Why are there so many near-identical labels from repackagers?
Because federal rules make each registered firm that repacks or relabels a drug list that drug with the FDA and submit its labeling. The same label text can then appear under several firms. We can't say repackager labels have more errors, but copied text carries any wrong word it already has, so the same slip can show up in more than one place.

What repackers and relabelers do
The FDA's rules define repacking as taking a finished drug out of the container it was sold in and putting it into a different container, without changing the drug. A relabeler is a firm that relabels a drug. Under 21 CFR 207.41, each registered firm must list each drug it manufactures, repacks, relabels or salvages for commercial distribution, and 21 CFR 207.49 says what labeling goes with that listing.
Why wrong words travel
Repacked and relabeled products usually carry text that started somewhere else. That's efficient, and it means:
- A wrong word in the source text comes along with every copy.
- Retyping or reformatting for a new layout is another chance to introduce one.
- A fix at the source doesn't reach copies that were already made.
This is the same template problem any labeling team has. See found a wrong word on a released label for why you fix the source first.
What to do if you repack or relabel
Read the high-stakes lines of the text you receive for meaning, not only against the master, because a matching copy of a wrong word still matches. See compare-to-master vs read for meaning and examples on the case index.

FAQ
Why do repackager labels look almost identical to the original?
Repackers and relabelers must list each drug with the FDA and submit its labeling, and their text usually comes from the original.
Do repackager labels have more errors?
We can't say that. What is true is that copied text carries any wrong word it already has.
Does matching the master catch a copied wrong word?
No. If the master has the wrong word, a matching copy has it too, so the line still needs a read for meaning.
