If INR is above 4 and urgent invasive treatment is needed, what should be done?

• A. Delay invasive treatment or refer if urgent
• B. Proceed as normal
• C. Reduce the anticoagulant dose but continue
• D. Switch to aspirin therapy

Answer: (A)

When INR is above 4, the blood’s ability to clot is significantly reduced, so invasive procedures carry a high risk of serious bleeding. In this situation the safest course is to delay the procedure if possible or, if the procedure must happen urgently, refer to a clinician who can manage anticoagulation properly and coordinate reversal or adjustment of therapy before proceeding. This approach prioritizes patient safety by restoring a safer hemostatic balance before an invasive step. Proceeding as normal ignores the elevated bleeding risk. Simply reducing the dose while continuing may not bring the INR down quickly enough to make the procedure safe. Switching to aspirin doesn’t solve the problem and can worsen bleeding risk or complicate management, especially since it doesn’t correct the anticoagulation status.
