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

Severity: Major · Evidence level: High

Concurrent use of two NSAIDs increases risk of GI bleeding/ulceration, acute kidney injury, and BP/CV adverse events without added analgesic benefit.

Mechanism of action

Additive COX-1/2 inhibition → reduced gastric/renal prostaglandins → ↑ GI mucosal injury and renal hypoperfusion; additive effects on BP/CV risk.

Clinical management

Avoid dual NSAID therapy. Use a single NSAID at the lowest effective dose/shortest duration. If unavoidable, add PPI for GI protection in at‑risk patients and monitor renal function, BP, and signs of bleeding.
