Two medicines, side by side

Bumetanide vs furosemide

Bumetanide and furosemide are both labeled for heart failure. Drugs@FDA records approvals of bumetanide since 1983 and of furosemide since 1966. Pharmacies paid $0.108 per bumetanide 1 mg tablet and $0.490 per mL (Furosemide 20 mg/2 mL vial) (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. Only the bumetanide label carries a boxed warning.

Check it at the source: the bumetanide FDA label on DailyMed (effective September 8, 2025); the furosemide FDA label on DailyMed (effective September 30, 2025).

Do their labels mention each other?

Bumetanide label, warnings

In these test animals bumetanide was 5 to 6 times more potent than furosemide and, since the diuretic potency of bumetanide is about 40 to 60 times furosemide, it is anticipated that blood levels necessary to produce ototoxicity will rarely be achieved.
