What is Phytomenadione?
Phytomenadione, the active ingredient in Konakion Mm Paediatric Ampoules, is a vitamin K presented as an injectable solution for intramuscular, intravenous or oral use. It is employed to prevent and treat vitamin K deficiency bleeding, particularly in newborns, and to reverse anticoagulation caused by warfarin. GNH USA supplies Konakion Mm Paediatric Ampoules as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

What does Phytomenadione interact with?
Phytomenadione may interact with other medicines affecting coagulation.
Major Interactions (Avoid): - Warfarin: can diminish anticoagulant effect, leading to loss of therapeutic control. - Broad‑spectrum antibiotics (e.g., cephalosporins): may interfere with vitamin K synthesis, requiring careful monitoring.
Moderate Interactions (Monitor Closely): - Rifampin: may increase vitamin K metabolism, reducing efficacy. - Phenobarbital: induces hepatic enzymes that accelerate vitamin K clearance. - Oral contraceptives: potential additive effect on clotting factors, warranting observation.
