Last updated
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.
Summary
Probenecid reduces ketorolac renal clearance, increasing ketorolac plasma levels and half-life. This raises the risk of ketorolac adverse effects such as bleeding, renal injury and GI ulceration; concomitant use is contraindicated in ketorolac labeling.
What this interaction means in plain words
Ketorolac intranasal and Probenecid are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Why it happens
Probenecid inhibits renal tubular anionic secretion of ketorolac, reducing its elimination.
What to do
Do not coadminister; choose a different analgesic or a non-probenecid urate-lowering approach.
