Oral Anticoagulants: There is a risk of serious hemorrhage and significant elevations in INR and prothrombin time when clarithromycin is co-administered with warfarin.
Monitor INR and prothrombin times frequently while patients are receiving clarithromycin tablets and oral anticoagulants concurrently [see Drug Interactions ( 7 )] .
Oral Anticoagulants: Warfarin Use With Caution Oral anticoagulants: Spontaneous reports in the postmarketing period suggest that concomitant administration of clarithromycin and oral anticoagulants may potentiate the effects of the oral anticoagulants.
Prothrombin times should be carefully monitored while patients are receiving clarithromycin and oral anticoagulants simultaneously [see Warnings and Precautions ( 5.4 )] .
From the Edoxaban (SAVAYSA) label · effective 2025-07-10
P-gp Inhibitors Treatment of NVAF Based on clinical experience from the ENGAGE AF-TIMI 48 study, dose reduction in patients concomitantly receiving P-gp inhibitors resulted in edoxaban blood levels that were lower than in patients who were given the full dose.
Consequently, no dose reduction is recommended for concomitant P-gp inhibitor use [see Dosage and Administration (2.1) , Clinical Pharmacology (12.3) , and Clinical Studies (14.1) ] .
