What this medicine is used for

APO-Eplerenone tablets are used to:

  • treat heart failure in patients who have experienced a heart attack.
  • reduce the risk of death or need for hospitalisations due to heart failure in patients with chronic heart failure.

A heart attack occurs when one of the major blood vessels supplying blood to your heart becomes blocked. This means that your heart cannot receive the oxygen it needs and becomes damaged. This may lead to further problems, such as heart failure, irregular heart rhythms and blood clots.

Heart failure means that the heart muscle is weak and cannot pump blood strongly enough to supply all the blood needed throughout the body. Heart failure is not the same as heart attack, and may start off with mild or no symptoms, but as the condition progresses, patients may feel short of breath or may get tired easily after light physical activity such as walking. Some patients may wake up short of breath at night or have to prop their heads up during sleep to avoid this problem. Fluid may collect in different parts of the body, often first noticed as swollen ankles and feet.

How it works

Eplerenone belongs to a group of medicines called ‘selective aldosterone blockers’ that stop the action of aldosterone, a substance made by your body.

Aldosterone is important for regulating blood pressure and is one of the factors involved in heart function. Sometimes aldosterone can cause changes in our body that lead to heart failure. Eplerenone works by blocking the action of aldosterone and slowing the progression of heart failure by reducing heart damage.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is available only with a doctor’s prescription.

How long to take it

Continue taking your medicine for as long as your doctor tells you.

This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.

Make sure you have enough to last over weekends and holidays.

If you forget to take it

If it is less than 12 hours before your next dose, skip the dose you missed and take your next dose when you are meant to.

Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.

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.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

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 the nearest hospital, if you think that you or anyone else may have taken too much of this medicine.Do this even if there are no signs of discomfort or poisoning.

While you are taking this medicine

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking eplerenone.

Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.

If you become pregnant while taking this medicine, tell your doctor immediately.

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.

If you are about to have any blood tests, tell your doctor that you are taking this medicine.

Tell your doctor if you feel lightheaded or dizzy after taking your first dose of this medicine, or when your dose is increased.

Make sure you drink enough water during exercise and hot weather when you are taking this medicine, especially if you sweat a lot. If you do not drink enough water while taking eplerenone, you may feel faint, light-headed or sick. This is because your blood pressure is dropping suddenly. If you continue to feel unwell, tell your doctor.

Tell your doctor if you have excess vomiting or diarrhoea while taking eplerenone. You may lose too much water and salt and your blood pressure may drop too much.

Tell your doctor if you are taking salt tablets. Taking this medicine together with salt tablets can lead to serious side effects.

Keep all of your doctor’s appointments so that your progress can be checked. Your doctor may occasionally do a blood test to check your potassium levels and see how your kidneys are working. Your doctor may adjust your dose of this medicine depending on the potassium levels in your blood.

Things you must not do

Do not take this medicine to treat any other complaints unless your doctor tells you to.

Do not give your medicine to anyone else, even if they have the same condition as you.

Do not stop taking your medicine or lower the dosage without checking with your doctor. If you stop taking it suddenly, your condition may worsen or you may have unwanted side effects.

Things to be careful of

Be careful driving or operating machinery until you know how this medicine affects you. This medicine may cause dizziness and feeling faint in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.

If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking this medicine. This medicine helps most people with heart failure, but it may have unwanted side effects in some people. All medicines can have side effects.
