How can you return them? I picked up a prescription for a relative once, ad it was the wrong one, but the pharmacy said they couldn't accept a return. Maybe states have different laws.
They have a converted former outside mailbox with a one way drop with a locked top and only the top pharmacists have a key to it.
The converted mailbox is insight of most pharmacists working at that station. It is inside and again in sight of most pharmacists and techs working.
A free clinic used to take unused drugs, and they stopped last year due to the potential liabilities.
