Two different mechanisms

Some medicines affect how a DOAC is transported or metabolised, including through P-glycoprotein or CYP pathways. Others add to bleeding risk through their effects on haemostasis. These mechanisms are not interchangeable.

Look in both directions

An interaction can increase anticoagulant exposure and bleeding risk, or reduce exposure and compromise protection against thrombosis. The implications differ between drugs, so class-wide assumptions can be misleading.

Review the complete picture

Include prescribed medicines, non-prescription products and supplements. A clinical review considers the exact combination, indication, renal function and alternatives, with a pharmacist or specialist when needed. An interaction alert is a starting point for interpretation, not a complete treatment decision.

The key idea

Check the specific medicine pair and its clinical context against a current, reliable reference.
