I have a LOT of unused packets of Cambia (16) and packages of Trokendi XR (3 30-day supply packages of 50 mg and 1.5 packages of 25 mg). I weaned myself off of both. I know I can dispose of them at Rx collection days but I hate to see all that new in package medication go to waste - does anyone know if there's a buyback or return program from the vendor?
