6. Further information
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.
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.
