Anti-coagulant (Warfarin) clinic



Warfarin is a drug given to anticoagulate the blood, that is, to lengthen the time it takes for blood to clot. It is prescribed for various conditions in which there is the risk of abnormal blood clots developing. It is commonly used for the following:

• Atrial fibrillation (an irregularity of the heart rhythm)
• Deep vein thrombosis of the leg (DVT)
• Thrombosis in the lung (pulmonary embolism)
• Prosthetic (artificial) heart valve

If you take warfarin for any reason, you will need to have your blood monitored to check that you are not over- or under-dosed i.e. to make sure that your blood is not "too thick" or "too thin". If the clotting time is too short ("thick") you would be more at risk of a clot developing, if the clotting time is too long ("thin") you would be more at risk of bleeding.

We provide a state-of-the-art anticoagulation monitoring service. We use a near-patient testing machine, which gives accurate, reliable and instantaneous results simply by analyzing a drop of blood obtained using a finger-prick.

Marian Bradley, our pharmacist, has been trained to interpret the results and alter warfarin doses accordingly. She will also explain and discuss all aspects of taking warfarin with you. We have recently been part of a research study providing some patients with their own warfarin monitoring meter, allowing them, with training and support to monitor their own warfarin dose.
