The drug-overdose antidote Narcan recently received Food and Drug Administration-approval for over-the-counter use.

EMTs say whatever happens after administering that first dose, the person who has overdosed will need medical care.

Nearly every state in the U.S. allows pharmacists or other qualified organizations to provided Narcan without a prescription to those at risk of an overdose. Making it available over the counter is meant to make it easier for people to access the opioid antidote.

Narcan's manufacturer says customers can expect the drug to be widely available in stores by late summer.
