seizures
"I've had seizures on and off for about 12 years and have tried Dilantin, Depakote and Tegretol. When my generalized seizures started up again this past year, I started back on Depakote, but that didn't do it. My doctor suggested Keppra and mentioned that it was filtered through the kidneys rather than the liver like the others so I tried it. I've increased the dose from 1000mg/day to 2000mg/day and so far it hasn't completely controlled my generalized seizures. Overall, this drug only seems to interfere with my concentration a little and I'm just slightly drowsy. "
