Uses and dangers of vitamin K drugs

Abstract

There is abundant evidence that phytomenadione (vitamin K1) is the only vitamin K preparation that rapidly corrects prothrombin deficiency in patients taking oral anticoagulants. Intravenous administration of vitamin K1 has however caused some serious reactions, including one death, and should be avoided when oral or intramuscular administration will serve.
