here's what you need to know about long-term furosemide use and kidney function:

While furosemide is commonly used in IgAN patients to manage fluid retention, long-term high-dose use requires careful monitoring. It can potentially affect kidney function if not managed properly by:

Causing excessive fluid/electrolyte loss
Leading to dehydration and electrolyte imbalances
Risking acute kidney injury in some cases
However, kidney failure is not a direct effect when used appropriately. Key prevention steps:

Regular monitoring of kidney function
Maintaining proper hydration
Checking electrolytes routinely
Using the lowest effective dose
Following up with your doctor regularly
Always discuss any concerns about your furosemide dose with your healthcare provider - never adjust dosing yourself.
