From Star Tribune, Dec. 12: A bipartisan group of Minnesota legislators is considering regulations to rein in the soaring cost of insulin. With more than 460,000 diabetics in Minnesota, legislators say they are hearing many complaints from frustrated and worried constituents. A vial of insulin can cost between $300 and $400, and the more convenient insulin pens can cost nearly $700 for a box of five, with some patients using one box every week. But many pay different prices based on their insurance coverage, as well as co-payments and deductibles.
