What is naloxone nasal spray used for?
Naloxone nasal spray is an emergency medicine used to reverse opioid overdose. It can quickly restore breathing in someone whose breathing has slowed or stopped due to opioids such as heroin, fentanyl, oxycodone, or morphine. Because it is given through the nose, it’s designed for use without needles in urgent situations.
How does naloxone nasal spray work?
Naloxone blocks opioid receptors in the body. When opioids are causing overdose symptoms, naloxone can counter those effects and help breathing return. Effects can wear off before the opioids are fully cleared, so overdose symptoms may come back, requiring additional doses and continued emergency care.
When should you use naloxone nasal spray?
Use it right away if someone is suspected of having an opioid overdose—especially if they are unresponsive and not breathing normally (slow, weak, or stopped breathing), or if breathing has significantly decreased. In most overdose response instructions, naloxone is paired with calling emergency services immediately.
How do you give it?
Naloxone nasal spray is administered by spraying into one nostril. Many products include specific instructions on how to hold the device and when to give a second dose. Follow the instructions included with the particular product you have on hand, because nasal-spray delivery steps can vary by brand.
What if the person doesn’t improve?
If breathing does not improve after the first dose, emergency overdose instructions commonly call for giving another dose and continuing to monitor breathing while waiting for responders. Opioid overdoses can involve long-acting opioids or high potency opioids (like fentanyl), which may outlast the reversal effect of a single naloxone dose.
Do naloxone nasal spray and other forms differ?
Naloxone comes in multiple formats, including nasal sprays and injectables. The key practical difference is the route of administration: nasal spray is needle-free and easier for bystanders to use quickly. The underlying goal is the same—opioid reversal.
Is it safe if the cause isn’t definitely opioids?
Naloxone is targeted to opioid effects. If the symptoms are not from opioids, naloxone may have little effect, but it can still be used when opioid overdose is suspected strongly, because untreated overdose is immediately life-threatening.
Patient and caregiver questions people often have
People also ask whether naloxone can be used for children and whether it can be used alongside other overdose interventions. The standard approach is that naloxone is used as soon as overdose is suspected, with dosing and device instructions depending on the product. Caregivers typically should keep naloxone accessible and trained on its use.
