• Are allergic to digoxin, other cardiac glycosides or any of the other ingredients of this medicine (listed in section 6).
• Have serious heart problems, such as those with the conduction of the electrical impulses in the heart, especially if you have a history of Stokes-Adams attacks (abrupt, short-lived loss of consciousness caused by a sudden change in heart rate or rhythm).
• Have an irregular heart-beat caused by cardiac glycoside intoxication or conditions such as Wolff-Parkinson-White syndrome.
• Have obstructive cardiomyopathy (enlargement of the heart muscle).

Talk to your doctor, pharmacist or nurse before using this medicine:

• If you are taking this medicine, your doctor may ask you to have regular blood tests to determine the amount of digoxin in the blood. This may be useful in the case of patients with kidney disorders.
• If you develop digoxin toxicity, this can lead to various forms of heart rhythm disturbances, some of which resemble the rhythm disturbances for which the product was prescribed.
• If you have abnormal heart rhythm (heart block) and you are taking this medicine, contact your doctor immediately if you feel one or more of the following symptoms: fainting, short-lasting loss of consciousness, dizziness or light-headedness, fatigue (tiredness), shortness of breath, chest pain, irregular heart-beat or confusion.
• If you have a sinoatrial disorder (a disorder in the conduction of electrical impulses in the heart such as Sick Sinus Syndrome), in some patients with a sinoatrial disorder this medicine can cause a slow and/or irregular heart-beat. Sometimes this will cause tiredness, weakness and dizziness and when your heartbeat is very slow you may faint.
• If you have recently suffered a heart attack.
• When heart failure occurs along with the collection of an abnormal protein in the heart tissue (cardiac amyloidosis), an alternative therapy may be prescribed by the doctor.
• If you have myocarditis (inflammation of the heart muscle) this may cause vasoconstriction (narrowing of the blood vessels) on rare occasions. Your doctor may prescribe you a different medicine.
• If you have Beri-beri disease (caused by a vitamin B1 deficiency).
• If you have constrictive pericarditis (inflammation of the sac which contains the heart).
• If you are taking diuretics (drugs which promote urine production and help reduce the amount of water in your body) with or without an ACE inhibitor (mainly used to treat high blood pressure), your doctor will prescribe a lower dose of Digoxin injection. Do not stop taking Digoxin injection without talking to your doctor.
• If you have a heart test called an ECG (electrocardiogram), tell the person doing the test that you are taking Digoxin injection as it can affect the meaning of the results.
• If you have severe respiratory (lung) disease (as you may have an increased sensitivity to Digoxin injection)
• If you have low levels of oxygen reaching certain parts of your body, low levels of potassium, abnormally low levels of magnesium or increased levels of calcium in your blood
• If you have thyroid disease (such as an under-active or over-active thyroid) as you might require changes in the dose of this medicine
• If you have malabsorption syndrome (you cannot absorb minerals from your food properly) or if you have ever had gastro-intestinal reconstruction surgery
• If you will receive electric shock treatment to correct an abnormal heart-beat.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Taking several medicines can sometimes have harmful consequences or lead to unwanted interactions.

Pregnancy

Your doctor will prescribe this medicine with caution during pregnancy.

You may require a higher dose of this medicine if you are pregnant.

This medicine could be given to the mother to treat abnormally high heart rate and congestive heart failure in the unborn child.

Side effects of Digoxin injection treatment affecting the mother may also affect the unborn child.

Breastfeeding

This medicine is excreted in breast milk, but in very small amounts. Therefore, this medicine can be used by women who are breast-feeding.

Fertility

There is no information available on the effect of Digoxin injection on fertility.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Since dizziness and blurred or yellow vision have been reported, you should exercise caution before driving a vehicle, using machinery or participating in dangerous activities.

Ethanol:

• Digoxin injection contains 166 mg of alcohol (ethanol) in each 2ml ampoule, which is equivalent to 83 mg/ml (8% w/v).

The amount in each ampoule of this medicine is equivalent to less than 5 ml beer or 2 ml wine. The small amount of alcohol in this medicine will not have any noticeable effects.

Sodium:

• This medicine contains less than 1 mmol sodium (23 mg) per dose, that is to say, essentially “sodium free”.

As Digoxin injection is administered under the supervision of a doctor, it is unlikely that you will be given more or less than is necessary. However, if you have any concerns about the dose of your medicine discuss them with your doctor.

The main symptoms of digoxin toxicity are heart rhythm disturbances and gastrointestinal symptoms which may happen before heart rhythm disturbances. Gastrointestinal symptoms include loss of appetite, nausea and vomiting. Other symptoms of digoxin toxicity include dizziness, fatigue, a general feeling of being unwell and various neurological disturbances including visual disturbances (more yellow-green than usual). The neurological and visual symptoms may persist even after other signs of toxicity have been resolved. In chronic toxicity, non-heart related symptoms, such as weakness and a general feeling of being unwell, may be the main symptoms.

Do not take a double dose to make up for the forgotten dose.

Your doctor will tell you how long you should take Digoxin injection. Do not stop your treatment early without consulting your doctor.

If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in this leaflet. You can also report side effects directly via the Yellow Card Scheme: Website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store
