What is naloxone?

Naloxone is a free, life-saving medicine that reverses the effects of opioids. It temporarily blocks the opioid reaction in the brain, effectively reversing severe opioid side effects (sometimes called opioid overdose). This can allow enough time for emergency services to arrive.

Naloxone is safe and effective. Even if it is given to someone who is not experiencing a severe opioid reaction, it will cause no harm.

How to use naloxone:

  • Naloxone is available as a nasal spray and an injection (like an EpiPen). It is free and readily available at most pharmacies without a prescription.
  • To administer naloxone as a nasal spray, spray one dose into the nostril.
  • If using the injection, inject one dose into the outer shoulder or thigh muscle.
  • Note the time of administration. If there is no response after 2-3 minutes, repeat the dose.
  • The effects of naloxone are temporary - they last for approximately 20 minutes. Ensure that emergency services are on their way. Call emergency services on 000.

Keeping naloxone at home could save a life.

If you take prescribed opioids, or if you care for or know someone who takes prescribed opioids, having naloxone at home can save a life.

Why should you have naxolone at home?

Naloxone temporarily reverses the effects of opioids. If you suspect someone has had a severe reaction to opioids - if their breathing has slowed or stopped, if they are unresponsive or if they are displaying any other signs of a severe reaction, then administering naloxone could save their life.
It's safe - Even if naloxone is given to someone who has not taken opioids (e.g. someone may be unconscious for other reasons), it will not do any harm.
Naloxone can be administered while waiting for emergency services to arrive. This could save a life.
