WHO Responds to the Debate over Paracetamol
(Acetaminophen) and Its Link to Autism
In recent days the public debate has intensified following claims that taking paracetamol (commonly known as acetaminophen or Tylenol) during pregnancy increases the likelihood of children developing autism spectrum disorder.
This controversy has caused widespread anxiety among pregnant women and parents. So what does the scientific evidence and major health organizations say?
First
from a scientific-methodology perspective:
most studies examining
the relationship between paracetamol and autism are observational.
Some of these studies found a small statistical association
but association
- is not proof of causation. Stronger designs, such as sibling-controlled studies
- have reduced the strength of this association
- and in some cases sibling analyses
did not show
- a clear increase in autism risk linked to maternal paracetamol use.
- This suggests that shared familial and environmental factors
- may explain part of the initial observations.
Second
the official positions of major health bodies are measured and cautious:
the World Health Organization
has stated that
there is no conclusive evidence linking acetaminophen use during pregnancy to autism spectrum disorder and urged reliance on scientific evidence rather than premature alarm. At the same time, the U.S.
Food and Drug Administration
has announced it is reviewing product labeling in light of accumulating studies that suggest potential associations, while emphasizing that current evidence does not prove a causal relationship.
These statements indicate that the data
are still mixed and regulatory assessments are ongoing.
Third
specialist medical associations advise moderation: the American College of Obstetricians and Gynecologists (ACOG) and maternal–fetal medicine groups have affirmed that acetaminophen remains an accepted option for treating pain and reducing fever during pregnancy when needed.
They recommend using
the lowest effective dose for the shortest possible time and consulting a physician for frequent or prolonged use. They also note that untreated or prolonged fever may be harmful to the fetus, so treating fever when necessary remains important.
Fourth
why do study results differ?
- Variations stem from study design differences methods of
- recording drug use (self-reported data are prone to recall bias)
- differing confounding variables
(such as infections or the fever itself, socioeconomic factors)
and the fact that autism is influenced by multiple genetic and environmental factors—making it extremely difficult to single out one factor as a direct cause.
In conclusion:
the practical message from scientific reviews and health authorities is that there is no need for panic, but there is reason for caution and prudent action.
General advice:
if you are pregnant or planning pregnancy, consult your physician before using any medication regularly; use paracetamol only when necessary, at the minimum effective dose and for the shortest duration, and avoid unnecessary chronic use.
Follow your doctor’s guidance in treating fever or pain, because in some cases the risks of untreated fever may outweigh the risks of the medication.
