I'm fairly sure that you are right; I seem to vaguely remember something about that. If I' not mistaken, the manufacturers apply much shorter than necessary expiry dates on the drug lots. I haven't personally heard of anyone getting sick from degradated doxycycline (Vibramycin™), though.
When I started in pharmacy the Canadian government had just passed a law requiring drug companies to add expiration dates to seemingly anything that can be ingested. This is why table salt has an expiry date; so does most bottled water.
