When Medicare started paying 50% in the donut hole, The price of Insulin tripled, and there has been no reason except corporate rip-off. With all kinds of political raving about rising Medicare costs, there has been NOTHING done about this. And, companies trying to get into the market to provide an alternative at lower prices were bought out by the same drug companies so they could keep their prices higher. I can't say too much about this, cause my blood pressure goes up and I need more pills to keep it down. I bet my prescriptions at Walmart, because I can get refills just about anywhere we are at. (except New York).
