Does narcan work on overdose of Fentanyl patches?

Yes, Narcan (naloxone) can be effective in reversing an overdose from fentanyl, including that from fentanyl patches. However, because fentanyl is a potent opioid, multiple doses of Narcan may be necessary to counteract the effects. It's crucial to seek emergency medical help immediately in any overdose situation, as professional intervention is often required.
