Why strip and carton expiry dates should always match
A mismatched expiry between the strip and the carton is one of the strongest counterfeit signals. Here's how to spot it.

Legitimate manufacturers print the same batch number, manufacturing date and expiry date on both the strip and the outer carton.
When the dates don't match
- Possible repackaging of expired stock
- Counterfeit pack assembled from leftover strips
- Printing error — still a reason to return the pack
What to do
Return the medicine, ask the pharmacist to log the batch number, and report it to the state FDA if the pharmacy is dismissive.
