The number of Americans who believe prescription drug costs are “unreasonable” is on the rise, a new survey has found.

The Henry J. Kaiser Family Foundation has released the findings from a survey it conducted earlier this month. It should be noted that while the foundation regularly surveys public opinion on healthcare-related issues, this particular study was motivated by the recent Mylan EpiPen price hike controversy.

Of the 1,204 American adults who responded in the study, 77 percent believe prescription drug costs are unreasonable, up from 72 percent last year. Another 26 percent said they struggle to pay for their medicine.

“There is widespread support for a variety of actions in order to keep costs down” the study authors wrote

Such actions include allowing the feds to negotiate lower drug prices for Medicare recipients and an outright price cap on the more costly pharmaceutical products.

“Costs could be one reason why the share of Americans who say prescription drugs have made the lives of people in the U.S. better is declining,” the authors wrote.

Mylan CEO Heather Bresch recently stated that the company’s decision to increase the EpiPen price from $100 to $608 over the last decade was “fair,” due to the fact that patients are now responsible for wholesale health insurance costs.

The decision was reminiscent for many of the 2015 controversy wherein Martin “Pharma Bro” Shkreli of Turing Pharmaceuticals raised the price of the life-saving drug Daraprim from $13.50 per pill to $750.
