Anticoagulation Clinic Treatments and Services
The effects of anticoagulants must be monitored carefully with blood testing so that your warfarin doses can be adjusted accordingly. Our nurse specialists in the Anticoagulation Clinic work together with you, blood labs, and pharmacies to ensure that all blood tests and prescription doses are accurate and timely.
The success of anticoagulation therapy depends on your understanding and involvement. It's important that you attend all scheduled visits and take your medication as prescribed.
- Take your anticoagulant at the same time each day, preferably between 5:00 and 6:00 pm. If this is inconvenient, take it anytime in the evening. If you forget a dose, take it as soon as you realize you missed it, as long as it is the same day. Call the clinic for instructions if you realize you missed a dose on the following day.
- Report for your INR (International Normalised Ratio) / blood work appointment on the scheduled dates.
- Avoid, if you can, over-the-counter ibuprofen-based products, such as Advil or Motrin. If your doctor wants you to take aspirin, it is OK to continue to take it.
- Keep your diet consistent with vitamin K foods. Do not avoid these foods, but eat them regularly. Consistency is key!
- Avoid or limit your alcohol intake, no more than one drink per day, as a general rule. (One glass of wine, one beer or one ounce of hard liquor.)
- Be careful! Avoid injuries. If you cut or bump yourself, you will bruise or bleed more than you did before taking the medication.
