Insulin prices have been rising — increases that mean some people are spending as much on monthly diabetes-related expenses as their mortgage payment.
It's led some people living with diabetes to turn to the black market, crowdfunding pages, and Facebook pages to get access to the life-saving drug.
At the same time, the companies that make insulin have faced pressure from politicians including Senator Bernie Sanders, class-action lawsuits that accuse the companies of price-fixing, and proposed legislation in Nevada.
Even in the face of this criticism, two of those drugmakers — Eli Lilly and Novo Nordisk — raised the list price of their insulins again in 2017.
Diabetes is a group of conditions in which the body can't properly regulate blood sugar that affects roughly 30 million people in the US. For many people living with diabetes — including the 1.25 million people in the US who have type-1 diabetes — injecting insulin is part of the daily routine.
