When Old Medicine Goes Bad (NPR)
On February 6, NPR's Morning Edition aired an informative piece about expiration dates. Please consider sharing this information with participants.
What does an "expiration" date on medicine really mean? Is the drug now dangerous? Less effective? That date stamped on the label actually means a lot. It's based on scientific evidence gathered by the manufacturer showing how long the drug's potency lasts. Exact potency may not be a big deal for treating a headache, but for fighting a bacterial infection with antibiotics, using less than fully potent drugs could fail to treat the infection and contribute to antibiotic resistance.
