Warning and untitled letters on broadcast and print DTC ads have plummeted since PhRMA's adoption of its Guiding Principles on DTC in August 2005.
In 2004, the FDA's Division of Drug Marketing, Advertising and Communications issued 13 warning and untitled letters on DTC ads. From January to August of 2005, the agency issued 17 warning and untitled letters on DTC ads. Since then, it has issued two—neither of which concerns broadcast or print, the media covered by PhRMA's voluntary code. “It reflects a significant change in attitude at DDMAC,” said John Kamp, executive director of the Coalition for Healthcare Communications.
