Drug interactions
Celecoxib + Naproxen
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
Concomitant use of two NSAIDs increases risk of serious gastrointestinal bleeding/ulceration, acute kidney injury, fluid retention/hypertension, and overall NSAID-related adverse effects without added analgesic benefit.
Mechanism of action
Pharmacodynamic additive COX-1/COX-2 inhibition leading to reduced protective prostaglandins in GI mucosa and kidneys; promotes mucosal injury, decreased renal perfusion, sodium/water retention, and elevated blood pressure. No meaningful pharmacokinetic interaction.
Clinical management
Avoid concurrent use; select a single NSAID. If unavoidable for a brief period, use the lowest effective doses for the shortest duration, add gastroprotection (e.g., PPI) in high-risk patients, and monitor for GI bleeding, serum creatinine/eGFR, and blood pressure.
