Some drugs remain effective well beyond expiration date:
"Twelve of 14 compounds analyzed met government requirements for potency
up to 40 years after the drugs' expiration dates, according to a study
published in the Archives of Internal Medicine. Requiring drug makers to base
expiration dates on long-term stability tests could save consumers money and
help alleviate drug shortages, said researcher Lee Cantrell. However, the
findings do not mean that ALL drugs are safe or effective past their expiration
Saving money, alleviating drug shortages-I suspect the above information is not music to ears of many Pharmaceutical companies!
