1.        What Lanoxin PG Elixir is and what it is used for 


Lanoxin contains the active substance digoxin, which belongs to a group of medicines called cardiac glycosides. It is used to treat arrhythmias and heart failure. An arrhythmia is an irregularity in the heart-beat, which causes the heart to skip a beat, beat irregularly or beat at the wrong speed. This medicine works by correcting irregular heartbeats to a normal rhythm and strengthens the force of the heart-beat, which is why it is useful in heart failure.


2.        What you need to know before you use Lanoxin PG Elixir


Do not use Lanoxin PG Elixir if you:


-         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).


Warnings and precautions


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 Lanoxin 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 Lanoxin. Do not stop taking Lanoxin 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 Lanoxin as it can affect the meaning of the results.

-         If you have severe respiratory (lung) disease (as you may have an increased sensitivity to Lanoxin).

-         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.

Taking this medicine

You usually take this medicine in two stages:


·        Stage 1 - loading dose

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

-         take a smaller dose each day for a week and then begin your maintenance dose


·        Stage 2 - maintenance dose

After your loading dose you will take a much smaller dose every day, until your doctor tells you to stop.



Adults and children over 10 years

Ÿ loading dose

-         Usually between 0.75 and 1.5 mg as a single dose

-         For some patients, this may be given in divided doses 6 hours apart

-         Alternatively, between 0.25 and 0.75 mg may be given each day for a week

Ÿ maintenance dose

-         Your doctor will decide this, depending on your response to this medicine

-         It is usually between 0.125 and 0.25 mg daily


Children under 10 years

Ÿ loading dose

-         This is worked out using your child’s weight

-         Usually between 0.025 and 0.045 mg per kg of body weight

-         This should be given in divided doses between 4 and 8 hours apart

Ÿ maintenance dose

-         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



Elderly people may be given a lower dose than the usual adult dose. This is because older people may have reduced kidney function. Your doctor will check the levels of Lanoxin in your blood and may change your dose if necessary.


If you use more Lanoxin PG Elixir than you should


If you have taken too much Lanoxin PG Elixir or a child has taken the medicine by accident, contact your doctor, hospital or poison centre to evaluate the risks and get more information.


The main symptoms of Lanoxin 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 Lanoxin 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.


If you forget to use Lanoxin PG Elixir

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


If you stop using Lanoxin PG Elixir

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