Medical Editor: Jay W. Marks, MD. A couple of years ago an episode of the popular TV series Grey's Anatomy featured a woman with two uteruses (or uteri). This unusual condition does, in fact, occur as a result of abnormal fetal development.
Currently, EpiPens expire 18 months from date of manufacturing. Facing criticism for the drug's rapidly rising price, Bresch said the company hopes the expiration date can be extended to a minimum of 24 months.
Still, that doesnât mean that an EpiPen turns toxic or unusable the day after the date stamped on the box. Many doctors say, for example, that using an EpiPen thatâs expired by a few weeks or even a month or two is better than not treating someone who might be going into anaphylactic shock after an allergic reaction.
