There is evidence that some medications may be safe to consume after the expiration date. Even though these may be safe to consume after the expiration date, the drugs may not be as effective due to decreased potency. Also, certain medications have very strict storage requirements and their expiration dates should be strictly followed. Medications that are liquid, like many children’s medications, should not be used past their expiration dates. Other medications that should not be used past their expiration dates include insulin, nitroglycerin, and antibiotics.
