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.

Consumers' reports on the health effects of direct-to-consumer drug advertising.

We conducted a national telephone survey about health care experiences associated with direct-to-consumer advertising (DTCA) of prescription drugs. Among the 35 percent of our sample who had a physician visit during which DTCA was discussed, 25 percent received a new diagnosis, of which 43 percent were considered high priority according to authoritative sources. More than half also reported actions taken by their physician other than prescribing the advertised drug. Despite concerns about DTCA's negative consequences, we found no differences in health effects between patients who took advertised drugs and those who took other prescription drugs.
