What Urex is used for
The active ingredient in Urex is called frusemide which belongs to a group of medicines called diuretics. Diuretics are used to help the kidneys remove excess fluid from the body.
Urex is used to treat a number of medical conditions, including:
- oedema (swelling of the body due to excess fluid).
This problem can also occur in cases of heart, liver or kidney disease.
- hypertension (high blood pressure).
This can occur by itself or in severe heart, liver or kidney disease.
Ask your doctor if you have any questions about why Urex has been prescribed for you. Your doctor may have prescribed it for another purpose.
This medicine is available only with a doctor’s prescription.

How to take it
How much to take
The dose of Urex may be different for each person and their medical condition. Your doctor will decide the right dose for you.
The recommended doses for:
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 per day up to a maximum of 6 mg per kg per day or 40 mg per day.
Adults: 20 to 40 mg twice daily.
Only in unusual cases of reduced glomerular filtration (kidney disease) will a high dose using Urex Forte be required.
How to take it
Swallow the medicine with water.
If the dose is one-half tablet, there is a breakline on the tablet to help you divide it.
When to take it
This medicine should be taken either early in the day or in the morning and no later than 4 hours before retiring if a twice daily dose is required.
How long to take it
Continue taking Urex as long as your doctor recommends it.
If you forget to take it
If your dosing schedule is one dose a day, take the missed dose as soon as possible, but not later than 4 hours before bedtime. If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, 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 the dose that you missed.
If you are unsure about whether to take your next dose, speak to your doctor or pharmacist.
Do not try to make up for missed doses by taking more than one dose at a time. This may increase the chance of you getting an unwanted side effect.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much Urex. Do this even if there are no signs of discomfort or poisoning. Also report any other medicine or alcohol (including any barbiturates or narcotics) which has been taken. You may need urgent medical attention.
Symptoms of overdose may include weakness, dizziness, lethargy, nausea, vomiting, diarrhoea, anorexia, sweating, mental confusion, blurred vision, tingling in the arms or legs, restlessness, headache, tinnitus (ringing in the ears), cramping, constipation, and symptoms associated with electrolyte and fluid depletion and hypotension.
While you are taking it
Things you must do
Tell your doctor if, for any reason you have not taken your medicine exactly as directed or if you feel it is not helping your condition. Otherwise your doctor may think that it was not effective and change your treatment unnecessarily.
Tell all doctors, dentists and pharmacists who are treating you that you are taking Urex.
Immediately tell your doctor if you become pregnant while you are taking this medicine.
Visit your doctor regularly. Your doctor needs to check your progress and see whether you need to keep taking Urex.
Things you must not do
Do not take any other medicines while you are taking Urex without first telling your doctor.
Do not take Urex for a longer time than your doctor has prescribed.
Avoid prolonged exposure to direct sunlight.
Do not change your dose without first checking with your doctor.

Do not give this medicine to anyone else, even if their symptoms seem similar to yours.
Things to be careful of
Be careful drinking alcohol while taking Urex. If you drink alcohol, it could make some unwanted side effects of Urex worse.
Your doctor may suggest that you avoid alcohol completely or reduce the amount of alcohol you drink while you are taking this medicine.
Do not drive or operate machinery until you know how Urex affects you. Urex may cause dizziness in some people and therefore may affect alertness. Make sure you know how you react to it before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or have blurred vision.
Some people may experience side effects such as nausea, headache, dizziness, faintness or lightheadedness when standing up after resting, which may further affect the risk when using dangerous machinery.
Tell your doctor as soon as possible if you do not feel well while you are taking Urex. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

- yellowing of the skin or eyes
- tinnitus (ringing in the ears)
- muscle spasms
- severe or persistent headache

These are rare, serious side effects. Your doctor may lower the dose to help control serious side effects and decide on necessary tests to monitor any of the above problems.
Tell your doctor if you notice anything else that is making you feel unwell, even if you think the problems are not connected with this medicine and are not referred to in this leaflet. Other side effects not listed above may also occur in some people.
Do not be alarmed by this list of side effects. You may not experience any of them.
After taking it
Keep Urex in a cool dry place, protected from light, where the temperature stays below 30°C.
Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
Do not store it or any other medicines, in a bathroom or near a sink. Do not leave it in the car or on window sills. Heat and dampness can destroy some medicines.
If your doctor tells you to stop taking the tablets or they have passed their expiry date, ask your pharmacist what to do with any left over.
