My mother just recently passed away from adrenal gland cancer, which caused similar side effects to Cushing's Syndrome.  She had to take a Rx called Metyrapone to control her high cortisol levels.  This Rx cost $5,700/month and luckily we were able to get a grant through the PAN Foundation to help with the cost.  We have over 600 pills left however, and would love to be able to donate this medication if possible.  I am not having any luck with the Drs Office, the PAN Foundation, the Pharmacy that issued the drug or local pharmacies.  I just believe there has to be a resource out there that would accept unused/unopened medication that would ultimately help someone who can't afford it.  
Any suggestions or recommendations?
