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

All medicines have risks and benefits. Your doctor or pharmacist has weighed the risks of you taking Rythmodan 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 Rythmodan is used for
Rythmodan belongs to a group of medications called antiarrhythmics. This means it acts to correct irregular heartbeats to a normal rhythm and to slow an overactive heart. This allows the heart to work more efficiently.

Rythmodan is used to treat and prevent ventricular arrhythmias (irregular heartbeat).

Ask your doctor if you have any questions about why Rythmodan has been prescribed for you. Your doctor may have prescribed Rythmodan for another reason. This medicine is available only with a doctor's prescription.

Before you take Rythmodan
When you must not take it
Do not take Rythmodan if you have an allergy to Rythmodan or any of the ingredients listed at the end of this leaflet. Some symptoms of an allergic reaction may include skin rash, itching, shortness of breath or swelling of the face, lips or tongue, which may cause difficulty in swallowing or breathing.

Do not give Rythmodan to a child or adolescent. Rythmodan is not recommended for use during pregnancy, unless you and your doctor or pharmacist have discussed the risks and benefits involved.

Do not take Rythmodan if you are breast-feeding or plan to
breast-feed. Rythmodan passes into breast milk and therefore there is a possibility that the breast-fed baby may be affected.

Rythmodan is not recommended for use in children.

Do not take Rythmodan after the expiry date (EXP) printed on the pack. If you take this medicine after the expiry date has passed, it may not work as well.

Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop. Some medicines and Rythmodan may interfere with each other. These include:

Other antiarrhythmics used to treat heart conditions such as beta-blockers, amiodarone and calcium channel blockers

These medicines may be affected by Rythmodan, or may affect how well it works. You may need different amounts of your medicine, or you may need to take different medicines. Your doctor or pharmacist will advise you.

Your doctor and pharmacist may have more information on medicines to be careful with or avoid while taking Rythmodan.

How to take it
How much to take
The dose of Rythmodan may be different for each person. Your doctor will decide the right dose for you.

How to take it
Swallow Rythmodan whole with plenty of fluid.

The daily dose of Rythmodan is usually taken in three equally divided doses.

When to take it
Take Rythmodan at about the same time each day. Taking your capsules at the same time each day will have the best effect. It will also help you
remember when to take your medicine.

It does not matter if you take Rythmodan before or after food.

This medicine works best when there is a constant amount in the blood. To help keep the amount constant it is best to take the doses at evenly spaced intervals day and night.

How long to take it
Rythmodan helps control your condition, but does not cure it. Therefore you must take Rythmodan every day. Continue taking the capsules for as long as your doctor or pharmacist tells you.

Do not stop taking your capsules because you are feeling better.

If you forget to take it
If it is almost time for your next dose (within 4 hours), 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 your medicine as you would normally.

Do not try to make up for a missed dose by taking more than one dose at a time. 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 to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)
Immediately telephone your doctor or pharmacist or the Poisons Information Centre (telephone 13 11 26 and in New Zealand telephone 0800 764766) or go to accident and emergency at your nearest hospital, if you think that you or anyone else may have taken too much Rythmodan. Do this
even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

If you take too much Rythmodan, you may feel cold and dizzy,
light-headed, weak or you may faint. You may also experience palpitations (your heart may feel like it "skips a beat") and have difficulty breathing. You may notice your pulse is rapid and weak.

While you are taking it
Things you must do
Tell all the doctors, dentists, and pharmacists who are treating you that you are taking Rythmodan.

If you are about to be started on any new medicine, tell your doctor, dentist or pharmacist that you are taking Rythmodan.

If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are taking Rythmodan. Rythmodan may cause hypoglycaemia (low blood sugar) in some people.

Patients with congestive heart disease or diabetes should be aware of the signs (see side effects) and if the signs appear eat or drink a food containing sugar and call your doctor.

Rythmodan may cause dryness of the mouth, nose and throat.

For temporary relief of mouth dryness melt bits of ice in your mouth. However, if dryness continues for more than 2 weeks, check with your medical doctor or dentist.

If you become pregnant while taking Rythmodan, tell your doctor or pharmacist.

Things you must not do
Do not give Rythmodan to anyone else, even if they have the same condition as you.

Do not take Rythmodan to treat any other complaints unless your doctor or pharmacist tells you to.

Do not stop taking Rythmodan, or lower the dosage, without checking with your doctor or pharmacist.

Things to be careful of
Be careful driving or operating machinery until you know how Rythmodan affects you.

It may cause dizziness,
light-headedness or fainting in some people. 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 light-headed. If this occurs do not drive.

The effects of alcohol could be made worse while taking Rythmodan. It is not recommended that you drink alcohol while taking Rythmodan.

Alcohol may make the low blood sugar (hypoglycaemia) effect worse and/or increase the possibility of dizziness or fainting.

Side effects
All medicines have some unwanted side effects. Sometimes they are serious, but most of the time they are not. Your doctor or pharmacist has weighed the risks of using this medicine against the benefits they expect it will have for you.

Do not be alarmed by this list of possible side effects. You may not experience any of them.

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Rythmodan.

Tell your doctor or pharmacist if you notice any of the following and they worry you:

Dry mouth, eyes, nose or throat
Bloating or stomach pain
Blurred vision
Constipation or diarrhoea
Frequent urge to urinate
Loss of appetite
Nausea and vomiting
Increased perspiration
Increased skin sensitivity to light
These are mild side effects of this medicine and usually short-lived.

Difficult urination
Redness, itching, swelling, blistering, itchy or raised skin rash, and/or hives
Chest pains
Dizziness, light-headedness or fainting
Fast or irregular heartbeat

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

After taking it
If you have any queries about any aspect of your medicine, or any questions regarding the information in this leaflet, discuss them with your doctor or pharmacist.

Keep your capsules in the pack until it is time to take them.

Keep your capsules in a cool dry place where the temperature stays below 30 °C. Do not store it or any other medicine in the bathroom or near a sink.

Do not leave it in a car or on a windowsill. Heat and dampness can destroy some medicines.

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.

If your doctor or pharmacist tells you to stop taking Rythmodan or the capsules have passed their expiry date, ask your pharmacist what to do with any that are left over.

Return any unused medicine to your pharmacist.
