What is Bendroflumethiazide

Bendroflumethiazide, also available under the brand name Apronix, is a medication known as a diuretic or "water tablet". It used to lower high blood pressure and to treat fluid retention (oedema).

It is only obtainable on prescription and is available as a 2.5mg or 5mg tablets from Prescription Doctor.

To buy Bendroflumethiazide tablets online, simply complete our short online medical form and, if our doctor approves your order before 3pm, our UK registered pharmacy will send out your item the same day via a discreet next-day delivery service.

To begin your order, fill in our online consultation form for our doctor to review.

How Does Bendroflumethiazide Work?

While the diuretic effect of Bendroflumethiazide is understood, the hypotensive effects are not fully realised.

Bendroflumethiazide causes your kidneys to produce more urine and pass salts such as sodium and potassium.

Your kidneys filter your blood through specialised blood vessels, extracting nutrients, salts (sodium and potassium) and vitamins which can be used elsewhere in the body.

Salts such as potassium and sodium play a number of vital roles in your body - they help to retain water in your body to keep you hydrated and are used by smooth muscles. By causing your kidneys to flush out water and salt from your body, the amount of fluid in your blood vessels is reduced, which decreases your blood pressure.

Diuretics, such as Bendroflumethiazide, may be prescribed alongside another blood pressure lowering medication.

How Do I Take Bendroflumethiazide?

Your doctor will determine what dose you should be taking. This takes into account your reasons for taking it, your age and how well your kidneys work. Your dose may be lower if you are over 65 or have kidney problems.

Bendroflumethiazide is usually taken once a day in the morning. If you are prescribed it twice a day, is it best to take it once in the morning and once around midday.

You should try to take Bendroflumethiazide around the same time each day. If you have trouble remembering when to take medication, set a reminder on your phone.

Some people may only need to take Bendroflumethiazide two or three times a week. It should still be taken around the same time on the days you take it.

It is not advisable to take Bendroflumethiazide after 4pm or at night as you will likely disturb your sleep by causing you to wake up needing to use the toilet.

Bendroflumethiazide can be taken with or without food. Swallow tablets whole with a glass of water.

You should always take Bendroflumethiazide as prescribed by your doctor. If you are unsure how you should be taking Bendroflumethiazide, ask your doctor.

Your doctor may recommend taking Bendroflumethiazide alongside a healthy diet in order to efficiently lower your blood pressure.

Other safety information

It is important to inform our prescriber of all the medicines you are currently taking, including those bought-over-the-counter, prescribed by your doctor, as well as health and herbal supplements. This is to ensure our doctor can safely prescribe Bendroflumethiazide for you.

Never share your medicine with anybody else, even if they are experiencing the same symptoms or suffering from the same condition as you.

Getting the most out of treatment

Taking medication isn't the only way you can manage your high blood pressure. There are other changes you can make to your lifestyle in order to lower your blood pressure and improve your overall health.

First and foremost, it is important to eat a healthy low-fat diet. Aim to eat 5 portions of fruit and vegetables a day. Avoid eating more than 6g of salt per day.

Reduce your caffeine intake. Caffeine is usually consumed in beverages such as tea, coffee, cola and energy drinks. Make sure to drink plenty of water throughout the day.

Drinking excessive amounts of alcohol can increase your blood pressure over time, so it's a good idea to limit your alcohol consumption. Avoid drinking more than 14 units of alcohol per week. Alcoholic drinks are also high in calories and can contribute to weight gain.

Living an active lifestyle can help you manage your blood pressure. Even small changes can have a marked improvement in your overall health. Try walking more throughout the day by taking the stairs instead of the lift, walking or cycling to the shop, or getting off the bus a stop earlier and walking the rest of the way. Start with small exercises like walking or light jogging and build up to running or cycling.

If you are a smoker, quitting smoking can help you manage your blood pressure and reduce your risk of complications associated with high blood pressure, such as a heart attack or stroke.

Speak to your doctor for advice on managing high blood pressure. Your doctor can provide tailored advice, refer you to specialists or provide an action plan for you to follow in order to manage your condition.
