Summary
Corticosteroids can contribute to bleeding through gastric mucosal injury and vascular fragility, which adds to the bleeding risk of heparin. The effect is generally modest but relevant with high steroid doses or other risk factors.
What this interaction means in plain words
Heparin and Prednisolone 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.
Heparin belongs to Cardiovascular; Prednisolone belongs to Endocrine.
Why it happens
Additive bleeding risk from corticosteroid-related mucosal and vascular effects together with anticoagulation.
What to do
Monitor aPTT or anti-Xa as appropriate and watch for bleeding. Consider gastroprotection in patients at risk.
