Both words describe the same medical emergency. The difference is consent and knowledge.
How Fentanyl Overdose Differs From Fentanyl Poisoning
An overdose is when someone knowingly takes an opioid and takes too much. A poisoning is when someone is exposed to fentanyl they did not know was there. Counterfeit pills made to look like oxycodone, Xanax, or Adderall are the leading source, and fentanyl also turns up in heroin, cocaine, and methamphetamine. Mixing is uneven, so one pill from a batch can be survivable and the next one lethal. This is a common and usually unintentional form of polysubstance use. Clinically the two look identical: slow or absent breathing, pinpoint pupils, unresponsiveness, blue or gray lips and fingertips, and a limp body.
Why Fentanyl Is More Dangerous Than Other Opioids
Fentanyl is 50 to 100 times stronger than morphine and roughly 50 times stronger than heroin. Two milligrams can kill someone without opioid tolerance. That is a few grains of salt. Because it is potent and cheap to produce, it has spread through the illicit supply, and because the effective doses are so small, ordinary mixing errors become fatal ones.
What To Do If You Suspect Fentanyl Exposure
Call 911 first. Do not wait to see whether the person wakes up. Give Narcan if you have it, sprayed into one nostril, and start rescue breathing while you wait. Narcan cannot harm someone who has not taken opioids, so give it even when you are not sure opioids are involved. If there is no response within two to three minutes, give another dose. Fentanyl often needs more than one, because a single dose can wear off before the drug has cleared. Stay with the person. Breathing can stop again after they appear to recover. Good Samaritan laws in most places protect people who call for help. Anyone who survives a fentanyl overdose still needs hospital monitoring, even if they look fine, because respiratory depression can return hours later.
