Hello,
You are not under good control for your seizures so I would agree that a change in management would likely be in your best interest.
If you are not being followed by at least a
NEUROLOGIST (better yet, EPILEPTOLOGIST) then, I would make the request of your PMD.
Phenytoin at 100mg. is clearly not therapeutic for you since you continue to have breakthrough seizures.
If you've not had blood levels checked recently then, that would be the 1st step.
The second step, if you ARE therapeutic then, consideration to raising your dose to at least 3X daily should be given as this is a more conventional dose for someone with active seizures.
Your continuous seizures may also be contributing to your
headaches so by bringing the convulsions under better control you may automatically reduce headaches.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Dariush Saghafi, Neurologist
