Probable Interaction Between Warfarin and the Combination of Remdesivir With Dexamethasone for Coronavirus Disease 2019 (COVID-19) Treatment : A 2 Case Report

PURPOSE: To describe a potential drug interaction between warfarin and the combination of remdesivir with dexamethasone.

SUMMARY: Two male patients, a 71-year-old and 62-year-old presented to the emergency department for symptoms of coronavirus disease 2019 (COVID-19). Both patients were on long-term warfarin therapy with their most recent international normalized ratio (INR) prior to admission within their patient specific goal as managed by their outpatient Pharmacist. In both instances, the patients denied any changes in diet, lifestyle, or missed doses of medications upon admission interview. During admission, both patients experienced a marked elevation in INR within 24 to 48 hours of the initiation of remdesivir with dexamethasone for COVID-19 pneumonia directed therapy. The patients were both eventually stable and were instructed to continue warfarin monitoring and management under the direction of their outpatient Pharmacist upon discharge.

CONCLUSION: The underrecognized but probable interaction between warfarin in conjunction with remdesivir and dexamethasone warrants further analysis.
