Narcan administration by the EMT is indicated for:

• A. Stimulant overdoses
• B. Opioid overdoses
• C. Alcohol overdoses
• D. Non-opioid overdoses

Answer: (B)

Narcan is used because it blocks opioid receptors and reverses the life-threatening effects of opioid overdose, especially the dangerous slowing or stopping of breathing. When opioids bind to receptors, they depress respiratory drive and can dull consciousness. Naloxone competes for those same receptors and displaces the opioids, restoring normal breathing and alertness. Other substances—stimulants, alcohol, or non-opioid drugs—do not act primarily on opioid receptors, so reversing those effects with naloxone won’t be effective, which is why these overdoses aren’t indicated for Narcan. In practice, administer intranasal naloxone to a suspected opioid overdose with respiratory depression or reduced level of consciousness, and monitor closely as breathing improves or as withdrawal symptoms may occur in opioid-dependent patients. If there’s no improvement after a dose, follow protocol for repeating doses and continuing supportive care.
