Organizations and individuals will inevitably have Narcan/naloxone expire when trying to saturate communities, and there's nothing to be ashamed of about it. It's unfortunate to see it thrown out or disposed of when it could still be useful in communities having greater need.
If you or your organization find yourselves in this position, please don't hesitate to contact us. We'd be more than happy to help you rehome your Narcan/naloxone.
At the Folding Chair Project, one of our proudest accomplishments is rehoming expired Narcan/naloxone.
