FDA approves Narcan for over-the-counter sales, offering hope in opioid crisis.

The FDA has approved the sale of Narcan, an overdose-reversing drug, without a prescription, making it the first opioid treatment drug to be sold over the counter. Narcan will be available at pharmacies by late summer, and it is hoped that making it more widely available will help control the nationwide overdose crisis, which has been linked to more than 100,000 U.S. deaths a year. However, concerns remain about whether people who buy Narcan over-the-counter will know how to use it properly, and whether the drugmaker could stop producing it if it isn't profitable as an over-the-counter option.
