Hi Jean
Welcome to HealthcareMagic.
She will have to take the drug till she is prescribed to.Generally , anti epileptic drugs are prescribed for longer period like years.If she has any
cold or
fever , it is always better to consult a Doctor before giving her any medicine.The choice of drugs need to be specific when to be given along with
Valproate.
Feel free to mail me or post a comment here for more information.
Take care.
