Warfarin may also be prescribed for people:

• with a condition that increasing the risk of a blood clot developing, such as atrial fibrillation
• with a prosthetic heart valve
• patients that have suffered a  heart attack

The length of time you are supposed to take warfarin will depend on the condition in which you were prescribed it for. If you are not sure, ask your pharmacist or GP. You will also be given a yellow booklet on anticoagulants, which explains your treatment.

Our pharmacist will take your blood sample and then by using the effective INRstar system to provide an immediate result. The pharmacist will then amend your yellow booklet with the date and correct warfarin dose for each patient dependent on the test results of the day.
