FULL PRESCRIBING INFORMATION

1 INDICATIONS AND USAGE

NALOXONE AUTO-INJECTOR is an opioid antagonist indicated for the emergency treatment of known or suspected opioid overdose, as manifested by respiratory and/or central nervous system depression in adults and pediatric patients.

NALOXONE AUTO-INJECTOR is intended for immediate administration as emergency therapy in settings where opioids may be present.

NALOXONE AUTO-INJECTOR is not a substitute for emergency medical care.

2 DOSAGE AND ADMINISTRATION

2.1 Important Administration Instructions

NALOXONE AUTO-INJECTOR is for intramuscular and subcutaneous use only.

Because treatment of suspected opioid overdose must be performed by someone other than the patient, instruct the prescription recipient to inform those around them about the presence of NALOXONE AUTO-INJECTOR and the Instructions for Use.

Instruct the patient or caregiver to read the Instructions for Use at the time they receive a prescription for NALOXONE AUTO-INJECTOR. Emphasize the following instructions to the patient or caregiver:

  • Seek emergency medical care immediately after use. Since the duration of action of most opioids exceeds that of naloxone hydrochloride and the suspected opioid overdose may occur outside of supervised medical settings, seek immediate emergency medical assistance, keep the patient under continued surveillance until emergency personnel arrive, and administer repeated doses of NALOXONE AUTO-INJECTOR as necessary. Always seek emergency medical assistance in the event of a suspected potentially life-threatening opioid emergency after administration of the first dose of NALOXONE AUTO-INJECTOR.
  • Additional doses of NALOXONE AUTO-INJECTOR may be required until emergency medical assistance becomes available.
  • Do not attempt to reuse NALOXONE AUTO-INJECTOR. Each NALOXONE AUTO-INJECTOR contains a single dose of naloxone.
  • Visually inspect NALOXONE AUTO-INJECTOR through the viewing window for particulate matter and discoloration prior to administration. Do not administer unless the solution is clear and the glass container is undamaged.
  • NALOXONE AUTO-INJECTOR must be administered according to the printed instructions on the device label or the electronic voice instructions (NALOXONE AUTO-INJECTOR contains a speaker that provides voice instructions to guide the user through each step of the injection). If the NALOXONE AUTO-INJECTOR electronic voice instruction system does not operate properly, NALOXONE AUTO-INJECTOR will still deliver the intended dose of naloxone hydrochloride when used according to the printed instructions on its label.
  • Once the red safety guard is removed, NALOXONE AUTO-INJECTOR must be used immediately or disposed of properly. Do not attempt to replace the red safety guard once it is removed.

Upon actuation, NALOXONE AUTO-INJECTOR automatically inserts the needle intramuscularly or subcutaneously, delivers the naloxone hydrochloride injection, and retracts the needle fully into its housing. Post injection, the black base locks in place, a red indicator appears in the viewing window, and electronic visual and audible instructions signal that NALOXONE AUTO-INJECTOR has delivered the intended dose of naloxone hydrochloride and instructs the user to seek emergency medical attention.

2.2 Dosing Information

Initial Dosing

Administer the initial dose of NALOXONE AUTO-INJECTOR to adult or pediatric patients intramuscularly or subcutaneously into the anterolateral aspect of the thigh, through clothing if necessary, and seek emergency medical assistance. Administer NALOXONE AUTO-INJECTOR as quickly as possible because prolonged respiratory depression may result in damage to the central nervous system or death.

Repeat Dosing

The requirement for repeat doses of NALOXONE AUTO-INJECTOR depends upon the amount, type, and route of administration of the opioid being antagonized.

If the desired response is not obtained after 2 or 3 minutes, an additional dose of NALOXONE AUTO-INJECTOR may be administered. If there is still no response and additional doses are available, additional doses of NALOXONE AUTO-INJECTOR may be administered every 2 to 3 minutes until emergency medical assistance arrives. Additional supportive and/or resuscitative measures may be helpful while awaiting emergency medical assistance.

If the patient responds to NALOXONE AUTO-INJECTOR and relapses back into respiratory depression before emergency assistance arrives, an additional dose of NALOXONE AUTO-INJECTOR may be administered.

Reversal of respiratory depression by partial agonists or mixed agonist/antagonists, such as buprenorphine and pentazocine, may be incomplete and may require higher doses of naloxone hydrochloride or repeated administration of NALOXONE AUTO-INJECTOR.

Dosing in Adults and Pediatric Patients over Age One Year

Instruct patients or their caregivers to administer NALOXONE AUTO-INJECTOR according to the Instructions for Use, intramuscularly or subcutaneously.

Dosing in Pediatric Patients under Age One Year

In pediatric patients under the age of one year, the caregiver should pinch the thigh muscle while administering NALOXONE AUTO-INJECTOR. Carefully observe the administration site for signs of infection following injection and resolution of the opioid emergency.

There may be clinical settings, particularly the postpartum period in neonates with known or suspected exposure to maternal opioid use, where it is preferable to avoid the abrupt precipitation of opioid withdrawal symptoms. In these settings, consider use of an alternative, naloxone product which can be titrated to effect and, where applicable, dosed according to weight [see Use in Specific Populations (8.4)].

3 DOSAGE FORMS AND STRENGTHS

2 mg Injection: 2 mg/0.4 mL naloxone hydrochloride solution in a pre-filled auto-injector. Each NALOXONE AUTO-INJECTOR 2 mg delivers 2 mg naloxone hydrochloride injection (0.4 mL).

4 CONTRAINDICATIONS

NALOXONE AUTO-INJECTOR is contraindicated in patients known to be hypersensitive to naloxone hydrochloride or to any of the other ingredients.

5 WARNINGS AND PRECAUTIONS

5.1 Risk of Recurrent Respiratory and Central Nervous System Depression

The duration of action of most opioids may exceed that of NALOXONE AUTO-INJECTOR resulting in a return of respiratory and/or central nervous system depression after an initial improvement in symptoms. Therefore, it is necessary to seek emergency medical assistance immediately after delivering the first dose of NALOXONE AUTO-INJECTOR. Keep the patient under continued surveillance and administer additional doses of NALOXONE AUTO-INJECTOR as necessary [see Dosage and Administration (2.2)]. Additional supportive and/or resuscitative measures may be helpful while awaiting emergency medical assistance.

5.2 Risk of Limited Efficacy with Partial Agonists or Mixed Agonist/Antagonists

Reversal of respiratory depression by partial agonists or mixed agonist/antagonists such as buprenorphine and pentazocine, may be incomplete. Larger or repeat doses of naloxone hydrochloride may be required to antagonize buprenorphine because the latter has a long duration of action due to its slow rate of binding and subsequent slow dissociation from the opioid receptor [see Dosage and Administration (2.2)]. Buprenorphine antagonism is characterized by a gradual onset of the reversal effects and a decreased duration of action of the normally prolonged respiratory depression.

5.3 Precipitation of Severe Opioid Withdrawal

The use of NALOXONE AUTO-INJECTOR in patients who are opioid dependent may precipitate an acute abstinence syndrome characterized by the following signs and symptoms: body aches, diarrhea, tachycardia, fever, runny nose, sneezing, piloerection, sweating, yawning, nausea or vomiting, nervousness, restlessness or irritability, shivering or trembling, abdominal cramps, weakness, and increased blood pressure. In neonates, opioid withdrawal may be life-threatening if not recognized and properly treated and may include the following signs and symptoms: convulsions, excessive crying and hyperactive reflexes. Monitor patients for the development of the signs and symptoms of opioid withdrawal.

Abrupt postoperative reversal of opioid depression after using naloxone hydrochloride may result in nausea, vomiting, sweating, tremulousness, tachycardia, hypotension, hypertension, seizures, ventricular tachycardia and fibrillation, pulmonary edema, and cardiac arrest. Death, coma, and encephalopathy have been reported as sequelae of these events. These events have primarily occurred in patients who had pre-existing cardiovascular disorders or received other drugs that may have similar adverse cardiovascular effects. Although a direct cause and effect relationship has not been established, after use of naloxone hydrochloride, monitor patients with pre-existing cardiac disease or patients who have received medications with potential adverse cardiovascular effects for hypotension, ventricular tachycardia or fibrillation, and pulmonary edema in an appropriate healthcare setting. It has been suggested that the pathogenesis of pulmonary edema associated with the use of naloxone hydrochloride is similar to neurogenic pulmonary edema, i.e., a centrally mediated massive catecholamine response leading to a dramatic shift of blood volume into the pulmonary vascular bed resulting in increased hydrostatic pressures.

6 ADVERSE REACTIONS

The following serious adverse reactions are discussed elsewhere in the labeling:

  • Precipitation of Severe Opioid Withdrawal [see Warnings and Precautions (5.3)]

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to the rates in the clinical studies of another drug and may not reflect the rates observed in practice.

The following adverse reactions were observed in NALOXONE AUTO-INJECTOR clinical studies. In two pharmacokinetic studies with a total of 54 healthy adult subjects exposed to 0.4 mg NALOXONE AUTO-INJECTOR, 0.8 mg NALOXONE AUTO-INJECTOR (two 0.4 mg NALOXONE AUTO-INJECTORS) or 2 mg NALOXONE AUTO-INJECTOR, adverse reactions occurring in more than one subject were dizziness and injection site erythema.

The following adverse reactions have been identified during post-approval use of naloxone hydrochloride in the post-operative setting. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: Hypotension, hypertension, ventricular tachycardia and fibrillation, dyspnea, pulmonary edema, and cardiac arrest. Death, coma, and encephalopathy have been reported as sequelae of these events. Excessive doses of naloxone hydrochloride in post-operative patients have resulted in significant reversal of analgesia and have caused agitation [see Warnings and Precautions (5.3)].

Other events that have been reported in post-marketing use of NALOXONE AUTO-INJECTOR include agitation, disorientation, confusion, and anger.

Abrupt reversal of opioid effects in persons who were physically dependent on opioids has precipitated an acute withdrawal syndrome. Signs and symptoms have included: body aches, fever, sweating, runny nose, sneezing, piloerection, yawning, weakness, shivering or trembling, nervousness, restlessness or irritability, diarrhea, nausea or vomiting, abdominal cramps, increased blood pressure, tachycardia. In the neonate, opioid withdrawal signs and symptoms also included: convulsions, excessive crying, hyperactive reflexes [see Warnings and Precautions (5.3)].

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Risk Summary

The limited available data on naloxone use in pregnant women are not sufficient to inform a drug-associated risk. However, there are risks to the fetus of the opioid-dependent mother with use of naloxone [see Clinical Considerations]. In animal reproduction studies, no embryotoxic or teratogenic effects were observed in mice and rats treated with naloxone hydrochloride during the period of organogenesis at doses equivalent to 4-times and 8-times, respectively, the dose of a 50 kg human given 10 mg [see Data].

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Clinical Considerations

Fetal/Neonatal adverse reactions

Naloxone hydrochloride crosses the placenta, and may precipitate withdrawal in the fetus as well as in the opioid-dependent mother [see Warnings and Precautions (5.3)]. The fetus should be evaluated for signs of distress after NALOXONE AUTO-INJECTOR is used. Careful monitoring is needed until the fetus and mother are stabilized.

Data

Animal Data

Naloxone hydrochloride was administered during organogenesis to mice and rats at doses 4-times and 8-times, respectively, the dose of 10 mg/day given to a 50 kg human (when based on body surface area or mg/m2). These studies demonstrated no embryotoxic or teratogenic effects due to naloxone hydrochloride.

8.2 Lactation

Risk Summary

There is no information regarding the presence of naloxone in human milk, or the effects of naloxone on the breastfed infant or on milk production. Studies in nursing mothers have shown that naloxone does not affect prolactin or oxytocin hormone levels. Naloxone is minimally orally bioavailable. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for NALOXONE AUTO-INJECTOR and any potential adverse effects on the breastfed infant from NALOXONE AUTO-INJECTOR or from the underlying maternal condition.

8.4 Pediatric Use

The safety and effectiveness of NALOXONE AUTO-INJECTOR (for intramuscular and subcutaneous use) have been established in pediatric patients of all ages for the emergency treatment of known or suspected opioid overdose. Use of naloxone hydrochloride in all pediatric patients is supported by adult bioequivalence studies coupled with evidence from the safe and effective use of another naloxone hydrochloride injectable product. No pediatric studies were conducted for NALOXONE AUTO-INJECTOR.

Absorption of naloxone hydrochloride following subcutaneous or intramuscular administration in pediatric patients may be erratic or delayed. Even when the opiate-intoxicated pediatric patient responds appropriately to naloxone hydrochloride injection, he/she must be carefully monitored for at least 24 hours as a relapse may occur as naloxone is metabolized.

In opioid-dependent pediatric patients, (including neonates), administration of naloxone hydrochloride may result in an abrupt and complete reversal of opioid effects, precipitating an acute opioid withdrawal syndrome. There may be clinical settings, particularly the postpartum period in neonates with known or suspected exposure to maternal opioid use, where it is preferable to avoid the abrupt precipitation of opioid withdrawal symptoms. Unlike acute opioid withdrawal in adults, acute opioid withdrawal in neonates manifesting as seizures may be life-threatening if not recognized and properly treated. Other signs and symptoms in neonates may include excessive crying and hyperactive reflexes. In these settings where it may be preferable to avoid the abrupt precipitation of acute opioid withdrawal symptoms, consider use of an alternative, naloxone hydrochloride product that can be dosed according to weight and titrated to effect. [see Warnings and Precautions (5.3)].

In pediatric patients under the age of one year, the caregiver should pinch the thigh muscle while administering NALOXONE AUTO-INJECTOR. Carefully observe the administration site for evidence of residual needle parts, signs of infection, or both. [see Dosing Information (2.2)].

8.5 Geriatric Use

Geriatric patients have a greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy. Therefore, the systemic exposure of naloxone can be higher in these patients.

Clinical studies of naloxone hydrochloride did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

11 DESCRIPTION

Naloxone hydrochloride injection auto-injector is a pre-filled, single-use auto-injector. NALOXONE AUTO-INJECTOR is not made with natural rubber latex. Chemically, naloxone hydrochloride is the hydrochloride salt of 17-Allyl-4,5α-epoxy-3,14-dihydroxymorphinan-6-one hydrochloride with the following structure:

Chemical Structure

C19H21NO4• HCl

M.W. 363.84

Naloxone hydrochloride occurs as a white to slightly off-white powder, and is soluble in water, in dilute acids, and in strong alkali; slightly soluble in alcohol; practically insoluble in ether and in chloroform.

Each 0.4 mL of NALOXONE AUTO-INJECTOR contains 2 mg naloxone hydrochloride, 3.34 mg of sodium chloride, hydrochloric acid to adjust pH, and water for injection. The pH range is 3.0 to 4.5.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Naloxone hydrochloride is an opioid antagonist that antagonizes opioid effects by competing for the same receptor sites.

Naloxone hydrochloride reverses the effects of opioids, including respiratory depression, sedation, and hypotension. Also, it can reverse the psychotomimetic and dysphoric effects of agonist-antagonists such as pentazocine.

12.2 Pharmacodynamics

When naloxone hydrochloride is administered intravenously, the onset of action is generally apparent within two minutes. The time to onset of action is shorter for intravenous compared to subcutaneous or intramuscular routes of administration.

The duration of action is dependent upon the dose and route of administration of naloxone hydrochloride.

12.3 Pharmacokinetics

In a pharmacokinetic study in 30 healthy subjects, a single 0.4 mg subcutaneous or intramuscular naloxone injection administered using NALOXONE AUTO-INJECTOR provides equivalent naloxone AUC and 15% greater naloxone Cmax in comparison to a single 0.4 mg subcutaneous or intramuscular naloxone injection administered using a standard syringe.

Following a single 0.4 mg NALOXONE AUTO-INJECTOR injection, the median Tmax of naloxone was reached at 0.25 hours (range 0.08 to 1.23 hours), with a mean Cmax value of 1.24 (51.4% CV) ng/mL. The mean plasma half-life of naloxone in healthy adults was 1.28 (38.0% CV) hours. In the same study, following administration of a single dose of 0.4 mg naloxone injection using a standard syringe, the median Tmax was 0.33 hours (range 0.08 to 2.03 hours) and the mean Cmax value was 1.07 (45.1% CV) ng/mL. The mean plasma half-life was 1.36 (23.5% CV) hours.

A second pharmacokinetic study in 24 healthy subjects using a crossover design, evaluated a single 0.4 mg NALOXONE AUTO-INJECTOR injection, a single 2 mg NALOXONE AUTO-INJECTOR injection, and two 0.4 mg NALOXONE AUTO-INJECTOR injections administered two minutes apart (0.8 mg naloxone hydrochloride total). The pharmacokinetic parameters obtained in this study are shown in Table 1 and the plasma concentration time profiles of naloxone are in Figure 1.

Distribution

Following parenteral administration, naloxone is distributed in the body and readily crosses the placenta. Plasma protein binding occurs but is relatively weak. Plasma albumin is the major binding constituent but significant binding of naloxone also occurs to plasma constituents other than albumin. It is not known whether naloxone is excreted into human milk.

Elimination

Following a single 0.4 mg NALOXONE AUTO-INJECTOR injection, the mean plasma half-life of naloxone in healthy adults was 1.58 (28.9% CV) hours and 1.53 (25% CV) hours following a single 2 mg NALOXONE AUTO-INJECTOR injection. In a neonatal study of naloxone injection, the mean (± SD) plasma half-life was observed to be 3.1 (± 0.5) hours.

Metabolism

Naloxone hydrochloride is metabolized in the liver, primarily by glucuronide conjugation with naloxone-3-glucoronide as the major metabolite.

Excretion

After an oral or intravenous dose, about 25-40% of naloxone is excreted as metabolites in urine within 6 hours, about 50% in 24 hours, and 60-70% in 72 hours.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis

Long-term animal studies to evaluate the carcinogenic potential of naloxone have not been completed.

Mutagenesis

Naloxone was weakly positive in the Ames mutagenicity and in the in vitro human lymphocyte chromosome aberration test but was negative in the in vitro Chinese hamster V79 cell HGPRT mutagenicity assay and in the in vivo rat bone marrow chromosome aberration study.

Impairment of Fertility

Reproduction studies conducted in mice and rats at doses 4-times and 8-times, respectively, the dose of a 50 kg human given 10 mg/day (when based on surface area or mg/m2), demonstrated no adverse effect of naloxone hydrochloride on fertility.

17 PATIENT COUNSELING INFORMATION

Advise the patient and family members or caregivers to read and become familiar with the FDA-approved patient labeling (Patient Information and Instructions for Use).

Instruct patients and their family members or caregivers to:

  • Become familiar with the following information contained in the carton as soon as they receive NALOXONE AUTO-INJECTOR:
    • NALOXONE AUTO-INJECTOR Instructions for Use
    • Trainer for EVZIO Instructions for Use
    • Trainer for EVZIO
  • Become familiar with the device labeling color scheme of NALOXONE AUTO-INJECTOR and the Trainer for EVZIO
    • The 2 mg dosage form of NALOXONE AUTO-INJECTOR is blue and purple.
    • The Trainer for EVZIO is black and white.
  • Practice using the Trainer before NALOXONE AUTO-INJECTOR is needed.
    • Each NALOXONE AUTO-INJECTOR can only be used one time; however, Trainer for EVZIO can be re-used for training purposes and its red safety guard can be removed and replaced.
    • Both NALOXONE AUTO-INJECTOR and Trainer for EVZIO incorporate the electronic voice instruction system.
  • It is recommended that patients and caregivers become familiar with the Trainer for EVZIO provided and read the Instructions for Use; however, untrained caregivers or family members should still attempt to use NALOXONE AUTO-INJECTOR during a suspected opioid overdose while awaiting definitive emergency medical care.

Recognition of Opioid Overdose

Instruct the patients and their family members or caregivers how to recognize the signs and symptoms of an opioid overdose requiring the use of NALOXONE AUTO-INJECTOR such as the following:

  • Extreme sleepiness - inability to awaken a patient verbally or upon a firm sternal rub.
  • Breathing problems - this can range from slow or shallow breathing to no breathing in a patient who cannot be awakened.
  • Other signs and symptoms that may accompany sleepiness and breathing problems include the following:
    • Extremely small pupils (the black circle in the center of the colored part of the eye) sometimes called “pinpoint pupils.”
    • Slow heartbeat and/or low blood pressure.

Risk of Recurrent Respiratory and Central Nervous System Depression

Instruct patients and their family members or caregivers that since the duration of action of most opioids may exceed that of NALOXONE AUTO-INJECTOR, they must seek immediate emergency medical assistance after the first dose of NALOXONE AUTO-INJECTOR and keep the patient under continued surveillance [see Dosage and Administration (2.2), Warnings and Precautions (5.3)].

Limited Efficacy for/with Partial Agonists or Mixed Agonist/Antagonists

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 and may require higher doses of naloxone hydrochloride or repeated administration of NALOXONE AUTO-INJECTOR [see Dosage and Administration (2.2), Warnings and Precautions (5.3)].

Precipitation of Severe Opioid Withdrawal

Instruct patients and their family members or caregivers that the use of NALOXONE AUTO-INJECTOR in patients who are opioid dependent may precipitate an acute abstinence syndrome characterized by the following signs and symptoms: body aches, diarrhea, tachycardia, fever, runny nose, sneezing, piloerection, sweating, yawning, nausea or vomiting, nervousness, restlessness or irritability, shivering or trembling, abdominal cramps, weakness, and increased blood pressure. In neonates, opioid withdrawal may be life threatening if not recognized and properly treated, and may include the following signs and symptoms: convulsions, excessive crying, and hyperactive reflexes [see Warnings and Precautions (5.3, Adverse Reactions (6)].

Administration Instructions

Instruct patients and their family members or caregivers about the following important information:

  • Make sure NALOXONE AUTO-INJECTOR is present whenever persons may be intentionally or accidentally exposed to an opioid to treat serious opioid overdose (i.e., opioid emergencies).
  • Administer NALOXONE AUTO-INJECTOR as quickly as possible if a patient is unresponsive and an opioid overdose is suspected, even when in doubt, because prolonged respiratory depression may result in damage to the central nervous system or death. NALOXONE AUTO-INJECTOR is not a substitute for emergency medical care [see Dosage and Administration (2.1)].
  • NALOXONE AUTO-INJECTOR is user actuated and may be administered through clothing [e.g., pants, jeans, etc.] if necessary.
  • Inject NALOXONE AUTO-INJECTOR while pressing into the anterolateral aspect of the thigh. In pediatric patients less than 1 year of age, pinch the thigh muscle while administering NALOXONE AUTO-INJECTOR.
  • Upon actuation, NALOXONE AUTO-INJECTOR automatically inserts the needle intramuscularly or subcutaneously, delivers the naloxone, and retracts the needle fully into its housing. The needle is not visible before, during, or after injection.
  • Each NALOXONE AUTO-INJECTOR can only be used one time.
  • If the electronic voice instruction system on NALOXONE AUTO-INJECTOR does not work properly, NALOXONE AUTO-INJECTOR will still deliver the intended dose of naloxone hydrochloride when used according to the printed instructions on its label.
  • The electronic voice instructions are independent of activating NALOXONE AUTO-INJECTOR and it is not necessary to wait for the voice instructions to be completed prior to moving to the next step in the injection process.
  • Post-injection, the black base locks in place, a red indicator appears in the viewing window and electronic visual and audible instructions signal that NALOXONE AUTO-INJECTOR has delivered the intended dose of naloxone hydrochloride.
  • NALOXONE AUTO-INJECTOR’s red safety guard should not be replaced under any circumstances. However, the Trainer is designed for re-use and its red safety guard can be removed and replaced.
  • Periodically visually inspect the naloxone solution through the viewing window. If the solution is discolored, cloudy, or contains solid particles, replace it with a new NALOXONE AUTO-INJECTOR.
  • Replace NALOXONE AUTO-INJECTOR before its expiration date.

What is the most important information I should know about Naloxone HCl Injection Auto-Injector?

Naloxone HCl Injection Auto-Injector (referred to throughout as NALOXONE AUTO-INJECTOR) is used to temporarily reverse the effects of opioid medicines. The medicine in NALOXONE AUTO-INJECTOR has no effect in people who are not taking opioid medicines. Always carry NALOXONE AUTO-INJECTOR with you in case of an opioid emergency.

  • Use NALOXONE AUTO-INJECTOR right away if you or your caregiver think signs or symptoms of an opioid emergency are present, even if you are not sure, because an opioid emergency can cause severe injury or death. Signs and symptoms of an opioid emergency may include:
    • unusual sleepiness and you are not able to awaken the person with a loud voice or rubbing firmly on the middle of their chest (sternum)
    • breathing problems including slow or shallow breathing in someone difficult to awaken or they look like they are not breathing
    • the black circle in the center of the colored part of the eye (pupil) is very small, sometimes called “pinpoint pupils” in someone difficult to awaken

  • Get emergency medical help right away after using the first dose of NALOXONE AUTO-INJECTOR. Rescue breathing or CPR (cardiopulmonary resuscitation) may be given while waiting for emergency medical help.
  • The signs and symptoms of an opioid emergency can return within several minutes after NALOXONE AUTO-INJECTOR is given. If this happens, give additional injections using a new NALOXONE AUTO-INJECTOR every 2 to 3 minutes and continue to closely watch the person until emergency help is received.

What is NALOXONE AUTO-INJECTOR?

  • NALOXONE AUTO-INJECTOR is a prescription medicine used in adults and children for the treatment of an opioid emergency such as an overdose or a possible opioid overdose with signs of breathing problems and severe sleepiness or not being able to respond.
