Based on the frequency of jerking you've described, I think she would need to reviewed by Pediatric Neurologist
again. Possibilities are either Convulsions or myoclonic jerks. May be see another Neurologist in your city.
Medicines like Valparin are used for long term control in Epilepsy
. I have not seen if being used only during fever
Important thing to know would be how has her development been so far?
Any medicine has got side effects. Important thing to keep in mind is whether the benefit of taking medicines outweigh the risks associated with it.
Please do get in touch with Pediatrician/Neurologist and get her checked over. She may need further investigations.
