Why does insulin cost so much the poor can’t afford it?
Greed. One vial of Novolin R costing $115 at Rite Aid can be bought over the counter at Walmart for $25. That's less than half the CO-PAY with my Medicare drug plan's online pharmacy.
I was on Metformin for 15 years. Tasted like ZEP industrial floor cleaner unless I swallowed it very quickly. Then I had to eat a substantial breakfast or I'd have heartburn all morning. Was never happier than the day I was allowed to get off it and start injecting insulin.
