Until now, treatments for drug overdoses have been entrusted to health professionals and police officers, but today the FDA approved the first drug delivery device made for civilians to administer an overdose antidote to victims. The device, called Evzio, is a credit-card sized dispenser that contains a needle, which is used to administer the antidote naloxone to someone who has suffered a drug overdose. The FDA describes the device working similarly to automated defibrillators: when turned on, Evzio gives the user verbal instructions on how to inject naloxone in a victim. However, the FDA does note that while naloxone does help counteract the effects of an overdose from opioids like heroin, it is not a substitute for medical care.
