I just used the drug interaction checker at Medscape.
I typed in Depakote, Neurontin, Ibuprofin, Naproxen, Isoniazid (INH) and it said "no interactions found".
Here is the link to the interaction checker

You have to sign up as a member of Medscape to use it, but the sign-up is free and I have never gotten any spam from them for signing up and becoming a member.
Hope that helps,
