... question. Because I have been on Dilantin for so long & its worked great have any of you changed to another seizure med that works just as well? I take the 100mg casules but something strange happened, I refilled my prescrition at least 4 months ago and noticed not only did the price drop but the label @the bottom said phenytoin not Dilantin. Yet the actual label says Dilantin 100mg. Anyone had this happen?
