What the FDA labels say
From the Furosemide label · effective 2026-05-13
Angiotensin converting enzyme inhibitors or angiotensin II receptor blockers May lead to severe hypotension and deterioration in renal function, including renal failure.
Monitor for changes in blood pressure and renal function and interrupt or reduce the dosage of furosemide, angiotensin converting enzyme inhibitors, or angiotensin receptor blockers if needed.
Monitor for changes in blood pressure and adjust the dose of other antihypertensive drugs if needed.
From the Perindopril (Perindopril Erbumine) label · effective 2024-03-13
Symptomatic hypotension is most likely to occur in patients who have been volume or salt-depleted as a result of prolonged diuretic therapy, dietary salt restriction, dialysis, diarrhea or vomiting [see Dosage and Administration (2.1) ] .
Patients should be followed closely for the first two weeks of treatment and whenever the dose of perindopril erbumine and/or diuretic is increased.
Some perindopril erbumine-treated patients have developed minor and transient increases in blood urea nitrogen and serum creatinine especially in those concomitantly treated with a diuretic.
Risk factors for the development of hyperkalemia include renal insufficiency, diabetes mellitus and the concomitant use of agents such as potassium-sparing diuretics, potassium supplements and/or potassium-containing salt substitutes [see Drug Interactions (7.2) ] .
Potassium-Sparing Diuretics/Potassium Supplements: Hyperkalemia.
