What Is an Overdose Spray
An overdose spray is a nasal or oral device designed to deliver a measured dose of medication quickly. It is most commonly associated with naloxone, a treatment for opioid overdose. The spray form allows non-medical users to administer the drug without needles.
How Overdose Spray Works
When sprayed into the nose or mouth, the liquid is absorbed through the mucous membranes. Naloxone then blocks opioid receptors in the brain, temporarily reversing overdose symptoms such as slowed breathing and unconsciousness. Effects typically begin within minutes.
When and Where Overdose Spray Is Used
Overdose spray is used in emergency situations where opioid overdose is suspected. It is carried by first responders, community programs, and individuals at risk or their loved ones. Public health agencies recommend keeping the spray accessible and knowing basic response steps.
