Most of these are for chronic conditions, where people are seeing their doctor on a fairly regular (once every few months) basis. And yeah, at least some patients absolutely do ask, &quot;hey, I heard about X, is that good for me?&quot;<p>There are of course also the extreme cases of specifically asking for a given prescription, but like the parent mentioned, just having a few patients persistently ask the doc about X is enough of a motivator to get the doctor to pay [marginally] more attention to the doctor-facing literature&#x2F;ads&#x2F;sales force.
