My best friend has epilepsy. He has a part D Rx plan through his medicare disability. The Dr. he see's is a specialist and does not want him to take generic brand anti epileptic drugs. He takes Lamictal and Dilantan. He is also in a drug study and the mfg. of the study drug supplies this for him. No way can he pay for the Lamictial and Dilantin and his part D drug plan will not pay for it either.
