My husband recently had two brain surgeries. He was put on keppra to prevent seizures. He accidently took two 500mg tablets within a 3 hour space of time. He has been sleeping since. He has awakened to use the bathroom, but is very unsteady on his feet. His blood sugars are very high. I was wondering how long does keppra stay in your system. It has been around 34 hours since he had taken the last dose. In fact, he hasn't even taken any medication since that time.
