Expired Drugs Probably Aren't

All those medications have expiry dates. Did you ever wonder what they mean?

They  mean that during the approval process someone showed that the drug could last this long without degradation. If the drug is manufactured in 1990 and in 1992 it was tested and it contained enough of the drug, the U.S. FDA will allow the manufacturer to claim a two year shelf life. It does not mean that anyone ever showed any drug degradation after two years.

That test is rarely done. When it is performed, tests regularly show shelf lives of four years beyond the advertised life. What's more, even if the drug decays, that is not evidence that it has become harmful. The two doctors in this article (Cantrell and Clancy) have never heard or read “of anyone being harmed by any expired drugs”.

I Could Outrun a T-Rex

Two studies say that the Tyranasaurus Rex could not have been the fiercely fast predator shown in Jurassic Park. One says he would have run out of energy before he got up to speed. The other says his bones were not strong enough to handle the weight at high speeds.
