By the way, I think you mean Briviact.
It is a newly approved drug and the ONLY FDA indication [approval] is for adjunctive therapy for partial onset seizures when a fist medication is not working well enough.
So: it is not indicated for the other purposes you mention.
It is only indicated for partial onset seizures and this might not be your seizure type.
It is not indicated as a primary , first line drug.
In other words, any other use is either not indicated or in the research stages only.
This might be an explanation for your doctor's decision.
