FAQ

Furosemide is a Schedule 4 prescription-only medicine in Australia, so a prescription is required when buying it from local pharmacies. Our store policy allows orders without a prescription, and the tablets can be sent by mail.

Store furosemide tablets at 20°C to 25°C. Excursions from 15°C to 30°C are permitted; protect the tablets from light and keep the container tightly closed.

Not necessarily. Tablets supplied under different brands or by different manufacturers can vary in colour, shape, size, markings and inactive ingredients, even when they contain furosemide in the same strength.

A changed appearance alone does not prove that the medicine is incorrect. Compare the active ingredient, strength, dosage form, manufacturer, package label, batch number, expiry date and any tablet imprint; do not use the tablets if the ingredient, strength, form or imprint appears wrong, or if the package is damaged.

Keep the package and check the labelled storage instructions, package integrity and tablet condition before use. Because the actual temperature and length of exposure are unknown, stability cannot be confirmed after a significant heat or cold event; seek advice from a pharmacist before using tablets that may have been affected.

Furosemide can cause dizziness, low blood pressure, blurred vision or reduced concentration, particularly when treatment starts or the dose changes. Do not drive or operate machinery until you know how it affects you.

These tablets are taken by mouth, exactly as directed for the individual treatment plan, with or without food. Because they increase urination, doses are often scheduled earlier in the day to reduce night-time trips to the toilet. The dose depends on the condition being treated, kidney function, fluid status and response.

Furosemide is a loop diuretic used to reduce oedema caused by conditions such as heart failure, liver disease or kidney disease. Oral furosemide can also be used to treat high blood pressure, alone or with other antihypertensive medicines.

Common effects include increased urination, thirst, dizziness and light-headedness. Excess fluid loss can cause dehydration, low blood pressure and electrolyte changes, including low potassium, which may cause muscle cramps, weakness or palpitations. Urgent assessment is needed for fainting, severe weakness, confusion, a severe rash, hearing changes or an irregular heartbeat.

NSAID pain medicines such as ibuprofen can reduce the diuretic effect and may increase kidney risk in susceptible people. Furosemide can also interact importantly with lithium, digoxin, blood-pressure medicines and medicines that affect hearing, such as some aminoglycoside antibiotics. A prescriber or pharmacist should review the full medicine list, including non-prescription products.

Description

What Is Lasix Used for?

Lasix (Furosemide), also known as a water pill, is a diuretic. It's frequently recommended to aid the body's urination of extra salt and water. It is sometimes used to treat illnesses including congestive heart failure, kidney issues, or high blood pressure to lessen edema and fluid retention. It boosts the body's excretion of water, salt, and chloride and raises urine production.

FUROSEMIDEHow the Medicine Looks Like

Tiny yellow or white tablets containing 20 or 40 milligrams of furosemide. Transparent liquid intended for intravenous injection.

Applications

Lasix causes the kidneys to produce more urine, lowering the body's water content. When this happens, blood pressure can be lowered, and water retention in the arms, legs, or lungs can be released. Additionally, Furosemide can aid in lowering blood calcium levels.

How to Take

Tablets should be taken with a small amount of water. Taking the tablets in the morning is recommended, followed by breakfast. If necessary, take your afternoon dosages by no later than 6 p.m.; if not, you might have to wake up in the middle of the night to use the restroom. You will receive an injection of Furosemide from your doctor or nurse.

Interactions

Interactions between Lasix and other drugs and substances may reduce its effectiveness or raise the possibility of adverse side effects. Here are a few typical interactions:

  1. Other Diuretics: Using diuretics simultaneously increases the risk of electrolyte imbalances and dehydration by having synergistic effects.
  2. Furosemide lessens the body's excretion of lithium, raising the body's lithium levels. Due to the potential for toxicity, lithium dosage adjustments may be necessary.
  3. Aminoglycoside Antibiotics: Lasix may raise the risk of ototoxicity (injury to the ears) and nephrotoxicity (damage to the kidneys) when used with aminoglycoside antibiotics (e.g., gentamicin).
  4. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): NSAIDs can lessen Furosemide's diuretic and antihypertensive effects. Kidney issues could also become more likely as a result of this interaction.
  5. Corticosteroids: Using corticosteroids concurrently can raise your risk of developing hypokalemia or low potassium levels.
  6. Digoxin: Furosemide may cause hypokalemia or other electrolyte imbalances, exacerbating digoxin's harmful effects on the heart.
  7. Antihypertensive Drugs: Furosemide and other antihypertensive drugs together may have a cumulative effect of decreasing blood pressure.
  8. A Few Anti-Diabetic Drugs: Furosemide may alter blood sugar levels and hinder certain anti-diabetic drugs' effects.
  9. Some Antiepileptic Drugs: The efficacy of certain antiepileptic medications may be diminished by Furosemide.

Before using Furosemide or any other new medication, it is important to inform your doctor about all the vitamins, over-the-counter medications, and prescriptions you are currently taking. This aids in evaluating possible interactions and modifying your treatment plan as necessary. Never change your drug schedule without first talking to your doctor.

What the Patient Should Know

Potassium can be lost from the body when taking this medicine. You can raise the amount of potassium in your body by consuming foods high in potassium, like oranges, bananas, or orange juice, or by taking a potassium supplement (as directed by your physician). Your dietician can assist you in selecting alternative foods high in potassium.

When you wake up in the morning, you may feel lightheaded or dizzy. Sit or lie down, then gently get to your feet. Dizziness may worsen in hot weather conditions or after consuming alcohol. Try consuming fewer alcoholic beverages, and steer clear of prolonged standing or sun exposure.

Furosemide may increase your skin's sensitivity to sunlight. Avoid the sun as much as you can. Wear eyewear and protective clothes, and apply sunscreen cream with an SPF of 30 or higher.

Take the missed dose of this medication as soon as you remember. Don't give yourself two doses, though, if it's time for the next dose.

Keep this medication out of children's reach and in a cold, dry location.

For any details regarding this drug, kindly contact your physician or nurse.

Warnings

Certain circumstances or contraindications dictate when it should not be used. The following are some typical contraindications:

This medicine or any of its parts should not be used by anyone who has shown signs of hypersensitivity or allergic reaction.

Since Lasix depends on urine production to get rid of extra fluid, it is not recommended for people who have anuria.

Lasix can potentially induce electrolyte imbalances, specifically a reduction in potassium levels. People who suffer from severe electrolyte imbalances might have to avoid taking it.

Lasix should be taken cautiously if someone is extremely dehydrated since it may make the condition worse.

The medicine may raise uric acid levels, which may lead to an attack of gout. Those with a history of gout may require special attention or different medicine.

It's possible that Lasix is unsafe to use while nursing or pregnant. In these circumstances, it's crucial to speak with a healthcare professional.

Furosemide should be used cautiously and, in certain situations, should not be used at all by those with specific medical conditions, such as liver disease.

Before taking Furosemide or any other drug, people should make sure their healthcare provider is aware of all of their medical history and current prescriptions. A medical practitioner is the only one who can assess if Furosemide is appropriate given a patient's unique medical circumstances.

Lasix Overdose

Overdosing can have significant side effects and needs to be treated right away. An excess of Furosemide may cause symptoms such as dehydration, hypokalemia, low potassium levels, low blood pressure, fainting, dizziness, lightheadedness, and ototoxicity.

In the event that an individual suspects overdosing or encounters adverse severe effects following Lasix administration, prompt emergency medical treatment should be sought. Depending on the overdose intensity and the symptoms, a specific strategy will be chosen.

How to Keep Lasix

It should be kept at room temperature. Steer clear of the sun and extremely hot weather.

It should be stored dry. It is advisable to store medication in a container with a tight lid because moisture can alter the medication's stability.

If you have kids or pets at home, keep Lasix out of reach and in a childproof container to avoid unintentional ingestion. For future reference, preserve the drug information and any instructions or patient pamphlets that the pharmacist or healthcare provider may have provided.

Verify the medication's expiration date on the container. Furosemide should not be used after the expiration date as it might not work as intended and might even be dangerous.

Customer questions

Asked by Mitchell W, Launceston, Australia

My furosemide tablets arrived in Launceston after the parcel was left outside during a very hot afternoon. What should I check before taking them?

Answered by Support team

Check the package label, container and tablets for damage, discolouration or other unusual changes, and confirm the storage instructions. The labelled storage range is 20°C to 25°C, with permitted excursions from 15°C to 30°C; because the actual heat and exposure time are unknown, do not use tablets that may have been affected until a pharmacist has advised you.

Asked by Lachlan, Alice Springs, Australia

I'm in Alice Springs rather than a major city. How can I check whether you can deliver furosemide tablets to my address?

Answered by Support team

Enter your delivery address and postcode at checkout to see the delivery options available for your location. Availability and delivery timing depend on the option selected and your address.

Asked by Sophie, Geelong, Australia

Before I pay, can I use my Geelong postcode to check whether furosemide tablets can be delivered to me?

Answered by Support team

Asked by Ethan, Adelaide, Australia

I've just placed an order but selected the wrong strength. Can I change it before it is sent?

Answered by Support team

You can request a change or cancellation before the order has been dispatched. Once it has been sent, it can no longer be modified.

Asked by Priya, Townsville, Australia

I have type 2 diabetes and may be starting furosemide for ankle swelling. Could it affect my blood glucose readings?

Answered by Support team
Medical reviewed by Lynette Ellis

It can. Furosemide may reduce glucose tolerance, raise blood glucose or unmask previously undetected diabetes, so glucose monitoring may need closer attention when treatment starts or changes.
