I have found that with myself,
Topamax works well with controlling the seizures,
and has much less effect on
liver functions, making it a much safer drug for me. I would be intersted to know what 3 meds he is on for seizures, any severity of liver damage so far by hep c, and how old he is. As always, consulting with his neurologist and his GI in conjunction is the safest bet. As far as websites for the two, I have not found any.
