Guidelines for Furosemide Use:

Medical professionals typically recommend furosemide dosages based on the patient’s condition, response to treatment, and underlying health factors. It is essential to monitor electrolyte levels, renal function, and blood pressure regularly during furosemide therapy to prevent potential complications.

Research on Furosemide:

A systematic review published in the American Journal of Medicine highlighted the efficacy of furosemide in managing acute decompensated heart failure, with significant improvements in fluid balance and symptom relief.

Statistical Data on Furosemide Use:
Condition Prevalence Treatment Response
Congestive Heart Failure Approximately 6 million adults in the US Positive response in 70-80% of cases
