Associations of oseltamivir with neuropsychiatric and behavioral adverse events: A systematic review and meta-analysis.
Synthesis in Journal of managed care & specialty pharmacy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundInfluenza causes approximately 3-5 million severe cases and 290,000-650,000 deaths annually, and oseltamivir is considered the first-line pharmacotherapy. Recent reports on neuropsychiatric events (NPEs) associated with the use of oseltamivir necessitated a systematic safety profile review.
objectiveTo systematically review and meta-synthesize the evidence on the associations of oseltamivir with adverse NPEs and behavioral events.
methodsWe conducted a systematic review and meta-analysis following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using the PubMed/Medline, Embase, and Cochrane Library databases from inception through October 31, 2024. Studies comparing oseltamivir with other control groups for NPEs were analyzed. Outcomes were categorized into (1) affective disorders, (2) neuropsychiatric symptoms, (3) anxiety disorders, (4) schizophrenic/psychotic disorders, and (5) suicide-related behaviors.
results9 studies with 1,139-3,352,015 patients were identified. Oseltamivir significantly associated with a lower overall NPE incidence (risk ratio [RR] = 0.83; 95% CI = 0.72-0.97), except in patients younger than 20 years. Subgroup analyses showed significant association with a lower incidence risk in suicide attempts across all ages (RR = 0.60; 95% CI = 0.46-0.77) and in schizophrenia/psychotic disorders for patients younger than 20 years (RR = 0.75; 95% CI = 0.61-0.93).
conclusionsThis is the first comprehensive meta-analysis examining the associations of oseltamivir with various NPEs and behavioral adverse events, and we found no evidence supporting increased risks of these adverse events with oseltamivir use.
