Where is the incentive for the reps to get doctors to write DAW1 or just to educate them about V over gV?
A doc can right DAW1 on a rx. It can't hurt and might help but that does not change the PA requirements, it does not change the Tier, it will likely increase the price the patient pays and the insurer does not have to honor the DAW without a proven explanation that the generic created a substantial risk for the patient. It is not an automatic V fill by any means.
So, if you have reps in an area where GV is the predominant med that is filled to penalize them for a GV rx makes no sense even as they may have educated the doc on V vs GV already and convinced them to prescribe V. I guess you could just stop having reps in that area if it not productive for V.
