Which part of the body is Narcan administered to block or reverse the side effects of opioid medications?

Narcan, also known as naloxone, is primarily administered as an intramuscular injection, often given in the outer thigh. This route allows for rapid absorption into the bloodstream, making it effective in reversing the effects of opioid overdoses. The outer thigh is a large muscle that provides easy access for administration, especially in emergency situations where immediate action is required to counteract the respiratory depression caused by opioids.

While there are other methods of administration for Narcan, such as intranasal or intravenous, the commonly recognized teaching emphasizes the intramuscular route for its accessibility and effectiveness in a wide range of settings, including community use.
