Administration
* During cardiopulmonary resuscitation, the same dosage may be given via the intraosseous route when IV access is unsuccessful or not feasible.
* Inhalation Administration
* Oral Inhalation Administration
* NOTE: Naloxone is not FDA-approved for oral inhalation administration.
* Dilute 2 mg in 3 mL of 0.9% Sodium Chloride Injection.
* Administer through a standard face mask.
* Other Administration Route(s)
* Intranasal Administration
Instructions for Caregivers and Family
* Alert others about the presence of naloxone nasal spray, as administration must be performed by someone other than the patient. Family members, caregivers, or other people who may have to use naloxone in an opioid emergency should know the signs and symptoms of opioid overdose, where the nasal spray is stored, and how to administer the drug before an opioid emergency occurs. Once obtained, become familiar with how to use the nasal spray by reading the instructions.
* Those who administer naloxone should be aware that its use in patients who are opioid dependent may precipitate opioid withdrawal. In neonates, opioid withdrawal can be life-threatening and must be treated immediately.
* Instruct patients and their family members or caregivers that the reversal of respiratory depression caused by partial agonists or mixed agonist/antagonists such as buprenorphine and pentazocine, may be incomplete. Higher doses or repeated administrations of naloxone may be needed.
Administration
* Administer naloxone nasal spray as quickly as possible if a patient is unresponsive and an opioid overdose is suspected, even when in doubt. Prolonged respiratory depression may result in central nervous system damage or death.
* Hold the device with your thumb on the bottom of the plunger and your first and middle fingers on either side of the nozzle.
* Place the patient in the supine position. Assure that the device nozzle is inserted into 1 of the patient's nostrils and provide support to the back of the neck to allow the head to tilt back. Both of your fingers on either side of the nozzle should be against the bottom of the patient's nose.
Administration
* Inject undiluted solution subcutaneously taking care not to inject intradermally.
Subcutaneous Injection with Auto-injector (Zimhi)
Instructions for Caregivers and Family
* Because treatment of suspected opioid overdose must be performed by someone other than the patient, caregivers and people in close contact with the recipient should be informed of the presence of Zimhi and its instructions for use before the need for the medication arises.
* Prior to a medical emergency (during storage), periodically visually inspect Zimhi through the viewing window on the device. If the solution is discolored yellow or brown color, cloudy, or contains particles, replace Zimhi with a new one.
* Zimhi is intended to be administered by individuals 12 years of age or older. Younger individuals or those with limited hand strength may find the device difficult to use.
* Those who administer Zimhi should be aware that the use of naloxone in patients who are opioid dependent may cause an acute abstinence syndrome. In neonates, opioid withdrawal can be life-threatening and must be treated immediately.
* Instruct patients and their family members or caregivers that the reversal of respiratory depression caused by partial agonists or mixed agonist/antagonists such as buprenorphine and pentazocine, may be incomplete. Higher than usual doses of naloxone may be needed.
Administration
* Remove the needle cap to expose needle; do not attempt to re-cap the needle with the needle cap once it has been removed.
* Administer subcutaneously, as quickly as possible, into the anterolateral aspect of the thigh, through clothing if necessary. Ensure the needle is embedded completely before pushing the plunger. Push the plunger firmly all the way down until it clicks and hold in place for 2 seconds.
* For neonates and infants: The caregiver should pinch the middle of the outer thigh muscle prior to and during drug administration. Carefully observe the administration site for evidence of residual needle parts and/or signs of infection.
* Immediately after the injection, using one hand with fingers behind the needle, slide the safety guard over the needle. Do not use two hands to activate the safety guard.
Administration
* Inhalation Administration
* Oral Inhalation Administration
* NOTE: Narcan is not FDA-approved for oral inhalation administration.
* Dilute 2 mg in 3 mL of 0.9% Sodium Chloride Injection.
* Administer through a standard face mask.
* Other Administration Route(s)
* Intranasal Administration
Instructions for Caregivers and Family
* Alert others about the presence of narcan nasal spray, as administration must be performed by someone other than the patient. Family members, caregivers, or other people who may have to use narcan in an opioid emergency should know the signs and symptoms of opioid overdose, where the nasal spray is stored, and how to administer the drug before an opioid emergency occurs. Once obtained, become familiar with how to use the nasal spray by reading the instructions.
* Those who administer narcan should be aware that its use in patients who are opioid dependent may precipitate opioid withdrawal. In neonates, opioid withdrawal can be life-threatening and must be treated immediately.
* Instruct patients and their family members or caregivers that the reversal of respiratory depression caused by partial agonists or mixed agonist/antagonists such as buprenorphine and pentazocine, may be incomplete. Higher doses or repeated administrations of narcan may be needed.
Administration
* Administer narcan nasal spray as quickly as possible if a patient is unresponsive and an opioid overdose is suspected, even when in doubt. Prolonged respiratory depression may result in central nervous system damage or death.
* Hold the device with your thumb on the bottom of the plunger and your first and middle fingers on either side of the nozzle.
* Place the patient in the supine position. Assure that the device nozzle is inserted into 1 of the patient's nostrils and provide support to the back of the neck to allow the head to tilt back. Both of your fingers on either side of the nozzle should be against the bottom of the patient's nose. DO NOT prime or test the device prior to administration.
* Press firmly on the device plunger to administer the dose.
* Remove the device nozzle from the nostril.
Administration
Aspirate prior to injection to avoid injection into a blood vessel.
Intramuscular Injection with Auto-injector (Zimhi)
Instructions for Caregivers and Family
* Because treatment of suspected opioid overdose must be performed by someone other than the patient, caregivers and people in close contact with the recipient should be informed of the presence of Zimhi and its instructions for use before the need for the medication arises.
* Prior to a medical emergency (during storage), periodically visually inspect Zimhi through the viewing window on the device. If the solution is discolored yellow or brown color, cloudy, or contains particles, replace Zimhi with a new one.

* Administer intramuscularly, as quickly as possible, into the anterolateral aspect of the thigh, through clothing if necessary. Ensure the needle is embedded completely before pushing the plunger. Push the plunger firmly all the way down until it clicks and hold in place for 2 seconds.
* For neonates and infants: The caregiver should pinch the middle of the outer thigh muscle prior to and during drug administration. Carefully observe the administration site for evidence of residual needle parts and/or signs of infection.
