50 mg / ml injection solution 
amiodarone hydrochloride

What Cordarone is and what it is used for

This product is only used in hospitals. Cordarone is an antiarrhythmic, which lowers the heart’s electrical irritability while counteracting rapid and irregular heartbeat ( arrhythmias ).

Cordarone is used to treat severe heart rhythm disorders and when other medicines have not been effective or can be used.

The amiodarone contained in Cordarone may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before taking Cordarone

Do not use Cordarone

  • if you are allergic to amiodarone, iodine, or any of the other ingredients of this medicine (listed in section 6)
  • if you have a slow heartbeat (if you do not have a pacemaker)
  • if you have certain other types of heart disorders (if you do not have a pacemaker)
  • if you have disorders of thyroid function (metabolism)
  • if you have insufficient blood circulation or very low blood pressure
  • if you are breast-feeding
  • if you are being treated with certain medicines, see section “Other medicines and Cordarone”
  • Intravenous injection should not be given if the patient has low blood pressure, severe respiratory failure, heart muscle disease, or heart failure. The intravenous injection may aggravate these diseases.
  • Due to the presence of benzyl alcohol, Cordarone solution for injection should not be given to newborns, infants, or children up to 3 years of age.

The above does not apply to use in advanced cardiopulmonary resuscitation in case of cardiac arrest due to ventricular fibrillation ( ventricular fibrillation ) which does not respond to cardiac initiation therapy (defibrillation).

Warnings and cautions

Talk to your doctor or pharmacist before taking Cordarone:

  • if you have low blood pressure, severe breathing, or heart failure
  • if you are taking medicines containing sofosbuvir for the treatment of hepatitis C, as it may cause your heart rate to drop to a life-threatening level. Your doctor may consider alternative treatments. If you need treatment with amiodarone and sofosbuvir, extracardiac monitoring may be necessary.

If you are on a waiting list for a heart transplant, your doctor may change your treatment. This is because treatment with amiodarone before heart transplantation has been shown to increase the risk of a life-threatening complication where the transplanted heart stops functioning properly within the first 24 hours after transplantation (primary graft dysfunction).

Tell your doctor immediately if you are taking medicines containing sofosbuvir for the treatment of hepatitis C and you experience during treatment:

  • slow or irregular heartbeat, or problems with heart rhythm
  • shortness of breath or worsening of pre-existing shortness of breath
  • chest pain
  • dizziness 
  • palpitation
  • that you almost faint, or faint

Contact a doctor immediately if you receive Cordarone during treatment:

  • dry cough and shortness of breath may be signs of side effects from the lungs.
  • severe skin reactions
  • impaired vision.

See section 4 Possible side effects for further information.


There are only limited data on the safety and efficacy in children.

Other medicines and Cordarone

  • agents against protozoa (pentamidine)
  • drugs for opioid dependence and severe pain conditions ( methadone )
  • anti-malarial drugs (mefloquine)

The effect of treatment with Cordarone may be affected or serious side effects may be exacerbated if Cordarone is taken at the same time as certain medicines, eg:

  • beta-blockers, flecainide, digoxin, verapamil, diltiazem, nisoldipine (used to treat heart diseases such as high blood pressure and heart failure )

  • triazolam (sedatives and sleeping pills)
  • fluoroquinolone is, amphotericin B ( antibiotics )
  • intestinal irritants laxatives

  • sofosbuvir (medicine for hepatitis C)

Before any surgery, it is important that your anesthesiologist knows that you are using Cordarone.

Cordarone is broken down slowly and therefore remains in the body long after the end of treatment (individually, but up to several months). This is especially true when long-term treatment with Cordarone tablets, but also with Cordarone injection. It can therefore affect other medicines even after your Cordarone treatment has stopped. Consult a physician in case of uncertainty.

Pregnancy and breastfeeding

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.

There is a risk that the fetus is affected. Therefore, do not use Cordarone during pregnancy unless you have been prescribed by a doctor.

It is possible that a breastfed baby may be affected. Therefore, do not use Cordarone while breast-feeding.

Driving and using machines

Cordarone is unlikely to impair your ability to drive or use machines.

Cordarone contains benzyl alcohol

Cordarone contains benzyl alcohol as a preservative (20 mg/ml). May cause poisoning or allergic reactions in infants and children under 3 years of age.

3. How to use Cordarone

Cordarone solution for injection is used in hospitals as an intravenous infusion or injection. Dosage one is determined and adjusted individually by the doctor.

The usual dose is 5 mg/kg body weight. For further information on dosing, see section: “The following information is intended for healthcare professionals only” at the end of this leaflet.

If you use more Cordarone than you should 

Your doctor or healthcare professional will give you Cordarone and it is unlikely that you will receive too much of the medicine. If you suspect you have been given too much, tell your healthcare provider immediately.

If you have any further questions on the use of this product, ask your doctor, pharmacist, or nurse.
