Bendroflumethiazide works by disrupting the transport of salt and water across certain cells in the kidneys, according to Patient.co.uk. This causes the kidneys to pass more urine, reducing the blood pressure and stress on the heart. Used as a diuretic, bendroflumethiazide is commonly prescribed to clear excess fluids from the body and as a treatment for hypertension.
Bendroflumethiazide is often taken together with other medications and for this reason is commonly prescribed in a combination tablet to prevent the need for taking an excessive number of pills throughout the day, according to Patient.co.uk. Belonging to a family of medications called thiazide diuretics, bendroflumethiazide is often called a water tablet.
Bendroflumethiazide is not suitable for people who are pregnant, breastfeeding or suffering from gout, lupus, kidney disease or Addison's disease. Because bendroflumethiazide reacts with many drugs, including herbal medicines, it is important for a patients to disclose to his doctor all pills he currently takes before beginning any treatment using bendroflumethiazide. Bendroflumethiazide can be taken before or after meals; however, it is very important to follow any additional instructions received by a doctor as to what time of day to take the medication. Because bendroflumethiazide increases the production of urine, patients are most commonly advised to take it early in the morning to avoid the disruption of sleep during the night.
