Insulin is not like other drugs. It's a natural hormone that controls our blood sugar levels - too high causes vision loss, confusion, nausea, and eventually, organ failure; too low leads to heart irregularities, mood swings, seizures, loss of consciousness. For most of us, our bodies produce insulin naturally. But for Type 1 diabetics, insulin comes in clear glass vials, handed over the pharmacy counter each month - if they can afford it. One vial of the insulin now costs $275 without health insurance. In 1923, the discoverers of insulin sold its patent for $1, hoping the low price would keep the essential treatment available to everyone who needed it. |
