Important information about some of the ingredients of Amikacin Injection

This medicine contains sodium metabisulphite, which may rarely cause hypersensitivity (severe allergy) reactions and bronchospasm (breathing difficulties).

This medicinal product contains less than 1 mmol (23 mg) sodium per dose, i.e. essentially ‘sodium free’.

How to use Amikacin injection

This medicine is usually injected into a muscle. It may also be given into a vein, either as an injection or (following dilution) as an infusion (drip).

Amikacin can also be given into the peritoneum (abdominal cavity) during surgery, and can be used to wash out abscess cavities, the lung cavity and brain cavities.


Your doctor will work out the correct dose of amikacin for you and how often it must be given.

The dose will depend upon your age, the infection you have, how well your kidneys are working, if you have poor hearing and any other medicines you may be taking.

It will usually be given to you two or three times a day, for up to 10 days.

Adults and children over 12 years:

The usual dose is 15 mg per kg which is administered as a single dose or divided into two equal doses of 7.5 mg per kg administered every 12 hours. The total dose should not exceed 1.5 g.

Children up to 12 years:

The usual dose is 15-20 mg per kg of body weight once a day or divided into two equal doses of 7.5 mg per kg which is administered every 12 hours.


The initial dose is 10 mg per kg of body weight followed by 7.5 mg per kg every 12 hours.

Premature infants:

The recommended dosing in premature babies is 7.5 mg per kg every 12 hours.

During treatment you may undergo blood tests, be asked to provide urine samples and possibly have hearing tests to look for signs of side effects. Your doctor may change your dose depending upon the results of these tests.

If you are given too much or too little Amikacin Injection

This medicine will be given to you in a hospital, under the supervision of a doctor. It is unlikely that you will be given too much or too little, however, tell your doctor or nurse if you have any concerns.

Like all medicines, amikacin can cause side effects, although not everybody gets them.

If any of the following happens, tell your doctor immediately:

  2. ringing in your ears or loss of hearing
  3. decrease in the amount of urine you produce

These are serious side effects. You may need urgent medical attention.

  5. fever
