Researchers debunk long-standing concern about flu treatment in children

For many years, medical professionals debated whether or not a standard antiviral remedy used to deal with flu in youngsters brought on neuropsychiatric occasions or if the an infection itself was the offender.

Now researchers at Monroe Carell Jr. Youngsters’s Hospital at Vanderbilt have debunked a long-standing concept about oseltamivir, often known as Tamiflu.

In response to the examine, revealed in JAMA Neurology, oseltamivir therapy throughout flu episodes was related to a diminished danger of significant neuropsychiatric occasions, reminiscent of seizures, altered psychological standing and hallucination.

“Our findings demonstrated what many pediatricians have lengthy suspected, that the flu, not the flu treatment, is related to neuropsychiatric occasions,” mentioned principal investigator James Antoon, MD, Ph.D., MPH, assistant professor of Pediatrics within the Division of Pediatric Hospital Drugs at Monroe Carell.

“The truth is, oseltamivir therapy appears to stop neuropsychiatric occasions moderately than trigger them.”

Key factors:

• Influenza itself was related to a rise in neuropsychiatric occasions in comparison with youngsters with no influenza, no matter oseltamivir use.
• Amongst youngsters with influenza, these handled with oseltamivir had about 50% discount in neuropsychiatric occasions.
• Amongst youngsters with out influenza, those that had been handled with oseltamivir prophylactically had the identical fee of occasions because the baseline group with no influenza.

“Taken collectively, these three findings don’t help the idea that oseltamivir will increase the danger of neuropsychiatric occasions,” mentioned Antoon. “It is the influenza.”

The crew reviewed the de-identified knowledge from a cohort of youngsters and adolescents ages 5–17 who had been enrolled in Tennessee Medicaid between July 1, 2016, and June 30, 2020.

In the course of the four-year interval, 692,295 youngsters, with a median age of 11 years, had been included within the examine cohort. Throughout follow-up, examine youngsters skilled 1,230 severe neuropsychiatric occasions (898 neurologic and 332 psychiatric).

The scientific outcomes definition included each neurologic (seizures, encephalitis, altered psychological standing, ataxia/movement disorders, imaginative and prescient modifications, dizziness, headache, sleeping problems) and psychiatric (suicidal or self-harm behaviors, temper problems, psychosis/hallucination) occasions.

“The 2024–2025 influenza season highlighted the severity of influenza-associated neurologic problems, with many facilities reporting elevated frequency and severity of neurologic occasions throughout the latest season,” mentioned Antoon.

“It’s important for sufferers and households to know the true risk-benefit profile of flu therapies, reminiscent of oseltamivir, which might be beneficial by the American Academy of Pediatrics.”

“These flu therapies are protected and efficient, particularly when used early in the midst of scientific illness,” added senior writer Carlos Grijalva, MD, MPH, professor of Well being Coverage and Biomedical Informatics at Vanderbilt College Medical Heart.

Investigators hope the findings will present reassurance to each caregivers and medical professionals in regards to the security of oseltamivir and its function in stopping flu-associated problems.
