INDIAN WELLS, Calif. -- Naloxone, a medication known as the “overdose antidote,” can reverse the effects of an overdose from opioid drugs like heroin, Vicodin, OxyContin and morphine. Although Naloxone has saved tens of thousands of lives, and has been approved for use against drug overdose by the Food and Drug Administration since 1971, it's typically only administered by medical professionals. That began to change last April, when the FDA fast-tracked the approval of a device called Evzio.
