Part 3 portrays three different scenarios that could arise when a patient asks a pharmacist for advice on NARCAN® Nasal Spray.
NARCAN® NASAL SPRAY INDICATIONS AND IMPORTANT SAFETY INFORMATION
NARCAN® (naloxone hydrochloride) Nasal Spray 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. NARCAN® Nasal Spray is intended for immediate administration as
emergency therapy in settings where opioids may be present. NARCAN® Nasal Spray is a not a substitute for emergency medical care.
Important Safety Information
NARCAN® Nasal Spray is contraindicated in patients known to be hypersensitive to naloxone hydrochloride or to any of the other ingredients.
Seek emergency medical assistance immediately after initial use, keeping the patient under continued surveillance.
Risk of Recurrent Respiratory and CNS Depression: Due to the duration of action relative to the opioid, keep the patient under
continued surveillance and administer repeat doses of naloxone using a new nasal spray with each dose, as necessary, while awaiting emergency medical assistance.
Risk of Limited Efficacy with Partial Agonists or Mixed Agonists/Antagonists: Reversal of repiratory depression caused by partial
agonists or mixed agonists/antagonists, such as buprenorphine and pentazocine, may be incomplete. Larger or repeat doses may be required.
Precipitation of Severe Opioid Withdrawal: Use in patients who are opioid dependent may precipitate opioid withdrawal characterized
by 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, and tachycardia. In some patients, there may be aggressive behavior upon abrupt reversal of an opioid overdose.
In neonates, opioid withdrawal may be life-threatening if not recognized and properly treated and may also include convulsions, excessive crying, and hyperactive reflexes.
Monitor for the development of opioid withdrawal.
Risk of Cardiovascular (CV) Effects: Abrupt postoperative reversal of opioid depression may result in adverse CV effects. These events have primarily
occurred in patients who had pre-existing CV disorders or received other drugs that may have similar adverse CV effects. Monitor these patients closely in an appropriate healthcare setting
after use of naloxone hydrochloride.
Adverse Reactions: The following adverse reactions were observed in a NARCAN® Nasal Spray clinical study: increased blood pressure,
constipation, toothache, muscle spasms, musculoskeletal pain, headache, nasal dryness, nasal edema, nasal congestion, nasal inflammation, rhinalgia, and xerodermia.
