Furosemide
In brief
- Furosemide tablets from Leader Pharma come in 40mg (60, 90, 120, 240 or 360 per pack) and 100mg (60 to 360 per pack), and orders are delivered across the UK in 9–21 days.
- As a fast-acting water tablet, it blocks salt reabsorption in the loop of Henle, so urine output usually rises within an hour and the effect lasts around six hours.
- UK doses for high blood pressure are typically 20–80 mg a day, while oedema is commonly managed with 20–40 mg each morning; the 100mg size is not licensed in the UK.
- Your prescriber will check urea and electrolytes regularly, since furosemide can lower potassium, sodium and magnesium, and may raise uric acid or blood sugar.
- It should not be used if you are severely dehydrated or passing no urine; taking it early in the day avoids night-time trips to the toilet, and it is a POM in the UK.
