A decision from the FDA could save thousands of lives.
Regulators have approved a hand-held injector containing medication that can reverse heroin overdoses.
Called Evzio, the prescription device is like an epi-pen, which is used to treat severe allergy attacks.
It's injected into muscle, releasing a drug that stops heroin and other opioids from fatally slowing a person's breathing.
The kit costs about $60 and comes with two pre-filled syringes.
The device is described as "user friendly" and does not require any training.
