How Does Bendroflumethiazide Work?
Bendroflumethiazide is a thiazide diuretic. It affects the way that the kidneys handle salt and water, drawing more water out of the blood into the kidney to be passed out of the body as urine. Getting rid of more fluid helps to both lower the blood pressure and prevent fluid retention in the lungs and peripheries such as the feet and legs. This can help to reduce painful foot and leg swelling.
How is Bendroflumethiazide Taken?
Bendroflumethiazide is a tablet that should be taken in the morning. It is best to avoid taking it at night, as this can lead to the inconvenience of needing to pass urine overnight.
The tablet should be swallowed with some water.
What is the dosage of Bendroflumethiazide?
When treating fluid retention, the usual starting dose of Bendroflumethiazide is 5-10mg each morning. Occasionally, some patients are advised to only take the tablet every other day or three times a week.
When treating high blood pressure, the usual dose is 2.5mg taken every day.
