Kenadion Injection

Let’s talk about Kenadion. If you’ve been in any kind of surgical, obstetric, or hepatology service for more than a week, you’ve seen it ordered. It’s one of those workhorse drugs that sits quietly in the pyxis until you have a patient bleeding from an INR you can’t even measure. I remember my first code as an intern, a cirrhotic with a GI bleed – the senior resident just barked “get the Kenadion” and it was like handing over the antidote.
