Direct-to-consumer advertising (DTC advertising) sometimes refers to the marketing of pharmaceutical products but applies in other areas as well. This form of advertising is directed toward patients, rather than healthcare professionals. The Food and Drug Administration is responsible for regulating DTC advertising in the United States. The FDA’s latest version of guidelines, though still in draft form, for pharmaceutical drug advertising was updated in 2009. Forms of DTC advertising include TV, print, radio and other mass and social media. There are ethical and regulatory concerns regarding DTC advertising, specifically the extent to which these ads may unduly influence the prescribing of the prescription medicines based on consumer demands when, in some cases, they may not be medically necessary.
