Have you had any recent imaging done of your head, i.e. CT or MRI?
Are your dilantin levels therapeutic? (this is a lab).
Hi there. Since your frequency of seizures has increased you need to have a fresh evaluation of your neurological function clinically, with a recent MRI brain and an EEG. The antiepileptic drugs need to be checked for a dosage modulation, assessment of adverse effects due to chronic usage over years like megaloblastic anemia, gingival hypertrophu and osteomalacia with phenytoin.
Take care.
