The FDA has approved the opioid overdose drug Narcan to be sold over the counter. Narcan, a quick-acting naloxone nasal spray, could become available in pharmacies, as well as convenience stores and gas stations, by late summer. Opioid overdoses killed over 81,000 people in 2021. It’s not yet known how much manufacturer Emergent BioSolutions will charge for Narcan. Advocates are calling for the life-saving drug to be distributed for free.
