What causes the Bendroflumethiazide side effects?

Bendroflumethiazide is a thiazide diuretic that works by reducing the amount of water in the blood, causing the patient to urinate more regularly. This works because it increases the levels of minerals and salts (namely potassium), which causes the excess water in the blood to be drawn out and transferred to the kidneys, where it is passed as urine. By decreasing the volume of liquid in the blood, it becomes easier for it to flow through the arteries, lowering the pressure on the blood vessels.

By altering the levels of potassium and other minerals in the body, Bendroflumethiazide can cause adverse reactions, specifically in people who suffer from other medical conditions or are taking other medication in conjunction with Bendroflumethiazide. Otherwise, this medication has been proven by UK registered doctors to be completely safe and highly effective. It is important to mention in your consultation any other relevant medical information.
