Dexamethasone + Ketorolac

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 increases the risk of gastrointestinal ulceration and bleeding; risk rises with higher doses, longer duration, advanced age, and prior GI disease.

Mechanism of action

Pharmacodynamic: additive inhibition of prostaglandin-mediated gastric mucosal protection by NSAIDs and corticosteroids; corticosteroids also impair mucosal healing. NSAID-related platelet dysfunction may further promote bleeding.

Clinical management

Avoid combination when possible. If necessary, use the lowest effective doses for the shortest duration, co-prescribe gastroprotection (e.g., PPI), avoid in patients with active or recent peptic ulcer/GI bleeding, and monitor for GI bleeding. Limit ketorolac therapy to a maximum of 5 days per labeling.
