Hi findacure, welcome to CWE!
I'm sorry you're having to cope with this. i know it can feel very sary, especially early in the diagnosis when it feels like everything is a mystery.
It is tough to predict any individual's seizure outcomes -- everyone is different. Sometimes it can take a while to find the right medicine, or the right dose. Unfortunately a part of having a seizure disorder (or being the caretaker of someone with a seizure disorder), is being patient until the right balance is struck between seizure meds, seizure dosages, seizure control, and side effects. Keppra is often used because it can be ramped up pretty quickly. It shouldn't take more than a week to see if your daughter is responding to it, but it may take some tinkering with the dosage. Once she finds a working dose, it's very important to take that dose consistently. In general, Keppra works well, though it can sometimes have the side effect of making someone moody or cranky. If for some reason it doesn't work for your daughter there are quite a few other meds to try.
I would check with your daughter's doctor about what precautions to take before sending her back to school, as well as what information to provide to her school nurse, classmates, and teachers.
Let us know how she does on the keppra -- I hope the latest dose works.
Best,
Nakamova
