Gail's experience is exactly why I do not get excited about INRs that are less than 8. She may have had a TIA as a result of holding these warfarin doses. Much better to risk a bloody nose than paralysis. It just seems like such a simple concept that so many people in the health care business cannot seem to grasp.
The rule of thumb is that if someone takes warfarin 5 mg daily, the INR will drop by half every 48 hours. If you take more than 5 mg the drop will be faster. If you take less than 5 mg the drop will be slower.
Gail's INR going to 1.3 is just a little more of a drop than what should have been expected. After 2 days the average 7.2 INR would drop to about 3.6. But she takes almost twice as much warfarin as "average". So a 1 day hold would have produced about a 3.6 and holding another day would have produced about a 1.8. I think that her warfarin manager should have known that they were putting her at risk of a stroke. Remember that she was not bleeding. She had no problem except a high INR number. Shewas worried at being at deaths door. I don't think she was but her warfarin manager tried to kick the door down.
