I don't know anythign about Keppra. I take Lamictal and phenobarbital. Before I got pregnant I was on 400mg of lamictal a day, and 100mg of phenobarbital. Now, at 29 weeks pregnant I am up to 1000mg of lamictal, still on 100mg of phenobarbital. Before I got pregnant, I hadn't a had a problem on those meds for almost five years. But then as I got farther along I have had a few problems, that is common though. Only one actual seizure, but three "episodes" where I sort of lost a little bit of time, if that makes sense. But didnt' actually quit breathing or anything.
