A lot of these medicines that require patients to inject themselves come in a self administrating auto-injector. There are really simple to use, I mean literally anyone can inject themselves, then throw the one-use auto-injector out.

There's also needle guides[1] which provide a lot of flexibility for those who self-administer.
