Does anyone know what this means, please, on the Patient Leaflet in my pack of Nature Throid? I'm taking vitamin k with my vitamin D so I found this warning baffling:
'Drug Interactions: oral anticoagulants: Thyroid hormones appear to increase catabolism of vitman k- dependent clotting factors. If oral anticoagulants are also being given, compensatory increases in clotting factor synthesis are impaired. Patients stabilised on oral coagulants should be watched very closely when thyroid replacement treatment is started. If a patient is truly hypothyroid, it is likely that a reduction in anticoagulant dose will be required. No special precautions appear to be necessary when oral anticoagulant therapy is begun in a patient already stabilised on thyroid replacement therapy.'
I'm not taking anticoagulants. I am taking vitamin k to make sure vitamin D gets into my bones not soft tissues.
I cannot decipher the warning, although I realise that 'catabolism' means breaks down..
