Are low cost Epinepherine, Ana-Kits viable alternatives to expensive Epipens?

Thirty years ago you could buy an “Ana Kit” (sometimes called a “bee kit” or “insect bite kit”) that came with a simple, pre-loaded syringe that had steps in it so you had 2 doses if needed. The neat, flat, plastic container also included 2 antihistamine tablets and space for information and other meds if needed.
The system was simple and relatively inexpensive. There were no complicated spring-loaded pistons and triggers like in the current Epipen.
The kit was so cheap you did not mind tossing it when it expired.

To reduce costs, why isn’t there a manufacturer selling Ana Kits? Load the same epinephrine in simple syringes and charge less.

Does anyone here remember them? No one seems to be making them.
Are they available outside of the US?

If they were available here I’ll bet almost every Epipen user would switch.
(And Mylan Pharmaceuticals CEO, Heather Bresch, can donate the mountain of unsold Epipens while watching the stock plummet.)
