The FDA's own assessment, that DTC advertisements will give substantial advantages and don't seem to cause substantial damage, is in keeping with survey and different information. Direct-to-consumer advertisements seem to supply valuable info (including risk information); induce information-seeking (mainly from physicians); prompt patients to debate conditions not antecedently discussed; and generate vital, positive externalities as well as the likelihood of improved patient compliance with drug medical aid. the results of DTC advertisements on drug consumption and on health care have however to be assessed.
