INR (international normalized ratio) clinic


The INR (international normalized ratio) clinic will help you manage your anticoagulation therapy. The goal of the clinic is to ensure your medicine is working as well as it should and to educate you so you don’t have problems with your therapy.

Anticoagulants or blood thinner are medicine that is used to prevent unwanted blood clots from forming (Warfarin, Coumadin® or Jantoven®). Once you start taking this medicine, you will need to have blood tests often to monitor your clotting time. This is done with a blood test.

You may need to have it checked more often when you first start taking anticoagulants, if your INR is not in the goal range, or if you have changes in your health, other medicines or diet. You will need to have your INR checked at least every month.

At the INR clinic you will work closely with a doctor and nurse. The nurse will see you on a regular basis and help you learn all you need to know to take your anticoagulation medicine safely.
