There are certain medical conditions which make developing blood clots more likely such as Atrial fibrillation, Cancer, thrombophilia and mechanical heart valves. Patients are often given oral anticoagulants to reduce the risk of future clots.
They are given to people at a high risk of developing clots to reduce their chances of developing serious conditions such as strokes and heart attacks. They are also given to patients who have already developed deep vein thrombosis (DVT) or Pulmonary embolism. Patients will be referred into the service by their GP or by a hospital A&E or inpatient ward. Our Anticoagulant Clinic monitors the treatment of patients taking oral anticoagulants.

About Vitamin K
Vitamin K blocks the action of coumadin. Some foods such as green vegetables have a lot of vitamin K in them, so you need to each such foods in a consistent manner or your coumadin level may need to be adjusted.
If you have any questions or concerns, talk to your doctor or a nurse at the Anticoagulation Clinic.
The INR is a blood test that determines the dose of jantoven/coumadin you need.
We will do a finger stick to get the amount of blood needed for that test. On occasion, we will need to perform a venipuncture to verify the INR result.
We will contact you with your lab results and any changes that need to be made in your jantoven/coumadin dosage.
If you do not hear from us the day you have your blood drawn, take your usual dose of warfarin/coumadin and we will call you the next day.

Coumadin Therapy FAQs
What is Coumadin
Coumadin is a medicine that reduces your blood’s ability to form dangerous clots.Good clots form when you get cuts and bruises to prevent you from bleeding too much. Bad clots form inside blood vessels and can break off, blocking blood flow to vital parts of your body.
Your doctor will prescribe a dose of coumadin to prevent dangerous clots from forming, while allowing good clots to protect you from bleeding.
How will my doctor know if coumadin is working for me?
To be sure the balance between good and bad clotting is right, your doctor will order a regular blood test that shows how fast your blood clots. Your coumadin dose may be adjusted depending on your test results.
Your doctor will ask to enroll you in AHCPC Anticoagulation Clinic, also known informally as the Coumadin Clinic, to have these regular blood tests done.
The clinic will contact you a day or two after you leave the hospital to arrange for your first blood test at the clinic.
The clinic has a physician and several nurses on staff. You will first see the physician for a brief visit and then the nurses will do the blood tests and call you with any changes in your coumadin dose.
If you do not hear from the nurse the day of your blood test, take your usual dose for that day and the nurse will call you the next day.
What may cause problems for me while I'm on coumadin?
Bleeding problems may happen when the amount of coumadin in your blood increases. This can happen if:
- The way your body uses coumadin changes
- You drink alcohol
- You take medicines that interfere with how your body uses coumadin
- You eat certain foods that interfere with how your body uses coumadin
