What are Bendroflumethiazide tablets?

Bendroflumethiazide is a medication that belongs to a class of drugs known as thiazide diuretics, more commonly referred to as 'water pills'. They are called water pills because they make you urinate more often.

Diuretics are medicines that promote and increase the excretion of urine.

It is a prescription-only medicine that is designed to treat the build-up of fluid in your body, including the fluid in your blood vessels, which can help to lower high blood pressure.

Bendroflumethiazide tablets are primarily prescribed to treat high blood pressure and the build-up of fluids in the body (Oedema).

You can buy Bendroflumethiazide from Medicine Direct, following an online consultation with one of our certified doctors. We sell this medicine in packets of either 28, 56, or 84 tablets, in doses of either 2.5mg or 5mg.

What is Bendroflumethiazide used to treat?

Bendroflumethiazide is commonly used to treat high blood pressure (hypertension).

High blood pressure is caused by a wide range of issues, including a family history of high blood pressure, smoking, obesity, age, lack of exercise and high levels of salt in your diet.

Certain health problems are also linked to it, including kidney disease and diabetes.

How does Bendroflumethiazide treat high blood pressure?

Thiazide Diuretics like Bendroflumethiazide tend to work directly on the kidneys and causes them to pass out more fluid. Thiazide Diuretics inhibit sodium absorption and as a result increases fluid loss in the urine, a process called diuresis.

Taking water tablets like Bendroflumethiazide make you need to urinate more often, which helps to get rid of excess fluid in your body. This also means that you will have less fluid in your blood vessels and body tissues, which helps to lower your blood pressure.

Thiazide Diuretics also have a dilating (widening) effect on the blood vessels which allows blood to flow through the circulatory system using less force from the heart. 

How to take Bendroflumethiazide

You will normally be instructed to take Bendroflumethiazide once a day, in the morning.

If your doctor prescribes Bendroflumethiazide to be taken twice a day, you should take it once in the morning and again around midday.

To ensure this medicine's effectiveness, try to make sure you are taking Bendroflumethiazide at the same time(s) every day.

Do not take thiazide diuretics after 4pm or in the evening; this medicine will make you need to go to the toilet, which will require you to wake up in the middle of the night.

Bendroflumethiazide tablets should be swallowed whole with a drink of water.

It can be taken with or without food.

Bendroflumethiazide dose
