levetiracetam is the generic of Keppra. It actually has less side effects than Keppra. I take Levetiracetam with another supplement antiseizure and I have had less seizures in 2022 and this year.
I agree, Keppra is a horrible drug. It also messed with me mentally to the point I thought I was losing my mind.
Keppra - or Levetiractam - was awful for me! I was taken off it in the end. I was tired all the time, I felt nauseous, it was just horrendous! If you are not happy ask your nurse/doctor about a newer or better anticonvulsant. Just look after you and your health. The person who put you on the drug isn’t the person who has to put up with the side effects - remember that!
