Drug interactions
Diclofenac + Escitalopram
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 bleeding, particularly upper gastrointestinal bleeding, when escitalopram (SSRI) is combined with diclofenac (NSAID).
Mechanism of action
Pharmacodynamic: SSRIs reduce platelet serotonin uptake and impair aggregation; NSAIDs cause gastric mucosal injury and reversible platelet dysfunction via COX inhibition, producing additive bleeding risk. No meaningful pharmacokinetic interaction is expected.
Clinical management
Avoid routine concomitant use when possible. If combination is necessary, use the lowest effective NSAID dose for the shortest duration and consider PPI gastroprotection, especially in high‑risk patients (age >65, prior ulcer/GI bleed, concomitant anticoagulants/antiplatelets/corticosteroids). Counsel on bleeding symptoms and monitor (stool guaiac/melena, hemoglobin/hematocrit if prolonged therapy). Prefer non‑NSAID analgesics (e.g., acetaminophen) or topical NSAID when appropriate.
