This just happened to me with my antidepressants.

The label was made, then zero updates for over two weeks, so I called and got them re-sent because I’m a miserable asshole. Then, three days after the new prescription got here (sent next-day), a flurry of dozens of updates came through that the original package was making the entire journey that day and even a time (a 1-hour window) it would be delivered to my mailbox which I have never seen before. I assume it was only done that way because it’s very obviously a bottle of pills and they realized they might have fucked up big time. Even the refrigerated self-injectable I tried just said “itll be here this day before this time”.
