It can take about 44 hours for Keppra to be out of ones system.
The elimination half-life of a medication is the time it takes for blood levels of the medication to be reduced by half. It takes approximately 5.5 x elimination half-life for a medicine to be out of your system.
Keppra 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 eliminated.

Metabolism, age, health, weight and the amount and frequency of the drug taken, are all factors that can affect the rate at which the body can clear the drug from your system.

Keppra (levetiracetam) belongs to the class of medications called antiepileptics. It is used in combination with other seizure-control medications to treat and prevent seizures associated with epilepsy.
