WASHINGTON — TV pitches for prescription drugs will soon include the price, giving consumers more information upfront as they make medication choices at a time when new drugs can carry anxiety-inducing prices.

Health and Human Services Secretary Alex Azar said Wednesday the Trump administration has finalized regulations requiring drug companies to disclose list prices of medications costing more than $35 for a month’s supply.

“What I say to the companies is if you think the cost of your drug will scare people from buying your drugs, then lower your prices,” Azar said. “Transparency for American patients is here.”

Drug companies responded that adding prices to their commercials could unintentionally harm patients.

“We are concerned that the administration’s rule requiring list prices in direct-to-consumer television advertising could be confusing for patients and may discourage them from seeking needed medical care,” said the Pharmaceutical Research and Manufacturers of America, the main trade group.

But one major firm — Johnson & Johnson, based in New Brunswick, New Jersey — has already started disclosing the cost of its blood thinner Xarelto in TV advertising. And polls indicate many patients are not taking their medications as prescribed because of cost.

Drug pricing details are expected to appear in text toward the end of commercials, when potential side effects are disclosed. TV viewers should notice the change later this year, perhaps as early as the summer.

The government is hoping that patients armed with prices will start discussing affordability with their doctors, and gradually that will put pressure on drugmakers to keep costs of brand-name drugs in check.
