One of the most well-known and often used over-the-counter painkillers is Tylenol, which is the brand name for acetaminophen. In pharmacology and medicine, acetaminophen occupies a singularly dominant position.

McNeil Laboratories established the brand in 1955. They packaged it like a red fire engine with the motto, “for little hotheads,” and promoted it as a medication to lower fever in children. Using the drug’s chemical name, N-acetyl-para-aminophenol, McNeil created the brand name Tylenol.

The first aspirin-free pain medication for children, Tylenol Elixer, was introduced by McNeil in 1955. After Johnson & Johnson acquired McNeil in 1959, the medication was sold over the counter the following year.

Tylenol is used by millions of people both as painkiller and a fever reducer. The drug is also widely used to treat minor discomfort and fevers brought on by illnesses like the flu, headaches, muscle pains, arthritis, and menstrual cramps. Tylenol is advised by the World Health Organization as first-line treatment for pain problems. This medication was first authorized by the American Food and Drug Administration in 1951.

In the United States, acetaminophen is available over-the-counter (OTC) in a variety of dosage forms, including regular (325 mg) and extra-strength (500 mg) oral tablets or capsules, oral liquids with quick release, chewable or orally disintegrating tablets, and rectal suppositories. In the United States, acetaminophen (Ofirmev) is also available by prescription in an intravenous (IV) form.

Around 50 million American consumers in the United States use products containing acetaminophen each week, with more than 25 billion doses being used annually.

Acetaminophen is found in over 600 prescription and OTC products in the U.S. like antihistamines, decongestants, cough suppressants, and diphenhydramine.

Common over-the-counter (OTC) drugs in the US that contain acetaminophen are as follows.

  • Delsym NightTime Multi-Symptom used for cough, runny nose, congestions, headache, cold and flu
  • Excedrin used for migraine headache pain relief
  • Robitussin Flu used for headache, runny nose, cough, congestion and flu
  • Sudafed PE Sinus Headache used for sinus headache
  • Theraflu Sinus and Cold used for sinus headache, congestion, cold, flu symptoms
  • Tylenol PM used for mild pain relief combined with an antihistamine OTC sleep aid

Mechanism of Action of Tylenol

The mechanism of action of Tylenol is not fully understood and it is still under research.

The available research findings indicate that the drug interferes with the prostaglandin synthesis which is responsible for pain sensation in our body. Two isoforms of cyclooxygenase, COX-1 and COX-2 is involved in prostaglandin synthesis, which is blocked by Tylenol. Acetaminophen has no peripheral anti-inflammatory benefits because it does not inhibit cyclooxygenase in peripheral tissues.

The direct impact of acetaminophen on the brain’s heat-regulating areas is presumably what causes its antipyretic effects, which include peripheral vasodilation, sweating, and a loss of body heat.

Tylenol, Pregnancy and Autism

The National Institutes of Health and the Agency for Health Care Research and Quality conducted its own study in October 2019 under the direction of Xiaobing Wang, M.D., and colleagues from the Baltimore-based Johns Hopkins Bloomberg School of Public Health.

The study came to the same conclusion that acetaminophen use during pregnancy was associated with an increased risk of autism and ADHD.

In September 2021, issue of the journal Nature Reviews Endocrinology, reported the shocking truths about Tylenol and pregnancy. New scientific evidence suggests that Tylenol or generic acetaminophen while pregnant may raise the risk of autism in the baby, which is the basis for the acetaminophen lawsuits. The reports of the research studies triggered the parents of autistic children to file lawsuits, suing Tylenol manufacturing companies.

In September 2021, the United States Food and Drug Administration released a statement regarding Tylenol during pregnancy, and concluded that the studies were “too limited to make any recommendations based on these studies at this time. Because of this uncertainty, the use of pain medicines during pregnancy should be carefully considered. We urge pregnant women to always discuss all medicines with their health care professionals before using them.”

Animal studies show that acetaminophen exposure during pregnancy can affect foetal development and raise the likelihood of neurodevelopmental disorders including autism. One of the suggestions from the studies is to add a notice against acetaminophen usage during pregnancy to all products containing the drug.

Consistent exposure or Tylenol during pregnancy is also reported to have other issues like

  • ADHD (Attention Deficit Hyperactivity Disorder)
  • Undescended testicles
  • Neurodevelopmental issues
  • IQ level deficits
  • Behavioral issues
  • Sleep issue
  • Early puberty in girls
  • Male fertility problems

Need to solidify your case with a thorough record review?

Is this the first lawsuit against Tylenol manufacturers?

No. Tylenol is involved in numerous lawsuits associated with liver damage. A claimant sued McNeil Consumer Healthcare, in 1993 on the grounds that it neglected to warn that combining alcohol with the drug’s key ingredient, acetaminophen, could harm the liver.

Benedi, the claimant received $8.8 million from a federal court jury, which was divided into $7.855 million in compensatory damages and $1 million in punitive damages.

Numerous complaints have been made since 1994, claiming that taking Tylenol damaged their livers. By the end of June 2013, 187 people had filed lawsuits across the nation, with at least 14 of those claims being filed in New Jersey, the state where Johnson & Johnson is based, and 74 of those cases being filed in federal court. 13 federal MDL litigation out the 233 plaintiff-filed federal lawsuits are still pending as of April 2019.

Know How to File a Tylenol Autism Class Action Lawsuit

Are you the parent of a child with Autism Spectrum Disorder or ADHD? Do you suspect Tylenol intake, the culprit?

Consult a Tylenol lawsuit lawyer and proceed with a case evaluation.

If the mother was seeing a doctor or ob-gyn while pregnant, the mother’s medical records are a typical technique to prove it.

If the plaintiffs can demonstrate that they used Tylenol or acetaminophen products over an extended period of time while pregnant, their cases will be stronger.

Potential evidences in Tylenol class action lawsuits could be the following

  • Acetaminophen purchase receipts
  • Records from the child’s doctor stating that the exposure to acetaminophen caused a neurological issue
  • Records from the child’s therapist or psychiatrist
  • Any documentation from medical practitioners regarding the use of Tylenol during pregnancy

The claim should not have any evidence of a family history of autism, pregnancy problems, or other known risk factors for autism and neurological disorders.

Despite all the increasing evidence against Tylenol and acetaminophen, there is currently no black box warning label on these medications alerting consumers and physicians to any potential connection between Tylenol usage during pregnancy and Autism or ADHD.

Furthermore, there is no guidance regarding the levels that may or may not be deemed safe for expectant mothers. The only way to be safe is to seek medical advice before taking Tylenol during pregnancy.
