The purpose of this program is to expand access to naloxone and other Food and Drug Administration (FDA) approved overdose reversal medications for emergency treatment of known or suspected opioid overdose. The recipients will collaborate with other prescribers at the community level to implement trainings on policies, procedures, and models of care for prescribing, co-prescribing, and expanding access to naloxone and other FDA-approved overdose reversal medications to the specified population of focus (i.e., rural or urban).
