Community care
Naloxone.
A medicine that can temporarily reverse opioid overdose. Emergency care is still essential.
Also known as Narcan. A name does not verify contents.
What it can and cannot do
Naloxone blocks opioid effects and can restore breathing after opioid overdose. It does not reverse every cause of unconsciousness or poisoning. If opioid exposure is possible, uncertainty should not stop its use.

After someone wakes
Naloxone can wear off before the opioid. Dangerous symptoms may return, so the person still needs emergency care. Continue watching breathing until responders arrive.
