What is Bendroflumethiazide and how does it work?

A diuretic is a type of drug that includes bendroflumethiazide. It is used to treat high blood pressure (hypertension) and fluid retention in the body (oedema).

Diuretics are sometimes referred to as “water pills” since they encourage you to pee more frequently. This implies there is less fluid in your tissues, which aids in the removal of swelling and fluid build-up in the body (oedema). There will be less fluid in your blood, which will assist to lower your blood pressure.

Only prescriptions for bendroflumethiazide are available. It comes in the form of tablets or a liquid that you ingest.

What is the mechanism of action of bendroflumethiazide?

Bendroflumethiazide works by increasing the quantity of water and salt that your kidneys excrete through your urine. Because too much salt and fluid build-up in your blood vessels can cause high blood pressure, Bendroflumethiazide reduces your blood pressure by draining it out.

What are some of the advantages of using Bendroflumethiazide?

Hypertension (high blood pressure) is caused by a multitude of variables, including family history, a high-salt diet, and being overweight or inactive.

In addition to making some lifestyle adjustments (such as smoking and/or drinking less and exercising more), it’s common to be prescribed medication, such as Bendroflumethiazide, to help control the disease and avoid more serious problems including stroke, heart attack, and blood clots.

What is the best way to take Bendroflumethiazide?

Bendroflumethiazide is only available with a doctor’s prescription. Always listen to your doctor’s instructions and read the patient information booklet that comes with your prescription.

Swallow the tablets whole with a glass of water, with or without meals. You should take it in the morning at the same time every day.

Dosage of bendroflumethiazide

Bendroflumethiazide tablets contain the active component bendroflumethiazide in 2.5mg or 5mg concentrations.

The recommended starting dose is one 2.5mg pill per day, which may be raised by your doctor if necessary. If you are elderly, you may be given a lower initial dose, and the dose will be different if you are using this medicine to treat fluid retention rather than high blood pressure.

Unless your next dose is approaching, if you forget to take a Bendroflumethiazide pill, take it as soon as you recall. In this situation, simply skip the forgotten one because you should never increase your dose to compensate for a missing one.

If you take more Bendroflumethiazide than you should, see your doctor or go to the local emergency room right away. You may have overdose symptoms such as thirst, increased urine frequency and volume, and changes in your blood salt levels.

When using bendroflumethiazide, how much water should I drink?

While taking bendroflumethiazide, it’s usually advisable to drink normally. A decent rule of thumb is to drink enough fluid to avoid being thirsty for long periods of time.

When you’re exercising or it’s hot outside, gradually increase the amount you drink. You’re probably consuming enough fluid if your pee is pale yellow or clear.

If you have heart failure or kidney difficulties, though, you may need to reduce your fluid intake. Your doctor or nurse will advise you exactly how much water you need to drink each day in this scenario.

How do you deal with it?

Bendroflumethiazide can be taken with or without food. Consume the pills completely with a glass of water. Make sure you shake the bottle well if you’re taking bendroflumethiazide as a liquid. To help you measure the exact amount, it will come with a plastic spoon or syringe. Ask your pharmacist if you don’t have one. Do not use a kitchen teaspoon to measure the liquid because it will not give you the correct amount.

What should you do?

With or without food, you can take bendroflumethiazide.

Take a sip of water and swallow the tablets whole.

Consult your pharmacist if you don’t have one. Do not use a kitchen teaspoon to measure the liquid because it will not be accurate.

What happens if I overdo it?

Dehydration can be caused by too much bendroflumethiazide, which can induce weak or fast heartbeats, fits (seizures), disorientation, and confusion.

The amount of bendroflumethiazide that might cause an overdose varies depending on the individual.

Negative effects

Bendroflumethiazide, like all drugs, can have adverse effects, though not everyone experiences them.

If you take a low amount, such as 2.5mg daily, you are less likely to experience negative effects.

As your body adjusts to the medication, the side effects usually improve.

Breastfeeding and pregnancy

In most cases, bendroflumethiazide is not suggested during pregnancy. Your doctor, on the other hand, may prescribe it if the advantages of the medicine outweigh the hazards.

Talk to your doctor about the advantages and risks of taking bendroflumethiazide if you’re trying to get pregnant or are already pregnant.

It depends on how far along you are in your pregnancy and why you’re taking the prescription. There may be other options available to you that are less damaging..

Breastfeeding and bendroflumethiazide

When breastfeeding, bendroflumethiazide isn’t usually recommended. It may cause you to produce less breast milk.

Other medicines may be better while you’re breastfeeding, so talk to your doctor. If you’re: 

  • Attempting to get pregnant
  • Pregnant
  • Breastfeeding

Contraindications with other medications

Some drugs can make bendroflumethiazide less effective.

Before starting bendroflumethiazide, tell your doctor if you’re taking any of the following medications:

  • for pain treatment, non-steroidal anti-inflammatory medications (NSAIDs) such as ibuprofen or naproxen, or aspirin
  • Amiodarone, digoxin, disopyramide, flecainide, and sotalol are some of the medications used to treat heart issues.
  • Antiemetics, such as domperidone, metoclopramide, and prochlorperazine, are used to treat nausea and vomiting.
  • Amitriptyline, citalopram, and venlafaxine are antidepressants.
  • medicines that affect the levels of salts (electrolytes) in your blood, such as potassium, sodium, calcium, and magnesium, corticosteroids, or other diuretics 
  • medicines used for asthma, such as inhalers such as formoterol, salbutamol, or salmeterol 
  • Other mental health medications include chlorpromazine, pimozide, trifluoperazine, and lithium.
  • Potassium, sodium, calcium, and magnesium, as well as corticosteroids and other diuretics, impact the levels of salts (electrolytes) in your blood.
  • Allopurinol is a gout medication.
  • The drug cyclosporine is used to treat psoriasis and rheumatoid arthritis.
  • insulin or any other type of diabetes medication
  • Epilepsy medication carbamazepine
  • Supplements containing calcium or vitamin D, such as alfacalcidol or calcitriol

When I’m sick, is it safe to take bendroflumethiazide?

If you experience diarrhea or vomiting as a result of a stomach bug or another sickness, contact your doctor or a pharmacist. You may need to temporarily stop taking bendroflumethiazide until you are able to eat and drink properly again.

Is it OK for me to take bendroflumethiazide before my surgery?

If you’re having a major procedure – such as a cesarean section – without a general anesthetic, tell your doctor you’re taking bendroflumethiazide.

When combined with a general anesthetic, bendroflumethiazide can lower blood pressure. Stopping bendroflumethiazide 24 hours before surgery may be recommended by your doctor.

Will it have an impact on my contraception?

Any type of contraception will not be affected by bendroflumethiazide.

Some hormonal contraception methods, such as the combination pill and contraceptive patch, are not suggested for women with high blood pressure. If you’re using a hormonal contraceptive, talk to your doctor.

Will it have an impact on my fertility?

There is no conclusive evidence that bendroflumethiazide reduces fertility in either men or women. Bendroflumethiazide can cause erectile dysfunction (impotence) in men in rare situations. If you’re having trouble attaining or keeping an erection, talk to your doctor. If bendroflumethiazide is to blame, symptoms normally improve within a few weeks of quitting the medication. Before using bendroflumethiazide, talk to your pharmacist or doctor if you’re attempting to get pregnant.

Is it possible for me to drive or ride a bike?

Bendroflumethiazide can cause dizziness. If this happens to you, wait until you feel better before driving, riding a bike, or using tools or machinery.

Is it okay if I combine it with beer?

Alcohol might cause you to feel dizzy or lightheaded by altering your blood pressure.

Before you consume any alcohol during the first few days of taking bendroflumethiazide or after increasing the dose, evaluate how the medicine affects you.

If you’re in good health, you can drink alcohol in moderation by sticking to the national limits of 14 units per week for males and 14 units per week for women. Two units equal a regular glass of wine (175ml). In most cases, a pint of lager or beer contains 2 to 3 units of alcohol.

It’s advisable not to drink a lot of alcohol when taking bendroflumethiazide if you have high blood pressure. It has the potential to elevate your blood pressure, make you dizzy, and cause dehydration.

Is there anything I should stay away from in terms of food or drink?

When taking bendroflumethiazide, low-salt (or low-sodium) diets are not recommended because the medication might produce low salt levels in the body.

Tea, coffee, cola, and energy drinks are all caffeinated liquids that should be avoided. They can amplify the effects of bendroflumethiazide, causing you to pee more frequently.

Switching to decaffeinated drinks and drinking enough other fluids, such as water or squash, will help you cut down on your caffeine intake.

Can a change in lifestyle help?

Making several critical lifestyle adjustments can help you improve your overall health, as well as the health of your heart. If you have high blood pressure or heart failure, they will also assist.

  • Smoking cessation – Cigarettes raise your blood pressure and heart rate. Quitting smoking lowers blood pressure and alleviates the symptoms of heart failure. Also, try to stay away from secondhand smoke.
  • Reduce your alcohol consumption – excessive alcohol consumption boosts blood pressure and worsens heart failure. If you have high blood pressure, you should avoid consuming excessive amounts of alcohol on a daily basis because it can elevate it.
  • Regular exercise helps to keep your heart and blood arteries in good shape, which decreases blood pressure. It doesn’t have to be very strenuous; daily walks can assist.
  • Eat a healthy diet rich in fruits and vegetables, whole grains, fat-free or low-fat dairy products, and lean proteins. Salt reduction is also a good idea. The most common reason for high blood pressure is excessive salt consumption; the more salt you consume, the higher your blood pressure will be. Limit your daily salt intake to 6 grams.
  • Deal with stress – when you’re anxious or upset, your heart races, you breathe faster, and your blood pressure often rises. This can aggravate heart failure. Look for strategies to alleviate stress in your life. Try sleeping or putting your feet up whenever possible to give your heart a break. To stay social and minimize stress, spend time with friends and family.
  • Vaccinations – If you have heart failure, you should have a flu shot every year and a pneumonia vaccine (commonly known as the pneumococcal vaccine) every five years. 

If you’re suffering from oedema, you can also try:

extending your legs 3–4 times a day to enhance circulation while avoiding long durations of standing

What happens if I stop using it?

Your blood pressure is likely to rise if you stop taking it. If you’re taking bendroflumethiazide to treat a fluid build-up (edema), you might notice that the additional fluid builds up again.

Salt (electrolytes) levels in your blood may also vary. After a week or two, your doctor may recommend a blood test to confirm this.

Is it healthy to use for a long period of time?

Bendroflumethiazide is safe to use for a long time, but you’ll need to visit your doctor or nurse for blood and urine tests on a regular basis. This is to ensure that the chemicals in your blood are in good working order.

The frequency with which you’ll require these tests will be determined by the reason you’re taking bendroflumethiazide if your dose has recently changed, and whether you have any other health issues.

Use of consumer information

If your symptoms or health concerns do not improve or worsen, consult your doctor.

Don’t share your medications with others, and don’t take other people’s medications.

Another patient information leaflet may be available for some medications. Consult your pharmacist for more information. Please consult your doctor, nurse, pharmacist, or other health care practitioner if you have any questions regarding bendroflumethiazide.

If you think you’ve taken too much, consult your state poison control center or seek medical help right immediately. Prepare to explain or demonstrate what was stolen, how much was taken, and when it occurred.
