Walgreens on Wednesday said it will offer its own cheaper version of the over-the-counter opioid overdose reversal spray naloxone. The company said it will sell a two-dose pack of "Walgreens Brand Naloxone" for $34.99. That's around $10 cheaper than the over-the-counter branded drug Narcan, which became the first prescription-free version of naloxone to win Food and Drug Administration approval last year. The company said the launch of its prescription-free naloxone nasal spray comes after the FDA's recent approval of the product. Mammen hopes that Walgreens can help reduce the stigma associated with drug overdoses and naloxone use.
