About amiodarone

Type of medicineAnti-arrhythmic
Used forArrhythmias (irregular heart beats)
Also calledCordarone X®, Amyben®
Available asTablets and injection

Amiodarone is used to treat heart arrhythmias. An arrhythmia is an irregularity in the heartbeat, which causes the heart to miss a beat, beat irregularly, or beat at the wrong speed.

Amiodarone works by correcting the rhythm of the heart and by slowing a heart that is beating too fast.

Before taking amiodarone

Before taking amiodarone make sure your doctor or pharmacist knows:

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you suffer from liver or thyroid problems.
  • If you have heart block or heart failure.
  • If you suffer from porphyria (a rare blood disorder).
  • If you are allergic to iodine.
  • If you are taking other medicines, including those available to buy without a prescription, herbal or complementary medicines.
  • If you have ever had an allergic reaction to this or any other medicine.

How to take amiodarone

  • Before beginning treatment, read the manufacturer's printed information leaflet.
  • Take your medication exactly as directed by your doctor. Swallow amiodarone tablets with a drink of water.
  • The usual dose of amiodarone is 200mg three times a day for the first week, then 200mg twice a day for the second week, and reduced to 200mg daily from the third week. It is very important that you follow the directions given to you by your doctor. If you are not sure what dose to take, ask your doctor or pharmacist for advice.
  • Do not stop taking amiodarone without speaking to your doctor first, even if you begin to feel better. Stopping treatment may cause your symptoms to return.
  • Try to take amiodarone at the same times each day to avoid missing any doses.
  • If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue taking amiodarone at the usual times. Do not take two doses at the same time to make up.

Getting the most from your treatment

  • If you are having any treatment like an operation or dental treatment, tell the person carrying out the treatment that you are taking amiodarone.
  • Keep your regular doctor's appointment so your progress can be monitored. You will need to have regular blood tests while you are taking amiodarone.
  • Avoid drinking grapefruit juice while you are taking amiodarone as it can increase the level of amiodarone in your blood.
  • If you buy any medicines, check with a pharmacist that they are safe to take with your other medicines.
