Your child had seizures even in absence of fever
this indicates that what she was suffering from was Fever precipitated seizure not Febrile seizure. The seizure was controlled on carbamazepine
and some other antiepileptics which you have not mentioned.
When we prescribe a combination of antiepileptics for long term, serum level of drugs should be checked in between as there is a variety of interaction between different drugs.
are good drugs to control seizure. You have not mentioned whether the drugs which you were giving earlier stopped suddenly or tapered or continued as it is an important part of management.
I would suggest you to continue the valproate and rivotril and get a serum level done for antiepileptics as this will help in reducing the number of drugs without new episodes of seizures.
