seizures
"I suffered a traumatic brain injury from being assaulted. Was on Dilantin for a few months. Due to no seizures they withdrew the Dilantin but a couple of months later I suffered my first grand mal seizure. I was put on Epilim (Sodium Valproate) but continued to have grand mal's. I had 3 in a week while at the highest level of Epilim and woke in hospital to find out they gave me Dilantin through a drip. They gradually reduced the Epilim whilst introducing Keppra. I was toxic for about 6 weeks but believe it was because the Dilantin level had increased. I have been seizure free for about 6 months now whilst the Dilantin is below the therapeutic range so I hope it's the Keppra. My neurologist wants to have me on Keppra only."
