Lasix: Indications and Usage

Treatment of Edema

Lasix (furosemide) is indicated for the treatment of edema associated with congestive heart failure, cirrhosis of the liver, and renal disease, including the nephrotic syndrome. It is particularly useful when a diuretic with greater potential is desired. The usual initial dose is 20 to 80 mg given as a single dose, which can be adjusted based on the patient’s response.​

Management of Hypertension

For the treatment of hypertension, Lasix (furosemide) is used in adults either alone or in combination with other antihypertensive medications.​ Individualized therapy is essential to achieve the maximum therapeutic response while determining the minimal effective dose needed to maintain that response. The usual initial dose of Lasix for hypertension is 20 to 80 mg as a single dose.​ Dosage adjustments and additional doses may be necessary based on the patient’s response.​ Clinical observation and monitoring are crucial when administering doses exceeding 80 mg/day for extended periods٫ especially in elderly patients. In pediatric patients٫ the initial dose is weight-based٫ starting at 2 mg/kg body weight.​ Regular monitoring of blood pressure and potential interactions with other antihypertensive medications are recommended to achieve optimal management of hypertension.​

Dosage Recommendations

Lasix (furosemide) is dosed based on the patient’s individual response to achieve the maximum therapeutic outcome while determining the minimal effective dose required to maintain that response.​ In adults, the typical initial dose of Lasix for edema is 20 to 80 mg, which can be adjusted accordingly based on the patient’s condition.​ For hypertension, the usual initial dose is 80 mg, divided into 40 mg doses twice a day.​ Dosages may be increased or decreased depending on the patient’s response.​ Pediatric patients usually start with a weight-based initial dose of 2 mg/kg, which can be adjusted if needed.​

Use in Pediatric Patients

In pediatric patients, Lasix (furosemide) is indicated for the treatment of edema associated with congestive heart failure, cirrhosis of the liver, and renal disease, including the nephrotic syndrome.​ The initial dose is weight-based, typically starting at 2 mg/kg body weight.​ Dosage adjustments may be made based on the patient’s response, with careful monitoring recommended to achieve the desired therapeutic outcome.​

Adverse Effects and Precautions

Lasix (furosemide) may cause common side effects such as diarrhea, constipation, headache, and dizziness.​ However, more serious side effects can include allergic reactions, hearing loss, muscle cramps, and liver problems.
