Contact your doctor immediately if you experience any of the following symptoms, as they may indicate an issue with your Coumadin level:
- Unexplained bleeding or bruising, including nosebleeds, bleeding gums, or heavy menstrual bleeding. Blood in your urine or stool. Sudden onset of weakness or dizziness. Severe headache. Changes in your vision. Shortness of breath. Unusual fatigue or lethargy.
Also, contact your doctor if:
- You experience any significant changes in your diet, such as starting or stopping a high-vitamin K diet. You begin or stop taking any new medications, including over-the-counter drugs, supplements, or herbal remedies. Many drugs interact with Coumadin. You have any significant health changes or illnesses, such as a major surgery or infection. Your INR test results are significantly above or below your target range. Your doctor will provide you with a specific range to aim for.
Understanding Your INR Range
Your doctor will determine your target INR range based on your specific medical condition. It’s crucial to understand this range and what constitutes a significant deviation. Regular monitoring is vital.
Frequency of INR Testing
The frequency of INR testing will vary depending on your individual needs and response to Coumadin. Discuss your testing schedule with your doctor to ensure appropriate monitoring. Don’t hesitate to ask questions if you are unsure about anything.
Keep a record of your INR results and any symptoms you experience. Communicate promptly with your healthcare provider about any concerns. Follow your doctor’s instructions diligently regarding medication and lifestyle adjustments.
