Warfarin / INR

When the doctors have prescribed WARFARIN tablets for you it is important that the practice nurses do regular blood tests to make sure you are always taking the right dose.

The blood test is done at the surgery using a special machine and a drop of blood from a finger prick. The result (called the INR) will be in a ‘target range’ that all patients who are taking warfarin will have been told and have written down for reference. This is usually written in your warfarin yellow treatment book. If you do not have one of these books then please ask the nurse who will provide you with one and show you how it is used.

The dose will be adjusted according to the result, i.e. whether it is inside or outside the target range.

The nurses will always write down the result for you and give you an appointment for the next test before you leave the surgery.

In some cases we have to take a blood sample from the vein in the arm, and send it to the hospital laboratory in Carlisle. In this case the result will be phoned to you the following day or that evening.

Please try and always remember to bring your warfarin yellow reference book with you when you come to the surgery.

A variety of information leaflets are available about warfarin. Please ask the practice nurse.
