Anticoagulation Clinic

Make the most of your health and wellness.

What is an Anticoagulation Clinic?

A London Drugs Anticoagulation Clinic is an opportunity for patients taking warfarin to have an international normalized ratio (INR) test completed.

The INR test measures how long it takes for blood to clot. This information provides valuable insight about the effectiveness of medication. This is important because if an INR result is too high, there is an increased risk for bleeding. If it's too low, there is elevated risk for complications related to clotting (e.g., embolism, DVT, stroke).

How will you benefit from an Anticoagulation Clinic?

At select London Drugs locations, specially trained pharmacists can conduct your INR testing and work with you to help you get the most out of your anticoagulation therapy. A London Drugs Anticoagulation Clinic makes the process simple and convenient.

  • Your results will be available immediately. Using point-of-care testing, your London Drugs pharmacist can share the results of your INR test with you right away.
  • Your London Drugs pharmacist can adjust your medication. Based on your results, your London Drugs pharmacist can adjust your dosing during the clinic visit. Your pharmacist will take into consideration possible factors, like interactions with foods you eat or other medications you take, your age, and a host of other factors that may affect how your body handles warfarin.
  • Your care will be consistent. Your London Drugs pharmacist will share any dosing updates and insights with your physician, and will set times for repeat INR testing so they can monitor the effects of the dose adjustment.
  • Your London Drugs pharmacist can help you take your medication properly. Your London Drugs pharmacist can assist you with medication packaging to make it easier for you to take it safely and effectively.

What to know before your Anticoagulation Clinic visit

  • A clinic visit generally takes about 15 to 20 minutes.
  • The INR test requires your London Drugs pharmacist to take a blood sample. The only risks of this are slight discomfort from the needle prick and bruising or soreness at the site of the needle prick.
  • Be sure to bring along all of your prescription medications, over-the-counter drugs, and any herbal remedies you currently take. This will help give your pharmacist a comprehensive view of your medication routine.
  • You should also tell your pharmacist if you have recently eaten certain foods (such as green leafy vegetables) and about your regular alcohol intake, as these can affect the results of the test.
