An overdose of opioids such as morphine, heroin, methadone or oxycodone – sometimes mixed with fentanyl – can cause a person’s breathing to slow down or stop.

Naloxone is a safe, affordable medication that can quickly reverse the effects of an opioid overdose. It is given by injection and can be administered with minimal training. It is usually injected into the thigh or shoulder and can be given through clothing if needed.

Naloxone is generally effective when an opioid is causing the overdose. It may not work if other drugs are involved. However, naloxone does not cause harmful effects in a person who has not taken opioids.

Paramedics and other first responders carry naloxone and can administer it to people with a suspected opioid overdose.

The Take-Home Naloxone Program provides naloxone kits, including breathing masks, to members of the public. Visit the program website to learn more.
