​​Walgreens said Wednesday that it will sell its own generic version of over-the-counter Narcan, the lifesaving opioid overdose reversal drug that first rolled out to drugstore shelves last fall.

Its version of the antidote, a drug called naloxone, will cost $34.99 for two doses, $10 cheaper than the brandname version from Emergent BioSolutions that’s also sold at Walgreens and other major pharmacy chains across the U.S.

Walgreens’ generic version will be available on store shelves nationwide by the end of the month, the company said. It is already available to buy online.

Dr. Priya Mammen, senior medical director in the Walgreens Office of Clinical Integrity, said the company decided to launch a lower-priced option to increase access to the medication.

Drug overdoses are the leading cause of accidental death in the United States, according to the Centers for Disease Control and Prevention, killing nearly 107,000 people in 2021.
