hi
my son aged 11 years has been on sodium valproate (valparin syrup) 6 ml twice a day for the past 8 years. he has had the same dosage for all these years and no seizures. once a year my neurologist makes him have a sleep deprived eeg that has been coming abnormal so he has asked us to continue the medication. this year he ahs suddeny asked us to chnage to keppra. i am confused now because this is rather sudden and my son is used to the valparin now and has no side effects as such. the doctor says that this is for better seizure control since eeg is abnormal but the eeg has been abnormal for the past 8 years then why now? i am all confused and when i told the doctor i will change medication only during vacation time so that i can moniter him. he said ok to that but since blood levels of valproic acid are 32 %(they have been 40% for past 8 years) i should increase the dose. all the literature i have read says that dosage is symptom related and not blood level related . any adv is v useful since i am very worried about making any change now. thanks all!
