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 Ketoprofen label · effective 2026-04-02
Hydrochlorothiazide, given concomitantly with ketoprofen, produces a reduction in urinary potassium and chloride excretion compared to hydrochlorothiazide alone.
Patients at greatest risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics, and the elderly.
This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE-inhibitors.
Diuretics NSAIDs can reduce the natriuretic effect of furosemide and thiazides in some patients.
Patients taking diuretics are at a greater risk of developing renal failure secondary to a decrease in renal blood flow caused by prostaglandin inhibition (see PRECAUTIONS ).
