HealthDay News — Three large drug makers have launched a legal challenge against the Trump administration’s rule requiring the prices of drugs to be included in television ads.

A lawsuit against the rule, set to take effect July 9, was filed Friday in federal court in Washington, D.C., by Merck, Eli Lilly, and Amgen, The New York Times reported. A trade group for advertisers is also part of the lawsuit.

The lawsuit contends that the rule is illegal because it violates the companies’ First Amendment rights and claims that the pricing information could mislead consumers because insurers often cover most of a drug’s cost, The Times reported.

The rule applies to any drug with a list price of more than $35 a month.
