- Oxycodone And Aspirin + Acetazolamide— Concurrent use with aspirin can lead to high serum acetazolamide concentrations and toxicity due to competition at renal…
- Oxycodone And Aspirin + Carbamazepine— CYP450 inducer may increase clearance of oxycodone, leading to decreased plasma concentrations and potential lack of eff…
- Oxycodone And Aspirin + Heparin— Aspirin increases anticoagulant activity of heparin, significantly increasing bleeding risk.
- Oxycodone And Aspirin + Methotrexate— Aspirin may enhance serious side effects and toxicity of methotrexate through protein binding displacement.
- Oxycodone And Aspirin + Phenytoin— CYP450 inducer may increase clearance of oxycodone; salicylate can also displace protein-bound phenytoin, decreasing its…
- Oxycodone And Aspirin + Rifampin— CYP450 inducer decreases oxycodone AUC by 86% and Cmax by 63%, potentially causing lack of efficacy or abstinence syndro…
- Oxycodone And Aspirin + Voriconazole— CYP3A4 inhibitor increases oxycodone AUC 3.6-fold and Cmax 1.7-fold, resulting in increased or prolonged opioid effects.
- Oxycodone And Aspirin + Warfarin— Aspirin displaces warfarin from protein binding, prolonging prothrombin time and bleeding time, increasing bleeding risk…
Moderate (7)
- Oxycodone And Aspirin + Diuretics— Aspirin may reduce diuretic effectiveness by inhibiting renal prostaglandins and causing salt and fluid retention.
