Indications and Clinical Use

NARCAN® Nasal Spray is a pure opioid antagonist indicated for emergency use outside of a hospital to reverse known or suspected opioid overdose, as manifested by respiratory and/or severe central nervous system depression.

NARCAN® Nasal Spray can be administered by a bystander (non-healthcare professional) before emergency medical assistance becomes available, but it is not intended to be a substitute for professional medical care. Emergency medical assistance (calling 911) should be requested immediately when an opioid overdose is suspected, before administering naloxone.


  • Patients who are hypersensitive to this drug or to any ingredient in the formulation or component of the container.

Most Serious Warnings & Precautions

  • Emergency medical assistance (calling 911) should be requested immediately when an opioid overdose is suspected, before using naloxone.
  • Individuals with a satisfactory response to an initial dose of naloxone should be kept under continued surveillance.
  • Caregivers administering naloxone should be prepared to act in response to or assist the patient in cases of potential adverse reactions such as aggressive reactions, convulsions and vomiting. Special attention is warranted if naloxone is administered to a neonate or a pregnant woman.

Other Relevant Warnings and Precautions

  • In opioid dependent people, naloxone may trigger an acute opioid withdrawal syndrome
  • Rebound opioid toxicity, including respiratory depression, following the temporary reversal of the opioid overdose
  • Not effective against respiratory depression due to non-opioid drugs
  • Rare cases of cardiac arrest, tachycardia and ventricular fibrillation
  • Post-operative consideration: instances of hypotension, hypertension, ventricular tachycardia and fibrillation, dyspnea, pulmonary edema and rare cases of cardiac arrest have been reported. Death, coma, and encephalopathy have been reported as sequelae of these events
  • Rare cases of convulsions or seizures
  • Irritability and aggressive behaviour
  • Gastrointestinal reactions including diarrhea, nausea, vomiting and abdominal cramps
  • Use in nursing women has not been established
