Uses of Lasix Injection

Benefits of Lasix Injection

Treatment of Hypertensive emergency
Lasix Injection blocks the effect of some chemicals on your heart and blood vessels. This slows down the heart rate and helps the heart beat with less force thereby lowering your blood pressure. This medicine is injected into a vein under the supervision of a doctor. It is used for immediate reduction of very high blood pressure (hypertensive emergency). A controlled blood pressure reduces the risk of having a heart attack, stroke, or kidney problems.

Treatment of Edema
Lasix Injection 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. Lasix Injection is given as an injection by a doctor in the dose and duration that is best for you. This medicine should not be self-administered. Follow your doctor’s instructions carefully and make appropriate lifestyle changes to help this medicine be effective.

Frequently asked questions

How is Lasix Injection different from Torasemide?

Both Lasix Injection 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, Lasix Injection 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 Lasix Injection.

Should you drink a lot of water when taking Lasix Injection?

It is advised to take an adequate amount of water if you are taking Lasix Injection. This is because Lasix Injection 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.

What is Lasix Injection used for?

Lasix Injection is used in emergency conditions to lower very high blood pressure (hypertensive crisis). It effectively lowers and normalizes blood pressure rapidly, thus preventing heart attack or stroke. It also helps to remove excess fluids and electrolytes from the body and reduces swelling (edema) due to fluid retention.

What are the side effects of Lasix Injection?

The most common side effects of Lasix Injection are dizziness, weakness, dehydration, decreased potassium and magnesium levels in blood and increased thirst. You may also notice some injection site reactions such as swelling, pain and redness. However, these are temporary and usually resolve on their own. Consult your doctor if the symptoms persist for long or worry you.

How long does a Lasix Injection last?

A. Lasix Injection starts acting as early as five minutes and its effect lasts for about two hours. Lasix Injection may cause depletion of sodium, chloride, water and other minerals from the body. Therefore, close monitoring is required if a person is being treated with Lasix Injection.

What other lifestyle changes should I make while taking Lasix Injection?

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 Lasix Injection and to keep healthy.

Can Lasix Injection cause weight gain?

No, Lasix Injection 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.
