What is the primary purpose of naloxone in the field?

• A. Reverses opioid-induced respiratory depression
• B. Treats non-opioid overdose
• C. Relieves chest pain
• D. Lowers fever

Answer: (A)

Naloxone works by acting as an opioid receptor antagonist, reversing the brain’s suppressed drive to breathe caused by opioid drugs. In an opioid overdose, opioids bind to receptors and depress respiration; naloxone competes for those same receptors and displaces the opioids, rapidly restoring breathing. In the field, the primary goal is to quickly revive ventilation and prevent hypoxia, so naloxone is given to promptly reverse the life-threatening respiratory depression. It can be given by nasal spray or intramuscular injection, and improvement in breathing typically occurs within minutes. Because naloxone’s effects may wear off before the opioid, patients may need repeat doses and continuous monitoring. This medication does not reverse non-opioid overdoses, is not used to treat chest pain, and does not lower fever.
