125 isn't really considered a very high dose for epilepsy. But I'd be most interested in how quickly the taper is--if she has side effects as she goes up in doses, keep in mind it is up to you as the patient's parent to participate in decisions, and you can suggest that you slow down the increase schedule, both to minimize side effects and to see how she is doing in gaining control. Doctors have a tendency to increase too quickly, as well as take patients off meds too quickly. Most of us on here have learned from personal experience that sometimes we need to go more slowly than our doctors recommend, and being our own advocates and partnering in decisions makes our experiences with these drugs better. Just something to keep in mind as you go through this process.
Yep, I want to say 6 weeks but I'm honestly not sure. My wife knows. As I mentioned in my first post, she's a pediatrician so she's really wanting to be careful and conservative about this.
