Final answer:
A standing order from the Department of Health...for an overdose.
Step-by-step explanation:
A standing order from the Department of Health or a prescription/standing order from a physician pursuant to the Overdose Prevention Act can both be used to ensure access to overdose-reversal drugs like Naloxone.
The Department of Health may issue a standing order that allows certain organizations or individuals to distribute Naloxone without a specific prescription, while a physician can write a standing order for a patient to have Naloxone on hand in case of an overdose.
