BACKGROUND:

Acetaminophen is extensively used during pregnancy. But there is a lack of population-representative cohort studies evaluating its effects on a range of neuropsychological and behavioural endpoints. We aimed to assess whether prenatal exposure to acetaminophen is adversely associated with neurodevelopmental outcomes at 1 and 5 years of age.

METHODS:

This Spanish birth cohort study included 2644 mother-child pairs recruited during pregnancy. The proportion of liveborn participants evaluated at 1 and 5 years was 88.8% and 79.9%, respectively. Use of acetaminophen was evaluated prospectively in two structured interviews. Ever/never use and frequency of use (never, sporadic, persistent) were measured. Main neurodevelopment outcomes were assessed using Childhood Autism Spectrum Test (CAST), Conner's Kiddie Continuous Performance Test (K-CPT) and ADHD-DSM-IV form list. Regression models were adjusted for social determinants and co-morbidities.

RESULTS:

Over 40% of mothers reported using acetaminophen. Ever-exposed offspring had higher risks of presenting more hyperactivity/impulsivity symptoms Comment is also behind publisher paywall,%20K-CPT%20commission%20errors%20(IRR%20=%201.10,%201.03-1.17),%20and%20lower%20detectability%20scores%20(coefficient%20β = -0.75,%20-0.13--0.02).%20CAST%20scores%20were%20increased%20in%20ever-exposed%20males%20(β = 0.63,%200.09-1.18).%20 Increased%20effect%20sizes%20of%20risks%20by%20frequency%20of%20use%20were%20observed%20for%20hyperactivity/impulsivity%20symptoms%20(IRR%20=%202.01,%200.95-4.24)%20in%20all%20children,%20K-CPT%20commission%20errors%20(IRR%20=%201.32,%201.05-1.66)%20and%20detectability%20(β = -0.18,%20-0.36-0.00)%20in%20females,%20and%20CAST%20scores%20in%20males%20(β = 1.91,%200.44-3.38).

Lawsuits and class-action lawsuits continue thru 2017

  • No apparent change by the FDA other than to reduce the maximum strength pill and put a black box warning on Tylenol, but apparently not on the 600 other medicines containing acetaminophen
    •    ~ Note: It is extremely easy for a person to take more than one pill
