Bendroflumethiazide is a diuretic, which means it helps your body get rid of extra salt (sodium) and water. It works by increasing the amount of urine (pee) you make. This can reduce symptoms such as swelling in your ankles or feet, or shortness of breath.
It is also called a 'water' tablet or 'water pill'.
Bendroflumethiazide is used to treat high blood pressure (hypertension), and is used to lessen extra fluid in the body (called oedema) caused by conditions such as heart failure, liver disease, or kidney disease.
In New Zealand, bendroflumethiazide is available as tablets (2.5 mg and 5 mg).
