How Narcan® Injection is given

Narcan® Injection must only be given by a doctor or a healthcare professional.

How it is given

Narcan® Injection can be given:

  • as an injection into a muscle (intramuscular),
  • just under the skin (subcutaneous) or
  • as a slow injection into a vein (intravenous).

How much is given

Your doctor will decide what dose of Narcan® Injection you will receive and how long you will receive it for. This depends on your medical condition and other factors.

Sometimes only a single dose of Narcan® Injection is required.

If you are given too much (overdose)

As Narcan® Injection is always given to you in a hospital under the supervision of a doctor, it is unlikely that you will receive an overdose.

Symptoms of an overdose may be the same as side effects but may be more severe. The symptoms of a side effect are listed under Side effects below.

If you notice any symptoms of an overdose immediately contact your doctor or go to the Emergency Department at the nearest hospital.

Contact the Poisons Information Centre on 13 11 26 for further advice on overdose management.

Things to be careful of
