Abstract: The present disclosure relates to systems, devices and methods for locating opioid antagonist products associated with an opioid related condition. According to one aspect, a mobile computing device for locating an opioid antagonist product generally includes one or more processors, memory, a display, a user interface, a global positioning system (GPS) antenna, and a wireless communication antenna. The one or more processors are configured to determine a location of the mobile computing device based on a global positioning system signal, receive an input from a user indicative of an opioid related condition and, in response to receiving the input, communicate with one or more wireless networks to determine a location of one or more opioid antagonist products located near the mobile computing device. The one or more processors are configured to display the determined location(s) of the opioid antagonist product(s) located near the mobile computing device on the display.
