Good article on exp dates. Most have heard that Doxy becomes toxic after exp date.....Air Force says maybe not.
quote: Only one report known to the medical community linked an old drug to human toxicity. A 1963 Journal of the American Medical Association article said degraded tetracycline caused kidney damage.
Even this study, though, has been challenged by other scientists. Mr. Flaherty says the Shelf Life program encountered no toxicity with tetracycline and typically found batches effective for more than two years beyond their expiration dates.

Expirations dates on everything are there to protect the seller/manufacturer and make you buy more of the product. They are more of a liability and marketing tool than anything else.
