### Human:\nhow long are epi pens good for. my dad's doc says as long as the epi pen is still sealed it is still good. the epi pen is from 2007.\n\n### Assistant: it has expired long ago. don't use it. these are supposed to have at least a one year life based on the printed expiration date so always check the expiration date. get a new epipen prescription and make sure it does not expire in a few months. if it does refuse the prescription and ask for one that has a longer date.
