What is Bendroflumethiazide?

Bendroflumethiazide is a prescription diuretic drug which is used to increase urine output. It relieves excess fluids (oedema) and hypertension (higher blood pressure). It increases urine output and is known as the 'water tablet'.

How does it work?

It is a thiazide diuretic. It inhibits the reabsorption of sodium in the kidneys. As more sodium is excreted from the kidneys, the water is also excreted to remove the salt. In this way, it helps to remove excess water from the body. 

Is the Bendroflumethiazide suitable for me?

It is suitable for babies, adults and children having the complaint of hypertension and fluid retention in the body. It is, however, not suitable if you are you allergic to it or if you are pregnant or breastfeeding. Consult with your doctor before using this medication.

How quickly do Bendroflumethiazide tablet works?

It works quickly. It starts working immediately, and you will need to visit the toilet after 1-2 hours of taking the first pill. The process then goes on.

What is the best time of day to take it?

Timing doesn't matter. However, it would help if you took it simultaneously every day. However, taking it in the morning will be a wise choice, and it may cause you to wake up at night for urination.

Should I drink more water while taking Bendroflumethiazide tablets?

It will cause more excretion of water from the body. However, excess excretion, particularly with decreased intake, can result in dehydration. Continue to take the routine water; however, consult the doctor in case of any relevant side effects.

Can Bendroflumethiazide cause weight gain?

It is less common. However, some regular users can complain of unusual weakness, weight gain, and a disturbance in blood sugar levels.

What causes my blood pressure to go high?

High blood pressure results from various pathological and lifestyle factors, e.g., obesity, diabetes, lack of physical activities, stressful routine, unhealthy foods and lifestyle etc. You need to address these issues along with taking the pills.

How much time do the Bendroflumethiazide tablets take to reduce oedema?

It will start working immediately, but the accumulated fluid will take more time to be excreted from the body. So, full removal takes days and even weeks as the fluid accumulation takes time.
