Coumadin Clinic

Fort Worth Heart is proud to work closely with Roche Laboratories in establishing our "Point of Care" Coumadin clinic. Our clinics see over 1200 patients monthly to have their Coumadin levels checked, have on going education and emotional support they need. Coumadin is commonly called " the blood thinner." There are a few restrictions and rules when taking Coumadin but our staff of Coumadin nurses and medical assistants are well trained and always available. Point of Care clinics provide immediate results- no waiting for lab results to adjust Coumadin. We also provide on-going education and are ready to assist when patients have special needs due to other medical procedures that impact their Coumadin therapy. It is goal of each Coumadin staff member to take the apprehension out of taking Coumadin and assist the patient in living with Coumadin.

Suggestions for Optimal Coumadin/Warfarin Therapy

  • NEVER SELF-DOSE COUMADIN! This can be very dangerous and even fatal.
  • If you miss a dose of Coumadin, do not double up your dose the next day. You may either notify the Coumadin nurse that day or make a note and inform the Coumadin nurse of the missed dose on your next INR check/visit.
  • Routinely take your Coumadin medication after 5:00pm – preferably 30 minutes prior to your evening meal.
  • Notify the Coumadin nurse with any medication changes, especially if you take antibiotics, steroids or pain medications. Also, please notify the nurse if you stop taking any medications you were previously taking as this could affect your Coumadin dosing.
  • Never start over-the-counter (OTC) medications without checking with the Coumadin nurse in advance. If you are doing this on the weekend, please call your pharmacist and ask them if the medication(s) could interfere with Coumadin and know their possible side effects.
  • The only over-the-counter (OTC) pain medication that can be safely taken with Coumadin is Tylenol 325mg (acetaminophen). The only exception to this is where other pain medications were known in advance and previously calculated into your Coumadin dosing by the Coumadin nurse. Always consult your physician/nurse about this.
  • Please inform your Coumadin nurse if another physician or nurse (PCP, etc.) tells you to stop Coumadin for any reason.
  • Please inform your Cardiologist if you have any medical procedures scheduled that require you to stop/hold your Coumadin. In most cases, you will need Cardiac Clearance prior to that procedure. You may also need to be given Lovenox injections to keep your blood levels safe while you are off Coumadin.
  • Lovenox injections are used to keep your blood “slippery” while you are off your normal Coumadin therapy.
  • Avoid consuming green tea, cranberries, cranberry juice or anything containing cranberries as they may cause an unsafe INR level and cause your blood to be too thick or too thin.
  • Limit your Vitamin K intake to no more than two (2) cups of greens every 7 days, unless you have been otherwise directed by your Coumadin nurse.
  • Additional Vitamin K information can be found on the internet by using the address: 

A list of some of the “Green” foods that contain Vitamin K are as follows:

Turnip Greens, Mustard Greens, Collard Greens, Kale, Asparagus, English Peas, Avocados, Spinach, Brussel Sprouts, Broccoli, Kiwi Fruit, most Lettuces and other green leafy vegetables. In addition, Cabbage, Cauliflower and Blueberries are also included in this group even though they are not actually green.
