1. What Amiodarone Injection is and what it is used for

Amiodarone Injection contains the active substance amiodarone hydrochloride. It belongs to a group of medicines called anti-arrhythmics.

It works by controlling the uneven beating of your heart (called arrhythmias).

Having the injection helps your heartbeat to return to normal.

Amiodarone Injection is normally only given in a hospital when a quick response is needed or when tablets cannot be given. Amiodarone Injection can be used to:

  • Treat uneven heartbeats where other medicines either have not worked or cannot be used
  • Treat an illness called Wolff-Parkinson-White Syndrome. This is where your heart beats unusually fast
  • Treat other types of fast or uneven heartbeats known as ‘atrial flutter’ or ‘atrial fibrillation.

2. What you need to know before you are given Amiodarone Injection

You must not be given Amiodarone Injection if:

  • You are allergic to amiodarone hydrochloride, iodine or to any of the other ingredients of this medicine (listed in section 6)
  • You have heart problems such as heart block, which can cause a slow heart rate (such as sino-atrial heart block, sinus bradycardia, high grade AV block, bifascicular or trifascicular block or sinus node disease) and you do not have a pacemaker
  • You have heart failure or weakness of the heart muscle (cardiomyopathy)
  • You have or have had thyroid problems. Your doctor will test your thyroid before giving you this medicine.
  • You have severe breathing problems.
  • You have very low blood pressure
  • You are taking other medicines that can make your heartbeat very quickly (these are listed below under the section ‘Taking other medicines’)
  • You are pregnant, think you may be pregnant or are breastfeeding (unless treatment is considered absolutely essential by your doctor)

Do not use this medicine if any of the above applies to you and talk to your doctor or nurse.

Amiodarone Injection must not be given to premature babies, neonates or a child up to 3 years old.

Warnings and precautions:

Talk to your doctor, pharmacist or nurse before you are given Amiodarone Injection if:

  • You have mild to moderate low blood pressure
  • You have a weak heart or heart failure
  • You have any problem with your thyroid gland. Your doctor will test your thyroid before giving you this medicine.
  • You have liver problems
  • You are receiving high dose oxygen therapy or have any other problems with your lungs including asthma
  • You are due to have an operation involving general anaesthesia
  • You are elderly
  • You currently take a medicine containing sofosbuvir for the treatment of hepatitis C as it may result in a life-threatening slowing of your heart beat. Your doctor may consider alternative treatments. If treatment with amiodarone and sofosbuvir is needed, you may require additional heart monitoring.

Taking other medicines

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

  • slow or irregular heartbeat or heart rhythm problems;
  • shortness of breath or worsening of existing shortness of breath;
  • chest pain;
  • light-headedness;
  • palpitations;
  • near-fainting or fainting.

The following medicine must not be taken with Amiodarone Injection as together they can cause a very severe fast heartbeat that can be fatal:

  • Medicines to treat irregular heart rhythms (anti-arrhythmics), such as quinidine, procainamide, disopyramide and sotalol
  • Antibiotics, such as erythromycin, moxifloxacin, cotrimoxazole and pentamidine
  • Medicines to treat mental illness (anti-psychotics), such as chlorpromazine, thioridazine, haloperidol, fluphenazine, amisulpride, sertindole and pimozide
  • Medicines to treat depression, such as lithium and tricyclic antidepressants, including doxepin, maprotiline and amitriptyline
  • Certain medicines to treat allergic reactions (antihistamines), such as terfenadine, astemizole and mizolastine
  • Medicines used to treat or prevent malaria, such as quinine, mefloquine, chloroquine and halofantrine

If any of the above applies to you, do not use this medicine and talk to your doctor or nurse.

Other medicines and Amiodarone Injection

Tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicine.

  • Oral anticoagulants e.g. warfarin (used to thin the blood), phenytoin (used to treat epilepsy) and digoxin (used to treat certain heart conditions). Your doctor may reduce your dose of these medicines and your blood will need to be monitored before and after treatment
  • Stimulant laxatives such as bisacodyl and senna, medicines called diuretics or water tablets, steroids and the antifungal medicine amphotericin (when given directly into the vein). These can cause low levels of potassium in the blood, which can increase the risk of getting a fast heart rate (tachycardia).
  • Rifampicin (an antibiotic) and St. John’s Wort (a herbal medicine) can cause lower levels of Amiodarone Injection in the body if they are taken at the same time
  • Medicines that can either be affected by or effect the level of amiodarone in the body if taken at the same time:
  • Ciclosporin, tacrolimus (immunosuppressants- used to help prevent rejection of transplants)
  • Flecainide, used to treat irregular heart rhythms. Your doctor should monitor your treatment closely and may adjust your dose of flecainide.
  • Simvastatin, lovastatin, atorvastatin (drugs to reduce blood cholesterol), as there is a risk of developing muscle pains and kidney failure (rhabdomyolysis) if doses of more than 20 mg of simvastatin are taken
  • Lidocaine (a local anaesthetic)
  • Sildenafil (used for erectile dysfunction)
  • Fentanyl (used for pain relief)
  • Midazolam and triazolam (a sedative)
  • Ergotamine and dihydroergotamine (for migraine)
  • Colchicine (for gout)
  • Beta-blockers, such as metoptolol and sotalol
  • Calcium channel blockers diltiazem and verapamil, used to treat high blood pressure
  • Indinavir (an anti-viral drug)
  • Cimetidine (an anti-ulcer drug)
  • Clarithromycin (an antibiotic)
  • Ketoconazole and itraconazole (antifungal drugs)
  • Tetracosactrin ( used in the treatment of inflammatory or degenerative disorders)
  • Sofosbuvir, used for the treatment of hepatitis C

Amiodarone Injection with food and drink

Do not drink grapefruit juice while using this medicine because it can increase amiodarone levels in your blood.

Protect your skin from sunlight

Keep out of direct sunlight while using this medicine and for a few months after you have finished using it. This is because your skin will become much more sensitive to the sun and may burn, tingle or severely blister if you do not take the following precautions:

  • make sure you use a high factor sun cream
  • always wear a hat and clothes which cover your arms and legs

Pregnancy and breast-feeding

  • Your doctor will prescribe amiodarone injection only in exceptional circumstances, if the benefit of treatment outweighs the risks during your pregnancy. Amiodarone can be used during pregnancy in life-threatening circumstances only.
  • You should not be given amiodarone if you are breast-feeding. If you are given amiodarone during pregnancy or breast-feeding, breast-feeding should be stopped. If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Driving and using machines

Some of the side effects in section 4 together with how you feel after your treatment may make it unsafe for you to drive or operate machinery. If you feel unwell, you must speak to your doctor or nurse before driving or operating machinery.

Important information about some of the ingredients of Amiodarone Injection

Amiodarone Injection contains Benzyl Alcohol

This medicine contains 200mg of Benzyl Alcohol in each 10ml syringe. Benzyl Alcohol may cause allergic reactions. Ask your doctor or pharmacist for advice if you have liver or kidney disease or if you are pregnant or breast-feeding. This is because large amounts of benzyl alcohol can build-up in your body and may cause side effects (called “metabolic acidosis”).

Benzyl alcohol has been linked with toxic and allergic reactions called gasping syndrome in infants and children up to 3 years old

This medicine contains:

  • Iodine: Amiodarone Injection contains approximately 112mg of iodine in a 10ml pre-filled syringe. Iodine is present in amiodarone hydrochloride, the medicine your infusion contains. Iodine can cause problems with your thyroid (see ‘Tests’ below)

3. How Amiodarone Injection is given

Your doctor or nurse will normally give you Amiodarone Injection. This is because it needs to be given as an injection or infusion into your vein in the hospital where the doctor can monitor your progress.


The daily dose of Amiodarone depends on the severity of your illness. The dose and the treatment times will be determined by your doctor, who will adjust these especially for you.

Unless otherwise prescribed by your doctor, the usual dose is 5 mg per kg of body weight. Your medicine will be injected over a period of at least 3 minutes.

When Amiodarone is given as an injection

  • you should not be given a dose greater than 5 mg per kg of body weight.
  • the dose should be given to you slowly over a period of at least 3 minutes (unless you are being given the medicine for resuscitation).
  • the doctor must wait for at least 15 minutes before giving you another injection.
  • repeated or continuous administration may cause inflammation of the vein and damage to the skin at the injection site (the surrounding skin may feel warm and tender and redness may be present) and in such situations a “central venous catheter” is recommended for use by your doctor.

When Amiodarone is given as an infusion

  • you should be given a dose of 5 mg/kg bodyweight diluted in 250 ml of 5% dextrose solution.
  • the dose should be given to you over a period of 20 minutes to 2 hours.
  • The administration may be repeated 2-3 times per day. Most of the side effects which occur during treatment occur if you are given too much Amiodarone. You should therefore be given the lowest possible dose of Amiodarone. This will keep side effects to a minimum. See also “If you have received more Amiodarone than you should”.


The usual dose is 5 mg for every kilogram of your weight given over a period of 20 minutes to 2 hours.

You may be given another dose of 10 to 20 mg for every kilogram of weight every 24 hours depending on your illness.

In an emergency, your doctor may decide to give you a dose of 150 mg to 300 mg as a slow injection over 3 minutes.

Your doctor will monitor your response to Amiodarone and the dose will be adjusted accordingly.

Children and adolescents:

  • There is only limited information on the use in children. The child’s doctor will carefully calculate the amount of Amiodarone Injection depending on the child’s body weight.

This medicine is not for use in neonates, infants and children up to 3 years old.


  • As with all patients it is important that the minimum effective dose is used. Your doctor will carefully calculate how much Amiodarone you should get and monitor your heart rate and thyroid function more closely.

If you are given too much Amiodarone Injection

Your doctor will carefully calculate how much Amiodarone Injection you should get, therefore it is unlikely your doctor or nurse will give you too much of it. If, however, you have received higher doses than those recommended you will be carefully monitored by your doctor and will receive supportive therapy if necessary.

If you are given too much Amiodarone Injection the following effects may happen: feeling dizzy, faint, sick, tired, confused, constipation or sweating.

You may have an abnormally slow or fast heartbeat. Too much amiodarone can damage the heart and liver.

If you forget to have Amiodarone Injection

Your doctor or nurse will have instructions on when to give you this medicine. It is unlikely that you will not be given the medicine as it has been prescribed. However, if you think you may have missed a dose, then talk to your doctor or nurse.

If you stop having Amiodarone Injection

It is important for you to keep having Amiodarone Injections until your doctor decides to stop them. If you stop having this medicine, the uneven heartbeats may come back and this could be dangerous.


  • Your doctor will take regular tests to check how your liver is working. Amiodarone Injection can affect how your liver works. If this happens, your doctor will decide whether you should keep having this medicine
  • Your doctor will do regular thyroid tests while you are taking this medicine. This is because Amiodarone Injection contains iodine which can cause problems with your thyroid
  • Your doctor may also do other regular tests such as blood tests, chest X-rays, ECG (electrical test of your heartbeat) and eye tests both before and while you are having Amiodarone Injection. If you have any further questions on the use of this product, ask your doctor.
