Narcan Nasal Spray
Common Name:
naloxone
How does Narcan Nasal Spray work? What will it do for me?
Naloxone belongs to the class of medications called opiate antagonists. It is used to reverse or prevent the effects of too much narcotic medication (codeine, fentanyl, morphine, oxycodone) having been taken. It works by blocking the activity of the narcotic medication, reversing the effects of the narcotic that may be life threatening. Signs of a narcotic overdose include trouble breathing, extreme drowsiness, pale and clammy skin, slow or no heartbeat, difficulty waking up, or unconsciousness.
Depending on how it is given, naloxone may begin to work as quickly as 1 to 5 minutes after it has been given.

How should I use Narcan Nasal Spray?
Before using this medication, call 9-1-1 to request emergency medical assistance. This medication should not be used as a substitute for professional medical care.
Naloxone nasal spray is available as a 2 mg or a 4 mg spray device. The lowest available strength should be used as the starting dose. If the person responds to the first dose, but overdose symptoms reappear before emergency help arrives, administer additional doses of naloxone. If the person does not respond to the first dose of naloxone after 2 to 3 minutes, administer repeated doses of naloxone as necessary.
Each nasal spray device contains a single dose of naloxone and cannot be reused. To administer naloxone nasal spray, place patient on their back. Support the back of the neck to allow the head to tilt back. Ensure the device nozzle is inserted in either nostril and press firmly on the device plunger. Remove the device nozzle after use.
If repeat doses are needed, alternate nostrils for each dose.

Are there any other precautions or warnings for Narcan Nasal Spray?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Non-opioid overdoses: This medication does not reduce the effects of an overdose caused by other medications such as barbiturates, benzodiazepines, stimulants, alcohol, or other sedatives. Giving this medication to a person who is unconscious due to a non-opioid overdose is not likely to cause them more harm.
Opioid dependence: When given to a person who has been using opioids for a long time, naloxone may cause withdrawal symptoms similar to stopping the opioid suddenly. These symptoms can include body aches, diarrhea, nausea, nervousness, restlessness, runny nose, sneezing, goose bumps, shaking, shivering, nausea, stomach cramps, fast or irregular heart rate, fever, sweating, increased blood pressure, and possible seizures.
Rebound opioid toxicity: The effects of naloxone are shorter than the effects of opioids. As a result, symptoms of overdose may reappear when naloxone wears off. Additional doses of naloxone may be required.
Recent surgery: This medication should be used with caution in someone who has had recent surgery. Side effects such as blood pressure changes, increased heart rate, irregular heartbeat, fluid build-up in the lungs and heart attack have been reported.
Pregnancy: The effects of naloxone on a developing baby are unknown. This medication should not be used during pregnancy unless the benefits outweigh the risks.
Breast-feeding: It is not known if naloxone passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
