Medication administration via intravenous push presents multiple potential advantages; however, there may be an increased risk of adverse drug reactions. In 2020, Brigham and Women’s Hospital changed levetiracetam intravenous administration to intravenous push (IVP). The purpose of this analysis was to compare the safety profile of IVP to intravenous piggyback (IVPB) levetiracetam administration. This institutional review board-approved, single-center, pre-post analysis was performed between 1 November, 2019 and 30 May, 2020. The electronic health record was used to identify all administrations of intravenous levetiracetam greater than 1000 mg in patients ≥ 18 years old. The major safety outcomes included hypotension, bradycardia, drug-induced sedation, and intravenous site reactions such as phlebitis and infiltration. The major efficiency outcome was the time from pharmacy order verification to first-dose administration. A total of 498 administrations in 162 patients were included in the analysis: 252 administrations in 84 patients in the IVP group and 246 administrations in 78 patients in the IVPB group. The incidence of bradycardia was 7 vs 3 (3.2% vs 1.5%, p = 0.34); hypotension 10 vs 6 (5.2% vs 3.5%, p = 0.44); sedation 21 vs 36 (19.3% vs 27.9%, p = 0.12); and peripheral IV site reactions 0 vs 1 (0% vs 0.6%, p = 0.39) in the IVP vs IVPB groups, respectively. The median time between order verification and first-dose administration was significantly reduced in the IVP vs IVPB group (23.5 vs 55 min, p < 0.001). Intravenous push levetiracetam administration of doses up to 4000 mg was associated with a similar incidence of cardiovascular, sedation, and infusion site-related adverse events compared to IVPB and resulted in a significant reduction in time to first-dose administration. Intravenous push levetiracetam in doses as high as 4000 mg may be considered safe with appropriate monitoring.
