How does bendrofluazide work?
Bendrofluazide acts on the kidneys, blocking the reabsorption of sodium and chloride (salt) back into the bloodstream. When excess salt is excreted in urine, water follows — reducing the total volume of fluid in your blood vessels. Less fluid means less pressure on artery walls, which lowers blood pressure. In oedema, this mechanism relieves the uncomfortable build-up of fluid in tissues such as the ankles, legs, and lungs.
↓ Salt : less sodium reabsorbed
↓ Fluid : water excreted in urine
↓ Volume : less blood vessel pressure
↓ BP : blood pressure falls
What is bendrofluazide used for?
High blood pressure (hypertension) — 2.5mg
One of the original first-line medicines for hypertension. At 2.5mg, it lowers blood pressure effectively over 24 hours with once-daily dosing and is often used alongside other blood pressure medicines such as ACE inhibitors, ARBs, or calcium channel blockers.
Fluid retention / oedema — 5mg
Relieves swelling caused by fluid accumulating in the body's tissues — commonly seen in heart failure, liver disease, kidney conditions, and certain medications. The 5mg dose provides a stronger diuretic effect for managing oedema.
Heart failure (as part of combination therapy)
Used alongside other heart failure medicines to reduce fluid overload, relieve breathlessness, and decrease the burden on the heart. Always prescribed as part of a broader treatment plan.
Dosage & how to take
| Hypertension dose | 2.5mg once daily in the morning |
| Oedema dose | 5mg once daily in the morning (may be given on alternate days for maintenance) |
| Why take in the morning? | The diuretic effect increases urination — morning dosing avoids disrupting your sleep |
| With or without food | Either is fine — swallow whole with a glass of water |
| Elderly patients | Start at the lowest effective dose — more sensitive to electrolyte changes |
| Missed dose | Take as soon as you remember in the morning; skip if it is afternoon or evening to avoid night-time urination |
Do not stop taking bendrofluazide suddenly without your doctor's advice — blood pressure may rise and fluid can accumulate rapidly if treatment is discontinued abruptly.

Key things to know before buying
Common side effects
Most side effects are mild and often settle as your body adjusts. Contact your doctor promptly if you experience severe muscle cramps, significant weakness, irregular heartbeat, or signs of gout — these may indicate low potassium or raised uric acid levels requiring attention.
