What the FDA labels say
From the Eplerenone label · effective 2025-06-23
…• serum creatinine > 2.0 mg/dL in males or >1.8 mg/dL in females, • creatinine clearance < 50 mL/min, or • concomitant administration of potassium supplements or potassium-sparing diuretics (e.g., amiloride, spironolactone, or triamterene) [see Warnings and Precautions (5.1) , Adverse Reactions (6.2) , Drug Interactions (7) , and Clinical Pharmacology (12.3)…
• Concomitant use of potassium supplements or potassium-sparing diuretics ( 4 )
Lithium toxicity has been reported in patients receiving lithium concomitantly with diuretics and ACE inhibitors.
The administration of other potassium-sparing antihypertensives with NSAIDs has been shown to reduce the antihypertensive effect in some patients and result in severe hyperkalemia in patients with impaired renal function.
From the Indapamide label · effective 2026-05-13
Hypokalemia occurs commonly with diuretics (see ADVERSE REACTIONS ), and electrolyte monitoring is essential, particularly in patients who would be at increased risk from hypokalemia, such as those with cardiac arrhythmias or who are receiving concomitant cardiac glycosides.
In general, diuretics should not be given concomitantly with lithium because they reduce its renal clearance and add a high risk of lithium toxicity.
Drug Interactions Other Antihypertensives: Indapamide may add to or potentiate the action of other antihypertensive drugs.
In limited controlled trials that compared the effect of indapamide combined with other antihypertensive drugs with the effect of the other drugs administered alone, there was no notable change in the nature or frequency of adverse reactions associated with the combined therapy.
