US President Donald Trump has recently claimed that using acetamophine (also often known as paracetamol and often known as Talnol) within the United States is promoting a rise in autism diagnosis while pregnant. Then they proceed to suggest pregnant women that in the event that they experience fever or pain, they must be “hard” as an alternative of using normal pain.
This announcement has created alarm and confusion around the globe. But despite Trump's claim, there isn't a strong scientific evidence to back it. Our study of about 25 million births in Sweden appeared in 2024 Shows no evidence The use of acetaminophine while pregnant increases the chance of autism. To date, that is the most important study on this topic.
To understand whether acetaminophen is de facto in danger in pregnancy, we turn to Sweden's national health entries, that are probably the most comprehensive on this planet. After our study, they were traced after about 2.5 million children born between 1995 and 2019.
Using prescription records and interviews that the midwives made during pre -birth tours, we are able to see which moms have reported to make use of acetaminophen (about 7.5 % of pregnancy) and which isn't.
We also ensured that any variables which have affected the outcomes of our statistics evaluation – including controlling health aspects, resembling fever or pain, which affects whether a mother uses acetaminophine during her pregnancy. It was to make sure a more fair comparison between the 2 groups.
After that we saw the youngsters's neurodeficiency results – especially whether or not they were diagnosed autism, ADHD or mental disability.
The real strength of our study has come from having the ability to compare siblings. This allowed us to check the youngsters born to the identical mother, where one child was used during an baby's pregnancy but not one other. We compared greater than 45,000 siblings, where a minimum of one sister was diagnosed with autism.
This sibling design is powerful since the siblings share most of their genetics and family environment. This allows us to tease whether the drug itself is liable for any clear risks to the results of neurodeficiency – somewhat than family traits or basic health conditions.
Acetaminophen Use
When we first saw the complete population, we saw a pattern that echoes the echoes Preliminary studies: Children whose moms reported using acetaminophine while pregnant were more more likely to diagnose autism, ADHD or mental disability.
But once we compare siblings, the association disappeared completely. In other words, once we compared the sets of siblings where someone was exposed to Estaminophen within the uterus and was not one, there was no difference in the opportunity of diagnosing autism, ADHD or mental disability.

Our study isn't just going to check this query. Researchers in Japan recently Published a study Similar siblings using the competition design, and their results are closely matching us.
The vital thing is, they created our ends in a population with a special genetic background and where the samples of using acetaminophen while pregnant are quite different. About 40 % of moms in Japan reported drug use while pregnant. In comparison, lower than 10 % of Swedish moms used it.
Despite these differences, the result was the identical. When comparing siblings, there isn't a evidence that using acetaminophen while pregnant increases the chance of autism or ADHD.
A major change from these results has been identified Preliminary studiesWhich relied on more limited data, used small groups and didn't calculate genetic differences. They also didn't fully calculate why some moms used pain while pregnant while others didn't.
For example, the moms who're more likely to take acetaminophen are also more more likely to have migraine, chronic pain, fever or serious infection. These are the conditions which are themselves Genetically connected to Autism or ADHDAs well as a Child probability Later, one in every of these conditions must be diagnosed.
This kind of “confused factors” associations can create an association that seems convinced on the surface, but may not reflect the actual relationships of the cause and effect.
This raises the actual query on the minds of many individuals: what does it mean should you are pregnant and coping with pain or fever?
It is vital to know that non -treated disease will be dangerous while pregnant. A high fever in pregnancy, for instance, is thought to extend The risk of complications For each mothers and kids. As the president advised, “tighten it,” isn't a danger -free option.
This is the explanation why skilled medical organizations resembling American College of Ogestions and Gynecologists and UK medicine and health care products are underway. Recommend acetaminophine (Paracetamol) as a The safest fever reducing and savior of pain During pregnancy when the bottom effective dose is used and only when needed. It has been guiding for a long time.
However, if anyone feels the necessity to take acetaminophen repeatedly in the long term, that is the very best decision by consulting their doctor or midwife. But the concept that using acetaminophine while pregnant causes autism doesn't help the very best available science.
The biggest risk is that the alarm messaging will discourage pregnant women from treating pain or fever – endanger each themselves and their children.
