Furosemide

Introduction To Furosemide

Furosemide belongs to a group of medicines called diuretics or water tablets. It is used to reduce the swelling (edema) caused by too much water in the body in people who have heart failure, liver or kidney disease. This medicine is also used to treat high blood pressure.

Furosemide helps your body get rid of extra water and salt through urine. It may be used alone or in combination with other medicines as per the dose advised by your doctor. It can be taken with or without food and should be taken at the same time each day. It is best to avoid taking this medicine within 4 hours of your bedtime to prevent having to get up at night to urinate.

It is important to continue taking this medication even if you feel well. If you stop taking it without consulting your doctor, your condition may worsen. Lifestyle changes like reducing stress, restricting salt intake, and stopping smoking may help this medication work better.

Common side effects of this medicine include hypotension, electrolyte imbalance, dehydration, decreased sodium level in blood, decreased potassium level in the blood, and decreased magnesium level in blood. These are usually mild and disappear after a short time. Consult your doctor if they bother you or do not go away.

Before taking this medicine, let your doctor know if you have any liver problems. Pregnant or breastfeeding women should also consult their doctor before taking it. Regular monitoring of kidney function tests and electrolyte levels is important while using this medicine. It may reduce the potassium level in your blood so your doctor may ask you to add potassium-rich foods to your diet (such as bananas, coconut water, etc.) or prescribe supplements.

Uses of Furosemide

Benefits of Furosemide

Treatment of Hypertension (high blood pressure)
Furosemide prevents your body from absorbing too much salt and allows the salt to be removed in your urine instead. It also helps get rid of excess water. This helps to lower your blood pressure and makes it easier for your heart to pump blood around your body. When your blood pressure is lower, you are less at risk of having a heart attack or a stroke. You should make appropriate lifestyle changes to help this medicine be effective and you need to take it regularly.

Treatment of Edema
Furosemide works by increasing the amount of urine produced. This helps your body get rid of extra water thereby relieving symptoms such as shortness of breath and swelling in your arms, legs, or abdomen. This will help you go about your daily activities more easily and make you more confident about being active. Take it regularly and make appropriate lifestyle changes to help this medicine be effective.

Frequently Asked Questions

Q. How is Furosemide different from Torasemide?

Both Furosemide and Torasemide are loop diuretics. They are used to treat high blood pressure and edema caused by an underlying liver, kidney or lung diseases. Unlike Torasemide, Furosemide is also used in the treatment of hypercalcemia (high calcium levels in the blood). Torasemide has a longer duration of action and is safer to use in patients with renal failure, as compared to Furosemide.

Q. Should you drink a lot of water when taking Furosemide?

It is advised to take an adequate amount of water if you are taking Furosemide. This is because Furosemide works by eliminating the extra fluid and electrolytes from your body by increasing the urine production. This elimination of fluids may increase the chances of dehydration if you sweat a lot, exercise vigorously or if the climate is hot. However, if you have kidney or heart problems, you must consult your doctor who will suggest the amount of water that you should be taking. Consult your doctor for any further query or concern.

Q. Can Furosemide cause weight gain?

No, Furosemide does not cause weight gain. On the contrary, you may lose weight as it makes your body get rid of the excess of fluids from your body.

Q. What if I take too much Furosemide?

If you take too much Furosemide, you may have certain side effects such as headache, irregular heartbeat, dizziness and temporary loss of consciousness. Additionally, you may notice increased thirst, causing frequent urination. Immediately contact your doctor if you notice any such side effects or feel unwell.

Q. How long will I need to take it for?

Furosemide should be taken in the dose and duration prescribed by the doctor. Depending on the illness you are being treated for, you may have to take it for a long term, even for the rest of your life. Do not stop taking Furosemide without consulting your doctor. Sudden discontinuation of the medicine may lead to worsening of your condition. For instance, your blood pressure may suddenly shoot up if you are taking it for hypertension (high blood pressure), or your swelling (edema) may worsen. However, if you require a dose adjustment or further assistance, consult your doctor.

Q. What other lifestyle changes should I make while taking Furosemide?

Lifestyle changes play a major role in keeping you healthy. Stop smoking and taking alcohol as this helps in lowering your blood pressure and preventing heart problems. Exercise regularly and take a balanced diet that includes whole grains, fresh fruits, vegetables and fat-free products. Avoid taking excess salt in your diet. Practice yoga or meditation and find ways to reduce or manage stress in your life. Ensure that you have a sound sleep every night as this also reduces your stress and hence helps in keeping your blood pressure normal. Consult your doctor if you need any further help to get maximum benefit of Furosemide and to keep healthy.

Q. Can I stop taking Furosemide if my blood pressure has lowered down?

No, you should not stop taking Furosemide even if your blood pressure is controlled. Sudden discontinuation of medicine may increase your blood pressure again and the chances of getting a heart attack and stroke may also increase. Consult your doctor if you are having any side effects or if you want to come off Furosemide. Your doctor may be able to prescribe a different medicine for controlling your blood pressure or may suggest ways to cope up with the side effects. You should understand that you need Furosemide to prevent further complications and therefore, you must not stop taking it without consulting your doctor.
