Physicians report on patient encounters involving direct-to-consumer advertising.

We surveyed a national sample of 643 physicians on events associated with visits during which patients discussed an advertised drug. Physicians perceived improved communication and education but also thought that direct-to-consumer advertising (DTCA) led patients to seek unnecessary treatments. Physicians prescribed the advertised drug in 39 percent of DTCA visits but also recommended lifestyle changes and suggested other treatments. Referring to visits when the DTCA drug was prescribed, 46 percent said that it was the most effective drug, and 48 percent said that others were equally effective. Prescribing DTCA drugs when other effective drugs are available warrants further study.
