Brivaracetam (Briviact®) interferes with measurements of levetiracetam (Keppra®) in the ARK Levetiracetam Assay. Patients undergoing a switch in drug therapy involving Keppra and Briviact should not be monitored for levetiracetam using the ARK assay. Serum levels of levetiracetam and/or brivaracetam should be confirmed by a valid chromatographic method if there is a possibility these drugs are co-present in circulation.
