For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Overview
Increased risk of GI bleeding due to corticosteroid-related mucosal injury combined with clopidogrel’s antiplatelet effect.
Mechanism of action
Pharmacodynamic: corticosteroid-induced gastric mucosal damage plus P2Y12-mediated platelet inhibition → higher bleeding risk.
Clinical management
If coadministration is necessary, use lowest effective steroid dose and duration. Add PPI for GI protection in at‑risk patients; avoid additional NSAIDs/anticoagulants; monitor for bleeding (CBC, stool/occult blood).
