Description

11 DESCRIPTION Naloxone HCl Nasal Spray is a pre-filled, single dose intranasal spray. Chemically, naloxone hydrochloride is the hydrochloride salt of 17-Allyl-4,5α-epoxy-3,14-dihydroxymorphinan-6-one hydrochloride with the following structure: C19H21NO4●HCl M.W. 363.84 Naloxone hydrochloride, an opioid antagonist, 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 Naloxone HCl Nasal Spray contains a 4 mg single dose of naloxone hydrochloride (equivalent to 3.6 mg of naloxone) in a 0.1 mL (100 microliter) aqueous solution. Inactive ingredients include benzalkonium chloride (preservative), disodium ethylenediaminetetraacetate (chelating agent), sodium chloride, hydrochloric acid to adjust pH, and purified water. The pH range is 3.5 to 5.5. STRUCTURE

What Is Naloxone Hcl Used For?

1 INDICATIONS & USAGE Naloxone HCl Nasal Spray is indicated for the emergency treatment of known or suspected opioid overdose, as manifested by respiratory and/or central nervous system depression. Naloxone HCl Nasal Spray is intended for immediate administration as emergency therapy in settings where opioids may be present. Naloxone HCl Nasal Spray is not a substitute for emergency medical care. Limitations of Use: Restrict prescription of naloxone hydrochloride nasal spray 2 mg to opioid-dependent patients expected to be at risk for severe opioid withdrawal in situations where there is a low risk for accidental or intentional opioid exposure by household contacts.

Dosage and Administration

2 DOSAGE & ADMINISTRATION 2.1 Important Administration Instructions Naloxone HCl Nasal Spray is for intranasal use only. No additional device assembly is required. 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 HCl Nasal Spray 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 HCl Nasal Spray. Emphasize the following instructions to the patient or caregiver:

  • Administer Naloxone HCl Nasal Spray as quickly as possible because prolonged respiratory depression may result in damage to the central nervous system or death. 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 HCl Nasal Spray, 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 HCl Nasal Spray.
  • Additional doses of Naloxone HCl Nasal Spray may be required until emergency medical assistance becomes available.
  • Do not attempt to reuse Naloxone HCl Nasal Spray. Each Naloxone HCl Nasal Spray contains a single dose of naloxone and cannot be reused.
  • Re-administer Naloxone HCl Nasal Spray, using a new nasal spray, every 2 to 3 minutes if the patient does not respond or responds and then relapses into respiratory depression.
  • Administer Naloxone HCl Nasal Spray in alternate nostrils with each dose.
  • Administer Naloxone HCl Nasal Spray according to the printed instructions on the device label and the Instructions for Use.
  • Place the patient in the supine position. Prior to administration, be sure the device nozzle is inserted in either nostril of the patient, and provide support to the back of the neck to allow the head to tilt back. Do not prime or test the device prior to administration.
  • To administer the dose, press firmly on the device plunger.
  • Remove the device nozzle from the nostril after use.
  • Turn patient on their side as shown in the Instructions for Use and call for emergency medical assistance immediately after administration of the first dose of Naloxone HCl Nasal Spray. 2.2 Dosing in Adults and Pediatric Patients Initial Dosing The recommended initial dose of Naloxone HCl Nasal Spray in adults and pediatric patients is one spray delivered by intranasal administration into one nostril. Repeat Dosing Seek emergency medical assistance as soon as possible after administering the first dose of Naloxone HCl Nasal Spray. The requirement for repeat doses of Naloxone HCl Nasal Spray depends upon the amount, type, and route of...

  • Side Effects (Adverse Reactions)

    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 a naloxone hydrochloride nasal spray clinical study. In a pharmacokinetic study of 30 healthy adult volunteers exposed to one spray of naloxone hydrochloride nasal spray in one nostril or two sprays of naloxone hydrochloride nasal spray, one in each nostril, the most common adverse reactions were: increased blood pressure, constipation, toothache, muscle spasms, musculoskeletal pain, headache, nasal dryness, nasal edema, nasal congestion, nasal inflammation, rhinalgia, and xeroderma. The following adverse reactions have been identified primarily 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. 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 some patients, there may be aggressive behavior upon abrupt reversal of an opioid overdose. In the neonate, opioid withdrawal signs and symptoms also included convulsions, excessive crying, and hyperactive reflexes.

  • Contraindications

    4 CONTRAINDICATIONS Naloxone HCl Nasal Spray is contraindicated in patients known to be hypersensitive to naloxone hydrochloride or to any of the other ingredients.
