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.
By jeef on Sun, 11-07-10, 17:51. I hold on to my expired epipen because after I got it i have since lost insurance and any finances to get a new one. I do think epipens expire after time, however i also think that the expiration time that is set is not accurate. I have heard of expired pens working just fine. I think that they set the expiration date before it actually expires so they are able to sell more and make more money.
