The answer

The measurement you seem to be referring to is one called INR – this is a ratio of how long your blood takes to clot. Blood thinning agents are often used to reduce your risk of clots if you have a condition which increases that risk. Conditions which increase the risk include atrial fibrillation or AF (the commonest abnormal heart rhythm in the UK), is a history of DVT (clot on the leg) or pulmonary embolus (clot on the lung) or artificial heart valves. Your doctor will aim to keep your INR within a certain range, which will vary depending on which of these conditions you’re taking warfarin for. It is important to take the right dose to get your INR into this ‘therapeutic range’, because you won’t be protected against clots if your INR is too low and you’re at risk of bleeding if it’s too high. While warfarin is extremely effective at reducing the risk of clots, it can be very difficult to manage. The dose of medicine different people need to achieve the same INR varies enormously, and a huge number of foods, drinks and medications can affect your INR. For instance, if you eat broccoli, brussel sprouts, spinach or some salads, it can affect you INR; so too can alcohol, cranberry juice and herbal remedies, to name but a few. Speak to your nurse to get a full list of the medicines and foods you need to avoid.
