"If an expired medication is for a minor health problem, for example, for a headache, hayfever, or mild pain, it may also be safe to take it, although drug potency might not be 100 percent. Research has shown many military stockpile medications retained 90 percent of their potency in their original stock bottle." -Drugs.com RE: Drug Expiration Dates.
