Hi. There was a question about this in the past week but I can't find that thread.
I don't have a solid solution as it sounds like you have already investigated using coupon sites like GoodRX.
Here are some other thoughts for you:
-Ask about switching to generic, if you are using the brand name.
-Check out the drug makers site. Sometimes they have arrangements...
-Ask your pharmacist for help. I just picked up a non-ADHD script yesterday that with insurance was going to be $82. I happened to ask if he could make it cheaper and he figure out a way to make it $15. He found a coupon. Granted, I hadn't looked before I went to pick it up but....
Maybe you tried these, or maybe I gave you some ideas. I feel for you and wish you luck.
