Drug Class: Loop diuretics

Uses Warnings Before Taking Dosage Side effects Interactions

Usual Adult Dose for Ascites

Oral:
50 to 200 mg orally per day in 1 to 2 divided doses; once effective diuresis has been achieved, adjust dose as needed in 25 to 50 mg increments to the minimum effective dose and give on a continuous or intermittent schedule.

Add-on dose: When adding this drug to an existing diuretic regimen, initial dose and dose changes should be in 25 mg increments.

Comments:

  • Initial and maintenance doses as high as 200 mg twice a day may be required, mostly in patients with severe, refractory edema.
  • Dose and frequency can usually be reduced once dry weight has been achieved.
  • Intermittent dosing may consist of alternate daily dosing or more prolonged periods of diuretic therapy interspersed with rest periods.

Use: Management of edema when an agent with greater diuretic potential than those commonly employed is required for treatment of edema associated with congestive heart failure, liver cirrhosis, or renal disease, including nephrotic syndrome, or short-term management of ascites due to malignancy, idiopathic edema, or lymphedema.

IV:
50 mg (or 0.5 to 1 mg/kg) IV once; occasionally, a second dose at a new injection site may be required.

Comments: A single dose not exceeding 100 mg has been used in critical situations.

Use: When rapid onset of diuresis is desired (e.g., acute pulmonary edema) or when gastrointestinal absorption is impaired or oral medication is not practicable.

1 year or older:

  • Initial dose: 25 mg orally
  • Maintenance dose: May adjust dose as needed in 25 mg increments.

  • Use: Management of edema when an agent with greater diuretic potential than those commonly employed is required for short-term management of edema associated with congenital heart disease or nephrotic syndrome in hospitalized patients.

Renal Dose Adjustments

If increasing electrolyte imbalance, azotemia, and/or oliguria occur during treatment of severe, progressive renal disease: Discontinue this drug.

Liver Dose Adjustments

Dose Adjustments
