A vitamin K antagonist, or VKA, slows blood clotting by blocking vitamin K activity. The cited COUMADINE 2 mg leaflet explains this mechanism. It helps explain why diet matters when this treatment is monitored.
French Health Insurance advises consistent eating habits regarding vitamin K-rich foods. Additional vitamin K can reduce a VKA’s effectiveness. Discuss a change in your habits without adjusting the medicine yourself to compensate for it.
The COUMADINE leaflet lists cabbage, broccoli, spinach and asparagus among the relevant foods. It says these foods are not forbidden if eaten regularly and without excess. It does not provide a personal menu or a quantity suitable for everyone.
To prepare for the discussion, describe what you eat and what is changing in your meals. For example, note whether you plan a substantial change in how often you eat these vegetables. The doctor or pharmacist can consider this alongside your exact treatment.
Consistent eating does not replace prescribed monitoring. The COUMADINE leaflet explains that the doctor adjusts the dose using INR and that continued monitoring is necessary. Clarify your own instructions; a meal cannot tell you to choose a new dose yourself.
Show the name of your anticoagulant before applying this guidance. The cited sources concern VKAs. Do not transfer this dietary rule to every medicine described as an anticoagulant; ask the professional which precautions apply to yours.
