It takes approximately 5.5 x elimination half lifes for a medicine to be out of your system.
Keppra (Levetiracetam) has a plasma half-life in adults of 7 ± 1 hour and is unaffected by either dose or repeated administration.
Therefore it can take about 44 hours (5.5 x 8 hours) for Keppra to be out of ones system.
