Now: The long debated issue is that tetracyclines including doxycycline become toxic after its expiration date due to the compounds breaking down and producing a waste. Department of Defense Shelf Life Extension Program. I've read on a few sources that tetracyclines were redesigned so as not to produce this hazardous waste. The FDA regularly tests the DODs expired doxycycline and extends the shelf life. After quite a bit of research I have concluded that doxycycline is safe to take at any time as long as it was stored in a cool and dry environment in its original packaging or pill bottle stuffed with cotton. For doxy specifically it states anywhere from 17-133 month extensions have been granted. In my research I came across an FDA sanctioned pamphlet that addresses using doxycycline to treat anthrax exposure. At the very bottom of the 2nd page it states that if you receive doxycycline that is expired, it's okay the FDA has approved it for use.

The only cite I could find was this one for tetracycline where a Darwin award contestant developed Fanconi syndrome after taking 4g(! ) of tetracycline over a 48hr period -- pills that she had let get wet and then dried out, then kept these deteriorated pills in a cardboard box for a year before using them again! The problem with drugs after there expiration date is that no one actually knows what happens to them. Here it says doxycycline hyclate is normally stable and doesn't break down. Expiration dates are normally set by what's called advanced stability testing, where they simulate how long a drug will last In the lab.

The initial case report, involving a form of the drug that is no longer used, was published in Annals of Internal Medicine in 1963.

A 2004 review of the literature on tetracycline and similar antimicrobials suggested that it might be difficult to determine when the kidney ailment is caused by such a drug.
