Bumetanide is a potent diuretic which, if given in excessive amounts, can lead to a profound diuresis with water and electrolyte depletion. Therefore, careful medical supervision is required and dose and dosage schedule have to be adjusted to the individual patient's needs.
Dosage guidance:
Clinical considerations: Relative to other loop diuretics (eg, furosemide), bumetanide is much more potent; monitor closely during use. Dose equivalency for adult patients with normal renal function (approximate): Bumetanide 1 mg = furosemide 40 mg (Ref).
Edema (diuresis): Limited data available: Note: Doses in the higher end of the range may be required for patients with heart failure (Ref):
Preterm neonates: Oral, IM, IV: 0.01 to 0.06 mg/kg/dose every 12 to 48 hours; every 12 to 24 hour dosing interval has been used for oliguria in the setting of acute renal failure (Ref); IV and oral doses up to 0.1 mg/kg/dose are recommended (Ref).
Term neonates: Oral, IM, IV: Usual dose: 0.01 to 0.05 mg/kg/dose every 12 to 24 hours; reported dosage range: 0.005 to 0.1 mg/kg/dose (Ref). Note: A dose of 0.1 mg/kg/dose has been shown effective in neonates on extracorporeal membrane oxygenation (Ref).
Dosage guidance:
Dosing: Dose equivalency for adult patients with normal renal function (approximate): Bumetanide 1 mg = furosemide 40 mg = torsemide 10 to 20 mg. Note: Ethacrynic acid has a relative potency of 0.7 (Ref).
Edema (diuresis):
Intermittent dosing:
Infants and Children: Limited data available: Oral, IM, IV: 0.01 to 0.1 mg/kg/dose every 6 to 24 hours; maximum adult daily dose: 10 mg/day; a prospective, open-label dose-range study in infants (mean age: 2 months; range: 0 to 6 months) reported a maximal diuretic response at doses 0.035 to 0.04 mg/kg/dose every 6 to 8 hours, and no additional clinical benefit (ie, urine output) at doses >0.05 mg/kg/dose (Ref).
Adolescents: Very limited data: Oral, IM, IV: Initial: 0.5 to 1 mg/dose every 6 to 24 hours; maximum adult daily dose: 10 mg/day. Note: Dosing in adolescents based on experience in adult patients.
Continuous IV infusion: Limited data available: Infants, Children, and Adolescents ≤16 years: 1 to 10 mcg/kg/hour; titrate to effect (Ref). Note: A wide range of doses (1 to 200 mcg/kg/hour) have been reported; a complete safety analysis is lacking for the higher doses (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
There are no dosage adjustment provided in the manufacturer's labeling; based on experience in adult patients, high doses are effective in end-stage kidney disease (Ref), but use is contraindicated in anuria; use with caution in kidney insufficiency due to increased risk of adverse effects.
There are no dosage adjustments provided in the manufacturer's labeling; based on experience in adult patients, use is contraindicated in hepatic coma. Use with caution in cirrhosis and ascites due to increased risk of precipitating hepatic coma; initiate with conservative doses and monitoring.
(For additional information see "Bumetanide: Drug information")
Dosage guidance:
Dosing: Loop diuretic approximate oral dose equivalency for patients with normal kidney function: Bumetanide 1 mg = furosemide 40 mg = torsemide 10 to 20 mg (Ref).
Edema or volume overload:
Naive to loop diuretics:
Oral, IV: Initial: 0.5 to 1 mg once, then titrate as needed to an effective dose (see Titration to Effect below) (Ref).
Note: Oral bioavailability is very good (~80% to 100%); the same IV or oral dose is expected to produce a similar effect (Ref).
Refractory edema or acute decompensation in patients taking oral loop diuretics:
IV: Bolus/intermittent dosing: Initial: Administer 1 to 2.5 times the total daily oral maintenance dose once (eg, a patient taking oral bumetanide 1 mg twice daily at home [2 mg/day] can be given 2 to 5 mg IV as an initial bolus), then titrate as needed to an effective dose; maximum effective single dose: 3 to 10 mg depending on kidney function (see "Titration to Effect" below) (Ref).
Titration to effect: If the initial dose does not result in diuresis, double the individual dose (rather than administer the same dose more frequently) until diuresis occurs. Titration of an IV dose can occur at ≥2-hour intervals as needed in hospitalized patients. Once an effective dose is identified, it is typically administered 1 to 3 times daily. The maximum effective dose varies by population; higher than usual doses may be required for patients with nephrotic syndrome or kidney failure; maximum effective single dose: 3 to 10 mg; maximum recommended total daily dose: 10 mg/day (Ref).
Continuous infusion: Note: Reserve for patients who have responded to bolus therapy but need ongoing and sustained diuresis; administer an effective bolus dose then immediately start continuous infusion.
IV: Initial: 0.5 mg/hour; if diuretic response is not adequate, repeat IV bolus dose and increase continuous infusion to 1 mg/hour; continue to bolus and titrate infusion as needed up to 2 mg/hour (Ref).
Note: Higher continuous infusion rates are not recommended due to potential for side effects; consider alternative strategies for fluid removal (Ref).
Transitioning from IV to oral: Give the same IV dose orally (eg, total daily IV dose of 3 mg/day should be converted to an oral dose of 3 mg/day in 1 to 3 divided doses), then monitor urine output and adjust oral dose as needed (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Altered kidney function: IV, Oral:
eGFR ≥30 mL/minute/1.73 m2: No dosage adjustment necessary (Ref).
eGFR <30 mL/minute/1.73 m2:
Higher doses may be required to achieve desired diuretic response due to decreased secretion into the tubular fluid. However, single IV or oral doses >8 to 10 mg are unlikely to result in additional diuretic effect (Ref).
Continuous infusion: IV: Initial: 1 mg/hour; if diuretic response is not adequate, repeat IV bolus dose and increase continuous infusion to 2 mg/hour (Ref).
Hemodialysis, intermittent (thrice weekly): Unlikely to be significantly dialyzable (highly protein bound) (Ref):
IV, Oral:
Patients with anuria: Use is contraindicated (Ref).
Patients with residual kidney function: Dose as per eGFR <30 mL/minute/1.73 m2 (Ref).
Peritoneal dialysis: Unlikely to be significantly dialyzable (highly protein bound) (Ref):
IV, Oral:
Patients with anuria: Use is contraindicated (Ref).
Patients with residual kidney function: Dose as per eGFR <30 mL/minute/1.73 m2 (Ref).
CRRT: Drug clearance is dependent on the effluent flow rate, filter type, and method of renal replacement. Recommendations are based on high-flux dialyzers and effluent flow rates of 20 to 25 mL/kg/hour (or ~1,500 to 3,000 mL/hour) unless otherwise noted.
IV, Oral: In general, use not recommended; fluid management can be more effectively managed using CRRT ultrafiltration (Ref).
PIRRT (eg, sustained, low-efficiency diafiltration): Drug clearance is dependent on the effluent flow rate, filter type, and method of renal replacement. Close monitoring of response and adverse reactions (eg, ototoxicity) due to drug accumulation is important.
IV, Oral:
Patients with anuria: There is no expected clinical benefit; use is not recommended (Ref).
Patients with residual kidney function: Dose as per eGFR <30 mL/minute/1.73 m2 (Ref).
There are no dosage adjustments provided in the manufacturer’s labeling. Use is contraindicated in hepatic coma. Use with caution in cirrhosis and ascites due to increased risk of precipitating hepatic coma; initiate with conservative doses and monitoring.
Loop diuretics, including bumetanide, may lead to acute kidney injury due to fluid loss.
Mechanism: Dose-related; related to the pharmacologic action (ie, volume depletion) (Ref).
Risk factors:
• Excessive doses (Ref)
• Concurrent administration of nephrotoxic agents (Ref)
• Older adults (Ref)
• Preexisting volume depletion (Ref)
• Reduced blood flow to the kidney or depletion of effective blood volume (eg, bilateral renal artery stenosis, cirrhosis, nephrotic syndrome, heart failure) (Ref)
Loop diuretics, including bumetanide, may lead to profound diuresis (especially if given in excessive amounts), resulting in hypovolemia and electrolyte loss. Electrolyte disturbances (eg, hypocalcemia, hypokalemia, hypomagnesemia) may predispose a patient to serious cardiac arrhythmias.
Mechanism: Dose-related; related to the pharmacologic action (Ref).
Risk factors:
• Excessive doses with initiation or dose adjustment (Ref)
• Reduced dietary fluid and/or electrolyte intake (Ref)
• Concurrent illness leading to excessive fluid loss (eg, diarrhea, vomiting) (Ref)
• Concomitant administration of an additional diuretic (Ref)
• Very high or very restricted dietary sodium (Ref)
Immediate hypersensitivity reactions, including urticaria, have been reported (Ref) with bumetanide. Delayed hypersensitivity reactions range from nonspecific skin rash to rare severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome and toxic epidermal necrolysis.
Mechanism: Non–dose-related; immunologic. Immediate hypersensitivity reactions: IgE-mediated, with specific antibodies formed against a drug allergen following initial exposure (Ref). SCARs: Delayed type IV hypersensitivity reactions involving a T-cell mediated drug-specific immune response (Ref).
Onset: Immediate hypersensitivity reactions: Rapid; generally occurs within 1 hour of administration but may occur up to 6 hours after exposure (Ref). Delayed hypersensitivity reactions: Varied; typically occur 1 to 8 weeks after drug exposure but may occur more rapidly (usually within 1 to 4 days) upon reexposure (Ref).
Loop diuretics, including bumetanide, have been associated with hearing loss (deafness) and tinnitus, which is generally reversible (lasting from 30 minutes to 24 hours after administration) (Ref). There is less risk of ototoxicity with bumetanide compared to furosemide (Ref).
Mechanism: Dose-related; related to the pharmacologic action (ie, inhibition of a secretory isoform of the Na-K-2Cl co-transporter in the inner ear and impacts on ionic composition of cochlear fluids) (Ref).
Risk factors:
• Concurrent kidney disease (Ref)
• Excessive doses (Ref)
• IV administration (Ref): bolus (higher risk) versus continuous infusion (Ref)
• Concurrent use of other ototoxic agents (eg, aminoglycosides) can lead to ototoxicity at lower doses (Ref)

Hypersensitivity to bumetanide or any component of the formulation; anuria; hepatic coma; patients in states of severe electrolyte depletion until the condition improves or is corrected.
Canadian labeling: Additional contraindications (not in US labeling): Hypersensitivity to other sulfonamide derivatives; hepatic encephalopathy; galactose intolerance, glucose-galactose malabsorption, or congenital lactase deficiency.
Note: Although the FDA-approved product labeling states this medication is contraindicated in patients with hypersensitivity to sulfonamide-containing drugs, the scientific basis of this cross-sensitivity has been challenged.
Concerns related to adverse effects:
• Hyperuricemia: Asymptomatic hyperuricemia has been reported with use.
• Sulfonamide (“sulfa”) allergy: The FDA-approved product labeling for many medications containing a sulfonamide chemical group includes a broad contraindication in patients with a prior allergic reaction to sulfonamides. There is a potential for cross-reactivity between members of a specific class (eg, two antibiotic sulfonamides). However, concerns for cross-reactivity have previously extended to all compounds containing the sulfonamide structure (SO2NH2). An expanded understanding of allergic mechanisms indicates cross-reactivity between antibiotic sulfonamides and nonantibiotic sulfonamides may not occur or at the very least this potential is extremely low (Brackett 2004; Johnson 2005; Slatore 2004; Tornero 2004). In particular, mechanisms of cross-reaction due to antibody production (anaphylaxis) are unlikely to occur with nonantibiotic sulfonamides. T-cell-mediated (type IV) reactions (eg, maculopapular rash) are not well understood and it is not possible to completely exclude this potential based on current insights. In cases where prior reactions were severe (Stevens-Johnson syndrome/TEN), some clinicians choose to avoid exposure to these classes.
Disease-related concerns:
• Bariatric surgery: Dehydration: Avoid diuretics in the immediate postoperative period after bariatric surgery; electrolyte disturbances and dehydration may occur. Diuretics may be resumed, if indicated, once oral fluid intake goals are met (Ziegler 2009).
• Hepatic impairment: Use caution in patients with cirrhosis; initiate bumetanide therapy with conservative dosing and close monitoring of electrolytes; avoid sudden changes in fluid and electrolyte balance and acid/base status which may lead to hepatic encephalopathy.
• Kidney impairment: Larger doses may be necessary in patients with impaired kidney function to obtain the same therapeutic response (Brater 1998).
Special populations:
• Neonates: In vitro studies using pooled sera from critically-ill neonates have shown bumetanide to be a potent displacer of bilirubin; avoid use in neonates at risk for kernicterus.
• Surgical patients: If given the morning of surgery, bumetanide may render the patient volume depleted and blood pressure may be labile during general anesthesia.
Dosage form specific issues:
• Benzyl alcohol and derivatives: Some dosage forms may contain benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity (“gasping syndrome”) in neonates; the “gasping syndrome” consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension and cardiovascular collapse (AAP ["Inactive" 1997]; CDC 1982); some data suggests that benzoate displaces bilirubin from protein binding sites (Ahlfors 2001); avoid or use dosage forms containing benzyl alcohol with caution in neonates. See manufacturer's labeling.
Other warnings and precautions:
• Diuretic resistance: For some patients, despite high doses of loop diuretic, an adequate diuretic response cannot be attained. Diuretic resistance may be overcome by IV rather than oral administration or the use of 2 diuretics together (eg, a loop diuretic in combination with a thiazide diuretic). When such combinations are used, serum electrolytes need to be monitored even more closely (ACC [Hollenberg 2019]).
