1. WHAT LANOXIN IS AND WHAT IT IS USED FOI
Lanoxin contains a medicine called digoxin. This belongs to a group of medicines called '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:
• heart failure
This is when your heart muscle can't pump strongly enough to supply blood around your whole body. It is not the same as a heart attack and does not mean that your heart stops.
• certain types of irregular heart beats
These include 'atrial flutter' or 'fibrillation'. They are caused by problems in the way the upper chambers of your heart send electrical signals. They cause your heart to beat too fast or in an uneven way.
2. BEFORE YOU TAKE LANOXIN
Do not take Lanoxin if:
• you are allergic (hypersensitive) to digoxin, digitoxin or any of the other ingredients of Lanoxin (listed in Section 6)
• you have been told that you have any of the following heart problems:
- 'Second degree' or 'intermittent complete heart block'
- Certain types of 'supraventricular arrhythmias'
- 'Ventricular tachycardia' or 'Ventricular fibrillation'
- 'Hypertrophic obstructive cardiomyopathy'
Your doctor should have checked your heart problem and decided that this medicine will help you. If you are not sure, talk to your doctor or pharmacist before taking Lanoxin.

Check with your doctor or pharmacist before using your medicine if:
• you have recently had a heart attack (myocardial infarction)
• you have been told that you have low potassium or magnesium levels in your blood hypomagnesaemia)

• you have a heart problem caused by a lack of vitamin B, known as 'Beri-Beri disease'

Your doctor will have decided how much Lanoxin is right for you:

The loading dose gets your Lanoxin levels up to the correct level quickly. You will either:
- take one large single dose and then begin your maintenance dose or

- The doctor will decide this, depending on your child's response to Lanoxin.
- It is usually a 1/5 (fifth) or a 1/4 (quarter) of the loading dose, to be taken daily.
If you use more Lanoxin than you should
If you take too much or if somebody else takes your medicine by mistake, go to the hospital immediately. You may get any of the side effects and symptoms listed in Section 4, but these can be serious.
If you forget to use Lanoxin
• If you forget to take a dose, take it as soon as you remember. However, if it is almost time for the next dose, skip the missed dose.
