WHO’s Most Recent Statement

The World Health Organization recently reviewed the research on acetaminophen (paracetamol) use in pregnancy and autism. Their conclusion? The evidence is inconsistent and does not prove a causal link. In other words, science does not support the claim that taking acetaminophen during pregnancy causes autism.

The Problem With Blame

Despite this, we have heard the headlines that suggest otherwise. Unfortunately, these narratives put unfair blame on mothers, echoing outdated and harmful ideas that parents are responsible for their child’s neurodevelopmental differences. This can create unnecessary guilt and shame, at a time when families need compassion and support.

The Risks of Misinformation

Misinformation doesn’t just cause guilt—it can also change behavior in harmful ways. For example, some pregnant people may avoid acetaminophen altogether, even though it’s one of the safest options for fever and pain relief during pregnancy. Untreated high fevers, on the other hand, may pose far greater risks for both mother and baby.

What We Know About Autism

Autism is a complex neurodevelopmental condition influenced by many factors, including genetics and some environmental influences. It is not caused by a single decision, action, or medication during pregnancy. Oversimplifying the causes of autism undermines science and unfairly stigmatizes parents.

Moving Forward: Evidence Over Fear

Health decisions should be based on strong evidence, not speculation, headlines, or fear. The WHO’s statement reminds us that while continued research is important, we must not jump to conclusions that fuel anxiety or place blame where it does not belong.

Bottom Line

Acetaminophen, when used as directed, remains a safe and commonly recommended medication in pregnancy. Let’s move the conversation away from blame and misinformation, and toward compassion, science, and support for families.

👉 If you’re a parent who has felt guilt or anxiety after reading claims about autism and acetaminophen, know this: you are not to blame. Evidence matters, and the evidence does not support these claims. Let’s continue to uplift one another with facts, not fear.
