How Gentamicin Injection is given

How much is given

Your doctor will decide what dose you will receive. This depends on your condition and other factors, such as your age, weight, and kidney function.

How it is given

Gentamicin Injection must only be given by a doctor, nurse or other trained person. It is given as an injection into a muscle or as a slow injection into a vein (intravenously).

If you are given too much (overdose)

As Gentamicin Injection is usually given to you in hospital under the supervision of your doctor, it is very unlikely that you will receive an overdose.

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Gentamicin Injection. Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

Symptoms of a gentamicin overdose may include the side effects listed below in the ‘Side Effects’ section, but are usually of a more severe nature.
