Substance Use: Naloxone
Naloxone is a medication that can reverse an overdose caused by an opioid drug like fentanyl, heroin, or prescription pain medications. When given during an overdose, naloxone blocks the effects of opioids on the brain and quickly restores breathing.
Naloxone has been used safely by emergency medical professionals for more than 40 years and has only one important function: to stop overdose death by reversing the effects of opioids. Naloxone is a safe, non-controlled drug and has no potential for misuse.
If naloxone is given to a person who is not going through an opioid overdose, it is harmless. If naloxone is given to a person who is dependent on opioids, it will cause withdrawal symptoms. Withdrawal, although uncomfortable, is not life-threatening.
Naloxone is widely available in Wisconsin. It is available as a nasal spray or an injection.
The use of other opioid overdose reversal medications is not recommended. See our statement on long-acting, high-dose opioid overdose medication.
It’s dangerous to take opioids when you are alone. If a trusted family member or friend is around and alert, they can look for the signs of an opioid overdose and administer naloxone if needed. If a trusted family member or friend is not available, call Never Use Alone or SafeSpot.

- Share that naloxone is for anyone who uses opioids and other substances that are commonly mixed with fentanyl or other synthetic opioids. Naloxone is effective for any opioid overdose, including prescription pain reliever, heroin, and fentanyl overdoses.
- Meet them where they’re at. They may be struggling, so offer your support by listening and giving them your undivided attention. Let them know they’re important to you. That’s why preparing for an emergency by carrying naloxone is so important.
- Know the real facts about naloxone and help call out misinformation. They should know that carrying naloxone won’t get them in trouble.
- Emphasize that carrying naloxone is normal and responsible. Point out that many doctors and pharmacists recommend providing naloxone with every opioid prescription. This can help reduce a potential fear of judgment.
