About Bendroflumethiazide

This belongs to the group of medicines known as Thiazide diuretics. Thiazide diuretics are often known as water tablets.

Bendroflumethiazide is used to treat hypertension (high blood pressure) and oedema (fluid retention), often caused by heart failure. It removes excess water from the body by increasing how often you urinate (pass water) and also widens the blood vessels which helps to reduce blood pressure.

Bendroflumethiazide is also sometimes spelt as bendrofluazide. You may notice the use of either spelling on the packaging of your medicine.

Bendroflumethiazide is available in tablet form.

It is also sometimes known as: Aprinox; Neo-NaClex. You may notice the use of any of these names on the packaging of your medicine.

• This medicine will make you urinate (pass water) more often, so your doctor or pharmacist will usually advise you to take your dose in the morning so as not to disturb your sleep. If you take more than one dose per day, take the last dose before 6pm in the evening.
• If you miss a dose, take it as soon as you remember. However, if it is after 6pm in the evening skip the missed dose and continue taking it at the usual times. Never take two doses at the same time to make up.
