Initially, rapid administration of iv furosemide lasix, 20 to 80 mg PO as a single dose; may repeat rapid administration of iv furosemide lasix in 6 to 8 hours.

Titrate upward in 20 to 40 mg increments. Heart failure guidelines recommend adding a loop diuretic to standard therapy for reduced ejection fraction heart failure HFrEF patients with volume overload. Diuretics should also be used in preserved ejection fraction heart failure HFpEF. Adjust to minimum effective dose for maintenance ; large doses are not recommended for chronic use. Because of the risk for accumulation, chronic doses should not be administered more frequently than every 24 hours.

Initially, 20 to 40 mg IV or IM, increasing by 20 mg every 2 hours as needed to attain clinical response. Administer IV doses slowly. Use the lowest effective dose. Because of the risk for accumulation, doses should not be administered more frequently than every 24 hours. Specific dosing information for adolescents is not available; however, a bolus dose of 0. A loading dose of 0. The infusion was doubled every 2 hours to a maximum of 0. Compared example advertising plan patients receiving intermittent IV doses, patients receiving continuous infusions had a greater urine output per dose of drug, less variability in urine output, and lower urinary losses of sodium and chloride.

Initially, 40 mg IV injected slowly; then 80 mg IV injected slowly in 2 hours if needed. The authors reported an increase in PCWP in all control groups after the transfusions. Although use in clinical practice is not uncommon, limited published data are available evaluating furosemide prior to or after the administration of blood products.

The infants were 6. The infants that received furosemide demonstrated an improvement in lung compliance, tidal volume, and minute ventilation compared to baseline. There was no observed improvement in these values in the untreated group. The authors noted no difference in the clinical respiratory status between the 2 groups. Some authors caution against the routine use of furosemide following PRBC transfusions due to a lack of efficacy data and the potential for electrolyte imbalance.

For immediate diuresis, to mg once daily has been suggested. Adjust to minimum effective dose for maintenance; large doses are not recommended for chronic use.

Initially, to mg IV. Traditionally, it has been recommended that doses can be doubled every 2 to 24 hours until desired clinical response, however, most clinicians would probably consider to mg a maximum dose and either administer a different loop-active agent, or add a second agent in combination with furosemide.

Initially, 40 mg PO twice daily. Adjust dose according to response. Alternatively, 10 to 20 mg twice daily adjusting the dose according to clinical response. The American Academy of Pediatrics states that furosemide may be useful as adjunctive therapy in patients with resistant hypertension, especially if concomitant renal disease is present.

Geriatric patients may be more sensitive to the effects of the usual adult dose. Initially, 80 mg IV or IM; repeat the dose every 12 hours as needed based on clinical response. Less severe cases may use smaller doses every 24 hours. Initiate saline administration before the first dose of furosemide to avoid volume contraction which may limit the desired calciuric response. Initially, rapid administration of iv furosemide lasix mg IV or IM.

The dose may be repeated every 4 hours as needed based on clinical response. Initially, 40 mg PO once daily, rapid administration of iv furosemide lasix, in the morning in combination with spironolactone; dose may be increased after 23 days if no clinical response.

Premature and Term Neonates older than 32 weeks postconceptional age: Premature Neonates 32 weeks postconceptional age and younger: No specific dosage adjustment is needed; see the dosage for rapid administration of iv furosemide lasix treatment of ascites.

Diuretics should be used with caution in patients with hepatic disease since minor alterations of fluid and electrolyte balance may precipitate hepatic coma. No specific dosage adjustments are recommended. Higher doses with extended dosage intervals may be effective in patients with end-stage renal disease ESRD. In patients with acute or chronic renal failure, larger doses of oral or IV furosemide have been used.

The half-life of furosemide in neonates will be prolonged. Increasing rapid administration of iv furosemide lasix dosage interval is suggested to help prevent toxicity. Elderly patients may be more sensitive to the effects of normal adult doses. Do not squirt onto the back of the throat because this may cause gagging. Rinse the dropper or syringe in warm water after each use. Visually inspect parenteral products for particulate matter and discoloration prior to administration whenever solution and container permit.

Inject each 20 mg of furosemide slowly IV rapid administration of iv furosemide lasix 12 minutes. Inject furosemide deeply into a large muscle.

Aspirate prior to injection to avoid injection into a blood vessel. Do not store for later use. Furosemide is contraindicated in patients with known hypersensitivity to this drug. Because cross-sensitivity with furosemide has rarely been observed, bumetanide can be substituted for furosemide in patients allergic to furosemide, rapid administration of iv furosemide lasix.

The risk of an allergic reaction after administration of a loop diuretic in a patient with sulfonamide hypersensitivity or thiazide diuretic hypersensitivity appears to be very low. Although furosemide is a sulfonamide derivative, sulfonamide cross-sensitivity has been rarely documented, rapid administration of iv furosemide lasix. A case report, published indocuments an anaphylactic reaction to IV furosemide in a patient who was subsequently skin-tested with furosemide, bumetanide, ethacrynic acid, chlorothiazide, and sulfamethoxazole-trimethoprim.

A positive reaction was elicited to all except ethacrynic acid. This case documents hypersensitivity to both furosemide and bumetanide in a patient with sulfonamide hypersensitivity.

Prior to this, neither the FDA nor the manufacturer of furosemide Lasix had received any reports of cross-sensitivity between furosemide and sulfonamide antibiotics. Furosemide does not contain the N4-aromatic amine or the N1-substituent which are present in sulfonamide antibiotics. Non-arylamine sulfonamide derivatives, such as loop diuretics, have been proposed to have a lower risk of allergic reactions in patients with sulfonamide allergy, presumably due to lack of an arylamine group at the N4 position a proposed structural site of action for sulfonamide allergy.

One large retrospective cohort study has reported that in patients with the presence of an allergic reaction after exposure to a sulfonamide antibiotic, 9. A causal relationship between sulfonamide hypersensitivity and allergic reactions with non-arylamine sulfonamide derivatives has not been definitively established and remains controversial. In general, patients with a documented sulfonamide allergy are considered to be predisposed for development of allergic drug reactions.

Preexisting electrolyte imbalance such as severe hyponatremia, hypokalemia, hypocalcemia, hypochloremia, or hypomagnesemia should be corrected before initiating furosemide therapy. Blood and urine glucose levels should be assessed in patients with diabetes mellitus or hyperglycemia during treatment with furosemide; loop diuretics can impair glucose tolerance.

Patients with ventricular arrhythmias, heart failure, rapid administration of iv furosemide lasix, potassium-losing nephropathy, aldosterone excess, or diarrhea rapid administration of iv furosemide lasix be monitored closely since furosemide-induced hypokalemia can exacerbate these conditions.

Excessive diuresis with furosemide should be avoided in patients with acute myocardial infarction due to the risk of precipitating shock. Furosemide is contraindicated in patients with anuria.

It should be used cautiously in any patient with renal disease such as severe renal impairment or renal failure. Drug-induced hypovolemia can precipitate azotemia in these patients. The presence of hypoproteinemia e. The risk of ototoxicity may also be increased when furosemide is administered to patients with severe renal impairment. Furosemide is an effective diuretic for many patients with renal impairment. Renal impairment may reduce clearance and warrant the use of higher doses with extended dosing intervals.

Furosemide may be less effective in these patients and delayed excretion of drug may increase the risk of toxicity. Patients with pre-existing hypovolemia or hypotension should have their condition corrected before furosemide is initiated. Orthostatic hypotension may occur during treatment with loop diuretics. Excessive hypotension can result in syncope. The antihypertensive effects of diuretics may be enhanced in patients predisposed for orthostatic hypotension, including the post-sympathectomy patient, rapid administration of iv furosemide lasix.

Furosemide has been reported to activate or exacerbate systemic lupus erythematosus SLEalthough the association is less certain than with procainamide or other drugs.

Since furosemide can reduce the clearance of uric acid, patients with gout or hyperuricemia can have exacerbations of their disease. High doses and accumulation of furosemide may cause ototoxicity. Use furosemide with caution in patients with hearing impairment. Do not exceed the recommended rate of infusion when IV doses are administered. Furosemide has been reported to cause pancreatitis.

It should be used with caution in patients with a history of pancreatitis. Do not use furosemide during pregnancy unless the potential benefit justifies the potential risk to the fetus. Because of the risk for higher birth weights, monitor fetal growth with furosemide therapy during pregnancy. There are no well-controlled studies of furosemide in pregnant women. Furosemide has been shown to cause unexplained maternal deaths and abortions in rabbits at 2, 4, and 8 times the maximum recommended human dose.

Use caution when administering furosemide to a breast-feeding mother. Furosemide is excreted in human breast milk. In addition, furosemide may suppress lactation as a result of intense diuresis.
