If you’re taking opioids, it’s important that the people you live with know when and how to use naloxone. Ask everyone to read the instructions that come with your prescription. They should also know where to find it in your home in case you need it.
What is naloxone and what is it used for?
Naloxone is a medication that can reverse or block the effects of an opioid overdose. An opioid overdose is when your breathing slows down or stops. This happens if you take more opioids than your healthcare provider prescribes you.
Why do I need naloxone?

Using them too much or in the wrong way can lead to a strong, harmful need to keep using them. For more information, read Safe Opioid Use: What You Need to Know .
