The Use of Neuraminidase Inhibitors in Teenagers May Not Increase the Risk of Neuropsychiatric Adverse Events: A Nationwide Population-based Retrospective Study

Background Pandemic influenza virus is a public health issue, and the neuraminidase inhibitors (NIs) “Oseltamivir” and “Zanamivir” are effective treatments. While teenagers use NIs, there are concerns regarding neuropsychiatric adverse events (NPAEs). Aim We aimed to use the Taiwan National Health Insurance Research Database to identify the correlation between NPAEs and NIs use in teenagers aged 13–19 years. Methods The final population between 2000 and 2015 included in this study was 3698 individuals, with 2287 individuals having received “Oseltamivir” and “Zanamivir” (study cohort group) and 9148 individuals not receiving “Oseltamivir” and “Zanamivir” (comparison cohort group). We initially used a multivariate Cox regression analysis during the tracking period to determine the cumulative incidence of NPAEs. Results Our findings revealed no significant increase in the likelihood of developing NPAEs in the study group. The Kaplan–Meier survival curve demonstrated that individuals who received “Oseltamivir” and “Zanamivir” were not associated with statistically significantly increased NPAEs compared with controls (log-rank test, P = 0.724). Conclusion No more risk in comparison of the normal population in our study, and the safety of “Oseltamivir” and “Zanamivir” is established treatments for influenza.
