In-date medication comes back faster than it goes out
A resident is discharged, and the medication comes back sealed and in date.
It happens every cycle, across every facility you serve. Federal rules let you redispense some of it, but only with the documentation to back it up. The rest, still perfectly good, becomes waste you sort, log, and carry.
Another pharmacy needs that returned stock right now, and the trade carries DSCSA transaction records.
