Phytomenadione 1mg/0.5mL Injection

Product Introduction

Phytomenadione 1mg/0.5mL is vitamin K1 injection used to prevent or treat bleeding related to vitamin K deficiency or impaired vitamin K activity. The 1mg presentation is used in some neonatal protocols, with the route and dose selected for the individual clinical situation.

How to use

A clinician gives phytomenadione by intramuscular, slow intravenous or subcutaneous injection. The route and amount depend on whether treatment is newborn prophylaxis or correction of vitamin K-related bleeding. Protect the preparation from light; it is not for self-injection.

How it works

Vitamin K1 enables the liver to produce functional clotting factors II, VII, IX and X. Restoring these factors improves clotting when vitamin K deficiency or antagonism is responsible.

Side effects

Pain, swelling or tenderness at the injection site can occur. Severe hypersensitivity, including anaphylaxis, has occurred with parenteral vitamin K, particularly intravenous or intramuscular emulsion administration.

Important information

Tell the treating team about anticoagulants, liver disease and previous injection reactions. Injectable vitamin K formulations differ in their permitted routes and excipients. Severe active bleeding requires emergency treatment because vitamin K alone does not act immediately.
