There are lots of patient assistance programs offered by manufacturers (depending on patient income levels) that will give patients free brand name meds. Perhaps along with the "therapeutic equivalent" option (which I really like) there could be information about available patient assistance programs?
All of them are stored on
www.rxassist.org
A major challenge with these is that they are continually updated. Maybe the best way to handle this would be to link to that website and automatically search for the medication if it wasn't found cheap generically...
great site!
