Summary
Systemic corticosteroids can raise gastrointestinal bleeding risk and impair vascular integrity, which may add to the bleeding tendency of fondaparinux. The effect is mainly relevant with higher doses or prolonged steroid courses.
What this interaction means in plain words
Cortisone and Fondaparinux can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Corticosteroid-related mucosal and vascular fragility and gastric injury add to the anticoagulant effect on bleeding risk.
What to do
Watch for signs of bleeding, especially gastrointestinal, and consider gastroprotection when prolonged steroid therapy is needed. INR monitoring is not useful for fondaparinux.
