The price of the 100-year-old drug has more than tripled in the last two decades, forcing the nation’s diabetics to pay thousands of dollars a year for the life-saving medication.
Some people on private insurance pay hundreds of dollars monthly for the drug. For most Medicare beneficiaries, the average out-of-pocket cost per insulin prescription was $54 in 2020 — an increase of nearly 40% since 2007, a study released last month by the Kaiser Family Foundation found. Others live in one of 22 states where the copay for a 30-day supply has been capped between $25 to $100.
The cost has led some to use less insulin than their doctor prescribes or postpone paying for other medical care.
Only three manufacturers — Eli Lilly, Novo Nordisk and Sanofi — produce insulin, allowing those companies to control much of the market.
“They’ve been historically raising their list prices for their respective products in lockstep with one another,” Dr. Jing Luo, a professor of medicine at the University of Pittsburgh, said. “There hasn’t been a lot of pricing pressure.”
And making a generic drug for insulin hasn’t been easy, with new manufacturers having to clear regulatory hurdles and questions over how a generic drug should be categorized, Luo added. A generic insulin is slated to come on the market in 2024 at no more than $30 a vial, which could drive down some of the price.
