At age 15, I suddenly felt an unquenchable thirst and began urinating frequently. I lost 20 pounds. I had developed Type 1 diabetes, an autoimmune disease that destroyed my body’s ability to produce insulin. Without insulin, I would have eventually developed a condition called diabetic ketoacidosis, which is lethal without (and even sometimes with) treatment.

Years later, I’m a practicing endocrinologist. I could never have imagined back when I first started taking insulin that one day I would have so many patients who could not afford the medication because of skyrocketing prices. When the drug was discovered in 1921, the original patent was sold to the University of Toronto for $1 so that no one else could patent it and “secure a profitable monopoly.”

Numerous improvements later, insulin is produced by a three-company oligopoly. When the first of the newer insulin “analogs,” Humalog, hit the market in 1996, it sold for $21 a vial. Today, vials of analog insulins, including Humalog, sell for about $300 . Patients with Type 1 diabetes typically require two or three vials of insulin per month, but patients who are more resistant to insulin, such as those with Type 2 diabetes, may require six or more.
