Health worker Nathan Fields (left), Rep. Donna Edwards and Dr. Leana Wen show people how to use naloxone on a street corner in Sandtown, a Baltimore neighborhood where drug activity is common.
A kit with naloxone, also known by its brand name Narcan, is displayed at the South Jersey AIDS Alliance in Atlantic City. Naloxone counters an overdose with heroin or certain prescription painkillers by blocking the receptors these opioids bind to in the brain.
Tina Wolf demonstrates the use of naloxone to community members in Lindenhurst, N.Y., during an overdose prevention training. Georgia Dolan-Reilly (left) of the Suffolk County Prevention Resource Center helped with the training.
