Looking for help with pricey drugs

We have someone who is wondering if anyone knows of a program that might provide prescription assistance for individuals who have Narcolepsy? 

This request comes from someone who states they have searched for any type of prescription assistance program to help with Dextroamphetamine, Dexedrine or Dextrostate, but cannot find anything. Neither GlaskoSmithKline nor Amedra Pharmaceuticals offer a program for Dexedrine since it is offered in a generic form (Dextroamphetamine). Even though Dextroamphetamine is a generic drug, its price (even for this generic drug) is nearly $400.00 per month. 

Anyone with any ideas, please comment here or by email to midwestnarcolepsy@gmail.com
