The U.S. Food and Drug Administration ( FDA) now requires TV and radio drug ads to be clearer and more direct. The new guidelines, which have been over 15 years in the making, are designed to end industry practices that downplay or distract viewers from risk information.

The new rules, which cover both TV and radio, instruct drugmakers to use simple, consumer-friendly language when describing their drugs, without medical jargon, distracting visuals or audio effects. A 2007 law directed the FDA to ensure that drug risk information appears “in a clear, conspicuous and neutral manner.”

Clear descriptions of potential risks and side effects will be required under rules that go into effect Nov. 20, even as the Trump administration readies an offensive against big pharma.
