Abstract

Background

Although the potential risk of neuropsychiatric adverse events (NPAEs) upon administration of oseltamivir has been raised in case reports, the association between the use of oseltamivir and the risk of NPAEs is unclear.

Objectives

We aimed to evaluate whether the use of oseltamivir triggers NPAEs.

Patients and methods

We conducted a population-based case-crossover study using the National Sample Cohort data from the National Health Insurance Service in South Korea. From a total of 236 348 incident patients with NPAEs as either a primary or secondary diagnosis, our final case series included 5322 patients with a prior prescription for oseltamivir between 2009 and 2013. Exposure to oseltamivir was assessed during 2, 7, 14, 28 and 56 day hazard periods prior to each patient’s NPAE. Three pre-consecutive control periods were matched using the same time windows. Conditional logistic regression analysis was used to estimate adjusted ORs (aORs), adjusting for time-variant diagnosis of influenza and concomitant medications.

Results

Matched analyses found a consistently increased risk of NPAEs associated with the use of oseltamivir in the 2 day (aOR 1.90, 95% CI 1.29–2.81), 7 day (aOR 1.32, 95% CI 1.00–1.74), 14 day (aOR 1.28, 95% CI 1.03–1.60), 28 day (aOR 1.25, 95% CI 1.06–1.47) and 56 day (aOR 1.13, 95% CI 0.99–1.29) hazard periods compared with use in the three control periods.

Conclusions

This study found that the short-term use of oseltamivir triggers the incidence of NPAEs. Early monitoring of NPAEs may be required when prescribing oseltamivir with careful consideration of the risk–benefit balance of oseltamivir.

I am an Italian blogger, active since 2005 with main focus on emerging infectious diseases such as avian influenza, SARS, antibiotics resistance, and many other global Health issues. Other fields of interest are: climate change, global warming, geological and biological sciences. My activity consists mainly in collection and analysis of news, public services updates, confronting sources and making decision about what are the 'signals' of an impending crisis (an outbreak, for example). When a signal is detected, I follow traces during the entire course of an event. I started in 2005 my blog ''A TIME'S MEMORY'', now with more than 40,000 posts and 3 millions of web interactions. Subsequently I added an Italian Language blog, then discontinued because of very low traffic and interest. I contributed for seven years to a public forum (FluTrackers.com) in the midst of the Ebola epidemic in West Africa in 2014, I left the site to continue alone my data tracking job.
