I was never given those numbers you list above during the 18 months I
used it (1993).  I'm not sure what they'd mean to me vs. my Neuro, but
others don't have as good a Neuro as I had.
   Mine told me that Dilantin is one of the oldest, so best studied Med.
and is often given first to those who might be able to use it, as potential
side effects etc. are documented  (I had heard it was used in ~1930s? ),
since it's also cheaper.
   For my type of Complex Partials, I had to phase it out and replace it
with a stronger med (Tegretol) to get control that was more reliable that
what I was getting with just the Dilantin.   (I had erratic seizures,  from
1 a week to one each 4 weeks, back to 1 a week,  with nothing that I could
relate to when a szr. would arise or not. )
   There are some others here who use or have used Dilatin too, but a
couple don't read the group  each day, so keep checking here for more recent
experiences.
   (Did you check http://efa.org  or with your *Pharmacy to see if there
are any things listed to avoid?  Tegretol for example gets messed up with
Grapefruit juice, and it took me a while to relate the few times a month I
used G.fruit to the szr. or auras I had 24-36 hours after.)     G.

FYI -

I looked up the lab values in a reference book.  It says that AST can be
elevated due to recent seizure activity.  Dilantin can cause increased ALT
levels (the book lists this as an interfering factor with the test, in
other words a falsely elevated level.)

On the other hand, I looked Dilantin up in a drug book and it lists
hepatitis (which is inflammation of the liver) as a dose related adverse
reaction to the drug.  So I would definitely keep on your Dr. about this.
