Lancet Study Confirms Paracetamol Safe in Pregnancy, No Autism or ADHD Risk
Paracetamol Safe in Pregnancy, No Autism Risk: Lancet

Lancet Study Gives Green Light to Paracetamol Use During Pregnancy

A comprehensive new study published in The Lancet has delivered reassuring news for expectant mothers. Researchers confirm that taking paracetamol during pregnancy does not increase the risk of autism, attention-deficit hyperactivity disorder (ADHD), or intellectual disability in children. This finding directly addresses widespread confusion and anxiety that emerged following controversial statements in recent years.

Putting Earlier Concerns to Rest

Earlier studies had suggested possible small associations between prenatal paracetamol exposure and neurodevelopmental issues. However, the new analysis reveals those studies suffered from significant methodological flaws. They often failed to account for crucial genetic factors and underlying maternal health conditions that could skew results.

"Our findings suggest that previously reported links are likely to be explained by genetic predisposition or other maternal factors such as fever or underlying pain, rather than a direct effect of the paracetamol itself," explained Professor Asma Khalil, a lead researcher from City St George's, University of London.

The Gold-Standard Sibling Comparison Approach

This research represents the most rigorous analysis conducted to date, examining data from 43 separate studies. The team employed a sophisticated sibling-comparison design that compared pregnancies where mothers took paracetamol to those where they did not.

Critically, researchers analyzed siblings born to the same mother, where one pregnancy involved paracetamol exposure and another did not. This powerful approach helps control for shared genetics, family environment, and long-term parental characteristics that traditional studies cannot fully account for.

The massive dataset included:

  • 262,852 children assessed for autism
  • 335,255 children assessed for ADHD
  • 406,681 children assessed for intellectual disability

When comparing pregnancies with no paracetamol exposure to those with exposure, researchers found no increased risk for any of these neurodevelopmental conditions.

Why This Matters for Maternal Healthcare

Paracetamol, also known as acetaminophen, remains the most commonly used pain reliever and fever reducer during pregnancy worldwide. Medical organizations globally recommend it as a first-line option because its safety profile is generally more favorable than alternatives like non-steroidal anti-inflammatory drugs or opioids.

Professor Khalil emphasized the practical implications: "The message is clear – paracetamol remains a safe option during pregnancy when taken as guided. This is important as paracetamol is the first-line medication we recommend for pregnant women in pain or with a fever."

Researchers warn that avoiding paracetamol when medically needed could unintentionally increase harm. Leaving significant pain or fever untreated poses known risks to both mother and developing baby.

Medical Community Welcomes Clarity

Dr. Sanjay Gupte, former president of the Federation of Obstetrics and Gynaecologists' Society of India, welcomed the study's conclusions. "When the paracetamol controversy blew up in social media, some pregnant patients of mine who had taken paracetamol became extremely worried. I repeat, taken in the proper dose, there is no cause for concern," he stated.

The research team used the Quality In Prognosis Studies (QUIPS) tool to evaluate potential bias in all included studies. Their gold-standard review aligns with recommendations from major medical organizations worldwide and should help end unnecessary skepticism about paracetamol use during pregnancy.

Expectant mothers can now feel reassured that they have a safe, effective option for managing pain and fever when following medical guidance. This clarity comes at a crucial time when evidence-based information is essential for informed healthcare decisions during pregnancy.
