Perhaps due to the Vioxx [3] and teen antidepressant [4] scandals, "the Food and Drug Administration is pelting drugmakers [5] with letters warning that they have run afoul of promotional regulations." Advertising Age writes that the FDA's actions are "threatening to tip the $4 billion direct-to-consumer industry [6] into a full-blown crisis." The FDA has warned nine companies so far in 2005, compared to 12 in 2004 and five in 2003. "DTC ads account for nearly a third of the advertising on the major broadcast network's nightly news programs," notes AdAge. "This is not a crackdown, it's enforcement," said Thomas Abrams, the head of FDA's Division of Drug Marketing, Advertising and Communication. "We're prepared to take whatever action necessary to stop misleading promotion."
