4. Clinical particulars
4.1 Therapeutic indications

Furosemide 10 mg/ml solution for injection/infusion is indicated when no adequate diuresis is achieved with oral administration of furosemide or when oral use is not possible:

‒ oedemas and/or ascites secondary to cardiac or hepatic disorders

‒ oedemas secondary to renal disorders

‒ pulmonary oedema (e.g. in acute heart failure)

‒ hypertensive crisis (in addition to other therapeutic measures)

4.2 Posology and method of administration

The dosage should be individually established, mainly depending on the success of therapy. The lowest dose at which the desired effect is obtained should always be used.



Oedemas and/or ascites secondary to cardiac or hepatic disorders

Initial dose 2-4 ml (equivalent to 20-40 mg furosemide) IV. For oedemas that are difficult to mobilise, this dose can be repeated at appropriate intervals until the onset of diuresis.

Oedemas secondary to renal disorders

Initial dose 2-4 ml (equivalent to 20-40 mg furosemide) IV. For oedemas that are difficult to mobilise, this dose can be repeated at appropriate intervals until the onset of diuresis.

In nephrotic syndrome, the dose must be cautiously determined due to the risk of an increase in adverse reactions.

Pulmonary oedema (e.g. in acute heart failure)

Use in conjunction with other therapeutic measures. Initial dose 2-4 ml (equivalent to 20-40 mg furosemide) IV.

If there is still no increase in diuresis, repeat after 30-60 minutes, if necessary at twice the dose.

Hypertensive crisis

The dose is 2-4 ml (equivalent to 20-40 mg furosemide) in addition to other therapeutic measures.

In adults, the maximum daily dose of furosemide should not exceed 1500 mg.

Paediatric population

Infants and children under 15 years should be given furosemide via the parenteral route only as an exception in threatening situations. The mean daily dose is 0.5 mg furosemide/kg body weight. Exceptionally, up to 1 mg furosemide/kg body weight can be injected IV.


The recommended initial dose is 20 mg daily, increasing gradually until the required response is achieved.

Renal impairment

In patients with advanced renal failure (serum creatinine > 442 micromol/l [> 5 mg/dl]), the injection/infusion rate should not exceed 0.25 ml solution per minute (equivalent to 2.5 mg furosemide per minute).

Method of administration

Intravenous or intramuscular.

As a rule, Furosemide 10 mg/ml solution for injection/infusion is administered intravenously. In exceptional cases where neither oral nor intravenous administration is possible, Furosemide 10 mg/ml solution for injection/infusion can be administered intramuscularly, but not in acute situations (e.g. not in pulmonary oedema) and not at higher doses.

Parenteral administration of furosemide is indicated only in cases where oral administration is not feasible or not efficient (e.g. in patients with poor intestinal absorption) or when a quick effect is required.

In order to achieve optimum efficacy and suppress counter-regulation, a continuous furosemide infusion should be preferred to the repeated injections.

Parenteral use of furosemide, as soon as treatment permits, should be switched to oral administration.

With intravenous use, furosemide should be injected slowly. The injection rate of 0.4 ml solution for injection (equivalent to 4 mg furosemide) per minute must not be exceeded.

In cases where a dose increase to 25 ml is required (equivalent to 250 mg furosemide), this dose should be administered via a syringe pump. If necessary, the solution can be diluted (see section 6.6).

Furosemide 10 mg/ml solution for injection/infusion must not be given with other medicinal products in a mixed syringe.

Care must be taken to ensure that the pH of in-use solution is in the weakly alkaline to neutral range (pH not lower than 7). Acid solutions must not be used, as the active substance may precipitate.

Duration of use

The duration of use depends on the nature and severity of the disease.

4.3 Contraindications

‒ Hypersensitivity to furosemide, sulfonamides (possible cross-allergy with furosemide) or to any of the excipients listed in section 6.1.

‒ Renal failure with anuria not responding to furosemide therapy.

‒ Renal failure as a result of poisoning by nephrotoxic or hepatotoxic agents.

‒ Renal failure associated with hepatic coma.

‒ Coma and hepatic precoma associated with hepatic encephalopathy.

‒ Severe hypokalaemia (see section 4.8).

‒ Severe hyponatraemia.

‒ Hypovolaemia or dehydration.

‒ Breast-feeding.

4.4 Special warnings and precautions for use

Particularly careful monitoring is required in the following cases:

‒ hypotension;

‒ manifest or latent diabetes mellitus (regular glycaemic monitoring necessary);

‒ gout (regular monitoring of serum uric acid);

‒ urinary obstruction (e.g. in prostatic hypertrophy, hydronephrosis, ureteric stenosis);

‒ hypoproteinaemia, e.g. in nephrotic syndrome (careful titration of the dosage);

‒ hepatorenal syndrome (rapidly progressing renal failure combined with severe hepatic disease, e.g. liver cirrhosis);

‒ patients who would be at particular risk from an unwanted severe hypotensive episode, e.g. patients with cerebrovascular ischaemia or coronary heart disease;

‒ preterm infants (risk of developing nephrocalcinosis/nephrolithiasis; monitoring of renal function, renal ultrasound).

In preterm infants with respiratory distress syndrome, diuretic treatment with furosemide in the first weeks of life can increase the risk of patent ductus arteriosus.

Patients receiving treatment with furosemide may experience symptomatic hypotension with dizziness, fainting or loss of consciousness. This particularly applies to the elderly, patients concomitantly taking other medicinal products that can cause hypotension and patients with other disorders associated with a risk of hypotension.

In patients with micturition disorders (e.g. in prostatic hypertrophy), furosemide may only be used if free urinary flow is ensured, as any sudden diuresis can lead to urinary retention with overextension of the bladder.

Furosemide leads to increased excretion of sodium and chloride and, consequently, of water. Excretion of other electrolytes (particularly potassium, calcium and magnesium) is also increased. As disturbances in the fluid and electrolyte balance are frequently observed during therapy with Furosemide 10 mg/ml solution for injection/infusion as a result of increased electrolyte excretion, regular monitoring of serum electrolytes is indicated.

Especially during long-term therapy with Furosemide 10 mg/ml solution for injection/infusion, serum electrolytes (especially potassium, sodium, calcium), bicarbonate, creatinine, urea and uric acid, as well as blood sugar, should be regularly monitored.

Particularly close supervision is required in patients at high risk of developing electrolyte disturbances or in the event of more severe fluid loss (e.g. due to vomiting, diarrhoea or intensive sweating). Hypovolaemia or dehydration, as well as marked electrolyte disturbances or acid-base imbalances, must be corrected. This may necessitate temporary discontinuation of treatment with furosemide.

The possible development of electrolyte disturbances is influenced by underlying diseases (e.g. liver cirrhosis, heart failure), co-medication (see section 4.5) and diet.

The weight loss caused by increased urine excretion should not exceed 1 kg/day, irrespective of the degree of urine excretion.

In nephrotic syndrome, the dose must be cautiously determined due to the risk of an increase in adverse reactions.

Concomitant use with risperidone:

In placebo-controlled studies with risperidone in elderly patients with dementia, a higher incidence of mortality was observed in patients treated concomitantly with furosemide and risperidone (7.3%; mean age 89 years, age range 75 to 97 years) compared to patients who had received risperidone alone (3.1%; mean age 84 years, age range 70 to 96 years) or furosemide alone (4.1%; mean age 80 years, age range 67 to 90 years). Concomitant use of risperidone with other diuretics (mainly low-dose thiazide diuretics) was not associated with any similar findings.

No pathophysiological mechanism could be identified to explain this finding, and no consistent pattern for cause of death was established. Nevertheless, caution is indicated and the risks and benefits of this combination or co-treatment with other potent diuretics should be considered prior to the decision to use. There was no increased incidence of mortality in patients who had received other diuretics as concomitant treatment with risperidone. Regardless of treatment, dehydration was an overall risk factor for mortality and should therefore be avoided in elderly patients with dementia (see section 4.3).

There is a potential for exacerbation or activation of systemic lupus erythematosus.

The use of Furosemide 10 mg/ml solution for injection/infusion can lead to positiveresults in doping controls. In addition, abuse of Furosemide 10 mg/ml solution forinjection/infusion as a doping agent can endanger health.


This medicinal product contains 3.686 mg sodium per ml of solution, equivalent to 0.18 % of the WHO recommended maximum daily intake of 2 g sodium for an adult.

4.5 Interaction with other medicinal products and other forms of interaction

Glucocorticoids, carbenoxolone, laxatives and liquorice

Concomitant use of furosemide and glucocorticoids, carbenoxolone or laxatives can lead to increased potassium losses with a risk for the development of hypokalaemia. In this respect, large amounts of liquorice act like carbenoxolone.

Non-steroidal anti-inflammatory drugs (NSAIDs) and high-dose salicylates

NSAIDs (e.g. indomethacin and acetylsalicylic acid) can attenuate the effect of furosemide. In patients developing hypovolaemia during furosemide therapy or presenting with dehydration, concomitant administration of NSAIDs can precipitate acute renal failure.

The toxicity of high-dose salicylates can be potentiated with concomitant use of furosemide.

Medicinal products that undergo considerable renal tubular secretion

Probenecid, methotrexate and other medicinal products that, like furosemide, undergo considerable renal tubular secretion can reduce the effect of furosemide.

Conversely, furosemide can reduce the renal elimination of probenecid, methotrexate. In high-dose treatment (especially if both the dose of furosemide and the other medicinal product are high), this can lead to elevated serum levels and a greater risk of adverse effects due to furosemide or the concomitant medication.


Attenuation of the effect of furosemide has been described with concomitant administration of phenytoin.

Cardiac glycosides and medicinal products that may cause prolongation of the QT interval

In concomitant treatment with cardiac glycosides, it should be remembered that, if hypokalaemia and/or hypomagnesaemia develop during furosemide therapy, myocardial sensitivity to cardiac glycosides will be increased.

There is a greater risk of ventricular arrhythmias (including torsade de pointes) with concomitant use of medicinal products that can cause long QT interval syndrome (e.g. terfenadine, some class I and III antiarrhythmic agents) and in the presence of electrolyte disturbances.

Nephrotoxic medicinal products

Furosemide can potentiate the harmful effects of nephrotoxic medicinal products (e.g. antibiotics such as aminoglycosides, cephalosporins, polymyxins).

Renal function may deteriorate in patients treated concomitantly with furosemide and high doses of certain cephalosporins.

If forced diuresis with furosemide is pursued during cisplatin treatment, furosemide may only be administered at low doses (e.g. 40 mg in patients with normal renal function) and if the fluid balance is positive. Otherwise, the nephrotoxicity of cisplatin may be enhanced.

Ototoxic medicinal products

The ototoxicity of aminoglycosides (e.g. kanamycin, gentamicin, tobramycin) and other ototoxic medicinal products may be increased with co-administration of furosemide. Any hearing disorders that occur may be irreversible. Concomitant use of the above-mentioned medicinal products should therefore be avoided.

The possibility of hearing damage must be taken into account with concomitant use of cisplatin and furosemide.


Concomitant administration of furosemide and lithium leads to potentiation of the cardio- and neurotoxic effects of lithium, due to reduced lithium excretion. Therefore, careful monitoring of the lithium plasma level is recommended in patients receiving this combination.

Other antihypertensive medicinal products

If other antihypertensive agents, diuretics or medicinal products with a hypotensive potential are co-administered with furosemide, a relatively sharp decrease in blood pressure can be expected.

ACE inhibitors or angiotensin II receptor antagonists

Severe hypotensive episodes or even shock and worsening renal function (acute renal failure in individual cases) have been observed, particularly when an ACE inhibitor or angiotensin II receptor antagonist has been given for the first time, or for the first time at a higher dose. If possible, furosemide therapy should therefore be temporarily discontinued or, as a minimum, the dose should be reduced for 3 days before therapy with an ACE inhibitor or angiotensin II receptor antagonist is started or its dose increased.

Theophylline and curare-type muscle relaxants

The effect of theophylline or curare-type muscle relaxants may be potentiated by furosemide.

Antidiabetic medicinal products

The effect of antidiabetic agents may be attenuated with concomitant use of furosemide.


The effect hypertensive sympathomimetics (e.g. epinephrine, norepinephrine) may be attenuated with concomitant use of furosemide.


Caution is indicated in patients treated with risperidone and the risks and benefits of such combination or co-treatment with furosemide or with other potent diuretics should be weighed up before deciding to treat (see section 4.4 regarding increased mortality in elderly patients with dementia concomitantly receiving risperidone).


High doses of furosemide may inhibit the binding of thyroid hormones to transport proteins. This may result in an initial transient increase in free thyroid hormones, followed overall by a decrease in total thyroid hormone levels. Thyroid hormone levels should be monitored.

Other interactions

Concomitant use of ciclosporin A and furosemide is associated with an increased risk of gouty arthritis as a result of hyperuricaemia caused by furosemide and impaired renal uric acid excretion caused by ciclosporin.

In patients at high risk of kidney damage due to radiocontrast media, worsening of renal function occurred more frequently with furosemide treatment after a radiocontrast examination than in risk patients who received only intravenous hydration prior to the contrast examination.

In isolated cases, after intravenous administration of furosemide, sensations of heat, sweating, restlessness, nausea, hypertension and tachycardia may occur within 24 hours after taking chloral hydrate. Concomitant use of furosemide and chloral hydrate should therefore be avoided.

4.6 Fertility, pregnancy and lactation


Furosemide should only be used in pregnancy for short periods and only after a particularly careful review of the indication for its use, as furosemide crosses the placental barrier.

Diuretics are not suitable for the routine treatment of hypertension and oedemas in pregnancy, as they impair placental perfusion and thus intrauterine growth.

If it is necessary to administer furosemide to pregnant women with heart failure or renal impairment, electrolytes and haematocrit, as well as foetal growth, must be closely monitored. Displacement of bilirubin from its albumin-binding sites and hence an increased risk of kernicterus in the presence of hyperbilirubinaemia has been discussed for furosemide.

Furosemide crosses the placenta and reaches 100% of maternal serum concentrations in umbilical cord blood. No malformations in humans have been reported to date, which might be associated with furosemide exposure. However, there is limited experience to allow a conclusive evaluation of any potential harmful effect on the embryo/foetus. Foetal urine production may be stimulated in utero. In the treatment of preterm infants with furosemide, urolithiasis has been observed to occur.


Furosemide is excreted in human milk and inhibits lactation. Women must therefore not be treated with furosemide if they are breast-feeding. If applicable, breast-feeding should be discontinued (see also section 4.3).


No data are available.

4.7 Effects on ability to drive and use machines

Even when used as directed, this medicinal product can affect responsiveness to such an extent that the ability to drive, use machines or perform hazardous tasks may be impaired. This particularly applies at the start of treatment, when increasing the dose or switching medicinal products and in association with alcohol.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the

Yellow Card Scheme, Website: or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose

a) Symptoms of overdose

The clinical picture in acute or chronic overdose depends on the extent of fluid and electrolyte loss. Overdose can lead to hypotension, orthostatic dysregulation, electrolyte disturbances (hypokalaemia, hyponatraemia, hypochloraemia) or alkalosis. In more severe cases of fluid depletion, marked hypovolaemia, dehydration, circulatory collapse and haemoconcentration with thrombotic tendency may occur. If fluid and electrolyte losses are rapid, delirious states may occur. In rare cases, anaphylactic shock (symptoms: sweating, nausea, cyanosis, severe hypotensive episode, impaired consciousness or even coma) may occur.

b) Therapeutic measures in case of overdose

In the event of overdose or signs of hypovolaemia (hypotension, orthostatic dysregulation), treatment with Furosemide 10 mg/ml solution for injection/infusion must be discontinued immediately.

In addition to monitoring vital parameters, the following must be repeatedly monitored and anomalies corrected as appropriate: fluid and electrolyte balance, acid-base balance, blood glucose and urinary substances.

In patients with micturition disorders (e.g. in patients with prostatic hypertrophy), free urinary flow must be ensured, as any sudden diuresis can lead to urinary retention with overextension of the bladder.

Treatment for hypovolaemia: volume replacement.

Treatment for hypokalaemia: potassium replacement.

Treatment for circulatory collapse: shock position, if necessary shock therapy.

Emergency measures for anaphylactic shock

At the first signs (e.g. cutaneous reactions such as urticaria or flushing, restlessness, headache, sweating, nausea, cyanosis):

‒ Stop the injection/infusion, maintain venous access.

‒ In addition to standard emergency procedures, Trendelenburg position, maintenance of airway patency, oxygen administration.

‒ If necessary, other measures must be implemented, including intensive care measures as appropriate (administration of epinephrine, volume replacements, glucocorticoids, etc.).

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: high-ceiling diuretics, sulfonamides, plain, ATC code: C03CA01

Furosemide is a potent, short- and fast-acting loop diuretic. By blocking the Na+/2Cl-/K+ ion carrier, it inhibits the reabsorption of these ions in the ascending limb of the loop of Henle. Thus, fractional sodium excretion can amount to as much as 35% of sodium filtered by the glomeruli. As a result of increased sodium excretion, there is increased urine excretion and a rise in K+ secretion in the distal tubules as a secondary effect of osmotically-bound water. The elimination of Ca2+ and Mg2+ ions is also increased. In addition to loss of the aforementioned electrolytes, there may be decreased uric acid excretion and disturbances of the acid-base balance tending towards metabolic alkalosis.

Furosemide interrupts the tubuloglomerular feedback mechanism at the macula densa and hence there is no attenuation of saluretic activity.

Furosemide leads to dose-dependent stimulation of the renin-angiotensin aldosterone system.

In heart failure, furosemide leads to an acute reduction in cardiac preload due to dilation of the venous capacitance vessels. This early vascular effect appears to be mediated by prostaglandins and is dependent on adequate renal function with activation of the renin-angiotensin-aldosterone system and intact prostaglandin synthesis.

The hypotensive effect of furosemide is the result of increased sodium chloride excretion and decreased responsiveness of the vascular smooth muscles to vasoconstrictive stimuli, as well as a reduction in blood volume.

5.2 Pharmacokinetic properties

After intravenous administration of furosemide, onset of action can be expected within 2 to 15 minutes.

Plasma protein binding of furosemide is approximately 95%; in renal impairment, it may be reduced by as much as 10%. The relative volume of distribution is 0.2 l/kg body weight (in neonates, 0.8 l/kg body weight).

Furosemide undergoes only minor hepatic metabolism (approximately 10%) and is mainly excreted in unchanged form. Elimination takes place via the kidneys (two-thirds) and the bile and faeces (one-third).

In patients with normal renal function, the elimination half-life is approximately 1 hour; it can be prolonged to as much as 24 hours in cases of terminal renal failure.

5.3 Preclinical safety data

Acute oral toxicity was low in all species tested. Chronic toxicity studies in rats and dogs led to changes in the kidneys (including fibrosis and calcification of the kidneys).

In vitro and in vivo genetic toxicology assays revealed no clinically relevant indications of any genotoxic potential for furosemide.

Long-term studies in rats and mice showed no indications of any tumorigenic potential.

In reproductive toxicology studies following administration of high doses, a reduced number of differentiated glomeruli and skeletal anomalies of the scapula, humerus and ribs (due to hypokalaemia) occurred in rat foetuses, as well as hydronephrosis in mouse and rabbit foetuses.
