Nexavar....what to do??

My father passed away Feb. of this year from a combination of liver cancer and fatty liver disease. Not only did I lose a great mentor but also a good friend. Mom is taking things one day at a time and is having some financial difficulties. Dad was about to begin Nexavar but never did. I have two, 200mg, 120ct, bottles of this medication. I know this medication is very expensive and would like to somehow get mom some money. Is it wrong to pursue trying to sell this medicine privatley?? How would I go about it??? Could I be helping somebody who can't afford this med?? Just thinking out loud.
