What the FDA labels say
From the Apixaban (ELIQUIS) label · effective 2026-04-24
For patients receiving ELIQUIS at a dose of 2.5 mg twice daily, avoid coadministration with combined P-gp and strong CYP3A4 inhibitors [see Dosage and Administration (2.6) and Clinical Pharmacology (12.3) ] .
• Combined P-gp and strong CYP3A4 inhibitors increase blood levels of apixaban.
Combined P-gp and Strong CYP3A4 Inhibitors For patients receiving ELIQUIS 5 mg or 10 mg twice daily, the dose of ELIQUIS should be decreased by 50% when coadministered with drugs that are combined P-gp and strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, ritonavir) [see Dosage and Administration (2.6) and Clinical Pharmacology (12.3) ] .
Concomitant use with drugs that are combined P-gp and strong CYP3A4 inhibitors increases exposure to apixaban [see Clinical Pharmacology (12.3) ] which increases the risk for bleeding.
Concomitant administration of combined P-gp and strong CYP3A4 inhibitors has not been studied in pediatric patients.

Coumarin-type anticoagulants Prothrombin time may be increased in patients receiving concomitant fluconazole and coumarin-type anticoagulants.
