No link between acetaminophen use during pregnancy and adverse birth outcomes

6 hours ago (sph.unc.edu)

This paper says there are no adverse effects to the mother, but it does not mention possible adverse effects to the child beyond "birth health" and does not address the recent controversy about a possible link to autism.

  • Why would it need to? There is no medical controversy.

    There’s only a weak and now discounted statistical association that was seized upon by two disgraceful anti-science politicians to create a political controversy.

    • I can't figure it out. What is the actual reason they knowingly LIED about it?

      Some personal grievance against Tylenol brand?

      More graft from a competitor?

      Appease their conspiracy loving dumbass base?

      Destroy the scientific reputation of the US?

      Trump is actually that fucking stupid?

      All of the above?

And yet I still see MAHA defenders even on HN.

  • Some of us appreciate the "Eat fucking food, and do some exercise" part of it. The rest of it is a big meh. Not like I was looking to Rachel Levine as a paradigm either.

  • All smart people are curious about things outside their realms of expertise. Curiosity is one of the defining attributes of intelligence.

    The desire to discuss those things is also reasonable. Though I would agree that those without credentials should probably abstain from expressing any potentially harmful opinions when healthcare is involved, the freedom to ask questions or bring up interesting digressions is fundamental.

  • So you think the cobbler should be only a cobbler aye? Pinko much? That really does model technocracy and authoritarianism well. What's your argument that enforcing ignorance on the working class and restricting knowledge to utility works, or is superior to a free society?

    I expect, coming form one scholarly enough to be quoting elders, you'd have a strong one. Let's have it.

Just for the sake of honest balance, with minimal commentary and no opinions:

Acetaminophen and dementia correlation:

Note that it's also hard on the liver. A lot fatalities due to taking after hangovers, etc: https://www.medicalnewstoday.com/articles/322813 So if you insist, maybe take some NAC.

But apparently, Ibuprofen helps counter the dementia risk:

I am not not asserting any clever marketing here. I am merely citing public information. Noting all the above, I am confident it's perfectly safe for children and fetuses, and if posing any risk at all, applies strictly to full grown adults. No doubts about child safety have been expressed here.

  • "A lot fatalities due to taking after hangovers" no, that's not how acetaminophen fatalities happen. In fact, the article you cited specifically mentions "there is no scientific evidence that people with AUD (alcohol use disorder) who take the recommended dose of acetaminophen increase their risk of liver damage."

    Fatalities happen basically from: product stacking combination medicines people don't realize contain acetaminophen and/or multi-day accumulation exceeding max daily limit over multiple days.

    Chronic drinkers have impaired acetaminophen processing so they can't handle otherwise safe doses, but fatalities still typically occur in multi-day accumulation scenarios. Their safe daily max is ~half that of a non drinker.

    The effects of one round of acute drinking don't impair the liver in the same way. People are not dropping dead because they took a normal dose of acetaminophen for a hangover. Not that I'm recommending you start doing it, but it is a myth.

    • > Fatalities happen basically from: product stacking combination medicines people don't realize contain acetaminophen and/or multi-day accumulation exceeding max daily limit over multiple days.

      I find it obnoxious that NyQuil has taken over as the default brand people grab for cough syrup, for that reason. It has acetaminophen, while Robitussin or such have the other active ingredients without that risk.

      The typical person doesn't read and understand active ingredients, and it's lucky if they even check dosage instructions.

  • The liver toxicity is well known, and overdose is not uncommon.

    • A better policy fix would be to remove it from multi-drug products. Require it always be the only active ingredient.

    • > overdose is not uncommon

      Anecdotally, I hear about it far more in Internet comments like the parent than elsewhere. How common is it?

  • The first paper shows no evidence of any effect from Tylenol...? But yeah seems like lots of support for the ibuprofen protective effect, interestingly.

    • If you do start munching on advil; note there are rumors, by medical researchers, case reports, and more, that if you dig beneath the shiny surface to find, do show a lot of compelling data for GI damage, heart risk and other serious side-effects. And depending on how fair one wants to be with 'evidence' -- almost all wording describing NSAIDs as "protective", uses easy-to-miss but distinct qualifiers such as "potential" and other such vague 'maybe'-equivalents that alone have been used to suppress and dismiss many other...potential medicines. Sometimes, conclusive just means inspired. And sometimes ambiguity means certainty, depending on levels of inspiration involved.

      Of course, one might pause for a moment to consider just how potential the alluded benefits really are with ibuprofen, and ask why doctors aren't recommending it for mental health, or as a general health product. But that might point to the peculiar fact that there is substantially more evidence suggesting risk over health benefits, and the benefits really depend on what one wants to see. There is a reason it's not marketed as a health product, but with the way it's framed, it should be, nu? I mean, potential benefits sells a lot of snake oil and lowfat yogurt. Why not advil and acetaminophen?

      And by similar logic used to dismiss acetaminophen here as a health risk, eg because there's no link with autism/ADHD it's safe; why not apply the same logic to opiates? We could just say opiates do not directly cause, eg , parkinsons, or AIDS, therefore it's safe for babies. Myself, I never correlated acetaminophen with autism/ADHD, but I know it has more side-effects than listen on the bottle.

  • This article is about "how early a child is born or a child’s weight at birth". I don't know why we're talking about other possible negatives of Acetaminophen. Seems off-topic to me.

    • So a guy who beckons to "Keep HN weird." and has a history of non-strict adherence to subject titles with his/her own comments implies I must not challenge a title that claims "no adverse birth outcomes" from acetaminophen with closely related acetaminophen concerns and possible counter data? And that is some kind of special, golden? double standard?

      But truly, if I am the only rascal here on HN, deviating slightly from the subject title, I will gather the tinder. Let's burn me with haste!

is this just lying with statistics?

surely some abuse of the drug could lead to adverse reactions?

are they just arguing for specific doses to not have negative effects? (that would be true of a lot of things we consider harmful)

  • How could you think that anyone would argue that arbitrary doses of any medication are safe? Drinking too much water will kill you.
