What this medicine is used for

The name of your medicine is APO-Frusemide. It contains the active ingredient furosemide (frusemide).

Furosemide (frusemide) is used to treat swelling of the ankles, feet, legs or even the brain or lungs. This swelling is called oedema and can occur in some heart, lung, liver or kidney conditions.

Furosemide (frusemide) may be used in some patients with more serious kidney problems who may have some fluid retention.

Furosemide (frusemide) may also be used to lower high blood pressure (which is also called hypertension).

Everyone has blood pressure. This pressure helps move your blood around your body. Your blood pressure may be different at different times of the day, depending on how busy or worried you are. You have hypertension (high blood pressure) when your blood pressure stays higher than is needed, even when you are calm and relaxed.

If high blood pressure is not treated it can lead to serious health problems, including stroke, heart disease and kidney failure.

Furosemide (frusemide) may be taken alone or in combination with other medicines to treat your condition.

Your doctor may have prescribed furosemide (frusemide) for another purpose.

Ask your doctor if you have any questions about why it has been prescribed for you.

This medicine is only available with a doctor's prescription.

How it works

Furosemide (frusemide) belongs to a family of drugs called diuretics. A diuretic helps reduce the amount of excess fluid in the body by increasing the amount of urine produced.

This medicine is not addictive.

How to take this medicine

Follow the directions given to you by your doctor carefully.

Their instructions may be different to the information in this leaflet.

How much to take

Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.

Do not stop taking your medicine or change your dosage without first checking with your doctor.


Adults: 20 to 80 mg as a single dose. The dose may be increased in exceptional cases up to 400 mg per day.

Children: 2 mg per kg bodyweight per day. The dose may be increased by 1-2mg per kg and should not exceed 6mg per kg bodyweight.

How to take it

Swallow furosemide (frusemide) tablets with a glass of water.

When to take it

Furosemide (frusemide) tablets are usually taken once or twice a day.

Take furosemide (frusemide) tablets on an empty stomach. For example, one hour before food or two hours after food. Food can interfere with the absorption of furosemide (frusemide) tablets.

Take furosemide (frusemide) tablets at about the same time each day unless your doctor tells you otherwise.

Taking your medicine at the same time each day will have the best effect. It will also help you remember when to take the medicine.

If you are taking a single dose a day, take it in the morning, for example before breakfast. If you are taking more than one dose a day, take the last dose no later than 2 pm, unless your doctor tells you otherwise.

Furosemide (frusemide) may increase the amount of urine you pass; it will also increase the number of times you need to go to the toilet. By taking your last dose around 2 pm, there may be less chance that your sleep is disturbed.

How long to take it for

Continue taking your medicine for as long as your doctor tells you.

Ask your doctor if you are not sure how long to take the medicine for.

If you forget to take it

This may increase the chance of getting an unwanted side effect.

If it is almost time for your next dose, skip the dose you missed and take the next dose when you are meant to.

If there is still a long time to go before your next dose, take it as soon as you remember, and then go back to taking it as you would normally.

Do not take a double dose to make up for missed doses. If you are not sure what to do, ask your doctor.

If you have trouble remembering when to take your medicine, ask your pharmacist for hints to help you remember.

If you take too much (overdose)

Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at your nearest hospital, if you think you or anyone else may have taken too much furosemide (frusemide).

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

If you take too much furosemide (frusemide), you may feel confused, dehydrated, dizzy or you may pass excessive urine.

While you are taking this medicine

Things you must do

Tell your doctor that you are taking this medicine if:

  • you are about to be started on any new medicine
  • you are pregnant or are planning to become pregnant
  • you are breastfeeding or are planning to breast-feed
  • you are about to have any blood tests
  • you are going to have surgery or an anaesthetic or are going into hospital.

Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects. Go to your doctor regularly for a check-up.

Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.

Things you must not do

Do not:

  • Give this medicine to anyone else, even if their symptoms seem similar to yours.
  • Take your medicine to treat any other condition unless your doctor tells you to.
  • Stop taking your medicine, or change the dosage, without first checking with your doctor.

Things to be careful of

Make sure you drink enough water during any exercise and during hot weather when you are taking furosemide (frusemide), especially if you sweat a lot. If you do not drink enough water while taking furosemide (frusemide), you may feel faint or light-headed or sick. This is because your blood pressure is dropping suddenly and you are dehydrating. If you continue to feel unwell, tell your doctor.

If you feel light-headed, dizzy or faint, get up slowly when getting out of bed or standing up. You may feel light-headed or dizzy when you begin to take furosemide (frusemide). This is because your blood pressure is falling suddenly. Standing up slowly, especially when you get up from beds or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.

Be careful driving or operating machinery until you know how furosemide (frusemide) affects you. Diuretic medicines may cause dizziness or light-headedness in some people. Make sure you know how you react to your medicine before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or lightheaded.

If this occurs do not drive.

If you drink alcohol or take strong painkillers, dizziness or light-headedness may be worse.

The effects of alcohol could be made worse while taking furosemide (frusemide). It is not recommended that you drink alcohol while taking furosemide (frusemide).

If you are taking furosemide (frusemide) for a long period of time, you should check with your doctor to determine whether or not you should eat more potassium-containing foods or take potassium supplements. However, increasing the amount of potassium in your diet may not be necessary and could be harmful. Check with your doctor.

Furosemide (frusemide) may cause your skin to become more sensitive to the sun. If this happens you should take care to wear protective clothing including a hat and sun block when you are outside.

Other side effects not listed above may occur in some people.
