What is Naloxone?
- Naloxone (pronounced na-LOX-own) is a prescription medication used to temporarily reverse the effects of opioid drugs (for example heroin, morphine, codeine, methadone and fentanyl) if someone experiences an overdose.
- Naloxone can help to keep a person alive until an ambulance arrives.
- Naloxone works by displacing opioid molecules from their receptors in the body and brain.
