🩺 Clinical
Furosemide is used alone or with other medications to treat high blood pressure. Furosemide is used to treat edema excess fluid held in body tissues caused by various medical problems. Furosemide is in a class of medications called diuretics ('water pills'). It works by causing the kidneys to get rid of unneeded water and salt from the body. High blood pressure is a common condition. When not treated, it can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. This damage may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vi...

⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Fluid, Electrolyte, and Metabolic Abnormalities : Monitor serum electrolytes, CO 2 , BUN, creatinine, glucose, and uric acid. ( 5.1 ) Worsening Renal Function : Monitor for dehydration and azotemia. ( 5.2 ) Ototoxicity : Avoid higher than recommended doses.
( 5.3 , 7.1 ) Acute Urinary Retention : Monitor patients with symptoms of urinary retention. ( 5.4 ) Incomplete Dosing : Fluid contact and certain patient movements during treatment may cause the On-body Infusor to prematurely terminate infusion. Ensure patients can detect and respond to alarms.
( 5.5 )
5.1Fluid, Electrolyte, and Metabolic Abnormalities Furosemide may cause fluid, electrolyte, and metabolic abnormalities such as hypovolemia, hypokalemia, azotemia, hyponatremia, hypochloremic alkalosis, hypomagnesemia, hypocalcemia, hyperglycemia, or hyperuricemia, particularly in patients receiving higher doses, patients with inadequate oral electrolyte intake, and in elderly patients. Excessive diuresis may cause dehydration and blood volume reduction with circulatory collapse and possible vascular thrombosis and embolism, particularly in elderly patients.
Serum electrolytes, CO 2 , BUN, creatinine, glucose, and uric acid should be monitored frequently during furosemide therapy.
5.2Worsening Renal Function Furosemide can cause dehydration and azotemia. If increasing azotemia and oliguria occur during treatment of severe progressive renal disease, discontinue furosemide [see Clinical Pharmacology ( 12.3 )].
5.3Ototoxicity Cases of tinnitus and reversible or irreversible hearing impairment and deafness have been reported with furosemide. Reports usually indicate that furosemide ototoxicity is associated with rapid injection, severe renal impairment, the use of higher than recommended doses, hypoproteinemia or concomitant therapy with aminoglycoside antibiotics, ethacrynic acid, or other ototoxic drugs. If the physician elects to use high-dose parenteral therapy, controlled intravenous infusion is advisable (for adults, an infusion rate not exceeding 4 mg furosemide per minute has been used) [see Drug Interactions ( 7 )].
5.4Acute Urinary Retention In patients with severe symptoms of urinary retention (because of bladder emptying disorders, prostatic hyperplasia, urethral narrowing), the administration of furosemide can cause acute urinary retention related to increased production and retention of urine. These patients require careful monitoring, especially during the initial stages of treatment.
5.5Incomplete Dosing The Lasix ONYU Infusor should not come in contact with water or any other fluids (blood or drug product). Fluid contact with the Infusor circuit board can lead to device errors and premature termination of infusion. The Lasix ONYU is intended for use in a setting where the patient can limit their activity for the duration of administration.
Certain patient movements may cause interruption of device adherence to skin and premature termination of infusion. Lasix ONYU should only be used in patients who can detect and respond to alarms to ensure a complete dose is administered.
5.1Fluid, Electrolyte, and Metabolic Abnormalities Furosemide may cause fluid, electrolyte, and metabolic abnormalities such as hypovolemia, hypokalemia, azotemia, hyponatremia, hypochloremic alkalosis, hypomagnesemia, hypocalcemia, hyperglycemia, or hyperuricemia, particularly in patients receiving higher doses, patients with inadequate oral electrolyte intake, and in elderly patients. Excessive diuresis may cause dehydration and blood volume reduction with circulatory collapse and possible vascular thrombosis and embolism, particularly in elderly patients.
Serum electrolytes, CO 2 , BUN, creatinine, glucose, and uric acid should be monitored frequently during furosemide therapy.

🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following important adverse reactions are discussed elsewhere in the labeling: Fluid, Electrolyte, and Metabolic Abnormalities [see Warnings and Precautions ( 5.1 )]. Ototoxicity [see Warnings and Precautions ( 5.3 )] The following adverse reactions associated with the use of furosemide were identified in clinical trials or post-marketing reports. Because these reactions were reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency reliably, or to establish a causal relationship to drug exposure.
Adverse reactions are categorized below by organ system and listed by decreasing severity. Gastrointestinal System Reactions: pancreatitis, jaundice (intrahepatic cholestatic jaundice), increased liver enzymes, anorexia, oral and gastric irritation, cramping, diarrhea, constipation, nausea, vomiting. Systemic Hypersensitivity Reactions: severe anaphylactic or anaphylactoid reactions (e.g., with shock), systemic vasculitis, interstitial nephritis, necrotizing angiitis.
Central Nervous System Reactions: tinnitus and hearing loss, paresthesias, vertigo, dizziness, headache, blurred vision, xanthopsia. Hematologic Reactions: aplastic anemia, thrombocytopenia, agranulocytosis, hemolytic anemia, leukopenia, anemia, eosinophilia. Dermatologic Hypersensitivity Reactions: toxic epidermal necrolysis, Stevens-Johnson Syndrome, erythema multiforme, drug rash with eosinophilia and systemic symptoms, acute generalized exanthematous pustulosis, exfoliative dermatitis, bullous pemphigoid, purpura, photosensitivity, rash.
Cardiovascular Reactions: orthostatic hypotension, increase in cholesterol and triglyceride serum levels. Administration Site and Skin Reactions: erythema, bruising, edema, infusion site pain. Other Reactions: glycosuria, muscle spasm, weakness, restlessness, urinary bladder spasm, thrombophlebitis, transient injection site pain following intramuscular injection, fever.

Avoid combination. ( 7.1 ) Salicylates : Risk of salicylate toxicity. ( 7.1 ) Cisplatin and nephrotoxic drugs : Risk of ototoxicity and nephrotoxicity.
( 7.1 ) Lithium : Risk of lithium toxicity. ( 7.1 ) Renin-angiotensin inhibitors : Increased risk of hypotension and renal failure. ( 7.1 ) Adrenergic blocking drugs : Risk of potentiation.
( 7.1 ) Drugs undergoing renal tubular secretion : Risk of toxicity potentiation. ( 7.1 )
7.1Effects of Furosemide on Other Drugs Table 1: Effects of Furosemide on Other Drugs Drug/Substance Class or Name Drug Interaction Effect Recommendations Aminoglycoside antibiotics Furosemide may increase the ototoxic potential of aminoglycoside antibiotics, especially in the presence of impaired renal function [see Warnings and Precautions ( 5.3 )]. Avoid combination except in life-threatening situations. Ethacrynic acid Possibility of ototoxicity [see Warnings and Precautions ( 5.3 )].
Avoid concomitant use with ethacrynic acid. Salicylates May experience salicylate toxicity at lower doses because of competitive renal excretory sites. Monitor for symptoms of salicylate toxicity.
Cisplatin Cisplatin and nephrotoxic drugs There is a risk of ototoxic effects if cisplatin and furosemide are given concomitantly [see Warnings and Precautions ( 5.3 )]. Nephrotoxicity Administer furosemide at lower doses and with positive fluid balance when used to achieve forced diuresis during cisplatin treatment. Monitor renal function.
Paralytic agents Furosemide has a tendency to antagonize the skeletal muscle relaxing effect of tubocurarine and may potentiate the action of succinylcholine. Monitor for skeletal muscle effect. Lithium Furosemide reduces lithium’s renal clearance and adds a high-risk of lithium toxicity.
Avoid concomitant use with lithium. 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.
Antihypertensive drugs Furosemide may add to or potentiate the therapeutic effect of other antihypertensive drugs. Monitor for changes in blood pressure and adjust the dose of other antihypertensive drugs if needed. Adrenergic blocking drugs or peripheral adrenergic blocking drugs Potentiation occurs.
Monitor for changes in blood pressure and adjust the dose of adrenergic blocking drugs if needed. Norepinephrine Furosemide may decrease arterial responsiveness (vasoconstricting effect) to norepinephrine. Monitor blood pressure (or mean arterial pressure).
Chloral hydrate In isolated cases, intravenous administration of furosemide within 24 hours of taking chloral hydrate may lead to flushing, sweating attacks, restlessness, nausea, increase in blood pressure, and tachycardia. Concomitant use with chloral hydrate is not recommended. Methotrexate and other drugs undergoing renal tubular secretion Furosemide may decrease renal elimination of other drugs that undergo tubular secretion.
High-dose treatment of furosemide may result in elevated serum levels of these drugs and may potentiate their toxicity. Monitor serum levels of drugs undergoing renal tubular secretion and adjust the dose if needed. Cephalosporin Furosemide can increase the risk of cephalosporin-induced nephrotoxicity even in the setting of minor or transient renal impairment.
Monitor for changes in renal function. Cyclosporine Increased risk of gouty arthritis secondary to furosemide-induced hyperuricemia and cyclosporine impairment of renal urate excretion. Monitor serum urate levels.
Thyroid hormones High doses (> 80 mg) of furosemide may inhibit the binding of thyroid hormones to carri…
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Available data from published observational studies, case reports, and post marketing reports, from decades of use, have not demonstrated a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes with furosemide use during pregnancy. Untreated congestive heart failure can lead to adverse outcomes for the mother and the fetus (see Clinical Considerations). In animal reproduction studies, furosemide has been shown to cause unexplained maternal deaths and abortions in rabbits when administered orally during organogenesis at 4 times a human i.v. dose of 80 mg based on body surface area (BSA) and oral bioavailability corrections, presumably secondary to volume depletion (see Data).
The background risk for major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in the clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Clinical Considerations Disease-associated Maternal and/or Embryo/fetal Risk Pregnant women with congestive heart failure are at increased risk for pre-term birth. Stroke volume and heart rate increase during pregnancy, increasing cardiac output, especially during the first trimester. Clinical classification of heart disease may worsen with pregnancy and lead to maternal death and/or stillbirth.
Closely monitor pregnant patients for destabilization of their heart failure. Data Animal Data The effects of furosemide on embryonic and fetal development and on pregnant dams were studied in mice, rats, and rabbits. Furosemide caused unexplained maternal deaths and abortions in rabbits at the lowest dose of 25 mg/kg (approximately 4 times the human i.v. dose of 80 mg based on BSA and oral bioavailability corrections).
In another study, a dose of 50 mg/kg (approximately 7 times a human i.v. dose of 80 mg based on BSA and oral bioavailability corrections) also caused maternal deaths and abortions when administered to rabbits between Days 12 and 17 of gestation. In a third study, none of the pregnant rabbits survived an oral dose of 100 mg/kg. Data from the above studies indicate fetal lethality that can precede maternal deaths.
The results of the mouse study and one of the three rabbit studies also showed an increased incidence and severity of hydronephrosis (distention of the renal pelvis and, in some cases, of the ureters) in fetuses of treated dams as compared with the incidence of fetuses from the control group.
8.2Lactation Risk Summary The presence of furosemide has been reported in human breast milk. There are no data on the effects on the breastfed infant or the effects on milk production. Doses of furosemide associated with clinically significant diuresis may impair milk production.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for furosemide and any potential adverse effects on the breastfed infant from furosemide or from the underlying maternal condition.
8.4Pediatric Use Safety and efficacy for pediatric use have not been established [see Indications and Usage ( 1 )].
8.5Geriatric Use Controlled clinical studies did not include sufficient numbers of subjects to determine whether subjects aged 65 and over respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for the elderly patients should be cautious, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.
Lasix ONYU is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired…

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and efficacy for pediatric use have not been established [see Indications and Usage ( 1 )].
🧓 Geriatric Use ▾
8.5Geriatric Use Controlled clinical studies did not include sufficient numbers of subjects to determine whether subjects aged 65 and over respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for the elderly patients should be cautious, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.
Lasix ONYU is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function [see Clinical Pharmacology ( 12.3 )].
🆘 Overdosage ▾
10 OVERDOSAGE The principal signs and symptoms of overdose with Lasix ONYU are dehydration, blood volume reduction, hypotension, electrolyte imbalance, hypokalemia, and hypochloremic alkalosis, and are extensions of its diuretic action. The concentration of furosemide in biological fluids associated with toxicity or death is not known. Treatment of overdosage is supportive and consists of replacement of excessive fluid and electrolyte losses.
Serum electrolytes, carbon dioxide level, and blood pressure should be determined frequently. Adequate drainage must be assured in patients with urinary bladder outlet obstruction (such as prostatic hypertrophy). Hemodialysis does not accelerate furosemide elimination.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Furosemide primarily inhibits the reabsorption of sodium and chloride in the proximal and distal tubules and in the loop of Henle. The high degree of diuresis is largely due to the unique site of action. The action on the distal tubule is independent of any inhibitory effect on carbonic anhydrase and aldosterone.
12.2Pharmacodynamics In patients with NYHA Class II and Class III heart failure, subcutaneous administration of Lasix ONYU (30 mg furosemide over the first hour followed by 12.5 mg per hour for the subsequent 4 hours, total 80 mg furosemide within 5 hours) produced similar diuresis and natriuresis to intravenous administration (single 80 mg bolus) at 8- and 24-hour post-dose. The duration of diuretic effect with Lasix ONYU is at least 8 hours after initiation of dosing.
12.3Pharmacokinetics Absorption In patients with NYHA Class II and Class III heart failure, subcutaneous infusion of Lasix ONYU (30 mg furosemide over the first hour followed by 12.5 mg per hour for the subsequent 4 hours, 80 mg furosemide total), the bioavailability was 112% (90% CI: 104, 120%), with a median Tmax of 5 hours relative to 80 mg intravenous furosemide (single 80 mg bolus). The pharmacokinetic parameters of Lasix ONYU are presented in Table 3 below: Table 3: Pharmacokinetic Data of Lasix ONYU Following Subcutaneous Infusion (n = 18) Dose C max (ng/mL) Mean ± SD AUC t (ng×hr/mL) T 1/2 (hr) AUC ∞ (ng×hr/mL) Lasix ONYU: 30 mg subcutaneously infused over the first hour followed by 12.5 mg per hour for the subsequent 4 hours (total dose: 80 mg furosemide) 2010 ± 391 13000 ± 2510 3.7 ± 0.7 13100 ± 2550 Furosemide administered as single 80 mg bolus dose intravenously 13800 ± 4100 11900 ± 3380 3.7 ± 1.3 12000 ± 3400 The terminal half-life of furosemide is approximately 2 hours.
The impact of subcutaneous edema at the administration site of Lasix ONYU on drug absorption is unknown. Distribution Furosemide is extensively bound to plasma proteins, mainly to albumin. Plasma concentrations ranging from 1 mcg per mL to 400 mcg per mL are 91% to 99% bound in healthy individuals.
The unbound fraction averages 2.3% to 4.1% at therapeutic concentrations. Furosemide binding to albumin may be reduced in elderly patients. Elimination Significantly more furosemide is excreted in urine following the intravenous injection than after the tablet or oral solution.
Furosemide is predominantly excreted unchanged in the urine. The renal clearance of furosemide after intravenous administration in older healthy male subjects (60 to 70 years of age) is significantly less than in younger healthy male subjects (20 to 35 years of age). Metabolism Furosemide glucuronide is the only or at least the major biotransformation product of furosemide in humans.

📋 Description ▾
11 DESCRIPTION Lasix ONYU (furosemide injection) for subcutaneous use is a loop diuretic. Chemically, it is 4-chloro-N-furfuryl-5-sulfamoylanthranilic acid. Furosemide is a white to slightly yellow crystalline powder.
It is sparingly soluble in alcohol, freely soluble in dilute alkali solutions, and insoluble in dilute acids. The structural formula is as follows: Molecular Formula: C 12 H 11 ClN 2 O 5 S Molecular Weight: 330.75 g/mol Lasix ONYU is a single-dose prefilled cartridge co-packaged with a single-use Disposable Unit of the Infusor. The single-dose prefilled cartridge contains 80 mg furosemide in a 2.67 mL sterile, clear to slightly yellow, and nonpyrogenic aqueous solution.
The pH of Lasix ONYU, 7.5, differs from that of Furosemide Injection, USP. Each 1 mL dose of Lasix ONYU contains 30 mg of furosemide and the following inactive ingredients: betadex sulfobutyl ether sodium (300 mg), hydrochloric acid for pH adjustment if needed, sodium hydroxide for pH adjustment if needed, tromethamine (3 mg), and water for injection (q.s.). Each single-dose of Lasix ONYU is administered via an electromechanical (battery powered, microprocessor controlled) Infusor, pre-programmed to deliver 80 mg of Lasix ONYU over 5-hours using a bi-phasic delivery profile.
The Infusor consists of a custom Reusable Unit which can be used for close to 50 treatments. The Reusable Unit is used with a Disposable Unit and single-dose prefilled cartridge which are provided together for the user as a Lasix ONYU Kit. The Disposable Unit must be discarded after use. image-Structure
