Warfarin and Other Blood Thinners for Heart Disease
When Should I Call my Doctor?
If you take warfarin, call your doctor if you notice any of the following signs of bleeding or illness that can affect the way your warfarin works:
- Feeling more weak or tired than usual or looking pale (symptoms of anemia).
- Bleeding from cuts that won't stop after applying pressure for 10 minutes.
Coughing or vomiting blood (which may look like coffee grounds).
- Bleeding from the nose, gums, or ears.
- Unusual color of the urine or stool (including dark brown urine, or red or black, tarry stools).
- Unusual bruising (black and blue marks on your skin) for unknown reasons.
- Menstrual bleeding that is heavier or lasts longer than normal.
- A fever or illness that gets worse.
- A serious fall or a blow to the head.
- Unusual pain or swelling.
- Unusual headache.
- Difficulty breathing.
If you notice any of these symptoms, your doctor may want to do a blood test, stop the warfarin or prescribe medication to stop the bleeding.
Also contact your doctor if you have any other symptoms that cause concern.
