minor Known Drug Interaction
Use of lisinopril with potassium-sparing diuretics (e.g., spironolactone, eplerenone, triamterene, or amiloride), potassium supplements, or potassium-containing salt substitutes may lead to significant increases in serum potassium.
Inspra
Dyazide, Maxzide
Eplerenone (Inspra) helps you live longer if you have heart failure after a heart attack. It also lowers blood pressure if you have high blood pressure.

Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, eplerenone has 4,445 submissions while hydrochlorothiazide/triamterene has 43,279. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone.
