Opioid overdoses can, and do, happen just about anywhere, from schools to public parks, from homes to workplaces, restaurants, and night clubs. Narcan (naloxone) is a drug that can be used to halt an overdose, and it’s increasingly being used to save lives by people other than police, first responders, or emergency room staff. In fact, the demand for Narcan is such that Walgreens will now be stocking the treatment and selling it over-the-counter at its pharmacies.

Walgreens currently offers naloxone without requiring a prescription in 45 states, and says it’s “eager and willing” to work with the other five states to make naloxone easier to get.
