What is the reversal agent for an opioid overdose?

Naloxone reverses opioid overdoses by competing for and displacing opioids at brain receptors, quickly reversing respiratory depression and altered mental status. It binds to mu, kappa, and delta receptors, blocking the effects of opioids such as heroin, fentanyl, or prescription pain medicines. In the field, it’s commonly given as Narcan, and its rapid onset can restore breathing within minutes. Because many opioids can outlast naloxone, patients may require repeated doses or monitoring for re-narcotization after reversal. Activated charcoal is used to limit absorption after certain ingestions but isn’t a reversal for opioids. Flumazenil reverses benzodiazepines, not opioids. N-acetylcysteine treats acetaminophen overdose and has other uses but does not reverse opioid effects.
