What is the initial naloxone nasal spray dose for suspected opioid overdose?

Explanation:
Naloxone works by competitively blocking opioid receptors, reversing the opioid-induced respiratory depression. The nasal spray form delivers a fixed dose per spray, and starting with a small, standard amount allows rapid reversal with minimal risk of withdrawal or overshoot. The initial dose is 0.4 mg per spray, given intranasally. If there’s inadequate improvement after 2–3 minutes, give another 0.4 mg spray and repeat as needed while monitoring breathing and consciousness. Doses like 2 mg or 1 mg per spray are higher than the typical starting amount, and 0.04 mg per spray is too small to reliably reverse overdose.
