Warnings for people with certain health conditions
For people living with kidney problems: Furosemide is removed from your body by your kidneys.
If you have kidney problems, more of the drug may stay in your body longer. This could lead to dangerous side effects, including very low blood pressure. Your doctor may start you on a lower dose of this drug. Your doctor may also monitor how well your kidneys are working to make sure furosemide is safe for you to take.
For people living with liver problems: If you have liver problems such as cirrhosis or ascites, it’s best to receive furosemide in the hospital. Furosemide can cause very low electrolyte levels, which can cause serious liver damage and loss of brain function. (Electrolytes are minerals that help control the fluid balance in your body and help with other important functions.) Your doctor will monitor you closely.
For people living with diabetes: Furosemide can make it harder to control your blood sugar (glucose) levels. Before taking this drug, be sure your doctor knows you have diabetes.
For people living with bladder disorders: If you have severe problems with emptying your bladder completely, furosemide can make your condition worse.
Before taking this drug, be sure your doctor knows you have a bladder disorder.
For people living with thyroid problems: High doses (over 80 mg) of furosemide can cause low levels of thyroid hormones. Be sure to tell your doctor about your thyroid problems before you start taking furosemide.
Warnings for other groups
For pregnant people: Talk with your doctor if you’re pregnant or planning to become pregnant. Research in animals has shown adverse effects on the fetus when the mother takes the drug. There haven’t been enough studies done on humans to be certain how the drug might affect the fetus. This drug should only be used if the potential benefit justifies the potential risk to the fetus.
For people who are nursing: Furosemide may pass into breast milk and can cause serious side effects in a child who is breastfed. It may also cause your body to produce less milk. Tell your doctor if you are nursing.
You will need to decide either to stop nursing or stop taking this drug.

Pharmacotherapeutic group
ATX code: C03CA01.
Pharmacodynamics
Inhibits the reabsorption of sodium and chloride ions, mainly in the thick segment of the ascending part of the loop of Henle. Furosemide has a pronounced diuretic, natriuretic, chloruretic effect. In addition, it increases the excretion of potassium, calcium, magnesium ions.
In heart failure, after 20 minutes it leads to a decrease in the preload on the heart. The maximum hemodynamic effect is achieved by the second hour of the drug’s action, which is due to a decrease in the tone of the venous vessels, a decrease in the volume of circulating blood and interstitial fluid. It has a hypotensive effect due to an increase in the excretion of sodium chloride, a decrease in the response of vascular smooth muscles to vasoconstrictor effects and as a result of a decrease in the volume of circulating blood.
Pharmacokinetics
Bioavailability 60-70%. The relative volume of distribution is 0.2 l / kg. Communication with blood plasma proteins – 98%. Penetrates through the placental barrier, excreted in breast milk. Metabolized in the liver. It is secreted into the lumen of the renal tubules through the anion transport system existing in the proximal nephron.
60-70% is excreted by the kidneys, the rest – by the intestines. The half-life is 1-1.5 hours. Indications for use
Edema of hepatic origin, usually in combination with potassium-sparing diuretics. Arterial hypertension in patients with chronic renal failure who are contraindicated in the appointment of thiazide diuretics (especially with creatinine clearance below 30 ml / min). Dosage and administration
The dose depends on the course and severity of the disease.
Adults. With edema of cardiac, renal or hepatic origin:
– moderate condition: ½-1 tablet per day,
– severe condition: 2-3 tablets per day in 1 or 2 doses, or 3-4 tablets per day in 2 doses.
For high blood pressure in patients with chronic renal failure: in combination with other antihypertensive agents (antagonists of the renin-angiotensin system), the usual doses of 20-120 mg per day in one or two doses are recommended.
Children
For the treatment of edema, the daily dose is 1–2 mg/kg of body weight in 1–2 divided doses.
Use in elderly patients
Dose selection and adjustment in elderly patients should be done with caution, usually starting at the lower end of the therapeutic dose range. Use during pregnancy and lactation
Excreted in milk in women during lactation, in connection with which it is necessary to stop breastfeeding for the period of treatment.
Precautions
In hepatocellular insufficiency, treatment should be carried out with caution, under strict control of electrolytes, given the risk of hepatic encephalopathy. If necessary, treatment should be stopped immediately.
Taking furosemide in case of partial obstruction of the urinary tract can lead to urinary retention. Diuresis should be closely monitored, especially at the start of treatment with furosemide.
Patients with hypersensitivity to sulfonamides and sulfonylurea derivatives may have cross-sensitization to furosemide.
Photosensitivity reactions have been reported with thiazide diuretics. If photosensitivity reactions occur, furosemide should be discontinued. If necessary, it is recommended to protect exposed areas of the skin exposed to sunlight or ultraviolet radiation from artificial sources.
Since the medicinal product contains lactose, its use is not recommended in patients with galactose intolerance, lactase deficiency or glucose-galactose malabsorption syndrome.
Electrolyte balance
Natremia. It is necessary to control the level of sodium before starting therapy and regularly monitor it thereafter. Treatment with diuretics can provoke hyponatremia. A decrease in the level of sodium in the blood is initially asymptomatic, regular monitoring should be more frequent in patients at risk: advanced age, cachexia (malnutrition) or cirrhosis.
Potassium. When using loop diuretics, a decrease in sodium levels with hypokalemia is possible. The risk of sudden hypokalemia (Glycemia. The frequency of glycemia is low, however, in diabetes mellitus, it is necessary to systematically monitor the level of glucose in the blood and urine.
Uricemia. The release of uric acid decreases, therefore, with hyperuricemia and especially gout, the use is not recommended.
Careful monitoring of patients at high risk of developing electrolyte disorders (vomiting, diarrhea, profuse sweating) is necessary. Dehydration, hypovolemia or acid-base imbalance requires adjustment of therapy and / or temporary discontinuation of treatment.
Creatinine. Regular monitoring of serum creatinine is recommended during treatment with furosemide.
Careful monitoring of patients at high risk of developing electrolyte disorders (vomiting, diarrhea, sweating) is necessary. Dehydration, hypovolemia, or acid-base imbalance require treatment adjustment and/or temporary discontinuation of treatment.
Athletes.
The presence of furosemide results in positive tests in anti-doping controls.
Against the background of course treatment, it is necessary to periodically monitor blood pressure, the content of electrolytes in blood plasma (including Na +, Ca2 +, K +, Mg2 +), acid-base state, the content of residual nitrogen, creatinine, uric acid, liver function and, if necessary, carry out an appropriate correction of treatment.
Patients with hypersensitivity to sulfonamides and sulfonylurea derivatives may have cross-sensitization to furosemide.
When prescribing high doses of furosemide, in order to avoid the development of hyponatremia and metabolic alkalosis, it is not advisable to limit the intake of table salt.
For the prevention of hypokalemia, the simultaneous administration of potassium supplements or potassium-sparing diuretics (spironolactone), as well as a diet rich in potassium, is recommended.
Selection of the dosage regimen for patients with ascites on the background of cirrhosis of the liver, liver failure should be carried out in stationary conditions (disturbances in water and electrolyte balance can cause the development of hepatic coma). Regular monitoring of the content of plasma electrolytes is shown.
With the appearance or increase of azotemia and oliguria in patients with severe progressive kidney disease, it is recommended to suspend treatment.
In patients with diabetes mellitus or with impaired glucose tolerance, periodic monitoring of blood and urine glucose levels is required.
In patients who are unconscious, with benign prostatic hyperplasia, narrowing of the ureters or hydronephrosis, control of urination is necessary (acute urinary retention is possible).
Due to the presence of lactose in the composition, this drug is contraindicated in case of congenital galactosemia, glucose-galactose malabsorption syndrome, lactase deficiency. Interactions with other drugs
Co-administration of furosemide and chloral hydrate is not recommended.
The ototoxicity of aminoglycosides and other ototoxic drugs may be increased by concomitant use of furosemide. Such combinations should be avoided, as the resulting hearing loss may be irreversible. An exception is the use of this combination for health reasons.
Concomitant use of furosemide and lithium preparations is not recommended.
Combinations requiring special precautions
If forced diuresis with furosemide is required during treatment with cisplatin, furosemide may be given at low doses (up to 40 mg) in normal renal function and no fluid deficit. Otherwise, it is possible to increase the nephrotoxic effect of cisplatin.
Treatment with furosemide can lead to severe hypotension and deterioration of renal function, and in some cases to the development of acute renal failure, especially when prescribing angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor antagonists (sartans) at the first dose or increased doses. It is necessary to cancel furosemide, or reduce its dose 3 days before the use of ACE inhibitors or sartans.
Furosemide should be used with caution in combination with risperidone, as mortality may be increased in elderly patients. The need for joint use must be justified taking into account the risk and benefits of this combination. The risk of mortality increases in the presence of dehydration.
Significant interactions of furosemide and other medicinal products
Co-administration of non-steroidal anti-inflammatory drugs (NSAIDs), including acetylsalicylic acid, may reduce the effect of furosemide. In patients with dehydration or hypovolemia, NSAIDs can cause acute renal failure.
The toxic effect of salicylates may increase.
Furosemide may be less effective when phenytoin is given concomitantly.
With the simultaneous use of glucocorticosteroids, carbenoxolone, licorice in large quantities, and prolonged use of laxatives, hypokalemia may increase. Hypokalemia or hypomagnesemia may increase myocardial sensitivity to cardiac glycosides and drugs that prolong the QT interval.
The effect of drugs that lower blood pressure (antihypertensive, diuretic and other drugs) can be enhanced when used simultaneously with furosemide. Simultaneous use of probenecid, methotrexate and other drugs that are excreted by tubular secretion may reduce the effectiveness of furosemide. Furosemide can lead to a decrease in the excretion of these drugs. It is possible to increase their levels in the blood serum and increase the risk of side effects.
The effectiveness of hypoglycemic agents and vasoconstrictive amines (epinephrine / adrenaline, norepinephrine / norepinephrine) may be weakened, and theophylline and curare-like agents – enhanced.
Furosemide may increase the damaging effect on the kidneys of nephrotoxic drugs. In patients receiving concomitant treatment with furosemide and individual cephalosporins in high doses, deterioration in renal function is possible.
Co-administration of ciclosporin A and furosemide may increase the risk of developing secondary gouty arthritis due to furosemide-induced hyperuricemia and deterioration of urate excretion by the kidneys caused by ciclosporin.
Patients with a high risk of developing nephropathy, when using furosemide in conjunction with radiopaque agents, are more susceptible to impaired renal function.
When used in conjunction with thiazides, photosensitivity reactions may develop. In the event of an unexpected photosensitivity reaction when taking furosemide, it is recommended to stop therapy. If repeated administration is necessary, ultraviolet radiation or solar insolation should be avoided. Contraindications
