How long does it take Lasix (40 mg) to start working?

After I take my first dose of lasix (Furosemide) how long will it take before I have more urine production? Took it this morning but no increase in volume or frequency.

Thank you.

It's supposed to take about 30 minutes. IDK if it's supposed to build up in your system or not. Keep taking it and it should start working.
