That article provides pretty strong evidence that DTC ads, overall, are bad for patients:
58 percent [of physicians surveyed] agreed strongly that DTC ads make the drugs seem better than they really are.
Physicians thought the ads did not convey information about risks and benefits equally well. Seventy-eight percent of physicians believe their patients understand the possible benefits of the drug very well or somewhat, compared to 40 percent who believe their patients understand the possible risks, and 65 percent believe DTC ads confuse patients about the relative risks and benefits of prescription drugs. In addition, about 75 percent of physicians surveyed believed that DTC ads cause patients to think that the drug works better than it does, and many physicians felt some pressure to prescribe something when patients mentioned DTC ads.
Eight percent of physicians said they felt very pressured to prescribe the specific brand-name drug when asked.
Doctors believe that patients understand that they need to consult a health care professional about appropriate treatment. Eighty-two percent responded either "very well" or "somewhat" when asked whether they believe that their patients understand that only a doctor can decide whether a drug is right for them.
Note the last point means that 18% of the doctors believed that their patients thought they knew better than the doctor about whether or not a drug is right for them.
The few positive aspects, about patients being better informed about drug therapies that might help them, could be solved by making the monthly journal info I described available online. People go to Google and type in their symptoms and/or the name of their disease if they know it, and end up on sites like drugs.com and webmd.com. If Google were indexing the journal I described, and those other sites pulled from it too (publishing license should allow that, as it would be publicly funded), then patients would see all of the good information about the drugs, without the advertising bias.
