Parent comment's being sloppy. Parent meant to say that there are generic EpiPen alternatives (epinephrine + delivery system) but there isn't a generic EpiPen (name brand delivery system). Mylan claims that EpiPen (injector) has superior features and is easier to use.

are on the injector device itself, not the medicine inside.
So, while you can’t get a generic EpiPen, there are
alternatives that use epinephrine."
