Does the longer going without a seizure mean you are going to have one soon its been 15 years since my last dilantin level always been 3.2 no higher?

Not really: If seizures are well-managed it does not mean one is just around the corner. No indivudal advice can be given here, but there is brain maturation which occurs which should also help reduce seizure threshold if seizures were of childhood or adolescent onset. Dilantin does have some side effects, and discussing this with your neurologist in terms of re-evaluation of medication levels WB wise.

Not at all: Your Dilantin level is below the thraputic level if you are seizure free for 15 years with dilantic level of 3.2.You should discuss with your neurologist or family doc if you should be taking it or can try tapering of.
