Active bronchospasm or status asthmaticus in unmonitored settings is an absolute contraindication due to compounded ventilatory compromise.

Psychiatric
concurrent MAOI userelative

Concurrent or recent MAOI use (within 14 days) significantly increases risk of serotonin syndrome and potentiated CNS depression. Case reports of serotonin syndrome with oxycodone + serotonergic agents exist despite oxycodone lacking direct SERT inhibition.

substance use disorder historyrelative

History of substance use disorder significantly increases risk of oxycodone misuse and addiction. Misuse rates of 21-29% and addiction rates of 8-12% documented in chronic pain populations. Careful risk-benefit assessment required.

Hepatic
hepatic impairmentrelative

Hepatic impairment requires dose reduction and careful monitoring. Reduced CYP3A4/CYP2D6 metabolism prolongs oxycodone elimination and increases risk of respiratory depression.

Renal
renal impairmentrelative

Renal impairment requires dose adjustment and monitoring. Accumulation of oxycodone and metabolites increases risk of prolonged CNS and respiratory depression.

Metabolic
concurrent CYP3A4 inhibitor userelative

Co-administration with strong CYP3A4 inhibitors substantially increases oxycodone exposure and risk of respiratory depression. Dose reduction and enhanced monitoring required. PBPK modeling confirms dramatic exposure increases.

Pregnancy & Breastfeeding
pregnancyrelative

Oxycodone use during pregnancy is associated with NOWS in newborns requiring pharmacological treatment. Perinatal exposure causes long-term neurodevelopmental changes in animal models. Use only when benefits clearly outweigh risks.

Age
elderlyrelative

Elderly patients require reduced initial doses and careful titration. Increased sensitivity to respiratory depression, sedation, and falls risk. Immunosuppressive effects of chronic use are particularly concerning in this population.

Other
paralytic ileus or gastrointestinal obstructionabsolute

Known or suspected paralytic ileus or mechanical gastrointestinal obstruction is an absolute contraindication. Opioid-induced reduction in gut motility exacerbates obstruction.

known hypersensitivity to oxycodoneabsolute

Known hypersensitivity to oxycodone or any component of the formulation is an absolute contraindication.
