I don't take keppra (levetiracetam) at nite but my dr wants me to take 500 in am and 250 in pm will that mess with my seizures when they have been gone since december?

Ask MD: If your MD has advised a change, there must be a reason. Did you have a recent blood test looking at the level of the medication in your blood stream? When you are unsure of why your MD has asked you to change, contact them and ask for clarification. Keppra (levetiracetam) is often dosed twice a day. http://www.drugs.com/pro/keppra.html
