AbstractDirect to consumer advertising (DTCA) of prescription drugs has increased dramatically in the past two decades. The effect of this increase in advertising on the frequency of inappropriate prescribing is poorly understood, as are the factors that may underly inappropriate prescribing. A review of existing observational and experimental studies that address advertising-related prescription requests and contain some measure of prescription appropriateness demonstrate that DTCA increases prescription requests, increases the likelihood of prescription, and increases both appropriate and inappropriate prescribing. Patient expectations, insufficient information sharing, and patient satisfaction surveys are proposed contributors to potentially inappropriate prescribing in response to DTCA.
