What You'll Learn

Nasal spray
Naloxone, sold under the brand name Narcan, is a nasal spray medication used to rapidly reverse the effects of an opioid overdose. It is available as an over-the-counter medicine in the United States and can be easily administered by following these steps:
Firstly, check for signs of an opioid overdose, which may include slowed breathing or unresponsiveness, pinpoint pupils, slow heartbeat, or extreme sleepiness. If the person exhibits any of these symptoms, lay them on their back with their head tilted up.
Then, administer the nasal spray by inserting the device into one nostril and pressing the plunger firmly. Each spray contains 4 milligrams of naloxone, which competes with opioids to bind to the same receptors in the brain, reversing the effects of the overdose.
After administering the first dose, call 911 immediately and continue to give another dose every 2 to 3 minutes, alternating nostrils, until the patient responds or emergency medical assistance arrives. It is important to note that this medication is only a temporary solution, and the patient should still receive professional medical attention as soon as possible.
Narcan Nasal Spray is a crucial tool in responding to opioid emergencies, and its accessibility and ease of use make it an important resource for those at risk of opioid overdose or those close to someone at high risk. By carrying Narcan Nasal Spray and knowing how to administer it, you can make a life-saving difference in an emergency situation.

Intramuscular needle syringe
Naloxone, sold under the brand name Narcan, is a medication used to counter the effects of opioid overdose. It is typically administered intramuscularly using a needle syringe.
- Preparation: Ensure you are wearing personal protective equipment (PPE), including gloves, to reduce the risk of infection. Gather the necessary supplies, including the Narcan syringe, alcohol wipes, and a sharps container for safe disposal. Check the expiration date on the syringe packaging and verify the dosage and concentration of the Narcan solution.
- Assembly: Remove the syringe from its packaging carefully. Attach the appropriate needle size for intramuscular injection, typically a longer needle, to the syringe securely. Remove the protective cap from the needle and set it aside, being mindful of sharps safety.
- Drawing the Medication: Hold the syringe by the barrel and gently tap the side to ensure the air bubbles rise to the top. Carefully push the plunger to expel the air bubbles and ensure the syringe is properly filled with the Narcan solution. Double-check the dosage and ensure there are no air bubbles remaining in the syringe before administration.
- Patient Positioning: Ensure the patient is positioned appropriately for intramuscular injection. Common injection sites include the upper arm (deltoid muscle) or upper outer quadrant of the gluteal region (dorsogluteal muscle). Clean the injection site with an alcohol wipe to maintain sterility.
- Administration: With your free hand, stabilize the patient's arm or leg to ensure proper control during injection. Quickly insert the needle into the chosen muscle at a 90-degree angle and push the plunger down slowly to administer the Narcan solution. Ensure the needle remains in the muscle throughout the injection process.
- Withdrawal: Once the solution has been completely administered, carefully remove the needle by first pulling the needle out of the muscle and then gently separating it from the syringe, being cautious to avoid accidental needle sticks. Dispose of the used needle and syringe in the designated sharps container immediately.
It is important to monitor the patient closely after administering Narcan. Intramuscular injection typically leads to a faster onset of action, and the patient may exhibit withdrawal symptoms as the effects of opioids are reversed. Be prepared to provide supportive care and seek further medical assistance as needed.

Evzio auto-injector
Naloxone, the active ingredient in Narcan, is used to rapidly reverse the effects of an opioid overdose in a hospital setting. It is available as an over-the-counter nasal spray and an auto-injector.
The Evzio auto-injector is a device used to deliver a dose of naloxone to someone experiencing an opioid overdose. It is a small, portable device that can be carried in a pocket or purse, and it contains a pre-filled syringe of naloxone. Evzio is designed to be easy to use, with step-by-step voice instructions that guide the user through the process of administering the medication.
To use the Evzio auto-injector, first remove the red safety cap from the device. Place the black end of the device firmly against the outer thigh of the person experiencing the overdose. Press and hold the device firmly in place for 5 seconds after you hear a click and a hissing sound. This means that the medication has been injected and the needle will automatically retract back into the device.
It is important to call 911 immediately after administering Evzio, even if the person appears to be recovering. Stay with the person and monitor their breathing and responsiveness until help arrives. Evzio is intended for emergency use only and is not a substitute for immediate medical care.
Evzio is a potentially life-saving device that can be used by anyone, not just medical professionals. It is important to note that Evzio is not a substitute for seeking immediate medical attention in the event of an opioid overdose.

Rezenopy® spray
The recommended dosage of Rezenopy® spray is one spray into one nostril, and it can be administered to either nostril. If the patient does not respond within 2 to 3 minutes or responds and then relapses into respiratory depression, an additional dose may be given into the other nostril with a new device. However, it is important not to administer more than two sprays per day. Rezenopy® spray should not be used in patients who are opioid-dependent, as it may precipitate severe opioid withdrawal. In patients with pre-existing cardiovascular disorders or those who have received drugs with similar adverse cardiovascular effects, abrupt reversal of breathing problems caused by opioid administration post-surgery may lead to adverse cardiovascular events. Therefore, close monitoring in an appropriate healthcare setting is necessary in this patient population.
