Prices are outpacing inflation and insurance coverage is declining.

The cost of prescription drugs in the U.S. has surged nearly 40% over the past decade, easily outstripping the pace of inflation, according to a new study.

Findings published by GoodRx, a drug savings company, show that the list price for prescription drugs has climbed about 37% since 2014. Although price increases have slowed this year, costs continue to pose a "significant burden" to many consumers.

In 2024 alone, Americans have spent $21 billion on out-of-pocket prescriptions. That amounts to about $16.26 per person, according to the data.

"For most Americans, the difficulty with affordable medications isn’t over the ones that cost thousands of dollars," said Tori Marsh, director of GoodRx research. "It’s about affording routine drugs for chronic conditions, and finding that their insurance doesn’t cover what it used to."

Although health care is often covered by insurance, more of the cost burden is being shifted to consumers as prescription insurance coverage gets more complex and restrictive. These restrictions are what GoodRx dubbed the "big pinch" – insurance plans, both Medicare and commercial, are covering fewer medications and adding more restrictions on coverage.

About 54% of medications are covered by insurance, based on Medicare plans. Half of medications that are covered by Medicare have an insurance restriction, like step therapy or prior authorization. And at least one-quarter of Americans have a prescription that is not covered by insurance.

On top of that, the average deductible has nearly doubled over the past decade from $917 to $1,644.

"Despite various efforts by policymakers and pharmaceutical manufacturers to combat rising drug prices, the cost of medications remains a significant burden for many Americans," Marsh said. "Legislative attempts to cap insulin prices and manufacturer programs to provide discounts on expensive therapies have not led to a substantial decrease in overall drug costs."
