Whether patients on warfarin can take acetaminophen
We're getting lots of calls about whether patients on warfarin can take acetaminophen. A new study in JAMA suggests that acetaminophen can increase the risk of bleeding.
This is a surprise to many people...they are accustomed to RECOMMENDING acetaminophen instead of aspirin to warfarin patients.
Patients taking just 4 regular-strength acetaminophen tablets a day, for a week, seem to be TEN times more likely to have a significant increase in INR.
