Naloxone is a medication that can rapidly reverse the effects of opioid overdose, including life-threatening respiratory depression (slow or stopped breathing). It works by binding to the same receptors in the brain that opioids like heroin, fentanyl, and prescription painkillers bind to, effectively reversing the overdose and restoring normal breathing.
Naloxone is often used in emergency situations, such as by first responders or family members of individuals at risk for opioid overdose. It can be administered via injection or as a nasal spray (brand name Narcan). It’s a crucial tool in combating the opioid crisis because it can save lives during an overdose, but it’s important to note that its effects may wear off before the opioids have fully cleared the system, so emergency medical care is still necessary after administration.
