Edema associated with congestive heart failure (CHF), liver cirrhosis, and renal disease, including nephrotic syndrome 20-80 mg PO once daily; may be increased by 20-40 mg q6-8hr; not to exceed 600 mg/day Alternative: 20-40 mg IV/IM once; may be increased by 20 mg q2hr; individual dose not to exceed 200 mg/dose Refractory CHF may necessitate larger doses Excessive diuresis may cause dehydration and electrolyte loss in elderly; lower initial dosages and more gradual adjustments are recommended (eg, 10 mg/day PO)Increase in blood urea nitrogen (BUN) and loss of sodium may cause confusion in elderly; monitor renal function and electrolytes Anaphylaxis Anemia Anorexia Diarrhea Dizziness Glucose intolerance Glycosuria Headache Hearing impairment Hyperuricemia Hypocalcemia Hypokalemia Hypomagnesemia Hypotension Increased patent ductus arteriosus during neonatal period Muscle cramps Nausea Photosensitivity Rash Restlessness Tinnitus Urinary frequency Urticaria Vertigo Weakness Toxic epidermal necrolysis, Stevens-Johnson Syndrome, erythema multiforme, drug rash with eosinophila and systemic symptoms, acute generalized exanthematous pustulosis, exfoliative dermatitis, bullous pemphigoid purpura, pruritus Agent is potent diuretic that, if given in excessive amounts, may lead to profound diuresis with water and electrolyte depletion Careful medical supervision is required; dosing must be adjusted to patient's needs Use caution in systemic lupus erythematosus, liver disease, renal impairment Concomitant ethacrynic acid therapy (increases risk of ototoxicity) Risks of fluid or electrolyte imbalance (including causing hyperglycemia, hyperuricemia, gout), hypotension, metabolic alkalosis, severe hyponatremia, severe hypokalemia, hepatic coma and precoma, hypovolemia (with or without hypotension) Do not commence therapy in hepatic coma and in electrolyte depletion until improvement is noted IV route twice as potent as PO Food delays absorption but not diuretic response May exacerbate lupus Possibility of skin sensitivity to sunlight Prolonged use in premature neonates may cause nephrocalcinosis Efficacy is diminished and risk of ototoxicity increased in patients with hypoproteinemia (associated with nephrotic syndrome); ototoxicity is associated with rapid injection, severe renal impairment, use of higher than recommended doses, concomitant therapy with aminoglycoside antibiotics, ethacrynic acid, or other ototoxic drugs To prevent oliguria, reversible increases in BUN and creatinine, and azotemia, monitor fluid status and renal function; discontinue therapy if azotemia and oliguria occur during treatment of severe progressive renal disease FDA-approved product labeling for many medications have included a broad contraindication in patients with a prior allregic reaction to sulfonamides; however, recent studies have suggested that crossreactivity between antibiotic sulfonamides and nonantibiotic sulfonamides is unlikely to occur In cirrhosis, electrolyte and acid/base imbalances may lead to hepatic encephalopathy; prior to initiation of therapy, correct electrolyte and acid/base imbalances, when hepatic coma is present High doses ( 80 mg) of furosemide may inhibit binding of thyroid hormones to carrier proteins and result in transient increase in free thyroid hormones, followed by overall decrease in total thyroid hormone levels In patients at high risk for radiocontrast nephropathy furosemide can lead to higher incidence of deterioration in renal function after receiving radiocontrast compared to high-risk patients who received only intravenous hydration prior to receiving radiocontrast Observe patients regularly for possible occurrence of blood dyscrasias, liver or kidney damage, or other idiosyncratic reactions Cases of tinnitus and reversible or irreversible hearing impairment and deafness reported Hearing loss in neonates has been associated with use of furosemide injection; in premature neonates with respiratory distress syndrome, diuretic treatment with furosemide in the first few weeks of life may increase risk of persistent patent ductus arteriosus (PDA), possibly through a prostaglandin-E-mediated process Excessive diuresis may cause dehydration and blood volume reduction with circulatory collapse and possibly vascular thrombosis and embolism, particularly in elderly patients Increases in blood glucose and alterations in glucose tolerance tests (with abnormalities of fasting and 2 hour postprandial sugar) have been observed, and rarely, precipitation of diabetes mellitus reported 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 initial stages of treatment Hypokalemia may develop with furosemide, especially with brisk diuresis, inadequate oral electrolyte intake, when cirrhosis is present, or during concomitant use of corticosteroids, ACTH, licorice in large amounts, or prolonged use of laxatives Pregnancy category: C;

Heart : Increase in cholesterol and low blood pressure. Description Furosemide belongs to a class of drugs known as diuretics, or "water pills." Lasix happens to be a strong diuretic, and is indicated to treat excess fluid and swelling in the body caused by conditions such as heart failure, kidney failure, and cirrhosis (a liver disease). Side effects associated with this drug include low blood pressure, and water and electrolyte depletion. According to physicians, caution is advised in prescribing this drug to people with kidney dysfunction, and, monitoring will be important. Further, since Lasix tends to drain potassium from the body, your doctor may advise a diet rich in potassium from sources such as bananas and oranges or may prescribe potassium supplements. Newly discovered uses (off-label) You can order Furosemide to treat acute asthma, allergen-induced asthma, ascites in cirrhosis, aspirin-sensitive asthma, bronchopulmonary dysplasia (in infants), chronic asthma, membranous nephropathy, nocturia. It can be used for prevention of exercise-induced bronchospasm and steroid-dependent asthmas. Potential side effects Lowered blood pressure upon standing (orthostatic hypotension), dehydration, numbness, dizziness, lightheadedness, various skin rashes, skin reactions related to sun exposure (photosensitivity), increased levels of glucose or uric acid, decreased levels of potassium or chloride, nausea, vomiting, anorexia, gastric irritation, urinary bladder spasm, weakness, hearing impairment, ringing in the ears, decrease in kidney function.
