I have been on Dilantin since I was 13, my last seizure was in 1993. My wife is worried about me being on this for so long as it is possible to cause liver damage. My thoughts are, I have my blood tested every 6/mos. and it always comes back ok. Is anyone else on Dilantin and having any issues. I am meeting with a neurologist on the 14 in Sioux Falls South Dakota and am kinda worried he may want to take me off of it. I have been seizure free for so long and my wife has never seen me have one nor my kids and I do not want them to see it. But let me know any thoughts about the Dilantin and side affects anyone may be experiencing.
