Cautions
Use caution in systemic lupus erythematosus, liver disease, renal impairment
Concomitant ethacrynic acid therapy (increases risk of ototoxicity)
Furosemide may cause fluid, electrolyte, and metabolic abnormalities such as hypovolemia, hypokalemia, azotemia, hyponatremia, hypochloremic alkalosis, hypomagnesemia, hypocalcemia, hyperglycemia, or hyperuricemia, particularly in patients receiving higher doses, patients with inadequate oral electrolyte intake, and in elderly patients; serum electrolytes, CO2, BUN, creatinine, glucose, and uric acid should be monitored frequently during furosemide therapy
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; renal function must be monitored and renal ultrasonography performed in this age group
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; if physician elects to use high-dose parenteral therapy, controlled intravenous infusion is advisable (for adults, an infusion rate not exceeding 4 mg furosemide per minute has been used)
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 & Lactation
Pregnancy
Available data from published observational studies, case reports, and postmarketing reports, from decades of use, have not demonstrated a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes with furosemide use during pregnancy
Untreated congestive heart failure and cirrhosis of the liver can lead to adverse outcomes for the mother and fetus
Pregnant women with congestive heart failure are at increased risk for pre-term birth; stroke volume and heart rate increase during pregnancy, increasing cardiac output, especially during first trimester
Clinical classification of heart disease may worsen with pregnancy and lead to maternal death and/or stillbirth; closely monitor pregnant patients for destabilization of their heart failure
Pregnant women with symptomatic cirrhosis generally have poor outcomes including hepatic failure, variceal hemorrhage, pre-term delivery, fetal growth restriction, and maternal death
Outcomes are worse with coexisting esophageal varices; pregnant women with cirrhosis of liver should be carefully monitored and managed accordingly
Animal data
- In animal reproduction studies, the drug has been shown to cause unexplained maternal deaths and abortions in rabbits when administered orally during organogenesis at 4 times a human IV dose of 80 mg based on body surface area (BSA) and oral bioavailability corrections, presumably secondary to volume depletion
Lactation
Presence of the drug has been reported in human milk; there are no data on effects on breastfed infant or effects on milk production; doses of the drug associated with clinically significant diuresis may impair milk production; the developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for the drug and any potential adverse effects on breastfed infant from the drug or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
