possible interaction between warfarin and acetaminophen
April 1998
The latest news about a possible interaction between warfarin and acetaminophen is taking lots of people bysurprise.
For years we've told warfarin patients not to take aspirin or NSAIDs. We told them to take acetaminopheninstead...to avoid a possible drug interaction.
But now a new study suggests that acetaminophen also increases the risk of bleeding in warfarin patients. Infact, the chance of a significant increase in INR increases TEN-fold in patients who take as few as 4 regular-strength acetaminophen tabs daily for a week.
