Take Home Naloxone Program

Naloxone is a drug that can temporarily reverse the effects of an opioid overdose or adverse reaction. It is administered by injection or delivered through a nasal spray and works by blocking opioid drugs from attaching to opioid receptors in the brain.

The Take Home Naloxone (THN) Program will make the medicine naloxone free and available without a prescription to people who are at risk of, or who may witness, an opioid overdose or adverse reaction. The 2022-23 Federal Budget included $19.6 million (over four years), for a national, ongoing THN Program. The program was initially piloted in New South Wales, South Australia and Western Australia before being expanded nationally from 1 July 2022.
