Can Taking Tylenol Make You Regret Later? Know the Health Hazards

In December 2022, Click2Houston reported on advertisements implying that the use of acetaminophen during pregnancy might be a factor in the development of ADHD, autism, and learning disorders in certain children. However, health experts have differing opinions on Tylenol use, which contains acetaminophen, and its potential connection to these conditions and others.

Nevertheless, there are a few doctors who have openly shared their perspectives on the use of Tylenol. One such doctor is Dr. Roberta Ness, the former Dean of the University of the Texas School of Public Health and a scientific consultant for Autism Justice. Dr. Ness firmly believes that Tylenol use during pregnancy leads to autism in children.

A study published in Nature, which involved 91 scientists around the world, suggests that women should avoid using this pain reliever unless it is necessary. The study also highlights the potential adverse effects of prenatal exposure to acetaminophen on fetal development, leading to various reproductive, urogenital, and neurodevelopmental disorders.

Additionally, Dr. Ness disclosed that 10% of women use Tylenol for an extended period, and this specific group requires caution. She recommends obtaining necessary information and using the medicine for a shorter duration.

In this blog, we will shed light on health risks associated with Tylenol use and guide in seeking legal assistance if affected by it.

Tylenol Can Blunt ICI Response for Cancer Patients

In June 2022, Medicine Matters discovered a correlation between acetaminophen levels in the bloodstream and unfavorable outcomes in individuals undergoing ICI (Immune Checkpoint Inhibitors) therapy for advanced cancer. Researchers, in a publication in Annals of Oncology, presented at the 2022 ASCO Annual Meeting in Chicago, Illinois, USA, emphasized the need for further investigation into the impact of acetaminophen on immune function. They recommended that cancer patients avoid using this drug.

To support their assertion, researchers analyzed publicly available serum metabolomics data from 297 patients enrolled in CheckMate 025 trial for advanced renal cell carcinoma, who received nivolumab. Their analysis revealed that patients who had detectable levels of acetaminophen or acetaminophen glucuronide at the start of treatment had a significantly poorer chance of survival compared to those who did not take acetaminophen.

Acetaminophen and Altered Reproductive Function

Chris Kresser, a renowned clinician and Functional Medicine educator, asserts that acetaminophen acts as an endocrine disruptor and impacts reproductive health. Referring to a study, he mentions that rats exposed to acetaminophen gave birth to female offspring with decreased egg count, smaller litters, and smaller ovaries at reproductive age. Male rats experienced reduced sperm progenitor cells during early life.

Researchers attribute these effects to acetaminophen’s influence on prostaglandins. In humans, prolonged use of this drug during pregnancy, exceeding four weeks, is associated with an increased risk of infants being born with undescended testicles. Additionally, it can lower testosterone production in the fetal testes, affecting male development.

Filing a Legal Complaint When Affected by Tylenol

In April 2023, The Conversation reported on a tragic incident of Larissa, a Canadian college student who passed away at 21 from health complications due to an overdose of acetaminophen.

Her sister, Darby, recollects Larissa’s rapid health deterioration. She said that within a week of Larissa taking the medicine she had to undergo a liver transplant. Finally, her health deteriorated due to a wide range of complexities. Their family is still unaware of how acetaminophen led to Larissa’s death and shares that they might never get closure on this.

Larissa is not the only one who was affected by acetaminophen. There are plenty of other women who have witnessed ADHD and autism in their kids due to Tylenol use during their pregnancy. If you or anyone you know has undergone a similar experience, they can file a Tylenol lawsuit for autism and get the justice and compensation they deserve.

TorHoerman Law asserts that individuals must gather all evidence to support their lawsuit against Tylenol for ADHD, autism, or any other health disorders. It is essential to establish that Tylenol was used during pregnancy and that the concerned child was diagnosed with any neurological disorder, supported by scientific and documentary evidence. Finally, the settlement could be over $500,000 based on the strength of your legal claim and progress of multi-district litigation.


It’s a known fact that Tylenol use during pregnancy leads to a wide range of health hazards in women. Hence, it is a wise decision to search for alternatives that work well. Some alternatives to acetaminophen include curcumin, clove oil, magnesium, and CBD oil. However, consult your doctor to decide on the right dosage and duration of use.

While the world is still divided on the use of Tylenol, individuals must take accountability for their situation. Therefore, if the use of acetaminophen has caused you or your child to suffer, it is necessary to address it medically first and then consider seeking legal aid.
