How it works
Torsemide blocks sodium-potassium-chloride transport in the loop of Henle, increasing urine output and reducing excess fluid.
Important safety checks
Kidney and liver function, blood pressure, sodium, potassium, magnesium, gout and hearing symptoms require review. Anti-inflammatory painkillers, lithium and other blood-pressure or diuretic medicines can interact. Follow the treating team’s sick-day and weight-monitoring plan.
When to seek urgent care
Seek urgent help for fainting, severe confusion or weakness, a sustained irregular heartbeat, very low urine output, sudden hearing loss, severe breathlessness or facial swelling with breathing difficulty.
