Subcutaneous Levetiracetam Administration in Latino Patients on Home Care

Abstract

Background: Levetiracetam has a favorable pharmacology profile to be used subcutaneously. However, its subcutaneous use is still considered off-label as this is beyond its license. The evidence base for its safety, tolerability, and efficacy is limited to observational studies. Objectives: To report the safety and efficacy of subcutaneous levetiracetam in Latino patients on home care. Design: Observational retrospective case series study. Subjects: Consecutive sample of Latino adults with life-limiting illnesses. Methods: A case series framework with 4 domains (selection, ascertainment, causality, and reporting) to ensure reporting quality was used. Additionally, 8 relevant outcomes established in a previous comprehensive review, were collected and reported. Adverse reactions were documented using the Common Terminology Criteria for Adverse Events. Results: Fifteen Latino patients with oncological and non-oncological diagnoses received subcutaneous levetiracetam for a mean of 21 days on home care. Levetiracetam was most frequently initiated subcutaneously due to loss of the oral route. The average dosage of subcutaneous levetiracetam was 1200 mg. Only 1 patient required a dose adjustment, and only 2 patients experienced a total of 5 seizures during the therapy trial. No adverse reactions were reported. Conclusions: Subcutaneous levetiracetam appears to be effective and safe. This case series of Latino patients in home care expands the evidence of its use in the home care setting. The preliminary data reported by now on multiple case series warrants robust trials.
