Lilly says the net price for its Humalog insulin—the price after discounts and rebates—fell to an average of $135 a patient a month in 2018, from $147 in 2014. During the same period, the product’s average list price rose 51.9% to $594 per patient monthly.
Lilly hasn’t raised the U.S. list price for Humalog since May 2017. U.S. sales of the drug rose 4% to $1.79 billion in 2018, which Lilly said was primarily driven by demand.
