Furosemide (Lasix) is a loop diuretic, a strong “water pill” that stops the kidneys from reabsorbing salt so salt and water leave in the urine, and it is the most widely used drug for fluid buildup from heart failure, cirrhosis and kidney disease (it also treats high blood pressure), on the market since about 1966 and available as a generic. Most people handle it well, mainly noticing frequent urination soon after each dose and lightheadedness when standing up. Its boxed warning is that too much can drain water and body salts (electrolytes) dangerously, so report severe dizziness, fainting, extreme weakness, very little urine or any ringing in the ears right away.
Clinical pearls
- Take it in the morning, and any second dose by mid-afternoon, so the extra urination does not keep you up at night.
- Expect regular blood tests for potassium, sodium and kidney function, because furosemide flushes out body salts along with the water.
- If you take lithium, make sure every prescriber knows, since furosemide can push lithium to toxic levels.
- Weigh yourself each morning, because a quick gain or drop shows whether the dose is pulling off too little fluid or too much.

What Furosemide is used for
▾
Furosemide treats fluid buildup and, in oral forms, high blood pressure. Uses vary by product.
- Edema from congestive heart failure, cirrhosis of the liver, and kidney disease including nephrotic syndrome: Lasix, furosemide tablets, oral solution and injection (adults and children).
- High blood pressure in adults, alone or with other medicines: oral furosemide and Lasix tablets.
- Add-on treatment for acute pulmonary edema: furosemide injection.
- Edema in adults with chronic heart failure or chronic kidney disease, and in children 43 kg and above: Furoscix, subcutaneous.
- Edema in adults with chronic heart failure: Lasix Onyu, subcutaneous.
How Furosemide works
▾
Furosemide acts on the kidney’s filtering tubes, mainly the loop of Henle. It blocks reabsorption of sodium and chloride, so more salt and water leave in the urine. Its action on the distal tubule does not depend on carbonic anhydrase or aldosterone.
Furosemide dosage
▾
Dosing is tailored to your response, aiming for the lowest dose that keeps swelling controlled.
- Tablets and oral solution: swallowed, usually once or twice daily. Some people use them only on certain days each week.
- Injection: given IV or IM only when you cannot take oral medicine or in emergencies, then switched to oral.
- Furoscix and Lasix Onyu: given under the skin and not for long-term use.
Follow your prescriber and product label.
Dosing details from the FDA-approved label

Read the label’s full dosing text
DOSAGE AND ADMINISTRATION Edema Therapy should be individualized according to patient response to gain maximal therapeutic response and to determine the minimal dose needed to maintain that response. Adults - The usual initial dose of furosemide tablets is 20 to 80 mg given as a single dose. Ordinarily a prompt diuresis ensues. If needed, the same dose can be administered 6 to 8 hours later or the dose may be increased. The dose may be raised by 20 or 40 mg and given not sooner than 6 to 8 hours after the previous dose until the desired diuretic effect has been obtained. The individually determined single dose should then be given once or twice daily (e.g., at 8 am and 2 pm). The dose of furosemide tablets may be carefully titrated up to 600 mg/day in patients with clinically severe edematous states. Edema may be most efficiently and safely mobilized by giving furosemide tablets on 2 to 4 consecutive days each week. When doses exceeding 80 mg/day are given for prolonged periods, careful clinical observation and laboratory monitoring are particularly advisable (see PRECAUTIONS: Laboratory Tests ). Geriatric Patients - In general, dose selection for the elderly patient should be cautious, usually starting at the low end of the dosing range (see PRECAUTIONS: Geriatric Use ). Pediatric Patients - The usual initial dose of oral furosemide in pediatric patients is 2 mg/kg body weight, given as a single dose. If the diuretic response is not satisfactory after the initial dose, dosage may be increased by 1 or 2 mg/kg no sooner than 6 to 8 hours after the previous dose. Doses greater than 6 mg/kg body weight are not recommended. For maintenance therapy in pediatric patients, the dose should be adjusted to the minimum effective level. Hypertension Therapy should be individualized according to the patient's response to gain maximal therapeutic response and to determine the minimal dose needed to maintain the therapeutic response. Adults - The usual initial dose of furosemide tablets for hypertension is 80 mg, usually divided into 40 mg twice a day. Dosage should then be adjusted according to response. If response is not satisfactory, add other antihypertensive agents. Changes in blood pressure must be carefully monitored when furosemide tablets are used with other antihypertensive drugs, especially during initial therapy.

Furosemide interactions
▾
Furosemide can interact with many medicines.
- Aminoglycoside antibiotics and ethacrynic acid: hearing damage risk
- Lithium: can reach toxic levels
- ACE inhibitors, ARBs and other blood pressure drugs: blood pressure may drop too far
- Salicylates: toxicity at lower doses
- Cisplatin and cephalosporins: kidney and hearing risks
- Indomethacin and phenytoin: weaker furosemide effect
- Methotrexate and similar drugs: levels may rise
- Cyclosporine: higher gout risk
- Chloral hydrate with IV furosemide: flushing, sweating, fast heartbeat
Interactions listed in the FDA-approved label
From the Furosemide prescribing information (“Drug Interactions”): what the manufacturer studied or reported to the FDA.
- Aminoglycoside antibiotics: Furosemide may increase the ototoxic potential of aminoglycoside antibiotics, especially in the presence of impaired renal function. Avoid combination except in life-threatening situations.
- Ethacrynic acid: Possibility of ototoxicity. 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 and nephrotoxic drugs: There is a risk of ototoxic effects if cisplatin and furosemide are given concomitantly; 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).

Drug Interactions Furosemide may increase the ototoxic potential of aminoglycoside antibiotics, especially in the presence of impaired renal function. Except in life-threatening situations, avoid this combination. Furosemide should not be used concomitantly with ethacrynic acid because of the possibility of ototoxicity. Patients receiving high doses of salicylates concomitantly with furosemide, as in rheumatic disease, may experience salicylate toxicity at lower doses because of competitive renal excretory sites. There is a risk of ototoxic effects if cisplatin and furosemide are given concomitantly. In addition, nephrotoxicity of nephrotoxic drugs such as cisplatin may be enhanced if furosemide is not given in lower doses and with positive fluid balance when used to achieve forced diuresis during cisplatin treatment. Furosemide has a tendency to antagonize the skeletal muscle-relaxing effect of tubocurarine and may potentiate the action of succinylcholine. Lithium generally should not be given with diuretics because they reduce lithium's renal clearance and add a high risk of lithium toxicity. Furosemide combined with angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers may lead to severe hypotension and deterioration in renal function, including renal failure. An interruption or reduction in the dosage of furosemide, angiotensin-converting enzyme inhibitors, or angiotensin receptor blockers may be necessary. Potentiation occurs with ganglionic or peripheral adrenergic blocking drugs. Furosemide may decrease arterial responsiveness to norepinephrine. However, norepinephrine may still be used effectively. Simultaneous administration of sucralfate and furosemide tablets may reduce the natriuretic and antihypertensive effects of furosemide. Patients receiving both drugs should be observed closely to determine if the desired diuretic and/or antihypertensive effect of furosemide is achieved.

Before taking Furosemide
▾
- Do not use Furoscix if you cannot make urine or are allergic to furosemide or its ingredients.
- Do not use the Furoscix On-body Infusor if you are allergic to medical adhesives.
- Tell your doctor about liver cirrhosis, kidney disease or bladder emptying problems.
- Pregnancy: tell your doctor; observational data have not shown a clear risk of birth defects, but animal studies showed harm in rabbits.
- Breastfeeding: furosemide is in breast milk and may lower milk production at higher doses.
- Children: Furoscix On-body Infusor is for those 43 kg and above; Furoscix ReadyFlow has not been established for children.
- Older adults: more likely to have fluid and electrolyte problems.
Furosemide overdose
▾
Too much furosemide causes dehydration, low blood volume, low blood pressure and electrolyte imbalances. Treatment is supportive: replacing lost fluid and electrolytes, with frequent monitoring. Hemodialysis does not speed up elimination.
What Furosemide does in the body
▾
After IV injection, diuresis (increased urine output) begins within 5 minutes, and later after IM injection. The effect peaks within the first half hour and lasts about 2 hours. For Furoscix, the effect lasts up to 6 hours with the ReadyFlow and up to 8 hours with the On-body Infusor.
How your body processes Furosemide
▾
Furosemide binds heavily to blood proteins, mainly albumin. Its half-life is about 2 hours. The body mainly clears it unchanged in urine, with glucuronide as the main metabolite. More is excreted in urine after IV injection than after tablets or oral solution. In older adults, albumin binding and kidney clearance are reduced, and the initial diuretic effect is weaker.
How to store Furosemide
▾
Store at 68° to 77°F (20° to 25°C); excursions permitted to 59° to 86°F (15° to 30°C) .

How widely Furosemide is used (Medicaid data)
A general measure of how commonly Furosemide is prescribed, based on Medicaid — one of the largest public drug programs. The figure below is prescriptions filled in Q1–Q4 2025, summed across every form and brand of the drug.
Think of this as a proxy for how widely Furosemide is used, drawn from freely available public data. Medicaid is just one program — these numbers don’t include Medicare, other government coverage, or commercial and cash-pay prescriptions, so real-world use is higher than what’s shown here.
How commonly is Furosemide prescribed? Of the 1,601 medications we measure, Furosemide ranks #84 by Medicaid prescriptions — more than 95% of them.

Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.
Source: Medicaid State Drug Utilization Data (CMS), aggregated by generic ingredient — summed across every NDC (all brands, strengths, salt forms and dosage forms) of Furosemide, and across all states and both fee-for-service and managed-care claims. A general popularity signal; it excludes Medicare, commercial insurance and cash prescriptions, so it is not total U.S. use. Based on the 79 of 833 listed Furosemide NDCs with Medicaid activity.

Furosemide side effects reported to the FDA (FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Furosemide — a signal of what to watch for, not proof the drug caused it.
The effects most often named in FDA reports that mention Furosemide are dyspnoea, fatigue, diarrhoea; about 81% of the reports were classed as serious. These are voluntary reports, so they show what people report, not how often it happens.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Furosemide in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.
Furosemide FDA approval history
How Furosemide went from FDA review to the pharmacy shelf — the key milestones in its regulatory journey.
Furosemide was first approved by the FDA in 1966 (Brand: LASIX · Validus Pharms); the first generic version was approved in 1985. It remains available in U.S. pharmacies today.

Furosemide recall history
A recall is when a specific batch of a medicine is pulled from the market — usually a manufacturing issue, not a problem with the drug itself. Class I is most serious, Class III least.
The FDA’s enforcement reports list 2 Furosemide recalls since July 2021. Both are still ongoing or began in the last six months. A recall names specific lots from one company, so check the lot number on your own bottle rather than assuming every product is affected; your pharmacist can check whether your supply came from an affected lot.
