Phenindione ‐ uncommon Vitamin K antagonist

AbstractWe would like to bring to your readership ’s attention to the drug phenindione. We came across this drug during a COVID‐19 pandemic phone triage at our dental hospital. A 48‐year‐old was referred for the management of a right sided facial swelling related to a carious unrestorable upper right molar. She had a complex medical histo ry, including rheumatic fever, total kidney failure with regular dialysis and was anticoagulated with phenindione following a tricuspid valve replacement as she was allergic to warfarin. When checked, her International Normalized Ratio (INR) was eight, likely due to untreated dental infection.
