Anti-seizure prophylaxis is routinely utilized during busulfan administration for HSCT. We evaluated the feasibility and efficacy of levetiracetam in children undergoing HSCT. A total of 28 children and young adults received levetiracetam during HSCT and the outcomes and costs were compared to a historical, but similar cohort of 25 patients who had received fosphenytoin. Levetiracetam was well tolerated and was efficacious in preventing seizures. Cost of drug, administration, and monitoring were also similar among the two groups. Due to non-induction of the hepatic cytochrome P450 enzymes, levetiracetam may lead to better dose assurance of busulfan in targeted dose regimens for HSCT.
