seizures
"I was placed on Keppra in January 2009 by an emergency room physician after a reported seizure, which had no professional diagnosis. A neurologist whom I saw post emergency kept me on the medication as I reported no side effects. I had what I now believe to be a fainting spell related to an atrial fibrillation condition of my heart and a strenuous run, without a "cool-down". I am pushing to get off this drug, as I experience dizziness, light-headedness, sleepiness and somnolence, fatigue and exhaustion most of the time. I am a 2008 Herat Valve transplant recipient and on diuretics and blood thinners, both required to avoid congestive heart failure and embolisms(artificial valve)."
