Important Safety Information for REZENOPY™
REZENOPY™ (naloxone hydrochloride) Nasal Spray 10 mg 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 adult and pediatric patients. It is intended for immediate administration as emergency therapy in settings where opioids may be present and is not a substitute for emergency medical care.
Important Safety Information
- Contraindications: REZENOPY™ nasal spray is contraindicated in patients known to be hypersensitive to naloxone hydrochloride or to any of the other ingredients.
- Warnings and Precautions:
-
- Risk of Recurrent Respiratory and CNS Depression: Due to the duration of action of naloxone relative to the opioid, keep the patient under continued surveillance and administer additional doses as necessary while awaiting emergency medical assistance.
-
- Risk of Limited Efficacy with Partial Agonists or Mixed Agonists/Antagonists: Reversal of respiratory 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. In neonates, opioid withdrawal may be life-threatening if not recognized and properly treated. Monitor for the development of opioid withdrawal.
-
- Risk of Cardiovascular Effects: Abrupt postoperative reversal of opioid depression may result in adverse cardiovascular effects. These events have primarily occurred in patients who had pre-existing cardiovascular disorders or received other drugs that may have similar adverse cardiovascular 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 REZENOPY™ nasal spray clinical study: upper abdominal pain, nasopharyngitis, and dysgeusia.
