Furosemide (Frusemide) in Australia: A Doctor’s Review of the Diuretic That Can Restore Comfort, Breathing and Independence
By an Australian physician
If you are over 30 and have ever felt that your ankles are swollen by evening, your shoes feel too tight, your breathing becomes laboured when you walk to the letterbox, or you wake at night gasping for air, you may be living with fluid overload. These symptoms are not simply “getting older”. They can be signs of heart failure, kidney disease, liver cirrhosis or difficult-to-control high blood pressure. Left untreated, they can lead to repeated hospital admissions, reduced mobility and loss of independence.
As a doctor practising in Australia, I often prescribe furosemide—also spelled frusemide in Australia and sold under familiar trade names such as Lasix, Uremide and Frusid. It is a potent loop diuretic that has been trusted for decades because it works rapidly and predictably. This article explains how furosemide works, answers common safety questions, and shows why it remains one of the most practical and cost-effective medicines available on the Pharmaceutical Benefits Scheme (PBS).
Attention: Recognise the Warning Signs That Furosemide Can Help
Do any of these sound familiar?
- Swollen feet, ankles or legs that leave sock marks and make shoes uncomfortable by late afternoon.
- Shortness of breath when lying flat, or waking at night feeling suffocated.
- Rapid weight gain over a few days without eating more.
- A swollen, heavy abdomen that makes bending over difficult.
- High blood pressure that remains elevated despite medication.
- Fatigue and reduced exercise tolerance because excess fluid makes the heart work harder.
These are not trivial complaints. They are distressing, exhausting and frightening. Many patients tell me they feel trapped in their own bodies, afraid to leave the house because of breathlessness or urgent bathroom trips. The good news is that furosemide can often relieve these symptoms quickly—sometimes within 30 to 60 minutes of an oral dose.
Interest: What Is Furosemide and Why Do Australian Doctors Trust It?
Furosemide belongs to a class of medicines called loop diuretics. It works on a specific part of the kidney called the loop of Henle. There, it blocks the reabsorption of sodium, chloride and water. As a result, the kidneys turn excess salt and water into urine. This reduces the amount of fluid in the lungs, legs, abdomen and blood vessels, which lowers blood pressure and makes breathing easier.
Because furosemide is fast-acting and dose-adjustable, it is used in Australian hospitals and general practice for acute pulmonary oedema, chronic heart failure, resistant hypertension, and oedema caused by liver or kidney disease. It is registered by the Therapeutic Goods Administration (TGA) and is widely available as a PBS-subsidised medicine, making it affordable for most Australians.

Desire: Your Questions Answered by a Doctor
Many patients—especially those over 50—ask me detailed questions about furosemide and specific health conditions. I want to address those directly, because understanding the answers can reduce anxiety and help you feel confident about treatment.
| Question | Doctor’s answer | Key safety tip |
|---|---|---|
| Can furosemide be used in patients with vascular dementia? | Yes, with caution. Furosemide is not a dementia treatment, but many people with vascular dementia also have heart failure or high blood pressure. Careful diuresis can relieve breathlessness and leg swelling, which may reduce agitation, improve sleep and help the person feel more comfortable. However, over-diuresis can cause dehydration, low blood pressure and electrolyte imbalance, which may worsen confusion. | Use the lowest effective dose. Monitor weight, kidney function, sodium and potassium regularly. Avoid sudden, large fluid shifts in frail older people. |
| Does furosemide cause a change in serum protein? | Furosemide does not directly damage protein production. In the first days of treatment, it removes water from the bloodstream, which can cause haemoconcentration—meaning the blood becomes more concentrated and the serum protein level may appear to rise slightly. If your serum protein is low, the cause is usually the underlying illness, such as liver disease, kidney disease or malnutrition, not furosemide itself. | Do not blame furosemide for low albumin or total protein. Your doctor will investigate the underlying condition if serum protein is persistently abnormal. |
| Does furosemide cause a decrease in white blood cell count? | Rarely, yes. Furosemide can cause blood disorders such as leukopenia, neutropenia, agranulocytosis or thrombocytopenia, but these are uncommon. The risk is not a reason for most patients to avoid the drug. | Seek immediate medical review if you develop fever, severe sore throat, mouth ulcers or signs of infection while taking furosemide. A full blood count can be checked and the medicine stopped if needed. |
| Does furosemide cause a decrease in urine output? | No. Furosemide is designed to increase urine output. If you notice a decrease in urine after starting furosemide, that is a warning sign—not a normal response. It may indicate dehydration, low blood pressure, worsening kidney function, urinary obstruction or anuria. | If urine output drops significantly or stops, stop the medicine and seek urgent medical care. This is especially important in hot Australian weather when dehydration is more likely. |
| Can furosemide be used for oedema in liver cirrhosis? | Yes. Furosemide is frequently used for ascites and leg oedema caused by liver cirrhosis. However, it is usually combined with another diuretic called spironolactone. In cirrhosis, overly rapid fluid removal can trigger hepatic encephalopathy, kidney impairment or dangerous electrolyte disturbances. | Treatment should be started slowly, often in hospital for severe ascites. Australian specialists typically aim for gradual weight loss—no more than 0.5–1 kg per day depending on oedema. Never increase the dose on your own. |
| Is furosemide safe in patients with anuria? | No. Anuria means the kidneys are producing no urine at all. Furosemide cannot work if there is no urine output. It is contraindicated in anuria and may worsen the situation by causing fluid overload or electrolyte imbalance. | Furosemide should not be used in patients who are anuric. If you are passing no urine, this is a medical emergency that requires hospital assessment, not a water tablet. |
| Does furosemide affect the efficacy of antihypertensives? | Furosemide generally enhances—not reduces—the blood pressure lowering effect of other antihypertensives. In some patients this additive effect is beneficial, especially in resistant hypertension. However, it can sometimes lower blood pressure too much, causing dizziness, falls or fainting. | Your doctor may reduce the dose of your other blood pressure medicines when starting furosemide. Monitor blood pressure at home and report light-headedness. Avoid non-steroidal anti-inflammatory drugs such as ibuprofen, which can blunt the effect of furosemide and stress the kidneys. |
| Can furosemide be used in patients with acute glomerulonephritis? | Furosemide may be used to manage fluid overload, high blood pressure and oedema in acute glomerulonephritis, but it does not treat the glomerular inflammation itself. Use is usually undertaken in hospital under specialist supervision because the kidneys are already inflamed and over-diuresis can cause further injury. | If you have acute glomerulonephritis, furosemide should only be used with close monitoring of kidney function, electrolytes and urine output. It is a supportive treatment, not a cure for the kidney inflammation. |
Why Patients Feel Better on Furosemide
In my clinical experience, patients who start furosemide for the right indication often describe several life-changing benefits:
- Breathing becomes easier because fluid is removed from congested lungs.
- Legs and ankles slim down, so shoes fit again and mobility improves.
- Hospital admissions are reduced because fluid overload is kept under control.
- Blood pressure improves, often allowing a reduction in other medications.
- Energy and sleep improve once night-time breathlessness and swelling resolve.
Furosemide is not a cure for the underlying disease, but it is one of the most effective symptomatic treatments we have. When used correctly, it can help you remain at home, stay active and avoid the revolving door of emergency department visits.
Action: How to Access Furosemide in Australia
If you recognise the symptoms described in this article, the next step is to speak with your doctor. Furosemide is a prescription-only medicine in Australia, so it cannot be purchased over the counter. But with a PBS prescription, it is inexpensive and widely available at every Australian pharmacy.
- Book an appointment with your GP or specialist. Discuss your symptoms of swelling, breathlessness, fatigue or blood pressure control.
- Ask whether furosemide is suitable for you. Your doctor will assess your heart, kidney and liver function, check your blood pressure and review your medications.
- Have baseline blood tests. These usually include kidney function, electrolytes, full blood count and sometimes liver function tests. These help ensure safe use.
- Get your prescription filled. Take it to any Australian pharmacy. Ask the pharmacist for the Consumer Medicines Information leaflet.
- Weigh yourself daily. A sudden weight gain of more than 1 kg in a day or 2 kg in 2 days may mean fluid is building up. Report this to your doctor.
- Keep your follow-up appointments. Your doctor will titrate the dose and monitor blood tests, especially potassium and kidney function.
Seek urgent medical help if you experience: marked dizziness or fainting, confusion, severe cramping, palpitations, reduced or absent urine output, fever with sore throat, or worsening breathlessness.
Final word from the doctor: Furosemide has stood the test of time because it works. It is not right for every patient, and it must be used carefully—especially in people with dementia, liver disease or kidney disease. But for the right person, it can be the difference between struggling to breathe and walking comfortably to the shops. If you are tired of living with fluid overload, talk to your doctor today about whether furosemide belongs in your treatment plan.
