D.W.
For 8 years, I sold diabetes medications and know a lot about patient assistance programs, supply companies and how to help.
Feel free to contact me via a private message if you'd like to discuss more about the specifics of the products he is taking - oral vs. injectible, etc.
it depends on the medications, the insurance plan, the formulary benefit manager who determines what medications are covered at what level, what the complications are, if the products are available in combination form, etc.
There are a lot of programs and a lot of advice - just need to know where to find it.
Good luck!
