What is LANOXIN
LANOXIN belongs to a group of medicines known as cardiac glycosides. They work by slowing down the rate while increasing the force of your heart when it beats.
It is used to treat certain heart problems, such as:
Chronic Heart failure
Heart failure is when your heart can’t pump strongly enough to supply blood needed through out the whole body. It is not the same as a heart attack and does not mean that your heart stops.
Certain type of irregular heart beats
Irregular heart rhythms caused by an electrical problem in the upper chamber of your heart. They cause your heart to beat too fast or in an uneven way.
Ask your doctor if you have any questions about why LANOXIN has been prescribed for you. Your doctor may have prescribed LANOXIN for another reason.
There is no evidence that LANOXIN is addictive.

How to take it
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
How much to take
Your doctor will tell you how much LANOXIN you will need to take each day. This depends on your condition and other factors such as your weight, age and other medicines you may be taking.
How to take it
Swallow LANOXIN tablets with a glass of water.
Accurately measure the dose with the calibrated dropper provided. Do not dilute. Using the dropper will make sure that you get the correct dose.
Do not change your dose of LANOXIN unless your doctor tells you to do so.
After you begin taking LANOXIN, your doctor may sometimes check its level in your blood. This will help your doctor find out if your dose needs to be changed.
When to take it
Take LANOXIN at same time each day. Taking LANOXIN at the same time each day will have the best effect. It will also help you remember when to take it.
It does not matter if you take LANOXIN before or after food.
If you forget to take it
Take it as soon as you remember. However, if it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Do not take a double dose to make up for the dose 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.
How long to take it
Continue taking LANOXIN for as long as your doctor tells you.
LANOXIN helps control your condition, but does not cure it. Therefore, you must take LANOXIN every day.
If you take too much (overdose)
Immediately telephone your doctor or the 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 LANOXIN. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Symptoms of an overdose to LANOXIN include some of the side effects listed below.
Some early warning signs of overdose are loss of appetite, nausea, vomiting, diarrhoea, or extremely slow heart beat.
In infants and small children, the earliest signs of overdose are changes in the rate and rhythm of the heart beat.
Carers should be aware that children may not show symptoms as soon as adults.
While you are taking it
Things you must do
Tell your doctor immediately if you notice any side effects from LANOXIN.
Tell any other doctors, dentists and pharmacists who are treating you that you are taking LANOXIN.
Tell your doctor, dentist or pharmacist that you are taking LANOXIN before you start taking any medicines you buy from a pharmacy, health food shop or supermarket.
If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are taking LANOXIN.
If you become pregnant while taking LANOXIN, tell your doctor immediately.
If you need to have any medical tests while you are taking LANOXIN, tell your doctor. LANOXIN may affect the results of some tests.
Be sure to keep all of your doctor’s appointments so that your progress can be checked. Your doctor will check your progress and may want to take some blood tests from time to time. This helps to prevent unwanted side effects.
Things you must not do
Do not give LANOXIN to anyone else, even if their symptoms seem similar or they have the same condition as you.
Do not take LANOXIN to treat any other complaints unless your doctor tells you to.
Do not stop taking LANOXIN, or change the dose even if you are feeling better, without checking with your doctor.
Things to be careful of
Be careful driving or operating machinery until you know how LANOXIN affects you. LANOXIN may cause dizziness, blurred vision, and faintness in some patients. Make sure you know how you react to LANOXIN, before you drive a car, operate machinery, or do anything else that could be dangerous if this happens.
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.
If any of the following happen, tell your doctor or pharmacist immediately:
- nausea or vomiting, loss of appetite
- lower stomach pain
- slow or irregular heart beats (may be fast in children)
- unusual tiredness or extreme weakness
- general feeling of ‘unwellness’
- blurred vision or visual disturbances (e.g. coloured halos around objects i.e. yellow, green, or white)
- mental disturbances, such as confusion or feeling indifferent
- skin rash
- painful, swollen breasts, or breast enlargement in men
- bleeding or bruising more easily than normal.
These may be serious side effects. You may need urgent medical attention. Serious side effects are rare or are caused by a dose of LANOXIN that is too high for you.
Tell your doctor immediately if you have:
- chest pain
- shortness of breath or sweating.
These can be symptoms of a serious heart problem caused by new irregular heart beats of a different type to those caused by atrial fibrillation (which LANOXIN is often used to treat).
Your doctor may do regular checks on your blood levels of digoxin and body salts, as well as your kidney function to make sure LANOXIN is working safely for you.
Tell your doctor if you notice anything else that is making you feel unwell, even if it is not on this list. Other side effects not listed above may also occur in some people.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
After taking it
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.
Keep your LANOXIN tablets in the pack and the liquid in the bottle until it is time to take them. If you take the tablets or liquid out of the pack, they will not keep well.
Store LANOXIN-PG tablets in a cool, dry place away from light and where the temperature stays below 30ºC.
Store LANOXIN tablets and paediatric elixir in a cool, dry place away from light and where the temperature stays below 25ºC.
Do not store LANOXIN or any other medicine in the bathroom or near a sink. Do not leave it in the car on hot days or on windowsills. Heat and dampness can destroy some medicines.
If your doctor tells you to stop taking LANOXIN or the medicine has passed its expiry date, ask your pharmacist what to do with any that is left over.
