It’s Tylenol?


RFK jr claimed over a month ago that this month they were going to find and announce the cause of autism. We all knew he was full of shit — he’s permanently full to the eyebrows with shit — and that this was a political game they were playing, because autism is a multifactorial syndrome with multiple enabling factors, and you’re not going to find a ‘magic bullet’ for it. Well, yesterday the gang of frauds and liars in the White House announced that there was a central link, and that it was acetaminophen, or Tylenol. This is like announcing that the cause is consuming bread — something with a widespread, long-term use that a huge number of pregnant women had eaten. Mothers with autistic children will now think that using a common, well-tested pain reliever is the cause, and blame themselves.

Trump gathered his crack team of worthless quacks to make this announcement.

Speaking from the Oval Office alongside US Health and Human Services Secretary Robert F. Kennedy Jr., US Food and Drug Administration Commissioner Dr. Marty Makary, US National Institutes of Health Director Dr. Jay Bhattacharya and US Centers for Medicare & Medicaid Services Administrator Dr. Mehmet Oz, Trump did not keep his remarks to Tylenol during pregnancy. (I don’t know who the woman is, I guess no one thinks she’s important enough to name)

Of course Trump tried to take credit for this “discovery”.

It’s too much liquid, too many different things are going into that baby, Trump said, without providing further evidence.

Extensive research has shown that there’s no link between vaccines and autism.

Trump thanked Kennedy for bringing autism to the forefront of American politics, along with me. Kennedy, a longtime anti-vaccine activist, has promoted discredited theories that vaccines cause autism.

We understood a lot more than a lot of people who studied it, Trump said.

Oh god. All the gullible people who believed him about ivermectin are now going to be telling pregnant women that they just have to suffer through headaches and fevers, all because a group of elected and appointed clowns say so. They presented no evidence for a link between autism and Tylenol, but just blithely charged in and invented one. The studies have been done to show that Tylenol is not a significant factor! Here’s one that looked at 2,480,797 children and found no connection.

Study reveals no causal link between neurodevelopmental disorders and acetaminophen exposure before birth
NIH-funded research in siblings finds previously reported connection is likely due to other underlying factors.

Acetaminophen exposure during pregnancy is not linked to the risk of developing autism, ADHD, or intellectual disability, according to a new study of data from more than 2 million children in Sweden. The collaborative research effort by Swedish and American investigators, which appears in JAMA, is the largest of its kind and was funded by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health (NIH).

Scientists compared siblings — who share genetics and other variables such as parental health, environmental exposures, and socioeconomic factors — and were able to limit the influence of other potential risk factors. This allowed them to focus specifically on, and eliminate, the risk associated with acetaminophen. The study design was unique due to the size of the population captured in the Swedish Medical Birth Register and the Swedish Prescribed Drug Register. Before siblings were considered, there appeared to be a small increase in risk for neurodevelopmental disorders in children exposed to acetaminophen, which was noted in previous studies.

Acetaminophen is commonly used as a pain reliever and fever reducer and is found in a variety of medicines available over the counter and via prescription. It is often taken during pregnancy instead of nonsteroidal anti-inflammatory drugs, known as NSAIDs, which can cause low levels of amniotic fluid, according to the Food and Drug Administration. The reasons pregnant people might take acetaminophen, including fever, or conditions such as chronic migraine, could be, and in some cases are, associated with an increased risk for later neurodevelopmental disorders following pregnancy.

One limitation of this study is that it relies on data from prescribed acetaminophen and from self-reporting from pregnant people during prenatal care. It may not capture all use or dosage in all people, particularly over-the-counter medicines. However, the number of patients included in the study sample and the ability to control for many other confounding factors support the conclusion that acetaminophen is not directly linked to an increase link of autism, ADHD, or intellectual disability.

To inform best preventative strategies, additional research is required to fully understand the genetic and non-genetic factors that increase the risk of autism, ADHD, and intellectual disability.

The effect is simply not there! Because Trump has surrounded himself with incompetent frauds, this claim is going to resonate through society and have multiple deleterious effects on American health. Makary, Bhattacharya, Oz, and RFK jr belong on a list of infamous quacks alongside disgraced “doctor” Andrew Wakefield.

    So many questions. Is it the specific brand, Tylenol, or generic acetaminophen? If they’re claiming it’s specifically Tylenol, which is a Johnson & Johnson product, how long before J&J sues the shit out of them? (They’ve got so much shit to loose.) If it’s either Tylenol or generic acetaminophen, and not vaccines, does this mean that Junior is going to lay off the anti-vax thing? That would be one good result because no one, pregnant or not, is going to miss a dose of Tylenol/acetaminophen if they need it.

    BTW, I have learned that there are limits to how much Tylenol/acetaminophen you should take. It seems like quite a lot, although sometimes not enough to deal with knee replacement pain post the opioid phase.

    But, PZ, that’s Swedish science, not MAGA science. And it was based on over 2 million Swedish babies, not American babies. Anyone with any common sense knows the two aren’t interchangeable. Equating Swedes and Americans is like equating puppies and kittens. The Tylenol connection is ironclad. Now, on to another critical MAGA position: vaccines cause weight gain. Stop vaccinating Americans, and they’ll all be as svelte as ballerinas.

    I’ve long side-eyed acetaminophen as it can be toxic. I wouldn’t take it for hangovers.

    Nearly 500 people die per year in the US, which I guess isn’t that many in the bigger picture:
    https://www.ncbi.nlm.nih.gov/books/NBK441917/

    https://www.statesman.com/story/news/politics/politifact/2022/05/03/fact-check-tylenol-killing-at-least-100-000-people-per-year/9612891002/

    The blame for autism is knuckledraggingly stupid as is anything coming from these quacks. Ron Johnson has made wild unrelated claims comparing deaths between acetaminophen and ivermectin. I just hope some stupid blueanoners don’t accidentally overdose on acetaminophen in reactance fueled spite. I never take the stuff myself, but strongly doubt it contributes to autism.

    I hope this is a teachable moment though to be careful with acetaminophen.

    Trump’s Tylenol announcement: What causes autism – and is Cuba autism free?


    Finally, Trump repeated a claim that countries without Tylenol, like Cuba, have little or no autism – framing it as evidence.

    “I mean, there’s a rumour, and I don’t know if it’s so or not, that Cuba, they don’t have Tylenol because they don’t have the money for Tylenol. And they have virtually no autism, OK. Tell me about that one.”

    As with Trump’s other claims at the event, his assertion about Cuba doesn’t stand up to scrutiny – as we’ll get to in a bit.

    And finally, is it true, as Trump claims, that autism does not exist in Cuba?

    It’s untrue – and if anything, Cuba undercuts Trump’s argument.

    Cuba officially recognises autism spectrum disorder (ASD). There are multiple specialised schools and paediatric clinics that provide diagnosis and therapy for children with autism.

    In Cuba, acetaminophen is generally known as paracetamol and is sold in government pharmacies. In other words, it is very much available and used as in other parts of the world.

    According to a 2022 study, Cuba had an autism incidence of about 2 to 4 per 10,000 children in some settings. While research on autism diagnoses in Cuba is much more limited than in the US, the data from the 2022 study shows a far lower rate of recognised cases than in the US – despite the presence of acetaminophen.

    Oh god. All the gullible people who believed him about ivermectin are now going to be telling pregnant women that they just have to suffer through headaches and fevers, …

    In theory, pregnant women could take other drugs such as aspirin or Ibuprofen.

    Except they shouldn’t.
    Aspirin, Ibuprofen, and other NSAIDS aren’t recommended during pregnancy.

    Mayo clinic: edited for length

    Is it safe to take aspirin during pregnancy?
    Low-dose aspirin (81 mg) is safe to use throughout pregnancy, and it may be recommended in some situations. Higher doses of aspirin typically are not recommended during pregnancy.

    Taking higher doses of aspirin may have risks depending on the stage of pregnancy:

    In fact, the recommended fever reducer to use during pegnancy due to safety concerns is Tylenol.

    Mayo clinic:

    If you need a pain reliever while you are pregnant, talk with your healthcare professional. Taking something other than aspirin, such as acetaminophen (Tylenol, others), may be a better choice.

    It is the same for Ibuprofen.
    The American College of Obstetricians and Gynecologists (ACOG) recommends avoiding ibuprofen during pregnancy, especially after the 20th week.

    So, the Trump regime will recommend against the preferred pregnancy pain reliever and fever reducer Tylenol, leaving these patients with no other good options.
    This is medical malpractice.

    The push-back is already happening. Per this article, Kenvue, J&J’s consumer-health business, are on the rise today after yesterday’s dip from the claim:

    Kenvue’s (KVUE.N), shares climbed 6% on Tuesday [today], rebounding from a record low hit in the previous session, as analysts pointed to the lack of new scientific evidence from the White House to support President Donald Trump linking the drugmaker’s popular pain reliever Tylenol to autism.

    “Investors were holding their breath worried that yesterday’s announcement would be a bombshell. It turned out it wasn’t, as no new scientific evidence was presented linking Tylenol to autism,” said James Harlow, vice president at Novare Capital Management.

    Strangely enough, we already know what causes autism.
    Autism spectrum disorders have a high genetic compoment and not well understood environmental factors also play a role.

    Is Autism Genetic
    April 10, 2024 By Ashley Bell

    “Autism is a constellation,” says Daniel H. Geschwind, MD, PhD, who won a National Academy of Medicine prize for investigating autism’s genetic underpinnings.

    However, an estimated 200 – 1,000 genes impact autism susceptibility. In comparison, autism cases linked to environmental exposures during early fetal development, such as prenatal exposure to valporic acid, are relatively rare.

    Autism is hereditary and therefore does run in families. A majority (around 80%) of autism cases can be linked to inherited genetic mutations. The remaining cases likely stem from non-inherited mutations.

    There’s no evidence that children can develop autism after early fetal development as a result of exposure to vaccines or postnatal toxins.

    “Everything known to cause autism occurs during early brain development,” says Dr. Geschwind.

    The heredibility of ASDs is 80% and it is polygenic, due to around 1,000 genes with small effects acting together.

    The environmental contribution isn’t as well understood as of yet.

    This might put a little nuance on my @6, but…:

    Reminds me of good times in the Dark Ages.

    In college in the 1970s, some people recommended APC tablets for hangovers and taken at the end of the evening to prevent hangovers. These were Aspirin, Phenacetin, and Caffeine tablets APC, nonprescription.
    Phenacetin is no longer available due to kidney toxicity and the current version uses Acetaminophen instead.

    The few times I tried it, it didn’t work.
    The APC tablets didn’t help and made me feel slightly sick anyway.

    The best cure for hangovers is..to not drink too much.
    I haven’t had a hangover in many decades.

    Ha, I called it! Tylenol came on the market in the mid-50’s and so did Eggos. Yes, Eggos, the frozen breakfast waffle, Leggo My Eggo.

    OBVIOUSLY, there is a link between pregnant women eating Eggo and autism. QED.

    As for “too much liquid,” What the Actual F???? An injection is something like half a milliliter. (0.5 ml)

    Crazy talk! Make it stop!

    I’m so frustrated by all the chaotic crap being thrown at the wall by the magat admin. I’m just waiting for roadkill f#cking kennedy jr. to proclaim eating dead uncooked possums shoveled up off the street prevents autism.

    I keep hoping all this is a bad nightmare, but I never wake up from it.

    I’m fascinated that aceteminophen allegedly causes something that doesn’t have a fixed definition… and is often diagnosed (and treated!) through symptomology best characterized as “too far away from social norms” (themselves undefined). Application to the prevalence of sociopathic/narcissistic behaviors manifested by the current administration requires further laboratory work, p-hacking, and generous funding from foundations whose endowments are traceable to the slave trade or illicit arms dealing; the evidence for “real-estate development fortunes cause later-generation autism” is at least as strong as that for aceteminophen.

    I don’t know who the woman is, I guess no one thinks she’s important enough to name

    I’m sure it will be Ofdonald soon enough.
    Particularly after enough childbearing women die from miscarriages or other preventable pregnancy problems when all abortion is completely outlawed, along with all medications and/or treatments for pregnant women. When enough women of childbearing age die from completely preventable problems and diseases (check out the effect of measles on pregnant women, as an example) the white replacement freaks will really start to lose their shit. Imagine all the entitled incels whining that they can’t get a woman, because in future news, all the childbearing white women will have been forcibly enslaved and kept captive by the “higher status males” the 8chan incel assholes so ardently worship as forced birthers.

    @1 You beat me to it. I’m sure J&J lawyers are already sharpening their knives and writing legal briefs even as we speak. J&J has more readily available cash then the entire net worth of the yahoos on stage for this particular shitshow.

  13. silvrhalide says

    Hmm… a 4 year term is just long enough for all the pregnant MAHA & MAGA women to deliver (in some cases anyway) at least some autistic kids… what happens when the MAGA & MAHA fools find out that they’re having autistic kids anyway, despite mainlining ivermectin and eschewing acetaminophen? Nothing nastier and more dangerous than a disillusioned (former) adherent.

    How many of them will finally connect the dots between measles and birth defects? The extensively documented birth defects with decades of scientific proof? Oops.

    I’m starting to think that the war on autism is related to the war on science in an unexpected way; I’ve noticed that a good proportion of scientists are autistic or at least on the spectrum; detail-oriented, task-oriented, capable of a sustained attention span, somewhat obsessive, resistant to social pressure …

    @3 Hemidactylus
    Tylenol is quite safe when you are not overdosing and when you have not already got liver damage. I suspect some people do not read the instructions and act like much helps much.
    That’s a problem with a lot of commonly taken medication, e.g. a lot of people will die from nurofen. You can bleed to death of an ulcer if you take too much, too long, got pre-existing aggravating factors, or take parallel medication that interacts with nurofen (or diclofenac, even more dangerous).
    Also a portion of these deaths will be down to suicides or tried suicides by people who DO know about the liver toxicity.

    @17 silvrhalide
    You have a touching faith in human rationality. Let’s see how many believers take today’s non-rapture as an opportunity to rethink their whole approach to reality. Alas, it won’t be many.

    The MAGA cult will never be much affected by bad empirical results.

    Women dying in childbirth is their plan. Women suffering from pain during childbirth is their plan. The Bible says so near the very beginning of the book (for those of them who can read and will read it). There are several posts here that think that this is a surprise. It isn’t. They have every reason to tell this lie.

    WRONG! It’s not Tylenol. It’s the Jews. They have been poisoning the wells again, just like the 14th century.
    Also, the eskimos.
