Warfarin is a medication which reduces the risk of clots (“thins the blood”). It benefits patients with irregular heartbeats, previous clots in the legs or lungs, and those with surgical heart valves.
The effects of Warfarin need regular monitoring. When you are first started on Warfarin your doctor will arrange the tests and advise on what dosage you need to take.
When you are stable on Warfarin, it will be the John Radcliffe Hospital, special Warfarin Control Team who will monitor your care. They will send letters to you advising what dosage to take and when to have your test.
