: Our son has had three seizures in the past year and a half. He has been on 400 mg of dilantin. This has just been increased to 600 mg a day. Is there a level at which Dilantin becomes ineffective or dangerous?
My prescription drug book says 600 mg. daily is the upper limit. You need to know what his blood level is. 10-20 is the therapeutic range. High blood levels can be very toxic and even increase seizures. He's at an extremely high dose!
