I have found during one episode of unemployment that a couple of the manufacturers of insulin have programs to help with the cost of insulin. I think the assistance program from the makers of Lantus had the best program. They would help you get boxes of Lantus for free. You had to sign up for the program on the Lanus website.
I know that NovoNordisc has a program that will help to reduce your insurance copay by about 50%. Again signup is on the NovoNordisc website.

I don’t know if GoodRx has programs for other countries, but here in the United States it does help
