President Trump blasted followers on his social media platform Fact Social on Friday with this dire warning: “Don’t give Tylenol to your younger baby for nearly any purpose.” This assertion adopted a extremely publicized press convention final week wherein he and the Secretary of Well being and Human Companies, Robert F. Kennedy, Jr., steered—in contradiction to one of the best present medical proof—that acetaminophen, the lively ingredient in Tylenol, causes autism when given to pregnant folks or younger youngsters.
Why the president and HHS secretary are concentrating their efforts on this extraordinarily widespread ache reliever and fever reducer is unclear and neither has cited a lot high-quality proof for these claims. Whereas there are a handful of research displaying a correlation between acetaminophen use in being pregnant and autism charges, this doesn’t imply that the drug causes autism.
Tylenol is without doubt one of the solely drugs well being care suppliers can prescribe to deal with fever in being pregnant. Different ache relievers, reminiscent of ibuprofen (offered below model names reminiscent of Advil) and different NSAIDs (nonsteroidal anti-inflammatory medication), have been tied to an elevated danger of miscarriage, so they don’t seem to be typically beneficial. And there may be scant proof that Tylenol will increase the danger for autism—a fancy spectrum of neurological circumstances which have been linked to many genetic and environmental components. Extended fevers themselves are related to larger autism charges.

In the meantime researchers have proven in quite a few research that acetaminophen (often known as paracetamol) is protected and efficient in youngsters. And it’s among the many most generally pharmaceuticals in youngsters: some European research recommend that greater than 90 % of kids have taken it sooner or later.
“There is no such thing as a treatment in pediatrics that has most likely been given extra instances and in additional doses in my 25-plus-year profession than acetaminophen,” says Ian Paul, chief of pediatrics at Penn State Well being. “There have been very well-done scientific research which have regarded on the security and efficacy of that treatment, and it has confirmed over and over and over in beneficial doses to be each protected and efficient as a ache reliever and as a fever reducer.”
Docs have extensively prescribed acetaminophen to youngsters for each fever and ache because the Meals and Drug Administration permitted the over-the-counter drug Tylenol in 1955, although scientists nonetheless don’t know precisely the way it works. It’s typically thought-about protected to be used in youngsters when dad and mom or caregivers observe right dosing directions. However the American Academy of Pediatrics (AAP) says that infants below three months outdated ought to solely take it below a doctor’s directions and at a dosage primarily based on their weight.
“When their youngsters are sick, dad and mom and caregivers wish to do the whole lot they will to make their baby really feel higher. In some instances, giving youngsters drugs like acetaminophen could assist them really feel extra snug,” J. Routt Reigart, Chair of the AAP’s Committee on Medication, mentioned in a press release. “There are occasions when drugs will not be obligatory, so dad and mom ought to all the time discuss with their baby’s pediatrician if they’ve questions or considerations.”
A number of researchers have printed high-quality research investigating whether or not acetaminophen can be utilized safely for kids. A randomized managed trial printed in JAMA in 1995 regarded on the dangers of extreme unwanted side effects reminiscent of gastrointestinal bleeding, kidney failure and anaphylaxis (a severe and probably life-threatening allergic response) in additional than 84,000 youngsters within the U.S. who have been randomly assigned to obtain acetaminophen or ibuprofen to deal with fever. The researchers discovered that just one % of kids have been hospitalized (principally for infectious ailments) and the danger of hospitalization was equally low for each therapy teams. There have been no hospitalizations for acute kidney failure or anaphylaxis. A randomized medical trial printed in 1999 in Pediatrics that adopted up on 27,000 of those youngsters earlier than age two discovered that the danger of those occasions was nonetheless low with both treatment.
There are dangers to excessive or extended fevers, reminiscent of seizures. With gentle fevers, it’s extra essential to deal with the signs that come together with them—say, if a baby will not be consuming or consuming, or is in ache—than the fever itself. Untreated ache or discomfort may also lead to missed days of faculty or work.
Further analysis has proven that taking acetaminophen throughout being pregnant doesn’t enhance the danger of autism. Researchers in Sweden printed a research in JAMA final 12 months of greater than 2.4 million youngsters born within the nation from 1995 to 2019, 7 % of whom have been uncovered to acetaminophen within the womb. After they managed the information with siblings who weren’t uncovered to the drug, the researchers discovered that acetaminophen publicity was not tied to an elevated danger of autism, consideration deficit hyperactivity dysfunction or mental incapacity within the baby.
The truth that you don’t see one hundred pc of children develop autism after being uncovered to acetaminophen within the womb ought to be a sign about its common security with regard to neurodevelopmental results, says Brian Lee, a professor of epidemiology at Drexel College, who co-authored the Swedish research.
Melissa Witt, a spokesperson for Kenvue, the producer of Tylenol, shared the next assertion with Scientific American: “We consider impartial, sound science clearly reveals that taking acetaminophen doesn’t trigger autism. We strongly disagree with any suggestion in any other case and are deeply involved in regards to the well being dangers and confusion this poses for anticipating moms and oldsters.”
“Acetaminophen is the most secure ache reliever possibility for pregnant ladies as wanted all through their total being pregnant,” the assertion continued. “With out it, ladies face harmful selections: undergo by means of circumstances like fever which are probably dangerous to each mother and child or use riskier options.”
Like all drug, acetaminophen has its dangers. At excessive ranges it will possibly trigger liver toxicity, and kids have died from unintended overdoses.
And though acetaminophen is mostly protected at prescribed doses, it’s doable that new proof might present an adversarial impact, and medical doctors are always evaluating the dangers, Paul says. In latest a long time, some research steered that frequent use of acetaminophen in adults was linked with bronchial asthma, however Paul and his colleagues performed a randomized trial of 300 youngsters with gentle persistent bronchial asthma, printed in 2016, that discovered that acetaminophen was linked to asthmatic episodes about as regularly as ibuprofen. Throughout a follow-up interval of greater than 10 months, youngsters who acquired acetaminophen for ache or fever had 0.81 bronchial asthma episodes on common, in contrast with 0.87 within the group that acquired ibuprofen.
“The science by no means stops,” Paul says. However for now, the proof helps the security of Tylenol. “I confidently gave it to my very own youngsters,” he says.
