What the FDA labels say
From the Benazepril and hydrochlorothiazide (Lotensin HCT) label · effective 2026-02-24
NSAIDs and Cox-2 selective agents: In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function, coadministration of NSAIDs, including selective COX-2 inhibitors, with ACE inhibitors, including benazepril, may result in deterioration of renal function, including possible acute renal failure.
Monitor renal function periodically in patients receiving benazepril and NSAID therapy.
The antihypertensive effect of benazepril and hydrochlorothiazide may be attenuated by NSAIDs.
From the Ketorolac (Ketorolac Tromethamine) label · effective 2024-12-31
Patients at greatest risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors, and the elderly.
Diuretics Clinical studies, as well as postmarketing observations, have shown that ketorolac tromethamine can reduce the natriuretic effect of furosemide and thiazides in some patients.
ACE Inhibitors/Angiotensin II Receptor Antagonists Concomitant use of ACE inhibitors and/or angiotensin II receptor antagonists may increase the risk of renal impairment, particularly in volume-depleted patients.
This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE inhibitors and/or angiotensin II receptor antagonists.
Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs.
