Switch to a newer medication????? Long time user (30 years) of dilantin to control grand mal seizures. Dilantin works great controlling my siezures. Although, recently concerned with side effects. just had a scan that shows bone density loss, also, although can't really be sure, but I think I am a bit sapped of energy (who knows - been on it so long might have adjusted and this just seems normal???) Have not had gum issues (good oral health and routine probably a contributor to that). Hair? Hard to tell really, nothing really out of the ordinary. Did have some high liver enzyme levels that caused me some pain (not physical) in obtaining life insurance - but letters from doc helped that to be mitigated. So, bottom line - i want to switch - feel I need to switch - am scared to switch - if there is anyone else who is this same situation - would love to hear of your experience, decisions, and dterminants, etc. I really really really want to switch to a newer medication - but am scared to death that it won't work. I have been seizure free 21 years (and that was only because we tried to come off the medicine completely). Agonizing decision!
