Furosemide
Furosemide is a loop diuretic that increases salt and water excretion. It can also cause dehydration, kidney impairment and significant electrolyte changes.
Key takeaways
- Extra tablets are not a safe response to swelling or a high blood-pressure reading without clinical direction.
- Vomiting, diarrhoea, poor intake or heat can increase dehydration and kidney risk.
- Low sodium, potassium or magnesium can cause weakness, confusion, cramps or abnormal rhythm.

What furosemide is used for
Uses include selected oedema and sometimes hypertension. The cause of fluid retention determines treatment.
Important safety checks
Review kidney or liver disease, gout, diabetes, low blood pressure, pregnancy and medicines such as NSAIDs, lithium, digoxin or other diuretics. Monitor weight, blood pressure, kidney function and electrolytes as directed.
When to seek urgent care
Seek urgent help for fainting, severe confusion, seizure, a new irregular heartbeat, very little urine, sudden hearing change, facial swelling or breathing difficulty.
