Drug interactions
etoricoxib + venlafaxine
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
SNRIs impair platelet aggregation; combined with NSAIDs (including COX-2 inhibitors) increases risk of GI and other bleeding.
Mechanism of action
Pharmacodynamic: Venlafaxine depletes platelet serotonin (↓ aggregation) + NSAID-related GI mucosal injury → additive bleeding risk.
Clinical management
Avoid if high bleed risk. If needed, use lowest NSAID dose/duration; consider PPI gastroprotection; monitor for bleeding (bruising, melena, hematemesis) and CBC if prolonged use; avoid additional antithrombotics.
