How much Naloxone (Narcan) does your state need to save lives?
This interactive website is a tool to help explore how much naloxone (Narcan) a state may need to save lives,
either by averting the maximum number of deaths or by boosting the chances that naloxone will be on hand in a witnessed overdose.
The information was calculated by a mathematical model, so these numbers are estimates generated by the best available data at the time.
Naloxone need per year varies by geography and the type of epidemic that a place is experiencing.
How a state chooses to provide naloxone (through community programmes, initiated in a pharmacy, or prescribed by a provider)
in a community affects how much naloxone is needed. Select a state to get started.
Note, the data and model projections are based on 2017 data.
The epidemic classification for a given state may have since changed, for instance, shifting to a fentanyl epidemic.

Estimating Naloxone Need in the United States Across Fentanyl, Heroin, and Prescription Opioid Epidemics:
A Modelling Study Lancet Public Health, 2022.
The plots for each naloxone source vary that source, with the other sources kept constant at their current (2017) level.
Most states distribute more community-based kits than prescriber-based kits. So in the prescriber-based plot,
many states already have a high probability of naloxone use in a witnessed overdose due to their existing community-based naloxone kit distribution efforts.
