FDA approvals are less influential on prescribing patterns than pharmaceutical sales marketers are, according to a study in Health Affairs. University of California and Harvard researchers examined the prescribing of antidepressants and antipsychotics by pediatricians and child and adolescent psychiatrists at thirty-one academic medical centers in five US states between 2006 and 2009. When the centers restricted visits by pharmaceutical sales representatives, prescriptions for both on-label and off-label uses of drugs that the reps typically were promoting dropped significantly. Conversely, use of non-promoted drugs in both categories increased. “Our results suggest that in these classes of drugs, detailing influences physician prescribing more than FDA approval does,” wrote the researchers.

  1. I think it’s all marketing cause I was given Zyprexa for insomnia instead of a much much better choice of an off label drug to sleep Seroquel. This was before the Zyprexa scandal hit the news. The doctors learn from the drug reps and have I would guess have mostly never taken the stuff so besides patent reports so how would they even know what they do ?
