This prescription item requires a pre approved authority from the Government in order to get this item at the quoted price. Authority prescriptions need to be applied for by the doctor writing the script and can include reasons such as increased quantities due to dosage, increased repeats, use for a pre determined specified use, or the nature of the medication itself requiring specialist interaction. In the event that an authority is not granted on the script, the price will revert to the private price quoted for that item


This item contains more than one pack of a prescription product. Before this can be dispensed the doctor has to give approval. The prescription must be written for the total quantity or the prescription must be endorsed by your doctor "Regulation 24" otherwise we will be unable to dispense the increased amount. If you proceed with the order without approval, we will only send out one pack at the single pack price and refund the difference. Eg If your prescription is written out for 30 Tablets with 5 repeats and it does not have “Regulation 24 “ written on the script, the ONLY quantity we can dispense is 30 at one time. Further dispensing of this product could only occur after an appropriate length of time - usually 21 days but depends on dosage. In this example if you would like to obtain 180 Tablets then the doctor must endorse the prescription “Regulation 24” or the quantity must be written out for 180 and not 30. NB Conditions apply on the writing of a Regulation 24 prescription. Ask your doctor or pharmacist for details.

We can no longer accept signed authority forms from your doctor as permission to dispense more than one pack. Please contact our pharmacist for more information.

If you order this item as Private, NO PBS stickers will be issued. Once any prescription order has been sent the product cannot be returned for a refund even if your doctor changes your medication or you have an adverse reaction.

General Information

Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about Duro-K.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

The information in this leaflet was last updated on the date listed on the final page. Some more recent information on the medicine may be available. You should ensure that you speak to your pharmacist or doctor to obtain the most up to date information on the medicine. You can also download the most up to date leaflet from www.novartis.com.au.

Those updates may contain important information about the medicine and its use of which you should be aware.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking Duro-K against the benefits they expect it will have for you. If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What Duro-K is used for Duro-K tablets are used to provide extra potassium:
for people who do not have enough potassium in their regular diet
for people who have lost too much potassium from their bodies because of illness or treatment with certain medicines.

Potassium is essential for life and health. Natural sources of potassium are found in bananas, avocados, raisins, cantaloupe melons, dried dates, apricots and dark-green leafy vegetables. Too much potassium can also be harmful. It is important to take Duro-K only as prescribed by your doctor. Duro-K dosage may need to be adjusted if your diet is rich in natural sources of potassium. However, never change your dosage without medical advice. Ask your doctor if you have any questions about why Duro-K has been prescribed for you.

Your doctor may have prescribed it for another purpose. Duro-K is only suitable for adults. Duro-K should not be given to children as there is not enough information on its use in that age group. This medicine is not addictive. Before you take Duro-K When you must not take it

Do not take Duro-K if you have an allergy to any of the ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin. Do not take Duro-K if you already have a high level of potassium in your body. This can happen in the following medical conditions:
severe kidney disease
Addison's disease (underactive adrenal glands) that has not been treated
dehydration, severe burns or other serious injury where large amounts of body fluids have been lost
metabolic acidosis

If you are not sure whether any of the above conditions apply to you, your doctor can give you more information.

Do not take Duro-K if you have problems with your digestion where passage of food or medicine is slow or blocked.

If you take Duro-K, it may not pass through your digestive system properly and could cause an ulcer. Do not take Duro-K after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.

In that case, return it to your pharmacist. If you are not sure whether you should start taking Duro-K, talk to your doctor or pharmacist.

Before you start to take it

Tell your doctor if you are allergic to any other medicines, foods, dyes or preservatives.

Your doctor will want to know if you are prone to allergies. Tell your doctor if you have any of the following medical conditions:
a stomach ulcer now or in the past
kidney problems
heart problems
frequent or severe diarrhoea

Your doctor may want to take special precautions if you have any of the above conditions.

Tell your doctor if you are pregnant or intend to become pregnant or if you are breast feeding.

During pregnancy your digestion tends to slow down. This means that Duro-K tablets may take longer than usual to be digested and can cause increased side effects. Your doctor can discuss with you the risks and benefits of taking Duro-K during pregnancy. Tell your doctor if:
you are on a low-salt, low-sugar or any other special diet
you eat licorice regularly
you use salt substitutes or drink low-salt milk.

Any of the above can affect the amount of potassium in your body and could change the amount of Duro-K you will need to take. Taking other medicines

Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.

Some medicines and Duro-K may interfere with each other. These include:
some diuretic medicines (also called water or fluid tablets)
medicines used to treat Parkinson's disease
some medicines used to treat stomach cramps
some medicines used to prevent or treat travel sickness
some medicines used to treat urinary incontinence
large doses of laxatives

These medicines may be affected by Duro-K or they may affect how well it works. You may need to take different amounts of your medicines or you may need to take different medicines.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking Duro-K. If you have not told your doctor about any of these things, tell him/her before you start taking Duro-K.

How to take Duro-K Follow all directions given to you by your doctor and pharmacist carefully.

They may differ from the information contained in this leaflet. If you do not understand the instructions on the label, ask your doctor or pharmacist for help.

How much to take

The amount of Duro-K you need will depend on the level of potassium in your body. You will usually need from 2 to 6 tablets each day. It may be necessary to take more Duro-K tablets per day but never increase the dose without your doctor's advice.

If you are also taking a diuretic (water or fluid tablet), you may only need 1 or 2 tablets of Duro-K each day. When to take it

The tablets are usually taken in 2 or 3 doses during the day.

How to take it

Swallow the tablets whole with a full glass of water or other liquid. Do not crush, chew or suck the tablets.

Take the tablets during meals to lessen the chance of stomach upset.

If you have problems swallowing the tablets or they seem to stick in your throat, check with your doctor.

This could cause irritation that might lead to ulcers.

If you forget to take it

If you miss a dose of Duro-K and you remember within 2 hours, take the missed dose right away. Then continue with your regular schedule.

However, if you do not remember until later, skip the dose you missed and take the next dose according to your regular schedule.

Do not take a double dose to make up for the one that you missed.

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

If you are not sure what to do, ask your doctor or pharmacist.

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

How long to take it

Continue taking Duro-K for as long as your doctor tells you.

Your doctor will check the amount of potassium in your body from time to time to make sure the medicine is working and will discuss with you how long your treatment should continue.

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 that you or anyone else may have taken too much Duro-K. Do this even if there are no signs of discomfort or poisoning.

Keep the telephone numbers for these places handy.

Some of the symptoms of an overdose may include difficulty breathing, a drop in blood pressure, fast or irregular heartbeat, numbness or seizures (fits). While you are taking Duro-K Things you must do

If you become pregnant while taking Duro-K, tell your doctor immediately.

Your doctor can discuss with you the risks of taking it while you are pregnant. Be sure to keep all of your doctor's appointments so that your progress can be checked.

Your doctor may want to do blood tests from time to time to make sure your potassium level is right. If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Duro-K.

Tell any other doctor, dentist or pharmacist who treats you that you are taking Duro-K.

Things you must not do

Do not take Duro-K to treat any other complaints unless your doctor tells you to.

Do not give Duro-K to children.

Do not give this medicine to anyone else, even if their symptoms seem similar to yours or they have the same condition as you do.

Side effects Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Duro-K.

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. Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor if you notice any of the following side effects and they worry you:
nausea (feeling sick) or vomiting
wind or pain in the abdomen

Duro-K can occasionally cause stomach upset, especially if your digestion is slow.

Stop taking Duro-K and tell your doctor immediately or go to Accident and Emergency at your nearest hospital if you notice any of the following:
severe nausea or vomiting
vomiting blood or material that looks like coffee grounds
severe wind or pain in the stomach or abdomen
diarrhoea with black or blood-stained bowel motions

The above side effects may be serious. You may need urgent medical attention.

Tell your doctor if you notice anything else that is making you feel unwell.

Other side effects not listed above may happen in some people. Do not be alarmed if you notice what looks like whole tablets in your bowel motions.

Duro-K tablets contain potassium in a special wax core covered with a sugar coating. The sugar coat has dissolved and the potassium has been absorbed into your body. The remaining wax core is "waste" material that passes out in the bowel motions.

After using Duro-K Storage
Keep your tablets in the container until it is time to take them.
Store the tablets in a cool dry place away from direct sunlight.
Do not store Duro-K or any other medicine in the bathroom or near a sink.
Do not leave the tablets in the car or on window sills.

Heat and dampness can destroy some medicines. Duro-K will keep well if it is cool and dry. Keep the tablets where children cannot reach them.

A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines. Disposal
If your doctor tells you to stop taking Duro-K or it has passed its expiry date, ask your pharmacist what to do with any medicine you have left over.
