There is no specific antidote for overdose with Levetiracetam. If indicated, elimination of unabsorbed drug should be attempted by emesis or gastric lavage; usual precautions should be observed to maintain airway. General supportive care of the patient is indicated including monitoring of vital signs and observation of the patient's clinical status.

The major metabolic pathway of levetiracetam (24% of dose) is an enzymatic hydrolysis of the acetamide group. No CYP450 metabolism detected. Route of Elimination: Sixty-six percent (66%) of the dose is renally excreted unchanged. The metabolites have no known pharmacological activity and are renally excreted. The mechanism of excretion is glomerular filtration with subsequent partial tubular reabsorption. Half Life: 6-8 hours
