Amiodarone is used to treat heart arrhythmias. An arrhythmia is an irregularity in your heartbeat which causes your heart to miss a beat, beat irregularly or beat at the wrong speed. Amiodarone is particularly helpful when other medicines used for the treatment of arrhythmias are unsuitable for some reason.

Amiodarone works by correcting the rhythm of your heart and by slowing your heart if it is beating too fast. It will be prescribed for you by a heart specialist doctor.

Before taking amiodarone

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking amiodarone it is important that your doctor knows:

  • If you have any heart problems other than your abnormal heart rhythm. In particular, you should let your doctor know if you have been diagnosed with heart failure.

  • If you have problems with your thyroid gland.

  • If you know you have low amounts of potassium in your blood.

  • Si tienes un trastorno sanguíneo hereditario raro llamado porfiria.

  • Si estás embarazada o amamantando.

  • Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

  • If you have ever had an allergic reaction to a medicine. It is particularly important that you tell your doctor if you know you are allergic to iodine.

How to take amiodarone

  • Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about amiodarone and will provide you with a full list of the side-effects which you may experience from taking it.

  • Your doctor will tell you what the right dose of amiodarone is for you, and this dose will be printed on the label of the pack of tablets to remind you about what the doctor said to you. It is usual to take 200 mg three times a day for the first week, then 200 mg twice a day for the second week. Your dose may then be reduced to 200 mg each day from the third week. It is very important that you take amiodarone exactly as your doctor tells you to. If you are not sure what dose to take, ask your doctor or pharmacist for advice.

  • Try to take your doses of amiodarone at the same times each day, as this will help you to remember to take them regularly. You can take amiodarone either before or after meals.

  • Si olvida tomar una dosis, tómela tan pronto como lo recuerde (a menos que esté cerca la hora de su próxima dosis, en cuyo caso omita la dosis olvidada). No tome dos dosis juntas para compensar una dosis olvidada.

Obteniendo el máximo de tu tratamiento

  • Try to keep your regular appointments with your doctor. This is so your doctor can check your heart rhythm and monitor your progress. Your doctor will also want to do some blood tests while you are on amiodarone to check your liver and thyroid function.

  • Your doctor is likely to recommend that you have an eyesight test each year. This is because you may develop deposits in your eyes. This is not likely to affect your vision, but if you are a driver you may find that you are dazzled by headlights if you drive at night.

  • Taking amiodarone is likely to cause your skin to become more sensitive to sunlight than normal. Whenever you go outside on bright days (even if it is cloudy, or if it is only for a relatively short period of time), use a sunscreen that has a high sun protection factor and also protects your skin against UVA light. Do not use sunbeds.

  • Do not drink grapefruit juice while you are on amiodarone. This is because a chemical in grapefruit juice can increase the amount of amiodarone in your bloodstream. This makes side-effects more likely.

  • Treatment with amiodarone is usually long-term unless you experience an adverse effect. You should continue to take it unless you are advised otherwise by your doctor.

  • If you are having an operation or any medical/dental treatment, remember to tell the person carrying out the treatment that you are taking amiodarone. It can interfere with some anaesthetics and increase the risk of side-effects.

  • If you buy any medicines 'over the counter', always check with a pharmacist that they are suitable for you to take alongside your other medicines. Many medicines can interfere with the way amiodarone works.

Can amiodarone cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with amiodarone. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Importante: there have been some reports of amiodarone causing damage to the liver (hepatotoxicity) and damage to the lungs (pneumonitis). The symptoms of liver damage are yellowing of the skin or the whites of the eyes, and feeling very tired or sick (nausea). The symptoms of lung damage are a persistent cough and breathlessness. If you experience any of these symptoms, you should contact your doctor for advice straightaway.
